Energy Codes

Since the cost of energy continues to spiral upward, builders and architects are forced to design more energy efficient buildings, residential and commercial while maintaining costs. By using ENERGY STAR®products more windows and skylights are available for us by the builders and architects to bring in more light and create better attractive building suitable for livable spaces while meeting local energy codes.

Recent guidelines have been written into the International Energy Conservation Code (IECC) that make it difficult for the construction industry to adhere too. These codes, in some cases, limit the area of windows and skylight that can be installed in a given building when lower quality fenestration products are selected. In order for construction permits to be granted the energy performance for a building “envelope”, also known as the U-factors of its components, is required to meet strict minimal values.

The use of ENERGY STAR® qualified products is a traditional way to meet efficiency requirements while designing illuminated, spacious buildings. ENERGY STAR® products meet the criteria set by the Department of Energy (DOE) and the Environmental Protection Agency (EPA) which is why most VELUX products are qualified in all 50 states as ENERGY STAR®. The National Fenestration Rating Council (NFRC) must qualify them by testing their heat gain, loss, and light transmittance in order to be certified.

Warmer climates have a greater potential for energy savings by using emerging control technologies in conjunction with effective lighting products such as VELUX skylights and VELUX SUN TUNNEL™ skylights.
