If, compared to other places you have lived, you find your house unusually cold, it could be due to the home’s orientation to winter’s warming sun – but usually this is a sign of a damp home. In a damp home, the energy from the sun, and/or from heating appliances is first used to dry the home, and then to heat the home. Often occupants will be so focused on keeping warm they will be unaware for the air quality impacts in such premises.
