Researchers have found a simple trick that can reduce your need for an air conditioner by 80%.
The technique is called passive cooling and it helps to prevent heat from entering the building.
What is the trick to keep my house cool?
Last year, it was found that shading and natural ventilation were enough to keep temperatures low for three days. It was surprising to find out that air conditioning wasn’t necessary.
The findings from this report are important because it could influence building codes that would protect renters from any severe heat waves. This could look like mandates for safer operable windows, working shades, and/or specific building requirements.
The research also found that opening the windows at night and in the early morning made the biggest impact. This is because that is when the outside air is the coolest.
You can also keep cool by combining the use of a ceiling fan with your air conditioner to reduce cooling costs.
