NYSERDA Daylighting Case Studies

TRC conducted on-site monitoring of light levels and energy consumption for three buildings in the Northeast, along with surveys of the occupants and facilities staff.

Project Location

Northeast Region

The buildings in the study were selected because they used innovative daylighting approaches such as automated window attachments, light redirecting blinds and skylight light wells with splayed reveals.

These case studies showcase a variety of daylighting designs suited to the climatic challenges of the northeast region.

  • Genzyme Building, Cambridge, MA - This case study evaluates the performance of a building that uses a double‐skin façade for thermal control, automated blinds and a central atrium for daylight and ventilation, and many other sustainable features.
  • NRG Systems, Hinesberg, VT - This case study focuses on the south‐facing office areas of the NRG System building, and describes how incoming sunlight and diffused daylight is managed by reflective window blinds, to create a comfortable and efficient workplace.
  • Stop & Shop, New Paltz, NY - This case study evaluates the performance of innovative skylights used to provide daylight illumination. The skylights are designed to capture sunlight more effectively than conventional skylights when the sun is low in the sky, at the beginning and end of the day.

The achieved savings from the daylighting technologies in the three buildings ranged from 4% to 45%. In all cases the innovative technologies were improving the daylight availability and distribution in the spaces. In all cases, occupants were very satisfied and highly approved of the innovative technologies used in their workplaces.
