The Importance of Indoor Air Quality on Education Outcomes in Pre-K12 Facilities, and How Elara is Paving the Way

It has been well established for some time now that indoor-air quality (IAQ) significantly impacts  the learning environment of students, their health, and their educational outcomes within schools. Students, Faculty, Designers, and many others were all reminded of this during the COVID pandemic. Maintaining enhanced indoor air quality in schools will continue to be a priority for School Districts around the country, and with good reason.

IAQ and Student Health:

Indoor air quality is a crucial aspect of student health. Poor air quality in classrooms can contribute to a range of health issues, including headaches, dizziness, and respiratory problems. A study by the Environmental Protection Agency (EPA) found that exposure to indoor air pollutants as a result of poor ventilation and filtration is a leading cause of asthma and other respiratory diseases in children. Poor indoor air quality can therefore lead to absenteeism, resulting in missed classes and decreased academic performance.

Enhanced Ventilation & Student Performance:

Several studies have shown that enhancing ventilation in classrooms positively impacts student performance. A study conducted by the Lawrence Berkeley National Laboratory found that increasing ventilation rates in classrooms resulted in a 14-15% increase in test scores. The study also found that improving ventilation rates led to a 3-4% increase in attendance rates. A similar study by the Harvard T.H. Chan School of Public Health found that students in classrooms with enhanced ventilation had significantly better cognitive performance

Improved Ventilation Systems:

To achieve enhanced ventilation in classrooms, schools must improve their ventilation systems. Schools can increase ventilation rates by increasing the amount of outdoor air entering the classroom and by improving the air filtration systems. Installing energy-efficient ventilation systems and air filters can reduce the amount and cost of energy consumed while also improving indoor air quality (and, with an additional benefit of providing unused monies for direct educational purposes).

Elara Design Philosophies that Provide Enhanced IAQ:

Historically speaking, typical Architectural and HVAC design for the K12 market was optimized around cost efficiency, not optimization of classroom or building ventilation. Vintage HVAC systems such as unit ventilators, multizone, and Variable-air-volume (VAV) systems fall short when compared to more modern approaches available to design consultants.

Elara strives to provide enhanced classroom IAQ by designing systems which supply filtered, conditioned 100% outside air from a dedicated Outdoor Air System (DOAS) directly to each classroom space, independent from the heating and cooling systems. We have successfully paired DOAS systems with equipment designed to satisfy the heating and cooling requirements of each space such as Variable Refrigerant Flow systems, Heat Pumps and Fan Coils. Opportunities to increase ventilation rate and delivery effectiveness also exist with systems such as Chilled Beam and Induction Displacement. These approaches to design can enable precise control of ventilation rates within spaces regardless of the heating and cooling loads, resulting in superior indoor air quality throughout the building.

As with any new construction or major renovation project, there are many factors that can dictate the decision making process of the design team. We welcome the opportunity to provide more information and discuss how we can help you improve the IAQ in your facility to positively impact the performance of students and faculty. Come visit us at IASBO on May 3-5 at the Peoria Civic Center (Booth 809) or reach out to Jim Gibson at jgibson@elaraeng.com.

New City of Chicago Cooling Ordinance

As many of you are aware, the City of Chicago passed a new cooling ordinance on June 22, 2022, which was put into full effect as of July 2, 2022. The intent of this ordinance is to provide occupants of new and existing residential buildings over 80 feet tall and low-rise buildings with more than 100 dwelling units (including residential portions of mixed-use buildings) relief from unseasonably hot weather via at least one (1) common indoor gathering space when central cooling is not available. Housing for older persons is also addressed by the ordinance but subject to separate requirements.

For residential buildings within the identified groups that are not housing for older persons, the common gathering space (i.e., meeting rooms, party rooms, and exercise/fitness centers) must be served by cooling equipment independent of the building’s central cooling system and must be accessible to all building residents. The common gathering space must maintain cooling and dehumidification thresholds identified by the ordinance, be open to residents of the building, and operated to maintain “safe” indoor conditions when the heat index for the City of Chicago exceeds 80°F.

Key Dates

  • April 30, 2024: Temporary Cooling Equipment Exception Expiration
  • Temporary or portable cooling equipment for at least one (1) indoor common gathering space will be acceptable to meet the ordinance requirements until April 30, 2024.
  • May 1, 2024: Permanent Cooling Equipment Required
  • Permanent cooling equipment for at least one (1) indoor common gathering space must be in place and operational by May 1, 2024. Temporary or portable equipment will no longer be acceptable as of this date.

Recommendations

Considering the extended lead times for equipment and materials that have become commonplace within the construction industry, building owners and operators should be proactive in planning for their building’s compliance with the City of Chicago’s Cooling Ordinance. If a common gathering space without permanent, independent cooling and dehumidification is not currently in place for building residents, temporary cooling units should be procured to ensure compliance during unseasonably warm weather in the immediate term. Simultaneously, design efforts should commence for a permanent solution to be operational by May 1, 2024.

