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.
How much does energy star roof save.
The color shingles your clients choose can have significant effect on the temperature of the upper levels of the building.
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.
The color of the shingles you choose for your build can have a significant impact on the building s energy efficiency.
When the roof is nailed directly to the roof deck there is no air space below.
The energy star energy efficiency criteria do not include a specification for roof insulation.
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.
Roof color and energy efficiency.
Additional cool roof costs include specialized materials and labor.
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.
Products with energy star certification deliver significant energy savings compared to their non certified counterparts.
One way to estimate how much energy you would save by installing a cool roof is by using the cool roof calculator.
Cool roofs can save money several ways including energy savings rebates and incentives hvac equipment downsizing and extended roof lifetime.
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 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.
Researches found a 45 percent decrease in the flow of heat with the metal roof mostly attributable to the ventilation above the sheathing.
Energy star certified roof products reduce the amount of air conditioning needed in buildings and can reduce energy bills by up to 50 percent.
This causes greater heat loss from the attic in the winter.
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.
