Homeowners know that the type of windows in a house contribute greatly to heating and cooling efficiency. And that’s a big deal.

Researchers have developed a material that, when coated on a glass window panel, can effectively self-adapt to heat or cool rooms.

Terracotta tiles provide a natural, cost-effective way to reduce energy consumption for cooling down subway stations during the summer.

A simple cooling system driven by the capture of passive solar energy could provide low-cost food refrigeration and living space cooling.

A single tree along a city street or in a backyard can provide measurable cooling benefits according to a new study from American University
