Preliminary Technology Assessment
What is This Technology?
Smart windows can dynamically change light transmission, transparency, and solar heat gain factor. This project compares two smart window technologies - electrochromic windows, which have varied tinting values between 2% and 60% via electronic controls, and a thermotropic organic polymer "window filler" that darkens as surface temperature increases. These are the first federal building installations of this technology.
Why is GSA Interested?
Measurement & Verification
The Green Proving Ground program has commissioned the Lawrence Berkeley National Laboratory to perform measurement and verification (M&V) on “smart window” technologies at the Denver Federal Center in Denver, Colorado.