Please contact Elara’s Commercial / Multifamily Practice Leader, Matt Swanson, at mswanson@elaraeng.com to learn more about the City of Chicago Cooling Ordinance, how it applies to your specific building, and to obtain assistance in preparing your building for compliance.

Prepare your Building for Extreme Cold Weather

As many of you are aware, Chicagoland is forecasted to experience severe cold temperatures over the next week with lows occurring at or below zero with the forecasted overnight low on Christmas Eve being -4˚F.  The forecast projects temperatures that will test the limits of the heating capabilities of your equipment. In advance of this and other extreme cold weather events, it is important to make sure your building is prepared.

We recommend taking the following steps to ready your building for the extreme cold, especially if you have made changes to how your ventilation system is operating since last winter, or you have new space heating equipment:

  • Turn off all non-critical exhaust systems (i.e. residential kitchen and toilet exhaust)
  • Temporarily reduce ventilation where possible
    • DO NOT turn off 100% Makeup Air Units (MAUs)
      • If 100% MAUs shut down unexpectedly and cannot be restored, we advise shut down of the associated toilet and kitchen exhaust systems
    • Override unoccupied and overnight setbacks to occupied
    • Avoid scheduled shutdowns of systems
    • Avoid turning heating related equipment off
    • Verify all coil pumps are operational
      • DO NOT shut coil pumps off
    • Maintain continuous operation of all heating related pumps
    • Minimize infiltration
      • Keep doors, windows and other openings sealed
      • Add temporary heat where infiltration can’t be controlled or where you have observed cold temperatures in the past
    • Keep blinds and shades closed on windows at night and those not receiving direct sunlight during the day
    • Perform a system check of all heating critical equipment
    • Verify the operation of all low-limit safeties such as freezestats to protect equipment
      • Ensure the sequence of operation is followed upon a freezestat trip (Example: outside air dampers properly shut and can be reopened)
    • Test the operation of all backup or redundant heating equipment and sequences not normally used
    • Verify the location of isolation valves, verify their operation and understand when to use them
      • During an emergency situation where a pipe, coil or other system has frozen, the reliability, and proper use of isolation valves is critical
      • Isolate the leak to as local an area as possible.
      • Take care not to close the wrong valve (essentially stopping the flow of water)
        • Water at rest is much more likely to freeze.  Therefore, do not risk further freezing of the system by closing the wrong valve, should isolation be required
  • To the extent possible, remove ice and snow from air-source heating equipment such as VRF and air-source heat pumps
    • Also remove snow from the areas immediately surrounding the equipment

– Matt Swanson, Principal / Practice Leader – Elara Engineering

Life Before Elara.  

Having grown up in Menomonee Falls, Wisconsin (outside Milwaukee), Adam attended the University of Wisconsin-Platteville (home of the Pioneers and Pioneer Pete) where he also worked as a Co-Op Intern at Pearson Engineering in Madison, Wisconsin.  Tempted by warmer weather and a job offer upon graduation, Adam headed south to Illinois to take a job with Elara Engineering – and hasn’t looked back since!!

Prior to his current role and responsibilities at Elara Engineering, Adam was a Senior Mechanical Engineer and a Mechanical Engineer at Elara.

 

Life Outside Elara. 

Adam, his wife, and his two sons currently reside in Batavia, Illinois where he is an active BBQer and sometimes woodworker, fisherman, and rock/wall climber when time allows. When pressed about his backyard BBQ acumen, he revealed that his smoked brisket is always a party favorite among his many offerings of smoked turkey, pulled pork, beef ribs, smoked wings, and baby back ribs.

Although typically utilizing indoor vertical climbing walls, Adam – with ten years of climbing experience – has scaled several outdoor faces including Cleopatra’s Needle at Devil’s Lake, Wisconsin.  Adam’s love of fishing – unabated since his childhood – started when he and his father would head out after dinner every night for their own personal fishing derby – with the loser having to scoop ice cream for the winner upon their return.

With a hectic work and personal life where his sons keep him busy and entertained, Adam has had to limit his time and allegiance to only one professional sports team…from one football team: the Green Bay Packers – to another football team: Liverpool FC.

Elara Wins ASHRAE Technology Award for MEP Upgrades

Elara Engineering’s design team has earned a 2022 ASHRAE Region VI Technology Award for energy retrofits that included innovative MEP upgrades at Hanover House in Chicago’s Near Northside Neighborhood. In addition to the recognized achievement, Elara’s team was able to secure $33,924 in incentive funding for obtained energy efficient equipment.

Constructed in 1962, Hanover House (21 Goethe) is a 19-story, 166-unit, 165,000 square-foot building with a heated pool, sundeck, common laundry, heated indoor parking lot, and commercial space that currently houses a restaurant.

Master Plan

Before design work was initiated, Elara’s Master Plan identified and prioritized projects to replace/enhance major MEP systems in phases based on Condominium Association financial constraints and a stated goal to reduce carbon emissions. Prioritization and planning enabled full occupancy of the building throughout construction and utilized creative sequencing to reduce the overall cost of all projects.  Additional efforts to reduce project costs while addressing the need for larger cooling capacity included a 30-day load study that avoided the need and cost to increase the building’s electrical service.

