The U.S. Department of Energy (DOE) puts a great deal of focus and concern into the area of weatherization. An abundant amount of recovery act funding went towards weatherization and in return the reduction of energy consumption. In an attempt to make the auditing and assessing aspect of weatherization readily available and understood by both experts and consumers alike the DOE has created the Home Energy Scoring Tool.
This tool is available online for free and unlike similar tools, such the Energy Star Yardstick, the Home Energy Scoring Tool does not take your actual bills or consumption into account; instead it takes the information about your home gathered by an assessor and provides you with a rank. The walk-through needed to gather information for the free online tool collects data from 45 different points. Once completed the tool will calculate your score and compare your home to other homes in your area. The tool is designed to measure the home itself, not how the home is used. To substitute for the home’s actual use it makes the assumption that it is occupied by 2 adults and 1 child and that the thermostat is set at a certain level depending on the time of year.
Upgrades and improvements are then generated by the online tool and listed so they can clearly be seen and considered. The potential savings are also generated to show users how much they could affect their costs by making the improvements. The tool calculates a score of 1 to 10 which shows how your home is currently performing; the higher the score the better the performance. After this initial ranking it compares how it currently is performing to how it could perform if all of the potential upgrades were made.
If you plan to invest in home improvements this is a great tool to help you judge which improvements will result in the biggest savings. The upgrades pointed out by the audit will result in significant savings by improving energy efficiency. But, keep in mind that these readings do not take into consideration your actual use. Your home may be completely efficient, but your bills may still be high. If you are scoring high on the Home Energy Scoring Tool but your bills are still higher than you think they should be it may be time to look at how you use energy.
A home energy monitor provides a glimpse into your real-time daily energy use habits. Using this tool you can narrow in on waste. The average home has over 30 devices that are always using electricity, whether it is a charger that is still plugged in or a device in standby mode. Some devices in standby mode use as much electricity as in the on mode. The first step in changing your habits is to detect these always on “vampire” loads and stop them. A quick glance at the monitor occasionally will assure these loads are still off. Without continuous monitoring these vampires will sneak back slowly but surely, which is why continued monitoring is required. Using the monitor to maintain these devices can result in significant savings. One device by itself does not create a significant vampire load, but 30 or more devices combined can equal a lot.
