The Air Barrier Association of America (ABBA), in conjunction with Oak Ridge National Laboratories (ORNL) and the National Institute of Science and Technology (NIST) have developed a web based energy saving calculator for building airtightness. This valuable new resource will help the building industry quantify energy savings based on the use of air barriers that increase the airtightness of buildings.

We all know that uncontrolled heat, air, and moisture transfer through a building envelope has a significant impact on energy usage. A comprehensive strategy for concurrently regulating these factors can have a major impact on reducing energy consumption. Air moisture barriers (AMBs) have proven to be effective and economic but now these benefits can be better calculated in advance.

The hope is that there will be wider adoption of air barrier systems in building design thanks to this simple and credible tool that can be employed by architects, designers, and owners to accurately estimate anticipated energy savings if an air barrier system is added to the design. This new energy saving calculator is based on the best science available, it’s easy to use, available to everyone, and best of all – it’s free.
