The document summarizes several emerging technologies used at the Center for Energy Efficient Design (CEED) including geothermal energy, photovoltaics, rainwater harvesting, green roofs, passive house construction, wind power, building orientation, and solar thermal systems. Geothermal energy uses the earth's natural heat for heating and cooling. Photovoltaic solar panels convert sunlight into electricity. Rainwater harvesting collects and stores rainwater from the roof and pavement for non-potable uses. A green roof has vegetation that provides insulation and habitat. Passive house construction creates an extremely efficient building envelope to minimize energy usage. Wind turbines generate electricity from wind. Building orientation maximizes daylighting and passive solar benefits. Solar thermal
