Energy efficiency is all about eliminating waste and maximizing the return on dollars spent for energy. It involves design, construction methods, efficient materials and quality systems that use less energy. An energy efficient home is a result of the way the home is built as much as it is a result of the products you put into it. So, for the best, most efficient home, it’s necessary to start from scratch and build the home properly from the ground up. There are several things to incorporate when building an energy efficient home: The home’s exterior (including walls, windows, doors, and insulation) should not allow heat or cold in or out. Heating and cooling systems should be high efficiency systems delivering maximum value for the energy used Solar, wind and other natural resources should be used where possible High quality and efficient appliances & light fixtures can reduce the amount of energy needed for them to operate. Energy efficiency is not only the conscientious thing to do but it saves money in the long run. It may cost a bit more up front, but your returns will come over years with lower energy bills.
