An acronym for what is synonymous with all that is bad with the American Pastime, Performance Enhancing Drugs (PED's) have been proven to inflate a ballplayer's performance. Most important in contract years, a player's performance is measured in specific statistics. So, what if there was a pill, or cream, that an HVAC Technician or Salesperson could take to inflate their numbers. Make them perform at the top of their field and get them the highest pay in the industry? Would you take it?…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

A significant efficiency problem in traditional green building is thermal bridging, which is a term used to describe the wooden frame of a building conducting heat. This happens because insulation is put between the studs in a wall, so the area between them is insulated while the studs themselves cannot be insulated. This phenomenon occurs regardless of insulation levels, as the studs of a frame act as bridges between the two outer surfaces of a wall, hence the term bridging. One solution…Continue

All of us have elderly relatives or friends, but have you ever considered their energy consumption patterns? On the surface, those patterns may look little different from your own, but in fact the aging population brings new needs across the whole spectrum of health, transportation, recreation, housing, and safety. And since the over-65 cohort is a growing…Continue
Back in the ‘80s, the Center for Neighborhood Technology and others helped the City of Chicago pass a residential utility disclosure ordinance that required the disclosure of heating bills when residential properties are sold or leased in the city. Why? Heating expenses constitute a significant home expense, and it’s important for consumers and Realtors to have access to this information.
Until now, complying with the ordinance could take up to two weeks: a Realtor submitted an…Continue
Energy efficiency can be a tough sell. Providing detailed information about financial savings and environmental benefits doesn’t always motivate conservation. So when rational arguments don’t work, how can we influence energy behavior? Perhaps by creating an emotional response with inclusive and engaging public art installations, such as the upcoming Northeast Green Light Project.…

Remember the word "Plastic" in that famous movie I can't remember the name of, but Dustin Hoffman was the kid. My stroke last year is no help either.
Here's the next word for all of you: THINSHELL, both with metal stud framing and without, is the single biggest development in the world of construction and the AEC industry, and I invented it about 35 years ago in Hawaii.

I remember not all too long ago, yes I am still on what I hope to be the first half of my life, that Central Air-Conditioning was a luxury. Like the radio, then the television; next the telephone, and now the cell phone, Air-conditioning has become a necessity. What was before Air-Conditioning? What did the weather people (yes, politically correct here on Excess Air) say to the elderly before they would recommend "staying inside, out of the heat"?
I remember what I used to do…
