AERO radio spot

      This is the text of the public service announcement I recorded for the Alternative Energy Resources Organization, which aired in early March on Missoula’s public radio station, KUFM.  You can listen to it at, but I don’t think it will be posted there for a few weeks.

          Back in the 1970s, after the OPEC oil embargo there was a flurry of interest in energy efficiency.  I remember public service spots on the radio and on TV reminding us to turn off lights we didn’t need to have on, to turn down the thermostat, to carpool, and, of course, there was the one in which Jimmy Carter famously put on a cardigan.  I was living in Boulder, Colorado at the time, and I remember seeing a lot of energy efficient homes going up: two foam houses, a geodesic dome house, a rammed earth house and a straw bale house – all of which might have been even within walking distance of each other. This was Boulder, after all: a hotbed of hippies.  Surely some of those atypical houses were demonstration homes, funded by the university or some foundation, but some were built by forward-thinking people who just wanted to save some bucks on heating costs.

          Things sure have changed since then, and I don’t just mean in terms of hairstyles, body piercings and online shopping.  What I’m concerned about is that today it is a lot harder to get a loan to build an innovative, energy efficient home.  Back then, many, if not most banks were portfolio lenders, meaning that they lend you money for your house and they keep that loan for the full thirty years.  Today, most banks write mortgages with the intention of later selling them on the secondary mortgage market.  When they sell that loan, it has to conform to the standards of the federal mortgage guarantor, Fannie Mae.  They won’t guarantee a mortgage on an atypical house.  Partly this is because there aren’t statistics on the resale value of unusually constructed homes.  Partly its because the average home appraiser doesn’t have the skills or tools to evaluate atypical construction techniques. It’s easier to just limit lending to typical, stick-frame construction.

          Today there are lots of tax rebates and other incentives to use Energy Star appliances, windows and other things, but those won’t do any good if no one will write a mortgage on the house in the first place.  There are specialty lenders who will write loans on unusual homes, but they charge a few extra percentage points to compensate for the risk they perceive.  The free market of mortgage lending doesn’t respond well to innovation.

          I learned this first hand when I built an underground home in Neihart, on the north side of the Little Belt Mountains.  The design included solar-thermal heat, passive geothermal heating and cooling, passive solar mass and a number of other elements.  When I was ready to get a mortgage on this super-efficient, elaborately engineered home, I was shocked to find out from the appraiser that there was no way in heck I’d ever get a regular mortgage on it – simply because it wasn’t a stick-frame house.  Just outside Great Falls, Ken Thornton, a former coal power plant boilermaker turned green builder is in the midst of constructing a similar, super-efficient, partially buried, passive solar home.  He was unable to get a construction loan for the project.  Who knew? This is silly. It makes no sense to penalize people who build green homes with disadvantageous mortgage rates.

          Short of changing Fannie Mae, this is where our state government needs to step up by providing incentives for banks to write loans that make it attractive for people to employ proven and innovative energy-saving building techniques.  Basically the state could act as a guarantor similar to Fannie Mae, only for unconventional green buildings.  Energy experts at the Department of Environmental Quality could work with non-governmental organizations like the US Green Building Council, the Alternative Energy Resources Organization, The National Center for Appropriate Technology, the universities, banking and professional builders associations to develop a loan system or criteria.

          One step in the right direction is the federal Energy Star certification program for homes.  This is a program that every new home-builder should try to take advantage of but unfortunately, it isn’t available for the most innovative designs. What is definitely needed is for the lack of affordable loans on green homes to be recognized as a real hindrance to reducing our carbon footprints and saving money on our energy bills.  It’s time for our elected representatives and lenders fo find a way to finance energy-saving innovation in this state.  We Montanans need to step forward; we can’t wait for a federal fix to Fannie Mae.

          If you’re concerned about the limits to innovative green building, let your elected representatives know that it’s time to step forward. I’m speaking for the Alternative Energy Resources Organization.  AERO welcomes your comments and perspectives.  AERO is a grassroots membership organization working to help create farm, food and energy solutions for communities throughout Montana.
