Project Profile: Franklin Energy, Port Washington, Wisconsin




Franklin Energy Services, LLC (Franklin Energy) has consulted with utilities and local governments across the U.S. to create energy efficiency programs for leading commercial, industrial, agricultural and residential customers since 1994. So it was especially flattering that Franklin Energy selected our Variable Refrigerant Flow (VRF) zoning system for its new headquarters.

Here’s the back story. In 2011, the company moved to an historic structure on the shores of Lake Michigan in Port Washington, Wisconsin to accommodate company growth. The building was an old processing plant in Port Washington’s historic district, which is listed on the National Register of Historic Places. Franklin Energy had three goals for the renovation:

  • Preserve the historic integrity of the building.
  • Continue the company’s long-standing tradition of making its headquarters a showcase of the firm’s dedication to energy efficiency.
  • Create a community atmosphere that emphasized occupant comfort.

Randy Mueller, Mueller Heating & Cooling, Saukville, Wisconsin, and Auer Steel & Heating Supply, a Milwaukee-based distributor, recommended our VRF zoning system for the job.

The historic building posed numerous energy challenges, including solar gain due to the building’s orientation and large glass windows. Our VRF zoning system helped Franklin Energy achieve electric energy usage of 12.2 kWh/ft2/yr and gas energy usage of 21.9 ft3/ft2/yr – 32 percent and 48 percent lower, respectively, than the Commercial Building Energy Consumption Survey (CBECS) average. The energy savings together with overall building comfort was a win-win for Franklin Energy.

“This Mitsubishi Electric VRF zoning system has been a lifesaver for individual comfort and for helping us save on energy costs,” said Paul Schueller, chief executive officer of Franklin Energy. “Because of the Mitsubishi Electric INVERTER® technology and individual room controls, the perimeter offices in this old building have been very comfortable in all seasons.”
