Challenge

The unreliability of operating a 50-year-old HVAC system at Montgomery County Department of Health and Human Services (HHS), and cost of maintaining it, created the need for a renovation. The building owner wanted to upgrade the infrastructure in the 280,000-square-foot building but needed the energy savings to fund the project. HHS is the major tenant in the building and needed to maintain occupancy and comfort while all upgrades took place.

Solution

Tozour Energy Systems’ multilayered approach included new AERCO boilers in two boiler plants, an upgrade to the building automation system (BAS), a Trane R’newal chiller, a complete retrofit of pneumatic variable air volume (VAV) boxes, and indoor and outdoor LED lighting upgrades.

Result

Since the Montgomery County HHS completed its renovations, the building has significantly decreased energy consumption. The energy use intensity (EUI) for the building has decreased 37%, and the operating costs have dropped $50,000 annually.

“In addition to saving money, our goal was to create a more sustainable building,” said Frank Morris, Facility Director, Silverang Development. “Not only has Tozour helped us become more energy efficient, but the savings have more than paid for the project financing and have given our company a positive monthly cash flow.”

The upgrades also earned HHS a substantial five-figure energy rebate incentive.
