FAQ > General questions

• How does an EE system work?
  ASolar energy from the sun is absorbed by the earth. A buried pipe (loop) circulates a fluid (usually ethanol or methanol or other approved fluid) that absorbs this solar heat from the ground and conducts it into the building, where a compressor is used to transfer the heat into warm air (or warm water) and then distributed throughout the building. It is more efficient and environmentally superior to ‘transfer’ heat than to ‘create’ it through combustion.

• What are the environmental benefits of an EE system?
  ABy transferring solar energy from the ground into a building, there is reduced need for generation and transmission of electricity, or less need to drill and transport fossil fuels, with an accompanying reduction in the emission of pollutants at all stages. Data from governments in both Canada (Natural Resources Canada) and the United States (Environmental Protection Agency) indicate that EE systems are the most benign space conditioning technology on the market today in terms of environmental impact.
