Crowd oil—fuels from air-conditioning systems

Researchers at the Karlsruhe Institute of Technology (KIT) and the University of Toronto have proposed a method enabling air conditioning and ventilation systems to produce synthetic fuels from carbon dioxide (CO2) and water ...

Aquifers for environmentally compatible cooling and heating

In this year's record summer, everybody wishes to have a cooled home or office. But air conditioning systems consume a lot of energy and are far from being environmentally compatible. Researchers of the GeoSpeicher.bw project ...

Designing urban energy systems based on the urban climate

As cities grow at an ever-faster pace, concerns about global warming rise and fossil fuels become increasingly scarce, cities will have to adopt more sustainable energy solutions. EPFL researchers have developed a model that ...

Smart buildings: energy efficiency at what price?

Automating heating and other environmental controls can bring huge savings to commercial buildings. To what extent is it possible to achieve the same results in residential homes? What is the difference between so called ...

Ceiling panel cools regardless of climate

Poorly maintained air conditioning systems cause mold or other bacteria to spread; they often also generate drafts and are costly to operate. An alternative technology that uses ceiling panels covered in special heat-conducting ...
