Geothermal Earth Tubes

The Problem
A lot of energy is wasted in office buildings after hours to try to keep the temperature in the building at an optimum temperature especially just before workers enter in the morning. Using energy during the night is wasteful and cooling and heating units produce GHGs that are harmful to the climate.

Technology: Geothermal Earth Tubes
The technology takes advantage of the difference in temperature between the ground and air. In winter, the ground is typically warmer than the air and the opposite is true for the summer. Since these tubes are in contact with the ground, they acquire the same temperature. During a cold night, cold air is sucked into these tubes and it travels through the ground, it slowly absorbs heat from the tube and ground and finally, the tube delivers the air to the building and provides heat, as well as fresh air and circulation. This technology does require maintenance to remove dust accumulated from outside. Also, monitoring technology is needed to control temperature levels and flow.

Stakeholders
Residents and companies in areas where a constant need for heating or cooling is present. Manufacturers of sensors used, construction companies as well as concrete suppliers. Electricity provider who might see their revenues fall.

Next Steps
Market this new technology as futuristic and taking advantage of natural phenomenas that promote reduction of GHG emissions by humans. Promote use of earth tubes with construction companies to utilize time efficiency with installation process (These can easily be installed while construction in place).
