Recent advances in building technology and construction techniques have made it easy to integrate energy saving features into the design of homes. Retrofitting existing houses with energy saving features will pay for itself in the long run with the considerable savings on utility bills. Installing solar heating panels on the roof for heating water is one such simple step because water heaters often account for a chunk of a home’s electricity bills. Considering that 1.5 pounds of CO2 is emitted for every kilowatt hour of electricity produced, solar water heaters also contribute to reduced pollution.
Maintenance is the key to energy efficiency when it comes to appliances used in every home. Cleaning air filters in air conditioners, insulating hot water tanks and pipes are simple steps that reduce power consumption. Double glazing on windows is the best way to reduce heat loss and noise. In winter, ensuring good air sealing with caulking and weather stripping and controlled ventilation are all important to make sure that heating energy is not wasted. Heat recovery ventilators can remove the heat from exhaust air that is pumped out and transfer it to the fresh air entering the home using a heat exchanger device. Insulating cavity walls, floors and lofts may require more money but the investment will pay for itself several times over with the resultant energy savings. Replacing old worn out appliances like washers, dryers, freezers and boilers with newer Energy Star appliances that consume less energy is one of the common energy saving tips given.
