Human comfort and productivity, along with energy savings, were primary goals with this complete LED commercial office space retrofit. Occupied by three collaborating philanthropic organizations, United Way of Whatcom County, Chuckanut Health Foundation (CHF) and Whatcom Community Foundation (WCF), this 100% human-centric lighting project exhibits beautiful color tunable fixtures throughout all spaces allowing the inhabitants full control over their lighting environment. 2020 LED provided the human-centric lighting design which included tunable (color adjusting) LED troffers and tunable LED task lamps for each desk.