Phase I Projects

First prioritized projects replaced the existing heating boiler plant, dual temperature and hot water pumps, and makeup air unit (MAU) with a new, modular condensing boiler plant, rooftop MAU, and open protocol DDC system as well as new horizontal dual temperature, domestic and cold-water piping.

Phase II Projects

Second prioritized projects installed a new high-efficiency chiller that utilizes multiple compressors and refurbished the building’s existing cooling tower.

Project Innovations

Because inadequate dehumidification and spatial constraints within the building’s penthouse negated a “like-kind” replacement of the building’s undersized MAU, ventilation to corridors is now provided via a new 100% outdoor air, rooftop MAU equipped with MERV 14 filters and a dehumidification strategy that uses hot air bypass.

Opening Celebrated for an Elara MEPFP-Designed Elementary School

To commemorate the opening of the newly constructed Big Timber Elementary School, District 300 recently held a ribbon-cutting ceremony in August with community leaders, project participants, school board members, and school district personnel in attendance. Big Timber Elementary School addresses population growth in the District’s western portion in Hampshire and Pingree Grove, Illinois. With its 40 classrooms, two playgrounds, gym, media center, multi-purpose room, kitchen, specialty rooms with sensory adaptation, and administrative and mechanical spaces; the new 2-story, 100,625 square foot building will accommodate faculty, support personnel, specialists, and students from kindergarten to fifth grade. Elara Engineering was pleased to partner with Dewberry Architects Inc. (Architect) and Lamp Incorporated (General Contractor) on this exciting project.

Elara’s Contribution
Elara’s MEPFP Design Team provided Schematic Design, Design Development, Permit/Bid/Construction Document, Bidding, and Construction Services to District 300 for the new school building. Specific design elements included mechanical/HVAC systems (ventilation, boiler/chiller plants, space conditioning, ductwork, piping, and controls), electrical (normal/emergency power distribution, interior/exterior lighting, fire alarm system), and plumbing (including fire suppression).

Elara also completed energy modeling and a building optimization study to support the early planning phase and to identify the most effective building design.

“District 300 is excited to recognize and celebrate the opening of Big Timber Elementary School,” said Superintendent Susan Harkin during the celebration Tuesday. “Many individuals contributed to the development of this beautiful building, and we cannot thank them enough for their hard work. I know this school will be a source of pride for us for many years to come.”

Project Highlights and Innovations

  • As a result of its modeling effort and building optimization study, Elara not only delineated the best design for Big Timber Elementary, but the project further developed the school district’s model school MEP systems (previously updated 14 years prior) and included energy efficiency enhancements and airborne infectious contaminant control strategies.
  • Big Timber Elementary School’s gymnasium – designed to ICC500 Storm Shelter Standards — is the District’s first storm shelter.
  • To accommodate likely future population growth in the District, Elara’s Design Team:
    • Ensured that the hot water boiler plant, which includes two 3,000 MMBTU fire tube condensing boilers located in the building’s second floor, was sized to support a future addition which was designed a short time later and constructed in time for the 2022/2023 school year.
    • Ensured that the chiller plant, which includes two 90-ton air cooled chillers located on the roof above the building’s second floor, was also sized to support a future addition.

Record Number of 6 Students Complete Elara’s 2022 Summer Internship Program

As in previous years, Elara’s summer interns were once again embedded within market-focused teams working side-by-side with our engineering experts on a wide variety of multidisciplinary projects.

The 6 interns, as active members of Elara’s technical design teams, were tasked with completing field surveys at various sites, utilizing AutoCAD (2D) and REVIT (3D) drafting/modeling software to support the preparation of engineering drawings, executing basic engineering calculations, and completing an end-of-summer tour of a project currently in construction.

With the goal of introducing the interns to a wide variety of topics relevant to our industry, other elements of Elara’s Summer Internship Program included weekly presentations from our Principals, Team Leaders, Project Engineers, and other firm leaders. The variety of topics included “Plumbing Jeopardy”, an “Intern to Full Time Employee” panel discussion, “The Past, Present, and Future of CAD/BIM”, “Insights from the Principals”, and technical presentations for all of Elara’s MEPFP disciplines and markets.

Elara’s 2022 Summer Internship Program culminated in a joint presentation by the interns to Elara leadership (followed by a wonderful lunch celebration) covering a technical topic each student chose to learn about throughout the summer. Specifically, through both independent research and collaboration with our engineers, the interns developed presentations that exhibited what they learned during their internship, took a deeper dive into their chosen topic, and taught our firm’s leadership something new.

My summer internship experience at Elara was amazing. I had an opportunity to work alongside a dedicated team of engineers that helped me grow not only in my drafting and design skills, but also in my communication, collaboration, and critical thinking skills. My favorite experience was the onsite visits because they allowed me to see – right before me — what I was drawing on CAD.

Prepare Your Building for Extreme Warm Weather (and Keep Its Occupants Cool!)

In summer, the Chicagoland area is often forecasted to experience extremely hot temperatures with high humidity that will test the limits of the air-conditioning capabilities of building cooling equipment.

