By following strict “passive house” standards, a multifamily affordable-housing complex in Portland, Maine, slashes heating costs. “Sometimes we turn off the heater because we feel so good,” says one resident.
The modern tendency to look at the old ways of doing things as some sort of backward stage of human development is being proved misguided again and again. In this story, heating and cooling costs are slashed by using an approach that, in part, taps the wisdom of first century BC.
Story Hinckley writes at the Christian Science Monitor, “Cities like Portland, Maine, have realized this energy-efficient design for the affordable housing sector – for residents who can really benefit from lower heating costs.
“Passive house-certified buildings are slightly more expensive to build upfront, but the heat and electricity bills are less than half of what it typically costs to heat a similar building in Portland.
“Passive house design is more than just an architectural novelty, says the team behind Bayside Anchor. It is also a necessary tool for residents or homeowners who care about long-term affordability. As the need for affordable housing grows across the United States, proponents say cities should move beyond building low-income housing as cheaply as possible. …
“Says Greg Payne, director of the Maine Affordable Housing Coalition and development officer at Avesta Housing, the nonprofit affordable housing provider that manages Bayside Anchor, ‘We have to promise that [the building] will be affordable for 45 years.’
“Before moving to Bayside Anchor two years ago, MD Islam, his wife, and their two young children lived in a home without heat.
“ ‘We had to suffer a lot,’ says Mr. Islam, who works at a local recycling plant. ‘Now my family – everybody – is happy. We feel very comfortable.’
“A high-tech ventilation system exchanges indoor air with fresh air from outside, all while retaining the temperature of the indoor air. Thick walls (with 10 inches of insulation, in Bayside Anchor’s case) and triple-pane windows keep the building airtight so very little heat escapes. Instead of a central heating system, each apartment has a small electric baseboard heater. …
“ ‘Sometimes we turn off the heater because we feel so good,’ says Mr. Islam. …
“Property manager Lucy Cayard [says] the passive house design has helped her build a deeper connection with the residents. Since much of the building takes care of itself, the building’s staff can put their time and resources elsewhere.
“ ‘We get to focus more on people’s needs and not the building’s needs,’ says Ms. Cayard. …
“The concept of passively heating and cooling a building is probably as old as architecture itself. Writing in the first century B.C., the Roman architect and military engineer Vitruvius observed that buildings in warmer climates tended to have northern exposures, with windows facing away from the sun, while those in cooler climates had southern exposures. Modern passive house techniques trace some of their history to energy-efficiency efforts in the U.S. during the OPEC oil embargo. The principles underlying Bayside Anchor’s design are further based on techniques honed by scientists in Europe in the 1980s and 1990s. …
“But with a national shortage of 3.7 million affordable rental homes, according to a recent report from the National Low Income Housing Coalition, new building approaches need to be explored. For example, says Mr. Payne, almost 600 households are currently on the waitlist for one of Bayside Anchor’s 36 affordable units.
“ ‘We are watching it happen all across the country,’ says Jesse Thompson, the Portland-based architect behind Bayside Anchor. ‘What’s different about Maine is that it’s the affordable housing folks who are the most progressive, who are moving the most quickly.’ ”

Yay, Portland! About an hour from where we live.
A beautiful part of the country!
Thanks! We think so, too.
Isn’t it interesting that even the property manager could see the positive of being able to focus more on the residents than on building upkeep?? I hate the idea of people being miserably cold–no one should have to experience that, in America, in the 21st century . ..
Yes, and it’s good to know that the property manager really wants to help residents.
