When multiple people occupy a home, frequently one person’s sensation of comfort is another’s sensation of uncomfortable cold or warmth. When two such occupants share the same room at the same time, they will arrive at solutions such as adjustment and compromise. However, contemporary heating and cooling systems also acknowledge that different temperatures may be called for in different rooms of a single home. Alternatively, different rooms may be exposed to different conditions and thus require more or less heating and cooling than others to achieve optimal climate conditions. The solution in these situations is zoning.
