Washington, Jun 28 (PTI) Opening the windows at night and pulling down shades during the sunniest part of the afternoon can keep homes from becoming dangerously hot during extreme heat waves, according to a study conducted in the US.

Researchers from the University of Oregon in the US employed simulations using weather data from a 2021 severe heat wave especially in the Pacific Northwest.

They found that a combination of shading and natural ventillation kept apartment temperatures out of the danger zone during the entirety of the three-day event, even without air conditioning. It also reduced the load on air conditioning by up to 80 per cent.
