Energy efficiency is not often a precipitating factor in the decision to replace aging windows. However, once user comfort, maintenance demands, and aesthetics conspire to make window replacement unavoidable, a window project offers the
opportunity to improve energy efficiency and reduce operating costs. Whether owners pay for these expenses themselves or pass them along to tenants, energy savings can be a compelling consideration when designing new windows.
New window systems must comply with the requirements of the local code governing that jurisdiction. Any code that has adopted the International Energy Conservation Code (IECC) as a foundation also, by extension, uses a rcs data version of American
, and Air-conditioning Engineers (ASHRAE) 90.1-2013, Energy Standard for Buildings Except Low-rise Residential Buildings, as a reference standard. However, IECC identifies its own path to compliance, and adopting municipalities often further modify those requirements to meet their own, local needs.
