Your House and Summer Heat Gain Part Two

Ceilings

Attic ventilation and insulation affect the amount of heat that is transferred from your attic through your ceiling and into your living space.

Make sure your attic is properly ventilated. Without proper ventilation, attic temperatures can reach 140-160 degrees. These high temperatures not only cause increased air conditioning costs, but also can reduce the life of your roofing material.

To have natural ventilation, your attic must have a balance of intake vents and exhaust vents. Intake vents should be positioned lower than exhaust vents to achieve maximum benefit. Power-operated attic fans are generally not a good idea since they typically use more energy than they save.

Insulation

Insulation provides a line of defense between attic temperatures and the comfort of your living space. The effectiveness of an insulation material is measured in R-values and typically, the higher the R-value, the more effective the material is at reducing the amount of heat transfer.
Maintain minimum insulation levels of R-19 for exterior walls (total wall system) and R-30 in your ceiling.

Walls and Doors

A light-colored exterior paint will help reflect the sun, absorbing less heat and keeping your home more comfortable.

Internal Heat Sources

Internal heat is the heat given off by appliance motors, cooking, laundry and even our bodies themselves.

Avoid activities that can add excessive heat to your home during the hottest part of the day. These can include operating your oven, running your clothes washer and dryer, and running your dishwasher.
