Making your home more energy efficient is a cost-effective way to not only save money but to also improve the performance of your home. The most effective strategy for improving your home’s energy efficiency is to focus on the “shell” of the house…the walls, attic, windows and doors. Next, improve the energy efficiency of systems such as heating, cooling, lighting and appliances. Last, but not least, consider clean energy generation such as solar or geothermal.
The first step toward energy efficiency is to make sure that your walls and attic are well insulated. High quality insulation slows the rate that heat flows out of the house in the winter or into the house in the summer. That means it takes less energy to heat or cool your house. If your walls have no insulation, it will certainly pay off to have blown-in insulation and it will also improve the comfort of your home. If you have an unfinished attic, it is worthwhile to upgrade its insulation. It is a good idea to use an Energy Auditor to make sure that the insulation is installed properly.
The next step is to upgrade or replace windows. If your windows are old or leaky, it is time to replace them with energy efficient models or to increase their efficiency by using weather stripping and storm windows. While it’s not usually cost-effective to replace windows just to save energy, if you are going to replace them anyway, the additional cost of Energy Star-rated replacement windows is very modest and is a comfort improving upgrade that is worth the cost.
Another way to save some energy in your home is to plant shade trees and shrubs around your house. If you have an older home with poor insulation and windows, good landscaping can help, especially if planted on the house’s west side. Deciduous trees are the best way to go for this purpose. During the summer, the foliage will block the infrared radiation that would warm the house, while in the winter the bare branches will let the radiation through.
Replacing an older HVAC system with a new high-efficiency system may seem like a huge expense, but in the long run it will save energy and money.
You can improve the efficiency of your hot water system by turning down the temperature of your water heater to the “warm” setting (120 degrees F). You can also insulate your hot water lines so that they don’t cool off as quickly between uses. And using low-flow fixtures in your showers and baths will help as well.
You can use ¾ of the energy used with incandescent light bulbs by replacing them with LEDs. You may not realize that the cost of the electricity used to run a light bulb is more than the cost of the bulb itself. A LED may be a little more expensive than the traditional light bulb, but it will save money & last 1000s of hours.
You can save money with an energy efficient home in many ways, including the tax benefits that are available to you. Federal tax incentives are out there for energy efficiency upgrades to existing homes.
