Tozour Energy Systems, a full-service heating, ventilation and air conditioning (HVAC) and building automation provider based in King of Prussia, has presented Liberty Property Trust with the Trane “Energy Efficiency Leader Award.”

Liberty, an $8 billion real estate investment firm headquartered in Malvern, has been committed to energy reduction, operational efficiency, and sustainable design and development for their southeast Pennsylvania real estate portfolio.

Since 2008, Liberty has reduced the energy consumption of their portfolio by more than 15 percent. The company expects recent HVAC upgrades, completed in 2013, will save Liberty an additional $185,420 in annual energy savings.

Twenty-eight of the 43 buildings owned by Liberty have earned the U.S. Environmental Protection Agency’s (EPA) ENERGY STAR certification since 2008. ENERGY STAR certification signifies that the building performs in the top 25 percent of similar facilities nationwide for energy efficiency and meets strict energy efficiency performance levels set by the EPA.

Commercial buildings that earn EPA’s ENERGY STAR certification use an average of 35 percent less energy than typical buildings and also release 35 percent less carbon dioxide into the atmosphere.

Tozour Energy Systems is a sales agent of Trane, a leading global provider of indoor comfort solutions and services.
