More than a surface
Building Envelope | Space | Performance
The building envelope is more than a surface.
It is the interface between architecture, environment and human space — mediating climate, light, energy, material, comfort and the relationship between inside and outside.
ENVLO approaches the envelope as an integrated architectural and environmental system, bringing together design, technical development and performance.
Designing better envelopes for a better built environment
Purpose
ENVLO seeks to develop building envelopes that use material intelligently, respond to climate, improve environmental performance and consider their impact throughout the building lifecycle.
