I live with 8 other people in a coop in Cambridge, MA.

We've been asking our landlady to insulate the house we live in for years now. We were able to have her schedule an energy audit because she asked us for a rent increase a couple of months ago.
So last week she and her son and her handiman and a professional from Nstar (our energy company) came and did an audit. It turned out that insulation was the cheapest thing tha they could do. AND 3/4 of he cost is free through government and company grants. The rest is budgeted through a zero interest loan program. Amazing, right? I think that the loan program is available only because she keeps a room in the house.
So now I only wish I had though of suggesting an audit earlier. I can't wait to not have to wear a sweater AND a scarf inside all winter. We'll happily keep using space heaters if we can get insulation up.
Do you have any stories about helping landlords go green?
