Energy efficient homes save money for the homeowner while they conserve the planet’s limited energy resources. Simple things like replacing worn insulation and using energy saving appliances can increase the efficiency of a home and reduce the home’s reliance on non-renewable fuels.
Heat Does Not Escape Through the Roof and Ceiling
Most energy efficient homes are designed to block the transfer of heat through the roof and ceiling. Ceiling and roof panels that are made from thick foam can be used instead of normal sheet rock to provide an extra layer of insulation. There is also a new technique in roof building that utilizes as little wood as possible. This creates more space to be filled by insulation, which blocks expensive energy loss during hot and cold seasons.
Windows and Doors are Properly Sealed
Energy efficient homes need to be airtight so that the indoor temperature can be closely controlled. Every crack and crevice is filled with caulk or sealed with a firm rubber seal. Double paned windows can also trap the outside air and keep it from having a serious impact on the temperature inside the house. Window and door seals are the easiest and least expensive way to make a home more energy efficient.
Equipped with Energy Saving Appliances and Lighting
Many appliance and lighting manufacturers have become aware of the benefits of using less energy to run their appliances. Home owners who choose large and small appliances that carry energy efficiency ratings will experience a dramatic difference in their energy bills. Energy efficient homes are also usually equipped with lighting that uses less energy. Energy saving light bulbs are available in every shape and size and tend to last years longer than normal light bulbs. Energy efficiency can be increased by installing light sensors and timers so that lights will automatically turn themselves off when no one is in the room.
Supplemental Solar Energy
Energy efficient homes that utilize some form of supplemental solar energy offer the most substantial energy savings for home owners. Solar panels are available in many different forms and sizes to fit the needs of almost any home. Most solar panels are connected to batteries that store energy when the sun is not shining. It only takes a small amount of sunlight each day to provide enough energy to fill a common solar battery. The initial installation of a solar unit is the most expensive part of the process. Once installed, the home’s energy efficiency can be increased by as much as half.
Ventilation is Carefully Controlled
Since energy efficiency is maintained by blocking the transfer of heat from outdoors to indoors, it is important for energy efficient homes to be equipped with good quality ventilation. The home needs to have a good way to bring fresh air in and remove stale air so that it remains healthy. A standard central heat and air system with clean vents and filters should provide enough air movement to keep the house feeling comfortable. Energy efficient homes provide the same comfort without the high costs of wasted energy.
