Existing Building Commissioning is a comprehensive study of existing HVAC, refrigeration, and lighting systems to find low and no cost improvements to save energy and money.


Ventilation Management During COVID-19

We know the world looks a little different right now, which has highlighted the importance of proper ventilation inside buildings, especially in schools to keep students and staff safe.

With over 20 years of experience in Minnesota schools, we are here to help schools explore the best options for safe building operation. We are currently working with several school districts and municipalities to:

  • Outline current knowledge and provide guidance on best practices, including Centers for Disease Control and Prevention, MN Department of Education guidelines and ASHRAE.
  • Review building mechanical systems and document current ventilation rates
  • Identify the limits of what the current air handling systems can achieve

Contact us if you think your school or district could benefit from these services.
 

Efficiency is every company’s lowest cost option for energy savings. Our engineers help clients take practical action to cut energy waste and improve equipment functionality while enhancing comfort. We also disseminate our findings to help inform best practices in energy efficiency and related fields.

Our team is with you during the entire process to help you identify the best opportunities, help implement your choices, and verify that your savings are realized.

We are positioned to take on projects for a wide variety of facilities, from traditional offices to manufacturing, healthcare, correctional, schools and colleges, sports arenas, and more


Existing Building Commissioning

This comprehensive and systematic process improves the operations of your building systems to ensure they meet occupant needs while minimizing energy use. Existing Building Commissioning (EBCx) provides healthy, comfortable and productive work environments by bringing ventilation and indoor air quality up to standards, solving persistent problems with building operation and training Operations and Management (O&M) staff to improve building performance.

Energy Efficient Operations

After a building has been commissioned, CEE’s Energy Efficient Operations program can maintain efficient HVAC operations for the long term. This program provides building operators with a customized step-by-step manual to check on how their equipment is operating. The manual also provides instructions to diagnose any issues that may arise. In addition, CEE engineers follow up with building operators throughout the year to answer questions and help troubleshoot. This service gives operators the tools they need to identify problems before they amount to huge energy waste. 
 

Performance Monitoring

CEE’s Performance Monitoring service combines interval data from utility meters and trend data from building automation systems to see how equipment operation directly affects energy use. Our engineers analyze this powerful information and develop strategies to reduce peak demand and energy consumption.
 

Performance Certification

CEE has experience with EnergyStar’s Portfolio Manager, which is an online tool that tracks energy use, water consumption, and greenhouse gas emissions. Our engineers gather the necessary information to determine the EnergyStar score for your building. If the score is 75 or higher and you would like recognition for your hard work, we’ll help you through the EnergyStar certification process.
 

Benchmarking

Benchmarking is the process of comparing the energy use of your building to similar buildings to determine how well your building performs. This comparison informs staff about how well they are operating the facility and whether they should take additional action to get their energy use in line with similar buildings. Our engineers have benchmarked buildings using Commercial Buildings Energy Consumption Survey (CBECS) data, Minnesota’s B3 Benchmarking website, and EnergyStar’s Portfolio Manager.
