Grounded Energy Efficiency

摘要

What is the bigpst thermal mass in the world? The world, of course! Ground source heat pumps (GSHP) are a way of extracting stored solar thermal energy from the earth. Throughout Nevada, we have ground source resources from both stored solar energy and active geothermal sources (similar to geysers.) The best way for typical development projects to make use of geothermal resources is to make use of the relatively constant temperatures found just below the surface of the earth for building heating and cooling. The principle is a simple heat exchange; when your building gets hot, let the ground absorb the heat. Similarly, when your building gets cold, let the earth warm it up. Throughout Nevada, the deep-earth temperatures (without geysers and such) range from about 55 degrees in the north to 75-80 degrees in the south.
