About

  Our world is currently facing an impending energy crisis due to our overuse of energy and overreliance on fossil fuels. As our stores of fossil fuels run low, China, India, and other countries around the world are modernizing and increasing their energy use, and the threat of human induced global climate change is increasing.

  Many homeowners, trying to save money on utility bills and do their part for the environment, look to cut down on energy use by weatherstripping or sealing their houses to reduce heat loss. This is a noble goal, but in some cases it can lead to serious consequences: while air leakage is a significant source of energy loss, it is also the means by which stale indoor air is exchanged with clean outdoor air. Remove too much of this natural ventilation, and you will increase the concentration of indoor pollutants in your home, possibly endangering the health of you and your family.

  Enter Greentrofit™. Given a simple input of house characteristics, we can give you an estimation of your current air exchange rate, as well as how it compares to national averages and established health standards. Considering retrofits? Greentrofit™ can estimate their payback time, efficiency, and effect on air quality in your home.
