New legislation was proposed to Congress that could mean new jobs and energy savings nationwide. Senator Ben Cardin of Maryland and Senator Mike Crapo of Idaho co-sponsored the proposed bill. The proposed bill offers incentives over the next 2 years on commercial roofs that install cool roof systems and meet energy efficient standards. If [...]
Residential Solar News: 20 teams will be challenged this fall to design, build and operate solar powered houses in Washington D.C. for the Energy Solar Decathalon. The teams have worked on the houses for two years. It’s quite interesting how they design, build and test the building and then disassemble the whole building and transport it [...]
Did you know that, according to the US Department of Energy, 40% or more of a home’s energy loss is due to air leakage? In a typical three bedroom house, 25% of heat energy is lost through windows and doors, 35% through uninsulated walls, 25% through an uninsulated roof, and 15% through uninsulated floors. Spray [...]
R-value is measured under laboratory conditions, but in the real world there are other factors that determine how effective a particular type of insulation may or may not be. Conduction, convection, and radiation all affect heat loss, but R-value only measures the first one, conduction, which is when heat is lost through solid materials. Radiation [...]
The American Society of Heating, Refrigerating and Air-Conditioning Engineers states that thermal comfort is achieved when 80% of a building’s occupants are satisfied with the environmental conditions. While it is extremely challenging to satisfy everyone all the time, particularly when people have varying metabolisms and methods of dress, there are some things that can be [...]

Many people think of roofs when they think of spray foam, but you don’t need to have a flat or low-slope roof to take advantage of the money-saving benefits of spray foam. 25% of heat loss in a typical three bedroom home is through an uninsulated roof. If you have a typical attic, your attic [...]
Vented attics typically are designed to remove excess heat, reduce the potential for ice damming, and remove moisture from within the building envelope. Insulating your attic with spray foam can change this dynamic in your attic. Because the spray foam is applied to the bottom of the roof deck, rather than the floor of the [...]
Climate change is impacting your roof, and you may not even know it. While hardly predictable on a local level, broad climate change trends seem to mean dramatic changes in overall climate in specific regions, and this can mean changes for how you protect your roof. Read the article to see why.
