Mini-Split Heat Pumps are Quirky and Still Effective
The name "mini-splits" generally refers to heat pump systems with one outdoor unit and one or several smaller capacity air handlers. The efficiency of their operation comes via the inverter compressor and variable refrigerant…Continue
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…Continue

It happened again yesterday: a new record (tell me if you know of a tighter house in Ontario if not Canada!) for air tightness was broken in Oakville by Certified Passive House Consultant (CPHC) Ed Marion of Passive House Ontario.
And this was just a pre-drywall test, so it can only get better from here.…
As the trees start to lose their leaves and the temperatures begin to drop, we tend to turn our home heating system on for comfort. However, what most people don’t realize is that, like any other appliance, our furnace also needs regular care in order to perform at its highest as well as to last longer.
First: Clean up your Furnace
Regardless of what type of furnace you have, …Continue

Here are some warnings about portable air conditioners to help you to be aware of their low energy efficiency rating when purchasing a new air conditioner. If you already have a portable air conditioner or if a portable air conditioners your only option to get some cooling,…Continue
Aside from vacations, longer days and spending time in the great outdoors summer brings with it oppressive heat resulting in large segments of the population blasting the AC.
This often translates into long hours of high energy usage which, depending on how much its relied upon, has a tendency to become routine throughout the warmer months.
Since AC spikes power usage more than most other…Continue

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…Continue
Whether you are a “do-it-yourself” home energy auditor or a seasoned professional, learning about a home from an initial visual inspection is an important tool during an energy audit of home which can highlight energy saving opportunities. The visual inspection is the first indication…Continue
DETROIT (WWJ) - Just ahead of the official start of summer (June 20), Metro Detroit is expecting a couple of days with near record-high temperatures.
“By dinner time Tuesday, 6 p.m., we’re still looking at 91 degrees in Metro Detroit with high humidity levels,” he said.
We have record heat coming for the next couple days around Metro Detroit. Air conditioners will be on full blast and people will be roasting in their 2nd story bedrooms at night.…Continue

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…Continue
9 Steps to a More Energy Efficient Home and Lower Power Bills
How to reduce energy at home has gradually become a household desire as a result of high definition T.V.'s and homes the size of a castle. Throw in a struggling economy and the melt down of a nuclear plant and becoming more energy efficient seems like a great idea.
Our power bills rise as a result of increasing power costs and the need for more and more power to operate are power hungry homes and…Continue

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…Continue

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…Continue

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…Continue

Think of the ways we try to separate the outside climate from the inside climate. In a nut shell, that is the goal of an energy efficient house. Take a snowmobile or a dog sled and you will see a domed home made out of snow and ice.…Continue

I receive calls on a regular bases asking me about help fixing the problem of being cold and whether or not I have heard of any Weatherization Assistance Programs. These calls are not about being cold for a day - while the furnace is fixed - or being cold for a week - while a few more dollars are scraped together to have the…Continue
