This super-reflective coating keeps buildings cool so we don’t need as much AC

IMG_9186

Buildings are already being painted white to help keep them cool. As temperatures increase, this new addition to the paint could help lower our massive air conditioning energy use.

One of the ironies of climate change is that as heat waves become more common, people use more air conditioning–and those air conditioners help drive more climate change, and make things hotter. By the middle of the century, as more people around the world can afford air conditioners, the number of units could more than triple and end up using as much electricity as China uses today for its entire economy.

‘Melting’ Drywall Could Reduce The Need For Air Conditioning

Acrylic microcapsules are filled with a paraffin wax that can absorb heat from buildings.

Building materials that absorb heat during the day and release it at night, eliminating the need for air-conditioning in some climates, will soon be on the market in the United States. The North Carolina company National Gypsum is testing drywall sheets–the plaster panels that make up the walls in most new buildings–containing capsules that absorb heat to passively cool a building. The capsules, made by chemical giant BASF, can be incorporated into a range of construction materials and are already found in some products in Europe.

Deep-Sea Air Conditioning System To Cool Honolulu

Honolulu, Hawaii

Frigid seawater pumped in from the ocean’s depths will soon help cool more than half of the buildings in Honolulu’s downtown. Honolulu Seawater Air Conditioning LLC, which is undertaking the $240 million project, expects its technology to cut the Hawaiian city’s air conditioning electricity usage by up to 75 percent while slashing carbon emissions and the use of ozone-depleting refrigerants.

World’s First Underground Stadium

World’s First Underground Stadium 

 “Wall” Stadium nicknamed “The Laptop”

When the new “Wall” Stadium set to be built in Doha, Qatar is completed in 2010, it will be the first underground stadium ever constructed. Nicknamed “The Laptop” for obvious reasons, the stadium will have no traditional floodlights. Instead, the lights will be embedded into the architecture, which adds to the clean futuristic look. Apparently, the unique underground design will serve as a natural air conditioning system of sorts, which saves money that could have been spent on a traditional domed, temperature controlled facility.
