When windows aren't the culprit of a leaky building, solve the mystery with an energy audit.

Liz Vogel replaced the windows and updated the heating system in her small multifamily building in the Logan Square neighborhood of Chicago. But she still noticed that parts of her home were not staying warm in winter. So she set out to solve the mystery of the missing heat. She saw icicles hanging from her roof, and that was a clue that pointed to where heat was escaping. The presence of these “ice dams” meant that Liz was paying to heat her roof and melt the snow instead of heating her…

10 Ways to Cool a House Without Air Conditioning

Sleeping on the front porch after a hot summer day was a straight out necessity. The upstairs of the 1940’s farm house had turned into a sauna and sleeping in the upstairs bedrooms was not possible. Even after the sun went down, the upstairs seemed to get hotter. Let's look at some ways to cool a house without air conditioning?

Now that I spend time trying to figure out how a home can be more energy efficient, I think back to those hot summer days and wonder two…

Conventional AC is not COOL

In order to feel comfortable in the cooling season conditioned air has to be at the right air temperature AND relative humidity. Conventional AC dehumidifies when it is running but it is thermostatically controlled by air temperature only. Which means that when air temperature is reached the AC turns off and stops dehumidifying. Not a big problem if you live in an arid climate such as Pheonix but if you live in New England where the summers are very humid and not…

Home Energy Audit With a Hole in the Wall

Why is there a heating register 4 feet up on the wall?

by Don Ames,   www.detectenergy.com

In my last article, I spoke about a home energy audit and the hot tub on the back deck. Remember, it was a manufactured home with a great deck overlooking a roaring hillside stream. Next door, the neighbors were the countryside recyclers, at least I suppose that's what they might call themselves.

Personally, I think I would call them by a…

What is Air Sealing

What is Air Sealing and How can it Save Energy?

by Don Ames, www.detectenergy.com

Air sealing is important because air leaks through the walls, floor, and ceiling of your home. Air leaks out of your home when the air pressure inside the home is greater than the air pressure outside the home. Air also travels from hot to cold. The bigger the hole and the greater the pressure or temperature difference, the more air…

Heat transfer: How Heat Gets Out of Your Home and Costs You Money.

by Don Ames,  www.detectenergy.com

Heat flows out of your home in two ways, transmission and air leakage. Transmission and air leakage occur through all surfaces of the home - walls, floor, roof, windows and doors.

The amount of heat transfer depends on two factors: thermal resistance and surface area. Thermal resistance has to do with the quality and quantity of the material in the walls, floor, roof, windows, and…
