Imagine knowing the refrigerant charge was correct on a Central Heat Pump or A/C without attaching gauges! No, I am not referring to the Lennox "Approach" calculation, which I have found to be very unreliable to predict refrigerant charge, but instead using the simple total capacity calculation with the correct tool.…
Often, when homeowners make improvements to an existing house, the most important aspects of home performance – including safety, comfort, energy efficiency, durability, and environmental impact – are literally invisible during key steps of any home sale or refinance transaction.
One result is that energy…Continue
My home has 3 pocket doors whose open track areas I have caulked well best as I can from the door jams without removing the track or framing around it. I believe I should attack the remainder of the leaks from the attic and from the basement. Are there any folks out there who might share their thoughts on the recommended methodology for best doing this? Thanks much in advance. John Harper

If studies are to be believed, Dux Airoheat pumps can save up to 25% of the energy consumption in an average home. However, before…

Used car salesmen get a bad rap, and there are good reasons for that. But I think the home performance community can learn from them in some important ways. I say that as someone who once had a serious case of buyer’s remorse, but got over it.
When I first moved to California I was working at an independent bookstore in Berkeley, and I liked the idea of not having a car. But after a year I realized that I couldn’t get everywhere I wanted to go in a timely manner on BART (Bay…Continue

If you own the home that you're living in, any changes you make to its design will be largely aesthetic unless you are doing large-scale renovations. If you are looking to buy a home, or if you're just interested, thinking about a home's design in relation to energy efficiency can be very important. Energy efficient design isn't just a matter of good insulation and an efficient HVAC system; the actual form of a building has a lot to do with how much energy it uses, especially when it comes…Continue

Two years ago I reported dramatic reductions in my home energy use on this blog. Between 2007 and 2009 I cut my gas usage by 34% and my electric usage by 55%. Needless to say I was pretty pleased with myself for this achievement and none too shy about spreading the news. I was also happy to share because I believed that my experience could serve as a model for others seeking to lower their energy bills and…Continue

There's a new development going up in Allston, a neighborhood to the west of downtown Boston. It's not just any development though, it's called the Allston Green District, and its being built by the Mount Vernon Company of Boston. The development is comprised of 500 units designed to have a very low environmental impact, from sustainable building materials to the “green lease” that tenants sign before they move in. These apartments were in a desirable location to begin with, but with the…Continue

Do you ever wonder why people continue to make unsustainable choices even when they are educated about the impact of their choices and the benefits of making different ones?I do. There are, of course, many reasons why people (myself included) do not choose green–from the perception or reality of added cost, to the inconvenience, to the difficulty of changing ingrained habits, to the structural…

We often hear that reducing energy use is good for the environment, and it most certainly is. What we don't often hear, maybe because it's too complicated, is how the energy portfolio of your area affects your environmental impact and what your energy efficiency upgrades will mean. An energy portfolio is basically the breakdown of what sources an area, a state for example, uses to generate electricity. Different energy sources have different environmental impacts; coal creates a lot of air…Continue
