Project Objective

Demonstrate and perform field validation of the highly insulated windows, factory-installed in a pre-fabricated wall panels and brought to a building site as integral modular units, ready to be assembled into the full building envelope sections. The team will incorporate highly insulated window glazing, and dynamic shading configurations into window units that are fully installed and sealed in a factory and transported to a site as integral units.

Project Impact

Highly insulating dynamic windows have the technical potential for net zero energy performance, which translates to approximately 4 quads of energy savings per year. When these advanced windows are coupled with daylight harvesting technologies – such as the variable-width light-redirecting shade proposed in this project – the technical potential can reach 5 quads of savings, or over $50 billion per year in energy savings. With reduced envelope infiltration, those savings go even beyond 5 quads.