In advance of this and other extreme weather events, it is important to make sure buildings are prepared to provide comfortable conditions for their occupants. We recommend taking the following steps to ready your building, as applicable:

  • Override unoccupied and overnight setbacks to occupied
  • Avoid scheduled shutdowns of systems
  • Avoid turning cooling related equipment off
  • Maintain continuous operation of all cooling related pumps
  • Minimize infiltration by keeping doors, windows and other openings sealed and shut
  • Keep blinds and shades closed on windows during the day to avoid direct sunlight
  • Perform a system check of all air-conditioning critical equipment
  • Verify the operation of all backup or redundant air-conditioning equipment not normally operated
  • Ensure make-up water feeds to cooling towers are fully functional and water levels are able to be maintained
  • Ensure condensate drains and traps have been checked and are functional
  • Proactively change filters in fan coils and air-handling equipment
  • Enhance dehumidification by lowering cooling coil discharge air temperatures and slowing down fan speed, where necessary. Ensure equipment is operating within manufacturer guidelines. Adjustments to DX equipment should be made by a service contractor authorized by the manufacturer
  • Set all thermostats to typical design indoor conditions of 74°F-75°F
  • Sub-cool event spaces and venues prior to scheduled events

Elara Undertakes Design for Tribune Tower Adaptive Reuse Project

A Renewed Chicago Landmark

Working alongside architect Solomon Cordwell Bunez (SCB), Elara Engineering recently completed the MEPFP design for an adaptive reuse project that converted the iconic 34-story Tribune Tower and surrounding buildings into 162 luxury condominium units with amenity and retail spaces, while respecting the building’s Chicago landmark status.

Originally constructed in 1925, Tribune Tower is one of Chicago’s most recognized historic landmarks. In 1935, the Radio Building was added to the site, followed by the Television Building in 1950. In 2018, the Chicago Tribune newspaper vacated the building and planning began to transform the site.

In addition to conversion of the Tribune Tower to condominiums, four additional floors were added to the northeast side above the TV Building, providing a modern, glass complement to the existing limestone facades and creating a new elevated courtyard. A full luxury amenity program encompasses several unique spaces, including a series of terraces at the tower’s crown that gives residents a one-of-a-kind experience beneath iconic, gothic buttresses.

Creative Solutions

As the project’s MEPFP engineer responsible for the design of new major MEPFP equipment and infrastructure throughout the existing tower and addition; the depth of experience, creativity, and problem-solving ability of Elara’s team, led by Multifamily Practice Leader, Matt Swanson, enabled the design to exceed the City of Chicago’s sustainability ordinance. Project highlights include:

  • Elara identified the opportunity and confirmed the ability to reuse the building’s existing emergency generator, ComEd vaults, diesel fire pumps, and existing chilled water plant that utilizes a river water condensing system.
  • Indoor air quality is maximized through the use of dedicated outdoor air systems that employ MERV-13 filtration, provide ventilation directly to each condominium unit to minimize the mixing of air, and use self-regulating exhaust systems.
  • Condominium units have smart thermostats with remote sensors and are served by four-pipe fan coil units installed in enclosures with ducted return and variable ventilation systems (including makeup air and toilet, kitchen, and dryer exhaust system).
  • New direct digital controls (DDC) were designed to serve all major mechanical systems.
  • Interior common area lighting is controlled by a state-of- the art, multi-zone dimming system with code required occupancy and daylight sensors. Exterior and facade lighting is controlled by a building lighting multi-zone dimming system.
  • Electric vehicle charging infrastructure was designed to support the entire parking garage.
  • The main domestic hot water plant consists of high-efficiency water heaters located in the mechanical penthouse of the north tower while the hot water return heat exchangers are located in the 2nd floor mechanical room. A dedicated sub-water heater plant is located at the base of the highest zone for zone isolation.

Pressure Increasing to Decarbonize Buildings

Sustainability and carbon reduction are quickly shifting from voluntary endeavors to mandatory ones. For building owners and managers, it will be one of the greatest driving forces influencing building compliance over the next several decades as policy makers and regulators continue to increase their focus (and demand) to achieve sustainability targets and mitigate climate change. Soon, sustainability improvements will no longer be optional, and carbon neutral targets will have to be met. In many cities and counties around the country, including New York, Washington DC, Denver, and Boston, this is already a reality. In 2021, Chicago convened a Building Decarbonization Working Group and has been following the path forged by New York for many years. It is highly likely that within the next couple years Chicago will have a similar Decarbonization ordinance and, therefore, it is critical that owners are proactive to avoid potential fees and/or reduced property value.

Construction of new sustainable buildings is relatively common and straightforward. However, bringing existing buildings up to modern standards is significantly more difficult which of course, also means at a much higher expense. In short, moving existing buildings towards sustainability is a balancing act among time, capital, and technology and to successfully balance these constraints, it is critical to prioritize the retrofit and upgrade process. On the other hand, buildings and owners will benefit greatly from reduced energy costs and many buildings will be able to meet carbon reduction compliance metrics by implementing measures with attractive paybacks.

