How Much Does Energy Star Roof Save

Researches found a 45 percent decrease in the flow of heat with the metal roof mostly attributable to the ventilation above the sheathing.

How much does energy star roof save.

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. 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. Products with energy star certification deliver significant energy savings compared to their non certified counterparts. The roofing materials that have earned the energy star label have a high degree of solar reflectance which means that they reflect more of the sun s heat than other materials.

Attic temperatures can vary as much as 20 to 40 degrees f which in turn can reduce energy consumption by 20. The color shingles your clients choose can have significant effect on the temperature of the upper levels of the building. 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. A reflective roof can reduce peak cooling demand by 10 15.

Researchers also found up to 25 percent reduction in cooling costs. One way to estimate how much energy you would save by installing a cool roof is by using the cool roof calculator. Roof color and energy efficiency. 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.

Cool roofs can save money several ways including energy savings rebates and incentives hvac equipment downsizing and extended roof lifetime. The energy star energy efficiency criteria do not include a specification for roof insulation. Additional cool roof costs include specialized materials and labor. The color of the shingles you choose for your build can have a significant impact on the building s energy efficiency.

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. When the roof is nailed directly to the roof deck there is no air space below. This causes greater heat loss from the attic in the winter.
