Bringing Students and Teachers Back to the Classroom Safely SCHOOL DISTRICT IN COLORADO CHALLENGE Long before the coronavirus outbreak, a Colorado school district passed a bond allocating for system updates in its schools, including the replacement of HVAC equipment with like-for-like models. However, after experiencing the global pandemic in 2020, the district wanted to assess what was needed to make sure their new equipment would be up to the task of creating healthy environments for teachers and students returning to the schools. It was at this point that BranchPattern was engaged to help with the assessments.

SOLUTIONS By utilizing the Facility Infection Risk Estimator™, BranchPattern helped the district staff understand how viral particles are transmitted and the overall best practices to reduce the spread of viruses, like the COVID-19. As a result, the best strategy that worked for these buildings was to upgrade systems beyond like-for-like models, leading to increased filtration and ventilation. Where

applicable, MERV-8 filters were increased to MERV-13, bringing more outdoor air to the learning environments. The benefits of this plan included reduced viral transmission, improved cognitive function in students and productivity in teachers.

To do so meant allocating more bond money than originally planned. After many conversations, presentations, models, and case studies presented by BranchPattern, the District’s Board of Education decided that this was a necessary improvement to make for the health and wellbeing of their students and staff. For this particular district, creating environments with the lowest opportunity to spread viral infection was the biggest priority in deciding how to bring people back in the buildings.

BranchPattern is continuing to assess the school district’s energy use, health results, and occupant satisfaction as the district returns to full in-person learning.

Better Savings GOULD ACADEMY CHALLENGE Gould Academy needed to install LED lighting and implement necessary lighting controls and appropriate lumen adjustments.

SOLUTIONS CVAL conducted a detailed lighting and implementation of recommended energy conservation measures that reduced lighting energy use by 77%. The implementations were as follows: State-of-the-Art LED Lighting CVAL designed and installed a premium efficiency LED lighting system to comprehensively replace existing lamps and fixtures.

Lighting Control CVAL installed digital control system to reduce the operating hours of the lighting system through programmed scheduling and use of occupancy sensors.

The programming included automated dimming during daytime hours to maximize the use of natural light.

Lower Overhead Results in Quicker Payback DOUBLETREE BY HILTON HOTEL CHALLENGE As a result of aging, unreliable chillers, comfort complaints were on the rise at the Inefficient chiller operation was also resulting in high energy and repair costs, having a detrimental effect on customer satisfaction and the establishment’s bottom line.

SOLUTIONS DoubleTree contacted CVAL Innovations LLC, to help them address their equipment, and high energy and repair cost challenges. As the hotel’s energy services company (ESCO), CVAL Innovations did a comprehensive evaluation of the building to identify equipment and operational inefficiencies.

Conducting an energy audit The CVAL Innovations team conducted a detailed ASHRAE® Level 2 audit for the building and detailed load modeling using Trane® Trace® 700. As a result of this exercise, building load requirements were calculated, and various energy conservation measures (ECMs) were identified, including a variety of lighting and HVAC improvement options.

The decision was made to execute the project in two phases: a lighting retrofit followed by chiller and controls upgrade.

Evaluating chiller plant options After considering multiple manufacturers, CVAL Innovations selected Trane, a trusted HVAC partner, to evaluate the existing plant and suggest chiller options to meet energy

efficient design specs. Using the myPLV™ chiller performance evaluation tool, specific criteria, including the building’s location and purpose, were input and used to accurately predict efficiencies of the various configurations.

Payback periods, energy rebates, first cost, and 20-year life cycle comparisons were also calculated for each option.

Increasing efficiency Trane Adaptive Frequency™ drives work with the chiller motors to continuously match compressor speed to required levels, improving chiller efficiency at reduced loads. Using a building automation system (BAS), the hotel is able to maximize energy savings by optimizing the sequence of operations to the building utilization and weather conditions. Right-sizing the chilled water and condenser water pumps also helped with energy savings and reduced the leaks from chilled water pipes.

Reducing installation and maintenance costs Smaller in size, the Trane Optimus chillers fit through the outside double doors of the building, eliminating the need to tear down exterior walls for installation, saving time, materials and labor costs. The direct drive compressor design of the chillers reduces failure risk for improved reliability and lowers maintenance requirements. In addition, downsized chilled water pumps used in the new chiller plant have eliminated leaking, also helping to lower operating costs.
