Making a home energy-efficient, by the way it is built and through remodeling, is the way in which the greatest amount of energy-efficiency gains can be made. Homes can be made energy-efficient by making different types of upgrades. The manner in which the energy-efficiency upgrades are made can make the difference between attaining some energy-efficiency and gaining immense energy-efficiency.
To make homes more energy-efficient, more insulation can be installed than typical. Windows of better quality can be installed. Heating, ventilating, and air-conditioning systems can also be more energy-efficient than one normally sees. Drafts and air leakage can be reduced greatly from what is seen in typical construction. Other features in a home that can be upgraded, for the sake of energy-efficiency, include lighting, kitchen and laundry appliances, fireplaces, roof and siding color, and attic ventilation.
Incorporating energy-efficiency into various components of one’s home, discussed in the last paragraph, can result in a home that is a little bit more efficient or a lot more efficient than a typical home. A furnace can be a little bit more efficient than typical or a lot more efficient. For example, a furnace found in most homes is 80% efficient. A high efficiency furnace could be 90% efficient or it could be 96% efficient. The variations in energy-efficiency in all of the parts of a home—insulation, windows, air conditioners, etc.—can have a huge effect on energy usage.
When one decides to make energy-efficient upgrades for their home, they have to choose the features (insulation, HVAC, etc.) that make sense for their own situation. The selection of energy-efficient features depends on financial resources available, the condition of the home, how energy-efficient one wants to be, and one’s own energy-efficiency feature preferences.