To this end, every building owner should be thinking about or have already completed an energy audit to determine the most cost-effective path to compliance and to benchmark current performance. Building portfolio managers should consider benchmarking their properties to focus efforts on the poorest performers first. Building owners should turn to an experienced MEP consulting firm to provide this highly beneficial energy audit and prioritization plan.

Because audits, upgrades, and renovations will likely not remain optional forever, incentives for early adopters will likely eventually give way to penalties for late adopters. Proactive owners will enjoy numerous benefits, including time for decision making and increased property values. As with any significant market shift, the initial challenges presented also represent a substantial opportunity.

Elara Project Wins ASHRAE International Award!

After receiving recognition at the local and regional level, an Elara Engineering new construction project – 3833 North Broadway Urban Geothermal Multi-Family – has received ASHRAE’s highest honor; a first place International-Level Award.

This project represents Elara’s fourth International-Level ASHRAE award and we congratulate our team of dedicated experts: Don McLauchlan, Dustin Langille, Bhupendra Tailor, Nick Capretta, and Mark Rockwood, for their contributions to this internationally recognized project.  We also thank the owner, managers, and staff of 3833 North Broadway for their commitment to this highly sustainable, energy efficient project and for the trust and confidence they had in Elara Engineering to bring it to completion.

3833 North Broadway Urban Geothermal – New Construction

  • MEPFP design of 8-story, 228,960 square foot apartment building with 134 residential units, indoor heated parking, retail spaces (20,777 sf), fitness center, community area, outdoor running track
  • Geothermal heating and cooling, solar PV, exhaust air heat recovery, shower drain heat recovery, sidewalk snowmelt and demand control strategies
  • Actual EUI: 22 kbtu/ft²

Key Innovations

  • 60-well geothermal field located underneath the building structure on a limited urban site.
  • Detailed energy modeling along with a parametric analysis allowed for careful sizing of the geothermal field to minimize project costs.
    • Detailed modeling reduced the field size by an estimated 40% over standard designs for geothermal systems in Chicago
  • The simplicity of the design allowed the building owner to assume portions of the project management duties and to utilize several contractors that had worked on previous smaller projects with them. This resulted in project costs well below similar projects in Chicago.
  • The building’s low actual EUI of 22 kbtu/ft² saves $159,555/year over the baseline model EUI of 44 kbtu/ft².
    • The geothermal cost of approximately $500,000 is offset in just three years compared to the baseline building (1.5 years when compared to a typical Chicago new construction building), not including any avoided costs such as large central chiller/boiler plants.
  • Energy savings result in an approximate annual reduction of 1,115 metric tons of C02; the equivalent of removing 242 passenger cars or 134 homes from the energy grid.

With careful planning and a simple design, Elara shows that – with this project – buildings can be constructed with sustainable and energy efficient features such as geothermal at competitive costs.  Additional project details can be found here.

A New Year- An Opportunity to Update or Obtain a Reserve Study

What is a Reserve Study?                                         

A Reserve Study is a formal review of a building’s major common elements, including Mechanical, Electrical, Plumbing, and Fire Protection (MEPFP) systems, at the time the study is performed.  Typically, a Reserve Study is performed by one or more professionals and consists of site visits and the preparation of a written report. The report includes a master spreadsheet allocating budget costs for system and component repairs and replacements that are anticipated within a 20-year planning horizon.

 

The Benefits of a Reserve Study

  • Supports a condominium association’s requirement to maintain an appropriate level of capital within their financial reserves.
  • Provides a decision-making framework to prioritize and plan for major repairs and capital projects.
  • Documents the potential need for common fees, assessments, and loans if necessary.
  • Protects condominium unit owners from unexpected large assessments or debt service on loans for capital improvement projects.

A Reserve Study is not only important for current condominium owners, but for future buyers, lenders who may be called upon for loans, and insurers looking to establish long term relationships with well-run and adequately funded community associations.

 

Reserve Study Elements

 

 

 

 

Data Acquisition

  • A review of (1) existing building drawings; (2) the previous Reserve Study and/or allocation spreadsheet (if a previous study was completed); and (3) available system documentation.
  • Staff interviews.

Field Reviews

  • An on-site review of the building’s common element systems to generate/confirm an inventory of major components and equipment with nameplate data (e.g., manufacturer, basic specifications, etc.) that can be used to request additional information, as needed; and to visually ascertain and assess the physical condition of each piece of identified equipment or major component.

Data Analysis & Recommendation

  • Upon evaluation of available information and taking into consideration age, condition, and remaining useful service life; recommendations are developed for the timing of repair or replacement for capital projects of $5,000 or greater that should be budgeted to maintain the property for 20 years.

Report

  • A provided written report will include an executive summary, project methodology, a physical analysis section, a financial analysis section (with master spreadsheet), and recommendations.

 

Added Valued from Elara Engineering

Enhanced MEPFP Solutions

In addition to the above-described elements relative to MEPFP systems, Elara’s experienced engineering team also includes – as part of its Reserve Studies — the preliminary identification of MEPFP system alternatives that offer ancillary building benefits such as increased energy efficiency, enhanced occupant comfort, beneficial technology upgrades, and significant utility cost savings, as applicable.

