How Much Does Energy Star Roof Save

The most energy efficient roofing products have a high solar reflectance meaning that they reflect the sun s energy back into the environment rather than absorbing it.

How much does energy star roof save.

Products with energy star certification deliver significant energy savings compared to their non certified counterparts. Energy star certified roof products reduce the amount of air conditioning needed in buildings and can reduce energy bills by up to 50 percent. These materials can lower the surface temperature of a roof by as much as 50 f and can reduce peak demand on air conditioners by up to 15 percent. The color of the shingles you choose for your build can have a significant impact on the building s energy efficiency.

The color shingles your clients choose can have significant effect on the temperature of the upper levels of the building. A reflective roof can reduce peak cooling demand by 10 15. Researchers also found up to 25 percent reduction in cooling costs. Roof color and energy efficiency.

Additional cool roof costs include specialized materials and labor. For the individual building owner an energy star roof could reduce the cooling demand by 10 15 percent https www energystar gov index cfm c roof prods pr roof faqs. When the roof is nailed directly to the roof deck there is no air space below. Attic temperatures can vary as much as 20 to 40 degrees f which in turn can reduce energy consumption by 20.

Reflective roofs can reduce the temperature on the surface of the roof by as much as 30 percent which means that less heat gets into your home source. While roofs do not use energy by themselves certain types of roofing materials called cool roofs have reflective properties that can help reduce the heat that would otherwise be absorbed through the roof. One way to estimate how much energy you would save by installing a cool roof is by using the cool roof calculator. Energy star certified roof products can help reduce the amount of air conditioning needed in buildings and can reduce peak cooling demand by 10 15 percent.

For energy star certification energy saving shingles must reflect at least 65 percent of solar radiation if installed on a low sloped roof or 25 percent if installed on a steep sloped roof. The energy star energy efficiency criteria do not include a specification for roof insulation. Researches found a 45 percent decrease in the flow of heat with the metal roof mostly attributable to the ventilation above the sheathing.
