A Day of Passivhaus Immersion in New York City

New York Passive House presents a one-day symposium on many of the region’s exemplary new-construction and retrofit projects

Posted on Jun 20 2012 by Richard Defendorf

Although the idea does have a certain appeal, for most of us it would be impractical to tour all of the approximately 40 completed or in-progress Passivhaus projects in New York. But a one-day symposium focused on a selection of these projects would be easily manageable and, it turns out, is already on the calendar.

Aiming for Passivhaus in Boston

Powahouse, a three-unit, three-story condominium under construction in the city’s Roxbury neighborhood, is on track to meet the standard

Posted on May 22 2012 by Richard Defendorf

It might have left a few people feeling especially uneasy about climate change, but the Northeast’s strangely dry, mild winter did at least allow construction to continue at a relatively brisk pace on Powahouse, a three-unit condominium going up on a corner lot in Boston’s Roxbury neighborhood.

10 Projects, Each Presented in 10 Minutes and 10 Slides

The 10x10x10 Green Building Slam showcases residential and commercial projects that emphasize green principles

Posted on Mar 26 2012 by Richard Defendorf

There is something to be said for playing fast, if not loose, with the facts when it comes to presenting the essentials of a building project. Or at least that’s the driving concept behind the 10x10x10 Green Building Slam, scheduled for Wednesday at the Magic Lantern Theatre in Spokane, Washington.

Energy Positive in Oregon’s Painted Hills

A solar-powered ranger station wins an award at the International Builders’ Show

Posted on Mar 12 2012 by Richard Defendorf

There isn’t much tree cover at the site where the Department of the Interior built a 1,002-sq.-ft ranger cabin for the National Park Service’s Painted Hills unit, which presides over part of the John Day Fossil Beds National Monument in north central Oregon.

But the sun exposure in this spectacular and remote location is being played to advantage with a 5.6-kW photovoltaic system that, combined with a well insulated and relatively airtight shell, helped earn the gird-connected house a HERS Index rating of -46. (The targets were -15 with the PV system, +44 without.)

Passive House in the Woods Goes Energy-Positive

A PV array helped a Passivhaus project in Hudson, Wisconsin, exceed net-zero-energy performance in 2011

Posted on Feb 27 2012 by Richard Defendorf

As the clock wound down on 2011, marking a full year of monitoring for Passive House in the Woods, in frosty Hudson, Wisconsin, it became clear that the building’s design, construction, and renewable-energy systems had combined to deliver net-zero-energy performance, and then some.

Teaching Deep Green by Building It

Students at the Endeavour Centre in Ontario, Canada, are studying design and construction by building a home billed as the country’s “greenest”

Posted on Feb 23 2012 by Richard Defendorf

The project is being called Canada’s Greenest Home, which sets the bar pretty high, but the Endeavour Centre, a nonprofit building school in Peterborough, Ontario, decided the time is right.

Endeavour encourages its students to engage their minds and “get their hands dirty” on ambitious projects, including this 2,000-sq.-ft. two-story home, which is designed for an infill lot in Peterborough and will be the focus of the school’s five-month Sustainable New Construction certificate program.

Local Food and Resilience

Producing more of our food locally and selling direct to consumers are keys to achieving resilience

Posted on Feb 16 2012 by Alex Wilson

In this final installment of my ten-part series on resilient design, I'm taking a look at where our food comes from and how we can achieve more resilient food systems.

The average salad in the U.S. is transported roughly 1,400 miles from farm to table, and here in the Northeast, we get most of our fresh food from more than 3,000 miles away. Even in Iowa, where 95% of the land area is in agricultural production, one is hard-pressed to buy locally grown produce.

Trekhaus: A Passivhaus Duplex in Oregon

A design/build team applies its know-how to this well-insulated, airtight duplex on an infill lot in Portland

Posted on Jan 17 2012 by Richard Defendorf

Updated to reflect the installation plans for the photovoltaic systems.

Work is very nearly completed on TrekHaus, a duplex built to the Passivhaus standard in southeast Portland, Oregon. At some point this spring, if all goes according to schedule, the west unit will be equipped with a 4.14 kW roof-mounted photovoltaic system and monitored for performance for a while before a similar system is added to the east unit. Once the renewable-energy systems are in place, the building is expected to operate at net zero energy with three people in each unit.