It should be noted that alternative systems evaluated as part of any reserve study and their associated costs are intended to be used as a budgeting tool for future planning. Independent studies (often termed “Schematic Design”) are frequently recommended when it is time to undertake the capital project in order to further detail and update cost estimates and determine the project basis of design.

 

Real-World Cost Estimates = Better Planning

As described above, cost estimates for a Reserve Study are derived from recent equipment cost information provided by vendors. However, to provide a more complete picture of the total potential costs involved, Elara’s cost estimates are further extrapolated to include consideration for current market trends based on similar, recent experience. Elara’s proprietary cost estimating tool is based on real-time data of various construction-related activities from our design and construction experience in lieu of theoretical construction estimating methods. In this manner, building stakeholders gain a much more complete view of the true costs that may be incurred over a 20-year planning period.

Experienced Engineers

Elara’s reserve studies are performed by professional engineers to ensure that building stakeholders receive the full depth and breadth of Elara’s experience identifying and designing MEPFP upgrades in similar buildings.

Prepare your Building for Extreme Cold Weather

As many of you are aware the Chicagoland area is forecasted to experience severe cold temperatures over the next few days with lows occurring at or below zero with the projected overnight low on Tuesday being -8degF. The forecast projects temperatures that will test the limits of the heating capabilities of your equipment. In advance of this and other extreme cold weather events, it is important to make sure your building is prepared.
We recommend taking the following steps to ready your building for the extreme cold, especially if you have made changes to how your ventilation system is operating since last winter, or you have new equipment:
  • Turn off all non-critical exhaust systems (i.e. residential kitchen and toilet exhaust)
  • Temporarily reduce ventilation where possible
    • DO NOT turn off 100% Makeup Air Units (MAUs)
    • If 100% MAUs shut down unexpectedly and cannot be restored, we advise shut down of the toilet, kitchen and similar exhaust systems
  • Override unoccupied and overnight setbacks to occupied
  • Avoid scheduled shutdowns of systems
  • Avoid turning heating related equipment off
  • Verify all coil pumps are operational
    • DO NOT shut coil pumps off
  • Maintain continuous operation of all heating related pumps
  • Minimize infiltration
    • Keep doors, windows and other openings sealed
    • Add temporary heat where infiltration can’t be controlled
  • Keep blinds and shades closed on windows at night and those not receiving direct sunlight during the day
  • Perform a system check of all heating critical equipment
  • Verify the operation of all low-limit safeties such as freezestats to protect equipment
    • Ensure the sequence of operation is followed upon a freezestat trip (Example: outside air dampers properly shut and can be reopened)
  • Verify the operation of all backup or redundant heating equipment not normally used
  • Verify the location of isolation valves, verify their operation and understand when to use them
    • During an emergency situation where a pipe, coil or other system has frozen, the reliability, and proper use of isolation valves is critical
    • Isolate the leak to as local an area as possible.
    • Take care not to close the wrong valve (essentially stopping the flow of water)
      • Water at rest is much more likely to freeze. Therefore, do not risk further freezing of the system by closing the wrong valve, should isolation be required

NFPA Driven Sprinkler System Antifreeze Replacement Required by September 30, 2022

The Problem

Fire protection systems typically use an antifreeze that is manufactured with propylene glycol or glycerin, both of which are flammable. In some cases, previously permissible concentrations of antifreeze in fire protection systems have been proven to have exacerbated fires and even resulted in explosions when antifreeze solution has come into contact with the flames that initially triggered the system.

To address the above concern, the National Fire Protection Association (NFPA) established requirements in 2014 regarding the chemical makeup of acceptable antifreeze solutions, the allowable concentration of antifreeze in systems, and the size of systems that uses antifreeze. Included in the 2014 changes to NFPA 13 and NFPA 25 were maintenance requirements for existing antifreeze sprinkler systems. These maintenance requirements include:

  • Annual testing of the system
  • Installation of an additional control or test valve, if needed
  • Installation of signage explaining the locations of antifreeze in the facility, the antifreeze supplier, and the concentration and volume of antifreeze in the system.

What’s Now Required

All existing antifreeze sprinkler systems must be brought up to current NFPA requirements no later than September 30, 2022. If a building utilizes an existing antifreeze sprinkler system that was installed before 2012, NFPA 13 and NFPA 25 require that the system either be modified to utilize an acceptable antifreeze solution (described below) or converted to a fire protection system that does not require antifreeze.

The Solution: Modification Process and Antifreeze Replacement Options

To replace an existing antifreeze solution, the following process should be followed:

  • Flush the System. The fire suppression system must be flushed to eliminate any traces of the antifreeze solution.
  • Replace the Antifreeze. Once the sprinkler system has been properly flushed, the antifreeze solution must be replaced with a UL listed, noncombustible, solution.

