Each home is a unique structure that offers varying options for improvements. In my current neighborhood I can walk down my street and I know that the same home floorplan is repeating itself every 4-5 houses (thanks to the wonder of tract housing). Since my home was built in 1979 and still has existing insulation levels(less than 6" in ceiling, R3-5 batts at firred masonry walls) and windows that are single pane, it doesn't take long to start compiling a list of all of the places that I am gaining or losing heat in my home. Obviously the economy is currently a limiting factor in people being able to make home improvements, but sadly most people are unaware that there are inexpensive options that can still help lower their utility bills.
The purpose of an energy audit isn't to tell you that your single pane windows and insulation are insufficient, it is to inform you of options available to you in terms that make sense.
Electrical usage- including what part lighting(bulbs), appliances, electronics play in that usage and the factor most often forgotten: the heat that each component produces as it uses electricity and the affect that it has on your HVAC for the house.
Gas usage: what your appliances consume with respect to BTU's(heat in most cases) they produce, the efficiency of the combustion process and the resulting air quality that exists in your home. Not only do we check that gas burns efficiently, but we have the tools that allow us to verify that you are not losing it through gas leaks(if occurring within home) which cost you money and create unsafe scenarios.
Just remember while a home naturally is around a lot longer than a car, it still is important that we make sure it functions properly and do those alterations that will improve its efficiency and save us in the long run from wearing out the HVAC equipment faster than its intended life span.
I like what the Building Performance Institute states on their website:
"You understand that your car is made up of interacting components and systems – when one component fails, it affects the performance of the entire vehicle. Do you know that the same goes for your house?
High energy bills, uneven temperatures from room-to-room, drafts, moisture, mold, mildew, poor indoor air quality, ice dams, pest infestations, seemingly uncontrollable humidity levels and even premature deterioration of building materials can all be the result of a breakdown in the relationship between the systems in your house – the building envelope (shell), heating and air conditioning (HVAC) equipment and you, the occupants.
If one system has a problem, it impacts the other systems’ ability to function properly. Treating the obvious symptom without knowing the real culprit behind it can actually make the problem worse or create new problems. The process of elimination approach just causes frustration as you try solution after solution – investing more time, money and energy – without resolution.
Properly diagnosing and fixing the root cause requires a house-as-a-system approach based on building science.When you choose a BPI certified professional or accredited contracting company, you get a member of the elite – someone who has proven that they have the knowledge and skills to diagnose the root cause of the problems in your house and the ability to provide solutions to fix it right the first time.
That means you get your money’s worth – a comfortable, safe, durable home with improved indoor air quality and lower energy bills."
