Energy Efficient Color Options For Pre-Engineered Steel Buildings

We are trying to find ways to save and protect the environment and reduce their carbon footprint, however finding a cost-efficient way to do so is not always easy. The availability of  “cool paints” provide customers with an energy efficient choice for their pre-engineered steel buildings and prefab metal buildings without sacrificing the look of the building. 

“Cool” paint coatings are formulated with solar reflective pigments that work to reflect infrared radiation. This means that less solar energy is transferred to the interior of a structure as heat when compared to standard metal roofing coatings or traditional asphalt shingles.  Their superior reflective qualities such as “cool” paint coatings act as a thermal barrier to keep the inside of buildings cooler. This “cool” coating  protects the environment but also puts money back in customer’s pocket by providing huge savings on energy bills.

Energy costs for cooling can be reduced by up to 20% and peak cooling demand by up to 15 percent. These savings are realized through the pigmentation in the paint coatings that work to increase the amount of solar energy that is reflected off the roof. Less heat buildup in a structure requires less energy for cooling and works to reduce cooling costs. Studies conducted by various federal agencies and independent organizations conclude that a cool metal roof can reduce the energy costs associated with cooling the interior of a building by up to 20% and reduce peak cooling demand by up to 15 percent.

With “cool” paints, the paint formula is optimized to achieve higher solar reflectance. The higher the solar reflectance value of a material, the more solar energy that is reflected from it. Traditional asphalt shingle roofs have a solar reflectance of around 10-20%, whereas cool metal roofs have a solar reflectance of up to 70%. This means that a cool metal roof could reflect up to 70% of the sun’s energy away from the surface, with only 30% being absorbed. Shingles, on the other hand, will absorb 80-90% of the sun’s energy. The high solar reflectance of a cool metal roof translates into less heat transfer to the interior of a building, and less energy used for air conditioning and other cooling methods.

So, if you want to save energy and money, consider energy efficient colour options for your pre-engineered steel building.
