Excess heat - reduction and management

Maintaining a comfortable indoor temperature level of your home is important for the health and comfort of you and your family.

Ventilation is one of the least expensive and most energy-efficient ways to cool a building and the people inside it. Ventilation works best when an appropriate number and combination of vents are used to avoid heat build-up in your home.

Air movement is the most important way to expel heat. Evaporation of perspiration is an effective way to cool people. It requires air movement and moderate to low humidity.

Air movement cools your home by carrying heat out of the house as warm air and replacing it with cooler external air. Moving air can also carry heat from cooling systems such as air conditioning ducts to reduce its heat lead and possibly reduce energy consumption.

Well-ventilated and insulated roof spaces form a buffer between your home and the hot outside air. It might also help reduce your use of air conditioning.
