BCI Contracting, Inc. is now offering “cool roofing” systems.
WHAT IS A COOL ROOF?
WHAT IS A COOL ROOF?
Simply put, a Cool Roof is a light-colored commercial roofing system that reflects the sun’s heat and damaging rays and readily emits any absorbed solar heat, thereby lowering the roof and building temperature and protecting the roof from sunlight degradation. The potential impact of installing a Cool Roofing System is impressive–-studies show reduced cooling energy demand in buildings by up to 50%. A Cool Roof commercial roofing system saves money, last longer with lower maintenance costs, help reduce power plant emissions, improve air quality, and cut landfill waste.
Approximately $40 billion is spent annually in the United States to cool buildings, one-sixth of all energy consumed annually. Black and dark-colored roofing materials can dramatically increase a building's cooling load. Energy-efficient roofing systems, also called "cool roofs", can reduce roof temperature by as much as 100°F during the summer, and thereby reduce the building's energy requirements for air conditioning. Cool roofs reflect the sun's radiant energy before it penetrates into the interior of the building. In fact, reflective materials also help keep the building's neighborhood cool.
Heat Island Effects
A cool roof not only benefits the building that it is installed on, but also the surrounding neighborhood. In the summer, major urban areas become heat islands, where temperatures can soar 4° to 8°F degrees above the temperature in the surrounding area. This rise in temperature corresponds to a rise in harmful ozone, and therefore smog levels in the urban air. For every degree above 70°F, the incidence of smog increases 3%. A city of buildings with reflective roofs will not experience this effect as strongly. A recent study by the Lawrence Berkeley National Laboratory (LBNL)'s Heat Island Group found that if the buildings in Los Angeles were upgraded with reflective roofs, the city could save $35 million per year in energy costs.
