Wisconsin Passive House owner says drop on by anytime!

“I want as many people to come into this house as possible. Anyone who reads this can knock on my door and I’ll give them a tour. The whole point is to share and learn from each other, to take ideas from here and do them elsewhere.” – Sonya Newenhouse

With Carly Coulson as the certified Passive House designer. This tiny (968-square-foot) kit house has a treated floor area of 888 square feet (82.5 m²). This project sports local windows and Cardinal triple-pane glass, while the doors are Energate. The NewenHouse is wrapped in a jacket of cellulose – and similarly comes in well under the specific space heating demand.

Carly recently presented the project at the Hannover Passivhaus conference. Here are some of the project specs:

  • Space heating demand: 11.4 kWh/m²a (3.61 kBTU/ft²a)
  • Primary energy demand: 104 kWh/m²a (32.9 kBTU/ft²a)
  • Blower door: 0.51 ach50
  • Wall U-factor: 0.09 W/m²K (R-63)
  • Slab U-factor: 0.10 W/m²K (R-57)
  • Roof U-factor: 0.06 W/m²K (R-94)
  • (7,795 HDDs)

The project is also rocking a solar domestic hot water system (Velux) that is expected to provide nearly two-thirds of the domestic hot water needs, and a PV system for site net zero energy.

The project went through BRE in Watford, UK, for Passivhaus certification, is Energy Starcertified, and is expected to hit LEED for Homes Platinum after Landscape verification by the Green Rater Laura Paprocki.

Total cost for NewenHouse – including solar DHW, PV, and accessory structures – is a whopping $173/sf. If there was a LEED Titanium, this über-tiny Passivhaus in an “extreme” environment would surely qualify.

Newenhouse, who aptly describes herself as an eco-entrepreneur, is also founder and president of Community Car LLC in Madison, and just sold the Madison Environmental Group, a business she founded 13 years ago, to an employee. In the next year, she plans to launch a business selling three house designs — a 500-square-foot one-bedroom, an 800-square-foot two-bedroom, and a 1,000-square-foot three-bedroom. An option for a detached stuga, Swedish for “cabin,” includes storage space, a root cellar, sleeping loft, sitting area and wood stove. With her business, Newenhouse says she is trying to bring together three movements: the green building movement, the small house movement and the sustainable- or simple-living movement.

You can contact Newenhouse at 608-220-8029 or Sonya@madisonenvironmental.com. A link to her blog is on the a at madisonenvironmental.com. Or if you’re planning to drop in, which she says she welcomes, she lives at 422 Hickory St. in Viroqua WI.

LEED for Homes Myth #3: The costs are expensive

Recently, many people have told me they thought a LEED for Homes certification was going to cost many thousands of dollars – even over $10,000.  This simply isn’t true, at least not when using the Green Home Institute () as the LEED for Homes Provider.  So let’s bust this myth. Read more

LEED for Homes Myth #2: Documentation Requirements

How difficult is it to document a LEED for Homes project? Many people are familiar with LEED projects done under the commercial rating systems, such as Interior Design and Construction (ID+C) or New Construction, now known as Building Design and Construction (BD+C). Or perhaps you have heard about the large binders of documentation that a project team has to assemble and submit to the USGBC for review and final LEED certification.

LEED for Homes requires less documentation than other LEED rating systems

If you think LEED for Homes has equally difficult documentation requirements, think again.  The reality is that documenting a LEED for Homes project is quite simple.  The main submission is a small packet of pre-formatted documents, the LEED for Homes Project Checklist, which are generated from a single MS Excel file with multiple tabs for different submission information. Best of all, the forms are bundled together in the one single Excel file. Read more

LEED for Homes Myth #1: FSC lumber

Forest Stewardship Council (FSC)

Forest Stewardship Council (FSC)

Sometimes, a LEED for Homes project team comes to the table with the expectation that they are required to use FSC-certified lumber in their LEED for Homes projects. Perhaps this comes from confusion with other LEED rating systems used for commercial construction, which does have a prerequisite for Forest Stewardship Council (FSC) lumber. Read more
