They produce a lot of heat and usually leak into the attic, creating a draw on conditioned air from the room and making the air conditioning unit work even harder to cool the home. Use as little carpet at possible. Carpets are like huge sinks that attract and harbor dirt, dust, mold, mildew, and other possible allergens. This is especially important if any family member has asthma or other respiratory problems. Choose light exterior colors, particularly for the roof.
Light colors reflect the sun s rays and help keep the home cooler.
Skylights let in too much heat into a room in our climate. Light tubes are smaller and the lighting is less direct. Indoor humidity should be between 25 and 60 percent for optimal health and comfort. Molds and dust mites thrive in high humidity areas and can cause serious health problems. Be sure to choose quiet fans so you'll really use them.