Currently, only two antifreeze replacement solutions are available on the market that meet NFPA requirements for new fire protection systems or retrofit of existing fire protection systems:

  • Viking FreezemasterTM
  • Tyco LFP Antifreeze+TM

Both of the above products have passed stringent corrosion tests and are identified as safe for use in cold-weather antifreeze sprinkler systems. Retrofit of an existing sprinkler system with the above identified products requires modifications to the existing sprinkler systems to ensure proper functionality.

How We Can Help

For buildings containing antifreeze sprinkler systems, Elara’s Fire Protection Design Team is ready to assist building owners and managers in navigating the decision-making process and implementing system modifications. Specifically, Elara’s experts can:

  • Confirm where antifreeze systems are permitted.
  • Evaluate existing antifreeze systems to identify options for modification to meet NFPA requirements.
  • Specify a retrofit for existing fire protection systems to use a listed antifreeze product.
  • Design a new compressed air or nitrogen dry system that will not require antifreeze to protect areas subject to freezing temperatures.

For more information about the required sprinkler system modifications and the upcoming September 30, 2022 deadline, please contact us at info@elaraeng.com.

Long Lead Times for MEP Equipment Require Project Planning Up to One Year in Advance

The New Normal – A Longer Planning Timeline

Simply put, if a building representative believes they need a new chiller, boiler, or other mechanical, electrical, or plumbing (MEP) equipment by the Summer of 2023, they likely should be planning to have their project in design during the Summer of 2022.

Elara Engineering’s design teams are tracking MEP equipment delivery lead times as long as 16-20 weeks, with certain situations extending beyond this duration.  This includes major equipment such as air handling units, chillers, and boilers as well as major components (larger sized valves, pipe fittings, etc.) which are impacting both retrofit and repair projects.  Due to the long equipment lead times, clients may not realize that advanced planning is necessary to ensure their project is completed on time.

 

What is Elara doing to assist Clients during the preliminary phases of the Project Development?

  • As soon our MEP design teams become aware of a client’s interest in undertaking a project – before we’re even retained or formally asked for a proposal; we make inquiries with major equipment manufacturers regarding general lead times and integrate this information into the projects and timelines we propose.
  • We then advise our potential client about when approval to proceed is needed – particularly if the project is driven by a seasonal need (e.g., winter heating, summer cooling, etc.).
  • As part of our engineering proposals, we also identify and incorporate tactics to preorder long lead equipment, if required, to ensure that the project schedule can be achieved.  Proposals may even include a preliminary schedule so that stakeholders know what to expect and when key decisions should be made.

 

What is Elara doing to assist Clients during the Engineering Design Phase?

  • As we evaluate multiple equipment manufacturers on key attributes like energy efficiency, physical size, etc., we also consider equipment delivery lead times as part of the overall selection process.
  • We identify and evaluate phasing opportunities to minimize the risk that the building is without the service of the equipment being replaced. For example, if multiple boilers/chillers are planned for replacement, we evaluate a sequenced construction approach so that only one unit is replaced at a time to ensure that existing equipment can continue to support the building until all new boilers/chillers are operational.  We also evaluate if the new equipment can be installed at a different location (e.g., adjacent to existing equipment) so that downtime is further reduced.

 

Additional Thoughts

  • Even with the efforts described above to address current market conditions, delivery times can be further delayed. Therefore, it is important to plan ahead as much as possible and to be conservative when establishing project schedules as actual equipment delivery dates are ultimately beyond full control of the client, contractor, and design engineer.
  • When purchased equipment is a major component of a new or retrofitted MEP system – like an air-handling unit , boiler, chiller, or switchboard – and if delivery of that equipment is delayed, the building’s owner, manager, and occupants can be negatively impacted due to a lack of service when needed and when required to meet local ordinances. As a result, we recommend that clients contact us as soon as they are considering an MEP project so that, together, we can begin evaluating equipment lead times and planning the project schedule.

 

For more information about equipment lead times and planning for your future project, we urge you to contact us at info@elaraeng.com.

Elara Completes Wintrust Sports Complex At Bedford Park Project

Wintrust Sports Complex at Bedford Park – a multi-purpose sports tourism and local programming facility – recently opened its doors after completing construction in September 2021. The 2-story, 111,000 square foot venue houses 8 high school hardwood basketball courts (or 16 NCAA volleyball courts), one championship court, a Redemption Arcade, Laser Tag/Laser Frenzy, an e-Sports Café, flexible meeting and event space, a café with full kitchen service and lounge, and offices.

 

Working in collaboration with ALPA Construction, Elara Engineering’s services for the project included Schematic Design, Design Development, Permit/Bid/Construction Documents, Bidding, Construction Services, and Functional Testing.

 

Creative Solutions

A key challenge for this project was the need to address the many, highly diverse uses of the building which included individual offices, café/lounge space, recreational areas (e-Café, laser tag), flexible event spaces, and a large, high-ceiling sports facility (gymnasium). As the project’s MEPFP engineer responsible for the design of MEPFP equipment and infrastructure for the newly constructed facility, Elara’s design team – beyond addressing the overall MEPFP design challenges posed by the diverse uses of the facility – successfully incorporated the following sustainable project features:

  • Outdoor air CO2 control, saving energy by tracking CO2 levels within the occupied spaces.
  • Energy recovery enthalpy wheels to recapture energy from the discharge air stream to pre heat or pre cool the mixed air.
  • Variable speed compressors for rooftop units operate efficiently based on space load.
  • Fabric ductwork distribution system within the gymnasium.
  • State-of-the-Art web-based, open protocol building automation system.
  • Lighting control that includes occupancy sensors and automatic daylight harvesting.

