Zoned Air Conditioning

Air conditioning zoning thermostat

To understand the green advantages of zoned air conditioning, we have to first look at standard homes and the reasons why they are often uncomfortable due to unequal temperatures in different rooms. This is caused by some of the rooms being on a side of the home that receives more or less direct sunlight, having bigger or smaller windows, higher or lower ceilings, being more or less insulated, being on the 1st or 2nd floor or in the basement, occupied more or less frequently, or that contains heat or steam producing appliances or not.

A single thermostat, then located in only one of the rooms dictates how much hot or cold air must be forced through the system into each room equally. The result is that the temperature in each room will continue to be unequal to the others. And because the thermostat is usually installed in the living room, it will be comfortable while some of the other rooms will be hot and others cold.

With regards to energy consumption, one of the reasons why standard homes are so inefficient is because their air heating and cooling systems service all of the rooms of the home at the same time even when some need more, less or no servicing. That is as wasteful as opening all the faucets in the home every time a single faucet is opened.

Green homes overcome this problem with programmable thermostats, individual thermostat sensors and room air duct dampers that dictate which rooms get air, how much, when and for how long. This is called zoning.

The result is that individual rooms or parts of a home can be heated or cooled to specific temperature levels (and even humidity levels), or not at all, to provide programmed and designated comfort. Also, conditioning the air in guest or other unoccupied rooms can be eliminated until needed. For these reasons, the EPA and the Department of Energy have declared that a zoning system can reduce a home’s heating and cooling bill by between 30-40%.

Where can you see air conditioning zoning in action?

Air conditioning zoning can be seen in some of our green home models. If you would like us to direct you to our nearest model where you will be able to see, touch and feel this energy saving green technology, PLEASE REGISTER and we will respond to assist you.
