Project Summary


Responsive sustainable shading system

Cooling as a process is one of the biggest energy consumers in the building sector globally. Air-shade addresses this problem by proposing a shading system that is sensitive to solar exposure and powered by air – with no need of any external energy source.

It can vary in scale, size, material, and form: the proposed device is therefore applicable to a broad variety of buildings, constructions, façades, roofs, windows, etc.

Search Help

Our website search engine covers the web pages including project descriptions and expert profiles, PDFs, images and videos on the Holcim Foundation website. To improve your search results, here are some tips:

Basic search

Our search defaults to term-pairing AND. If you search sustainable construction - then the search engine will look for any items containing sustainable AND construction


photovoltaic OR solar

Looks for either word


(clay OR mud) AND (school OR university)

Combine alternative terms for more specific searching


geothermal -heating

Excludes a term from results, automatically ANDs other terms listed


"zero carbon"

Use quotation marks to search for a specific phrase or combination

Wildcards (one or more characters)


Asterisk (*) matches any word or phrase - so archit* will find architect, architecture, architectural as well as architrave
