High-Performance Building Envelopes

Detailed overview of innovation with sample startups and prominent university research


What it is

High-performance building envelopes are building exteriors designed to minimize energy consumption and maximize occupant comfort. These envelopes incorporate advanced materials, construction techniques, and design principles to optimize thermal performance, reduce air leakage, and control moisture, resulting in buildings that are more energy-efficient, durable, and sustainable.

Impact on climate action

High-Performance Building Envelopes under Energy-Efficient Buildings elevate climate action by enhancing insulation and reducing energy consumption. By minimizing heat transfer and air leakage, these envelopes lower heating and cooling demands, curbing carbon emissions from energy generation, and fostering the development of sustainable, low-carbon buildings for a greener future.
