Radiant barriers are utilized to reduce summer heat gain in attics and help to improve the efficiency of green building envelopes. A radiant barrier can lower heat transfer from attics to the building below, keep the attic space cooler and lower cooling costs by up to 17% in warmer climates. We take a look at how radiant barriers work, the different types of radiant barriers and some of the misconceptions surrounding them.
An effective building envelope is a combination of insulating building materials and a reduction in air leakage. This reduction can be achieved by using taller wall sheathing panels and through effectively sealing air leaks. When determining which air leaks construction professionals should focus on, Dave Wolf from Owens Corning Science and Technology has conducted a study to see which leaks require the least effort and sealant and provide the highest returns in building envelope efficiency.
An energy audit is a series of tests run to determine the efficiency with which your building utilizes energy. Whether you are planning a renovation to reduce energy consumption, or have just completed a new build, energy audits establish the efficiency level of your building envelope. Energy audits help to show where you can get the most savings for your building buck and what improvements will give you the best return on investment.
