Four Seasons Energy Efficient Roofing, Inc. (FSEER) installed 50,000 square feet of Duro-Last's single ply PVC roofing system on the Merrick, Inc. building in Vadnais Heights, Minnesota. The project is the largest solar electric application in the state, with 525 solar panels installed that are expected to produce 130,000 kilowatts of electricity a year.

The white membrane was perfect for this sustainable project because it is solar-ready. It also acts as a waterproof barrier for green/vegetative/solar roofs and is durable, long-lasting, custom-made, easy to install, leak-proof, and energy-efficient. It's the highest Energy-Star rated roof with 86% reflectivity even after three years.

The solar roofing assembly complements the buildings many other sustainable building features. Among them: a geothermal energy system under the parking lot, powered by the rooftop solar panels, will provide both heating and cooling; every room will have occupancy sensors to control electrical usage; the building will have energy-efficient insulation and windows throughout, maximizing natural light.
