The Battle Against Heat Gain: Keeping Cool in the Summer Heat As the summer heat rolls in, the battle against heat gain becomes a daily struggle. The scorching sun, rising temperatures, and stifling humidity can turn any home into a sauna if not properly managed.
What Is Heat Gain?
Heat gain is the transfer of energy from a warmer surface to a cooler one.
It is caused by sunlight, radiation, and air movement.
Heat gain can increase the temperature of an interior space.
Causes of Heat Gain
Windows
Unshaded windows allow direct sunlight to enter an interior space.
Heat from outside can transfer through single-pane windows.
Low-emissivity windows reduce the amount of heat that is transferred.
Insulation
Poorly insulated walls and ceilings allow heat to transfer through the building envelope.
Unsealed gaps and cracks can increase heat gain.
Radiant barriers can be used to reflect the sun's rays and reduce heat gain.
Appliances
Heat from cooking appliances and electronics can increase interior temperatures.
Heat is generated by lights and other electrical equipment.
Heating, ventilation, and air conditioning (HVAC) systems can increase heat gain.
Solutions for Reducing Heat Gain
Window Treatments
Window treatments such as curtains and blinds can be used to block direct sunlight.
Low-emissivity window films can be applied to windows to reduce heat transfer.
Reflective window coatings can be used to reduce the amount of heat that is absorbed.
Conclusion
Heat gain can be reduced by making sure windows and insulation are up to date.
Window treatments such as curtains and blinds can be used to reduce direct sunlight.
Low-emissivity window films and reflective window coatings can also be used to reduce heat gain.
