While heating and cooling loads drive up energy costs there are other common energy deficiencies that are often overlooked. A DIY home energy audit can help you determine what these are. While aspects of an energy audit relating to the building envelope are pretty straight forward, finding sources of inefficient lighting technology is a little less intuitive.
with this tool.
The benefit of knowing how much energy a light source consumes in a typical day is beneficial because it can be directly translatable to the amount of money owed on an energy bill. Simply multiply the number of kilowatt hours off of the usage meter by the local utility rate. Right now, utility rates average around $0.11/kilowatt-hour.
With this knowledge it is very simple to see what lighting consumes the most energy and where to make energy efficient upgrades. If a homeowner does a DIY energy audit and sees that certain lights are left on more during the day
unnecessarily; they can employ the use of an occupancy sensor or vacancy sensor light switch in order to save more money on their energy bills. Residential occupancy sensor light switches or ceiling mounted occupancy sensors combined with LED lighting are more affordable than many people realize. Most importantly energy efficient lighting supplies are a very financially smart choice because they never need to be replaced and will provide continually growing energy savings over their lifetime.
