“Improving energy efficiency is one of the most constructive and cost-effective ways to address the challenges of high energy prices, energy and independence, air pollution and global climate change,” the Environmental Protection Agency states on its website, and the organization is absolutely correct. The awareness of energy efficiency has increased in the U.S. and around the world. Oct. 2 was Energy Efficiency Day, which promotes the benefits of energy efficiency. More than 580 companies (including Hanson), organizations and local governments participated, and the U.S. Senate recognized the day with a resolution.
With this in mind, what better way to start a new year — and a new decade — than by taking steps to:
- Make sure your building equipment and systems operate efficiently
- Save money due to lower operating costs
- Create a healthier and more comfortable environment for your building occupants
- Upgrade and extend the life of your equipment and systems
Implementing retro-commissioning (RCx), which is also known as existing building commissioning (EBCx), will help you with all the above and more. It is a process that seeks to improve how building equipment and systems function together. It can often resolve problems that occurred during design, construction or the normal operation of the building, and it upgrades and extends the building’s operations and maintenance procedures and enhances overall performance of the building.
As stated in the 2019 ASHRAE HVAC Applications Handbook, “system performance normally degrades with use and time, at a rate depending on the quality of maintenance and operations and the number of hours of operations.” Various papers and reports state that because of the normal aging process, building performance will deteriorate at a rate of 4% to 8% per year. The ASHRAE handbook goes on to say that “EBCx has been shown to be a very cost-effective way to improve occupant comfort and productivity and optimize operations costs. Energy savings of 13-16% with a one- to four-year payback have been reported.”
RCx moves beyond energy audits and reviews a building’s operation to ensure all the systems work as required to meet the current facility requirements. Many utilities also offer RCx incentive programs that can help underwrite project costs and improve your return on investment.
We encourage you to take the same positive steps many of our customers have taken and embrace energy efficiency to improve your operations, reduce your operating costs and create a healthier and more comfortable environment for your occupants. After all, it’s a good way to start a decade!
