Completed in 2017, this four-story 154,000 sqft facility provides teaching and research space for Colorado State University’s biology department. Building features include research and teaching labs, faculty offices, classrooms, and study rooms. The ATS-provided building automation system supports control of the air handling units, heat recovery units, chilled water system, steam, and heating water system, zone boxes, and lab exhaust system
Energy Management Goals
Aurora Public Schools (APS) has served students from Aurora, CO for over 120 years. APS currently has over 40,000 students enrolled in 63 different schools. Managing energy use in a district that size is no simple task. In 2014, the District’s Maintenance and Operations team started an initiative to focus on saving energy at schools. The District also joined the U.S. Dept. of Energy’s Better Buildings Challenge with the goal of reducing energy use by 20% over a 10-year period ending in 2023. Although the District has been reducing energy usage, Craig Wright, Natural and Renewable Resource Manager for APS, knew the team would have to step up their efforts to achieve their full 20% reduction goal.
What is an Energy Information System?
An EIS provides facilities a tool to visualize energy usage and identify energy wasting activities. An EIS typically includes facility benchmarking, equipment fault detection, metering, and automated optimization tools.
Energy Information Systems & ATS Rocky Mountain
To achieve APS’ energy efficiency goals, Wright began discussing implementing an Energy Information System (EIS) with the local utility, Xcel Energy. The utility developed an incentive program that provides consultative services to identify energy saving actions and covers up to 30% of the cost of an EIS installation. Working with the utility, the District issued an RFP to install an EIS. ATS Rocky Mountain was ultimately chosen to install the system due to their experience with HVAC controls at APS, as well as their expertise in EIS and facility analytics.
APS utilizes various manufacturer’s control products throughout their schools, therefore they needed an EIS vendor that could integrate into any of the different systems. ATS previously upgraded APS’ building automation system (BAS) to Tridium Niagara N4. This allowed point data from any of the schools to be collected regardless of controls type.
ATS provided the District with a meter infrastructure for electric, gas and water utilities, along with an EIS implementation across three high schools and a technical college — covering a total of 951,309 sqft. ATS utilized SkySpark by SkyFoundry for the EIS and integrated it with the existing BAS. Working with Xcel Energy’s consultant, MichaelsEnergy, ATS programmed analytic rules to highlight energy wasting equipment and sequences, as well as an electrical usage model that allows the consultant to visualize predicted energy usage against actual use, allowing further fine tuning of the schools’ energy using equipment and earning APS more rebates in the process.

Operational Changes & EIS Expansion
The EIS implementation changed the way APS maintenance and operations staff interact. Wright is now utilizing the EIS regularly and holding weekly meetings with staff to prioritize work orders. This was a process that didn’t exist before and has been a learning experience for the staff as they see how their facilities can perform. Now work can be prioritized in regard to its impact on energy usage. Each school tracks open issues in a “First to Fix” report that is generated in the EIS. In the near future the District plans to extend their EIS platform into 9 additional schools. Not only is APS on their way to achieving their 20% energy reduction goal, they were able to implement the needed EIS while offsetting the installation cost using Xcel Energy’s incentive program. As of 2019, APS has reached a 12% reduction in energy usage at the District and expects to achieve the additional 8% savings by utilizing and expanding upon their EIS system.

Quist Middle School located in Thornton, CO will be the new home of 825 sixth, seventh and eighth graders when it is completed in 2020. ATS Rocky Mountain has been selected to provide a complete Alerton Compass building automation system for the new school named for long-time 27J Schools principal Roger Quist.
This project continues ATS Rocky Mountain’s legacy of providing 27J Schools with high quality controls installation, programming and support.
Completed in 2017 the CSU Canvas Stadium in Fort Collins brought college football back to the Colorado State University campus for the first time since 1967. Prior to the stadium opening, the CSU Rams played their games at Hughes Stadium across town. The 727,000 sqft facility features a 41,000-capacity stadium, training facilities, offices, an alumni center and 60,000 sqft of general classroom space.
ATS Rocky Mountain provided an Alerton Compass building management system for the facility along with control of the VAVs, VFDs and the central plant. This project had an accelerated time table that required ATS to integrate the stadium’s controls into the main campus front-end before the first home game of the season which was held soon after construction was completed.
The new 91,110 square foot, two‐story high school includes 22 classrooms, an auditorium, two gymnasiums, and locker rooms. ATS provided an Alerton building management system for the LEED Gold facility. This project consisted of temperature and CO2 control/monitoring for nine rooftop units and 60 classroom/offices. The Salida R-32-J School district will utilize this centralized campus building automation system to retrofit the other existing pneumatically controlled schools in their district to electronic DDC controls.
