The Green Proving Ground program has commissioned Department of Energy National Laboratories to perform real-world measurement and verification of the following technologies in pilot installations in federally-owned buildings. Preliminary technology assessments are available below as PDFs.
Preliminary Technology Assessments
Electrochromic Windows with Dynamic Controls [PDF - 240 KB] In GPG’s ongoing exploration of EC windows, dynamic controls introduce the ability for auto-tinting windows to learn from occupancy patterns and individual preferences to improve user satisfaction and environmental quality. Findings available in 2017.
Electrochromic Windows [PDF - 215 KB] Electrochromic (EC) windows switch from a clear to dark state with a small applied voltage, and promise to optimize daylighting, visual comfort, and solar heat gains without the need for blinds. Window tinting can be controlled manually (using a button or switch), or by an automated building control system, which programs sensors to respond to changing sunlight levels and heat conditions. Findings available in 2017.
