Challenge A public library was facing excessive energy costs. The library wanted to explore Energy Conservation Measures (ECMs) to reduce operating costs.

Solution
Perfection identified the problem—an inefficient HVAC system coupled with an underutilized control system. A new HVAC control system was installed and the HVAC system operation was modified.

Results
The library noticed substantial energy savings after installation. The work environment improved for library staff, and the building was more comfortable for visitors. The library saves more than $11,600 in utility expenditures annually. The project will pay for itself in 3.4 years.
