WASHINGTON, DC—At the beginning of July 2015 new mandatory IECC and ASHRAE 90.1 standards for lighting switches and lighting fixtures were released.
The standard slipped into the market virtually unnoticed, which is surprising given the effect it could have on certain buildings and their tenants, says Robert Hartley, director of Research for Colliers International.
As he writes in a blog post and an alert on the subject:
“Under the new standards, if an improvement to a space requires 10% or more of the lighting fixtures to be changed, then all the fixtures within the space may need to be replaced. More importantly, three-lamp T8 fixtures are no longer acceptable. Therefore, more energy efficient fixtures are required to meet the new watts-per-square-foot requirements.”
The standard itself is very clear about what is required under what circumstances — and we will look more at that in a moment. [GlobeSt]
