Set Back Thermostats

Setting down thermostats has proven an effective way to reduce energy costs during the cooler seasons.  Building temperatures usually cool at night when the occupants are asleep and raise to normal levels when the occupants are active.  However, when the temperature drops at night and the corresponding increase in relative humidity occurs raising the possibility of mildew and mold growth on the cool surfaces.  You can reduce the possibility of indoor mold growth by raising the interior of the building temperature during heating periods.

Closed rooms and Closets

Many occupants of structures close off unused rooms or closets during the heating season.  This effectively reduces the air flow and temperature of structures on these areas.  The practice used to commonly reduce energy costs increases the possibility of mildew and mold growth.

Air Conditioned Spaces

Cooling a space can be as problematic as heating the same space in a the opposite climate.  The principal applies: either the surfaces that are too cold, or the places where moisture condenses can cause the potential for mold growth.  Cold spaces in a air conditioned  area can usually be found in front of the vents.  For example, hotels that use air conditioning in the warmer climates usually have a wall covering which traps the moisture between the gypsum board.                                                          

Windows

Windows are usually the coldest visible surface within a room and this can be the first area condensation can be seen on the window.  Condensation can occur because of increased humidity due to airborne moisture or a rapidly decreasing outdoor temperature.  If the amount of moisture condensing on the window is substantial       this may increase the ability for mildew and mold growth.                                                          

Several Solutions

1)  Try to control the amount of humid air entering the entering the structure.  Check all window and door seals.  Seal visible cracks observed on the structure; prevent humid air from entering the structure.2)  Eliminate the cold spots with in the structure or the air conditioned space.  3)  Increase the ambient temperature within the closed rooms and closets during the cooler seasons.  4) Decrease the amount of wall coverings (wall paper).
