Energy audits in my area are done by the utility company. They start by doing a blower door test. Here is what it looks like. It's a plastic door with a blower that tells where you are loosing the most heat or cooling energy. The auditor will also walk around your house looking inside things and behind things to see where other gadgets can save you utility dollars. It's not a time for being embarrassed by dust and clutter..... because you are getting advice.... not a home cleanliness inspection.
My energy audit was about things I could do as a home owner to make my home more energy efficient. There are also ways to cut energy expenses even if you rent an apartment. I found out from the energy audit that I was loosing a lot of energy because I didn't have any insulation. Strange because when I bought this house it was supposed to be insulated. I went back to the original papers and sure enough it said fully insulated. It even described how much insulation. I did have an inspector look at the house before I bought it but I think he just wanted to get the fee because there are lots of things he didn't mention before I signed the papers. Over the years I have found the errors on my own. Without the energy audit I would never have known the insulation never was done. I'm not about to climb a ladder to get into the attic at my age.

If you get insulation all over your house you must also get air vents to lower your utility bill in the summer. Insulation to keep in the heat in winter and ventilation to get the heat out in the summer. I got 11 new vents in my house. This is one that was put on the back addition to my house. It's separated from the rest of the attic by the way it was constructed so it needed separate vents.
This is another vent for the addition in the back.
These are 6 vents put on the side roof of my house. The insulation guys cut the holes for the vents then used the holes to run the hoses inside where the other guys moved the hoses around to place the blown in insulation where it needed to go.
These are the three vents on the back side of the roof. The shorter portion of the roof is the addition. The addition doesn't have any attic space at all which is why the vents were put on the sides of the house.
My water heater got a new jacket. This may be a little over kill since the water heater is in a heated part of the house but the way I feel about it is.... even a few pennies saved by using the jacket is a few pennies in my pocket.... not the utility company's pocket. Again, cheap enough it could be left for the next renter if you got one for your water heater in a rented apartment.
I also got some new energy efficient light bulbs. Changing light bulbs in an apartment is the easiest of all things to do to save energy dollars. I already have energy efficient bulbs all over the house. The ones I have are equal to 100 lumens of light but use only 25 watts of energy. Lumens are equal to candle light. One lumen equals one candle. 100 lumens means 100 candle lights.
See the difference in the bulbs? The new ones are very small next to the old ones I was already using.
Back when I first bought this house, I studied ways to cut expenses on utilities. I had to.... no other choice... because I was struggling to keep a roof over our heads. At the time, I did all I could by using the newest items on the market. Now days the gadgets are even more energy efficient so I'm once again studying newer ways to cut down. A trip to the hardware store, a search on the internet, a book or two from the library, or any other information I can gather helps me learn to cut expenses even better.
