HEET Barnraisings—a green twist on an old idea


You may remember the scene from the 1985 movie Witness starring Harrison Ford. A group of Amish people converge on a neighbor’s property and assemble a barn in a single montage, a single day. A Cambridge-based co-op  HEET (for Home Energy Efficiency Team) does weatherization work that’s less lofty, but arguably more important to the modern world. It’s a model for what can be done by harnessing the power of progressive community which emerged during the Obama campaign.

As Bob the Builder might say, ‘Can We Caulk it? Yes we can!’

Combining the materials purchased by the homeowner with free knowhow and labor from HEET, the team has weatherized several low-income  homes in Cambridge, with the goal of performing a barn-raising per month. As they do so, they transfer the skills needed to make—and keep— a home more energy efficient to both homeowners and groups of new volunteers. The energy savings persist, putting cash in the pockets of Cambridge residents, which can be spent in the local economy in different ways—a Cambridge mini-stimulus.

HEET grew out of neighborhood organization called GreenPort. The purpose of both groups, according to co-founder Steve Morr-Wineman, is to bring neighbors together to respond to the environmental crisis. A recent project included weatherizing the Cambridgeport Public School, a pioneering public-private-volunteer collaboration with the savings going back to Cambridge’s tax-payers.

Daily KOS thinks the model needs to go national, and so does Warm Home Cool Planet.

Somerville, MA will soon hold their first weatherization barnraising and Watertown, Brookline, Lexington, Medford, Milton, Newton, Beverly, and Boston are thinking about starting their own groups.  I think it would be a good idea for this idea to go nation-wide.  In fact, a weatherization barnraising on the White House might be a very good way to kick-start that process.

Our hats off to the HEET team. You’re doing great work. Expect to hear from us soon.

This weekend, Warm Home Cool Planet received a message from Lands’ End specifically targeting everyone shivering their way through winter here in Massachusetts.

You know it’s cold when folks from Wisconsin are sending you winter sympathy messages via email. Beyond how cold it might be outside, the recent patch of artic weather here in Cambridge has resulted in lots of time spent inside for most residents. For Warm Home Cool Planet, that also means plenty of time to ponder why the ground floor of the house is always colder than the floors above.

A quick search around the Internet revealed a wealth of information on how most houses–particularly those built before the 1970s–don’t have properly insulated crawlspaces.

So if your bottom floor feels like a skating rink, find out why crawl space vapor is reducing your comfort–and increasing your heating bills. We also recommend looking at your all your options for properly sealing and insulating your crawlspace. Depending on the situation under your house, you need to check your polyethylene sheet has the right thickness, and you have the right kind of membrane to deal with moisture build up under your flooring.

Energy Rebates by the Square Foot

The details of an interesting program to encourage energy efficiency in Utah just crossed our desk here at Warm Home Cool Planet.

The Energy Services Efficiency Program… eases the financial burden of making large changes that lower the energy load on the power grid, such as better insulation, more efficient air conditioning systems and improved swimming pool pumps.The rebates could pay more than $500 for improved attic insulation, $350 for a new air conditioning unit and up to $125 for a better swimming pool pump.

Warm Home Cool Planet supports this idea because it achieves two things. It ties the reduction of energy use in each house to specific improvements, and it helps the homeowner make the capital investment in what are becoming tough times for all. Looking at the photo below, it seem like the folks in Utah are getting with the program too:

Larry Morrison, also with Morrison Insulation, said when he learned about such rebates last year, he started alerting all of his customers to the possible benefits. He said it costs about 50 cents per square foot for a typical installation, while rebate programs would reimburse for 35 cents per square foot – as both the St. George and Questar programs do.

Energy Efficient-from the ground up.

From the Laconia Citizen:

“It was 30 degrees outside but inside a yet-to-be-finished basement of a home being built on Summit Road, the temperature remained above 42 degrees, with no heat.

That’s because the home, which belongs to Cecilia Rai and James Koren of Plymouth, is being built to be energy-efficient from basement to attic.”

Note the use of ICFs (Insulated Concrete Forms) in the outer walls. This is becoming a popular technique for including insulation in the construction process-particularly as it is independent of material used (stucco, brick, vinyl siding, wood…) for the outer walls.

The Passive House

The concept of ‘Passive Houses’ has been gaining some currency recently. On first glance it doesn’t sound terribly exciting. From this article in the Portland Daily Journal of Commerce, however, you can see that creating a passive house requires homeowners to take a number of active steps towards building or renovating a house that requires very little energy for heating or cooling. Apparently, the benchmark of a passive home is one where less than 15 watts per square foot is used to heat and cool the house during the entire year.

Most of the world's Passive Houses are located in Germany or Scandinavia

If you need more information on Passive Houses. Or as the Germans, who invented the concept, call them (PassivHaus), there’s always Wikipedia.

It started with a small water stain on the dining room ceiling that nagged at Alex Cheimets.

By the time he finished fixing the leak, his house was clad in insulation so thick he needed special 10 inch screws just to attach it to the siding. And the MA State Government had signed on a sponsor for his $100,000 home improvement project.

Part of the state’s payoff will come after the work is done. Sensors will measure humidity and help track heat loss. A blower test with a giant fan will see just how tight the home is sealed. An oil tank sensor will track oil use at different indoor and outdoor temperatures.