Additional design elements include:

  • Gas-fired packaged rooftop units that are either single-zone VAV or VAV for individual room control to effectively serve all areas and functional uses of the building.
  • VAV systems are a combination of perimeter fan powered and interior single-zone VAV boxes with electric reheat.
  • Bathrooms are exhausted with variable flow toilet exhaust, including automatic Control dampers.
  • Natural gas generator for life safety, elevator, and fire pump.
  • Event power distribution system.

K-12 Schools Pursue Projects to Improve IAQ/Ventilation

As K-12 school leaders, officials, and stakeholders have kicked off what they hope will be a more typical academic year for 2021-2022, they also recognize that COVID-19 cases are still present in their communities and that this virus, or any other airborne pathogen, can negatively impact student and instructor educational spaces.  As a result, and because of the potential to access new Federal and/or State funding opportunities (e.g., CARES Act), Elara Engineering’s K-12 MEPFP Design Team has seen increased interest in strategies and projects to improve ventilation systems and Indoor Air Quality within K-12 educational facilities.

CARES Act Funding Resources

To address questions about funding opportunities through the CARES Act, the U.S. Department of Education’s Office of Elementary and Secondary Education has issued the following FAQ document regarding Elementary and Secondary Emergency Relief (ESSER) Programs and the Governor’s Emergency Education Relief (GEER) Fund.

Included in this FAQ document are the following two questions:

B-6. May ESSER and GEER funds be used for construction?  The short answer is Yes; but qualifiers, restrictions, requirements, and timing constraints that may be applicable at the State level are also described in the FAQ document.

B-7. May ESSER and GEER funds be used for renovation, including for such projects as making improvements to a school facility to improve indoor air quality (such as heating, ventilation, and air conditioning (HVAC) systems), and projects that would promote social distancing and safe in-person instruction? Again, the short answer is Yes; but qualifiers, restrictions, requirements, and timing constraints that may be applicable at the State level are also described in the FAQ document.

Elara’s Expertise

While some School Districts are electing to utilize their CARES Act funds for short-duration, smaller scale IAQ and ventilation system upgrade projects, others are electing to allocate their funds towards additions and major renovations to reduce the density of students in classrooms. Elara Engineering has seen a large increase in the number of projects being considered and implemented.  Specifically, Elara’s K-12 MEPFP Design Team has collaborated with several School Districts in preliminary planning for IAQ/ventilation projects that are now being designed for bid this Fall/Winter for Summer 2022 construction.

More information about our previous and ongoing K-12 projects can be found on our website here.

Elara Successfully Completes 2021 Summer Internship Program

While still adhering to ongoing social distancing, handwashing, and mask-wearing practices, a slowdown in the number of Chicago-area COVID-19 cases during the summer months gave Elara Engineering the opportunity to continue its invaluable 2021 Summer Internship Program and allow for a hybrid format (in-person and virtual).

This year’s three talented summer interns were assigned to market-focused teams and were quickly working alongside Elara engineers on a variety of multidisciplinary projects. As active members of Elara technical design teams, the interns performed field surveys to document existing conditions, utilized AutoCAD (2D) and REVIT (3D) drafting/modeling software to support the preparation of engineering drawings, executed basic engineering calculations, and toured one of Elara Engineering’s active construction sites. Additionally, Elara’s Intern Training Program included weekly presentations conducted by Elara Principals, Team Leaders, and Project Engineers covering a wide variety of topics, including MEPFP technical presentations, HVAC 101, Plumbing Jeopardy, History of Elara, numerous project presentations, and a panel discussion conducted by previous Elara Interns who are now full-time Elara employees.

My experience with the Elara internship program was one of immense learning. Not only was I able to expand my skills in drafting software, but I was also able to create a deeper understanding of my work through several site visits. As the summer went on, I felt a lot of satisfaction in using floor plans that I had drawn to survey job sites – knowing a lot more at that point than I had when the internship began. Every engineer I worked with this summer provided a unique look into the HVAC industry, which helped me to envision future career possibilities.

Elara’s summer internship program allowed me to meet people who cared about helping me learn the industry and who made me feel right at home from the very first day. My favorite part of the internship was the site visits, where I was able to see how my work on CAD would impact the overall project. The internship program was an enjoyable and enriching addition to my school studies.

I learned so much at Elara this summer and worked with many amazing engineers. Maine East High School was the main project I worked on and my favorite. I was able to go on site and see the things we were working on, as well as what had already been done during the previous summers. It was interesting being able to work on this project alongside some of the smaller projects. My Revit and AutoCAD skills and efficiency improved throughout the summer, working on many different projects in each. Overall I learned a lot of new things and enjoyed my experience at Elara this summer.
