as functional, comfortable homes.

On a more global scale, there is the ecological impact of our lives to consider. For every therm of heating saved, there's a bit less pollution in the atmosphere. For every propane tank, every bag of coal and every kilowatt of electricity you conserve by installing passive systems, the environment takes one less hit. The more people who install sustainable systems, the longer our non-renewable fuels will last and the better off everyone will be, living on a cleaner, healthier planet.

Whatever your reasons for researching passive heating and cooling systems, the advantages far outweigh the financial cost, especially when you consider that the initial outlay will be recouped over time.
