Energy efficiency

Energy codes Home owners are increasingly sensitive to energy use (and costs), and are demanding more and more efficiency from the products they buy and endorse. The ever-growing “sustainable living” movement serves to reinforce this fact.

VELUX has been ahead of the curve, and intends to stay there. With more than 90% of our production ENERGY STAR® qualified in all United States climate zones, you can include our products confidently and proudly.

Energy Codes
The cost of energy continues its upward trend. There is more and more pressure on product's energy efficiency...while keeping costs down!

It is a challenge for the construction industry to understand and comply with the energy efficiency guidelines that have been written into the latest International Energy Conservation Code (IECC) and other state and local energy codes. In some cases, when lower quality fenestration products are selected, these codes limit the area of windows and skylights that can be installed in any given building.

The overall energy performance of the building "envelope", or the U-factors of its components, must meet strict minimal values in order for a construction permit to be granted.

One of the most straightforward ways to meet the energy codes is to use ENERGY STAR® qualified products. All VELUX Sun Tunnel skylight products are ENERGY STAR® qualified in all 50 states, which means that they meet strict energy efficiency standards set by the Department of Energy (DOE) and the Environmental Protection Agency (EPA). ENERGY STAR® fenestration products must have their U-factor and Solar Heat Gain Coefficient tested and certified by the National Fenestration Rating Council (NFRC) in order to qualify.

By using ENERGY STAR® products, you can use more windows and skylights, bring more daylight inside and create more attractive, livable spaces while still meeting the local energy codes economically.
