What is it about?
This study examines how switchable ETFE double-skin façades can improve daylighting and visual comfort in office building retrofits. Using advanced simulations, researchers found that these façades reduce glare, enhance light distribution, and improve energy efficiency compared to standard glass façades. The findings highlight ETFE as a promising solution for upgrading office buildings with more sustainable and comfortable lighting conditions.

Why is it important?
As cities struggle with aging office buildings and rising energy demands, finding smarter retrofit solutions is crucial. This study explores how switchable ETFE double-skin façades can enhance daylight control, reduce glare, and improve energy efficiency without the need for demolition. By upgrading existing structures instead of replacing them, it offers a more sustainable and cost-effective path to creating comfortable, well-lit workspaces while cutting energy use.
Perspectives
The good news is that with this technology, we don’t have to tear down old buildings just to rebuild more energy-efficient ones—maybe the smarter, more sustainable solution is to upgrade what we already have.
