Wood Fiber Insulation Arrives in the USA

Looks like wood-fiber insulation board is coming to the USA, according to a Greenbuild update on Green Building Advisor.  Agepan THD is the name of the product and it’s used as exterior sheathing for walls and roofs.  Agepan boards connect in tongue and groove fashion and insulate to R-5.74 per panel (2″ x 74.5″ x 23-5/8″).  The material has a high permeability (18 U.S. perms) and can be used in a wall assembly to dry to the exterior.  It’s offered through Washington-based The Small Planet Workshop Store.

Passivhaus Apartments Built in Sweden

A couple years ago, Kjellgren Kaminsky Architecture and builders Höllviksnäs Förvaltnings AB won an open competition for four Passivhaus homes on a vacant lot in the city of Malmö, Sweden.  The team won the competition and the low-energy houses are now finished.  The project may be referred to as Salongen 35 and includes a greenhouse, green roof, gray water treatment, and solar panels.

Specifically, solar panels provide about 40% of annual hot water needs, while 82% of energy in the indoor air is recovered through a heat exchanger.

The exteriors were finished with plaster, fiber cement, wood, and aluzink (for the roof), and the interiors have whitewashed pine, brushed pine, and recycled terracotta, depending on the area.

All wood is FSC-certified, and the appliances are top of class for energy efficiency to keep in line with the Passivhaus regime.  Salongen 35 also has dashes of greenery here and there with flower boxes, lawns, green walls, a green roof, and the greenhouse that is used for local food production.

This isn’t KKA’s first work with Passivhaus — another great project is their Villa Nyberg.

SunShower SSIP House Built in NOLA

In September 2010, I mentioned the winning design in a competition involving steel SIPs from OceanSafe.  The REOSE Sunshower SSIP model, designed by Tulane University professors of architecture, Judith Kinnard and Tiffany Lin, is now complete and demonstrates a home that can withstand hurricane-force winds and extreme weather while still incorporating the latest in energy- and water-saving technologies.

Located at 222 Harrison Avenue in New Orleans, Sunshower SSIP House was built with readily available, off the shelf materials that fit in a single cargo container.  The idea is that a kit of the same materials could be deployed elsewhere to create a home fit for post-disaster recovery.

The Oceansafe SSIP panels are made with an EPS core and galvalume panels that snap together to withstand winds of up to 225 mph and an earthquake of up to an 8.6 magnitude.

Sunshower has about 1,050 square feet with two bedrooms and two bathrooms.  Part of the roof is optimized for 5 kW of solar panels, while the other funnels water into a 1,000 gallon Rainwater Pillow.  The home also benefits from solar thermal, geothermal, a small wind turbine, and back-up batteries.

Woodward Design + Build and C&G Construction built the Sunshower SSIP House with sustainable design consultant The Regen Group for a total estimated construction cost of between $110,000 – $150,000 (roughly 60 vendors contributed materials to the home).

Passivhaus Rainbow Duplex in Whistler

This is a follow-up with new photos to our original coverage of an affordable Passive House duplex located near an affluent ski resort in British Columbia.  Referred to as the Rainbow Duplex, the home was designed by Marken Projects and built by Durfield Constructors with a high-performance, panelized prefab system by BC Passive House.

Located at 8448 Bear Paw Trail in Whistler, the new duplex uses up to 90 percent less energy for heating, cooling, and building operation than a standard house.  That being said, chasing performance didn’t stop the project team from also complying with the affordability requirements of Whistler’s Price Restricted House Initiative.

Each side of Rainbow Duplex includes about 1,500 square feet plus an unfinished basement with four bedrooms and two bathrooms.

Rainbow Duplex is the “first Passive House to be solely constructed in B.C. using primarily local products,” according to a recent statement.  Pre-certification review was completed last year, and Alexander Maurer of Marken Projects is waiting for Passive House certification from the international office located in Darmstadt, Germany.

This high-performance home has R47 walls, an R60 roof, cross-laminated timber floors and deck, solar hot water, a Zehnder HRV, sub-soil heat exchanger, Mitsubishi mini-split heat exchanger, triple-pane wood windows, and bamboo floors, to name just a few products and materials.
