Project Summary

Cooling Roof in California

Prototype for an evaporative roof for radiant cooling

This project is a research investigation on how to cool large-scale structures using water on the roof as a thermal insulator and solar reflector, including a prototype in Cherry Valley in California, USA.

The study culminates in a design of a big box structure that is as reduced in its formal manifestation as it is beautiful in its aesthetic simplicity.

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
