ENERGY EFFICIENT ROOFING
Our company is a founding member of the Center for Environmental Innovation in Roofing, an industry forum for increasing awareness, development and use of environmentally responsible, high-performance roof systems. Count on us to provide a full range of energy efficient roofing options and services including cool, green, garden and solar roofs, along with daylighting skylights.
Over 90 percent of the roofs in the U.S. are dark in color with low-reflective surfaces. In summer months, traditional roofing materials reach temperatures as high as 190°F (88°C). Cool roof materials are highly reflective and can deliver a 20-to 70-percent energy savings annually. Jim Giese Commercial Roofing has installed millions of square feet of cool roofing products.
“Green” roof system technology continues to evolve, with current assemblies, design and construction techniques improving greatly in the past few years. When choosing a green roof, a number of factors must be considered including climate, geographical location and building design, to name a few. We can provide our customers with a full range of options and services.
With a solar roof, a collection device acts as substrate for absorbing the sun’s rays. Some solar-collection devices are installed above the roof system, while others can be installed directly to the roofing membrane. Jim Giese Commercial Roofing, working with licensed electrical contractors, can arrange for the installation of a variety of solar-roof systems.
Skylights are used to reduce energy consumption while adding visual comfort by increasing natural light. With proper skylight design there can be significant energy savings via passive solar energy for commercial applications. According to the U.S. Department of Energy, a commercial building can reduce total energy costs by as much as one-third using daylighting to supplant electric lighting during business hours.
Though the two are often confused, a roof garden is quite different froma green roof. A roof garden consists of a vegetative layer grown on a rooftop or in trays placed on top of the roof membrane. These plants reduce the amount of heat absorbed into the building, lowering energy consumption. In addition, roof gardens provide thermal-radiation resistance and reduce thermal radiation and rain runoff while providing an attractive outdoor living space.
