Passive Solar Farm House: Keep it Simple and Let Nature Help You
Built by Thompson Custom Builders
James Kachadorian's Passive Solar House concept is as close to an 'open source' architectural strategy as any. Originally motivated by the oil crisis of the 70's, Kachadorian developed a technique for building new homes that incurred no additional construction costs, based on completely conventional materials, including concrete blocks and poured concrete. As the patents issued on this solar system expired, Kachadorian essentially turned these ideas over to the public, and wrote a book - 'The Passive Solar House' to 'make that gift more meaningful.' The home featured here is built upon the ideas found in this book, as well as direct consultation with Kachadorian himself.
This home consists of an existing farm house, almost every inch of which required total reconstruction with careful consideration paid to energy-efficient construction techniques and mechanical systems. The new addition extending south from this farm house was built using Kachadorian's passive solar slab technique.
Aesthetically, the intention was to build a home that fit well with the timeless rural character of this region, especially that of the existing farm house. We did so by extending consistent overall massing, roof lines, window types and siding material from the farm house to the addition. The two elements are unified by a central gathering/entry core.
Internally, the addition features an open 2-story central space with a wood stove that can radiate heat throughout all of the spaces in the addition. The tall chimney minimizes creosote build-up and gives the hot chimney pipe a chance to radiate as much heat as possible into the space. This open central space is flanked on either side by open second story loft spaces that look out over the living room. These lofts can be completely enclosed by a series of sliding doors reclaimed from the existing farm house. These open lofts also enable rising heat from the passive solar slab and wood stove to radiate throughout the entire space.
Internal 'thermo-shutters' are located on each of the south-facing windows in order to retain as much of the warmth absorbed during the cold winter days as possible. They also help keep the space cool in summer by blocking excessive solar gains. The size and shape of these windows were calculated based on Kachadorian's guidelines for optimal daylight admittance throughout the year. We kept north-facing windows to a minimum, and only installed them in areas that would help offset the need to use artificial lights, enabling further energy savings.
The home is currently fit with a solar domestic hot water system, with plans to augment the system with a photovoltaic installation in the future.
In all, this home is not only a model of energy efficiency and passive solar utilization, but fit well with the family's lifestyle, the architecture of the existing farm house, and the rural vernacular character of this region.

Kodama Farm
42 Tall Tree Ln
Chimacum WA 98325
New permaculture-inspired market farm in the beautiful Beaver Valley of Chimacum. Focused on regenerative practices & soil health, Kodama grows a multitude of vegetables, fruits, & herbs specializing in citrus, mushrooms, heirloom vegetables, & unique fruit. Other projects in the works include developing a 5 acre food forest & construction of a commercial kitchen for a future CSA. Come say “hi” to our 3 adorable Nigerian dwarf goats, take a tour of the farm & the tropical geodesic dome, & learn about our sustainable gardening practices.
5-room apartments in 2 storeys. The porches has two doors each to prevent cold air from blowing inside in the winter.
27 apartments for rent, from 2-room to 5-room apartments, all with an own carport. Built: 2007. Architect: Contekton. Builder: Skanska. Owner: Uddevallahem.
For a Passive House in a cold climate no radiators or under-floor heating are necessary. The building is superinsulated and airtight and has therefore only minor transmission and ventilation losses. It is primarily heated by radiated solar energy, heat produced by humans, household machinery, domestic electronic equipment and light fittings.

Entry into our home is made from street level into the second story of the structure. Solar homes typically limit window exposure on their north faces. The public spaces are all on this level. The family private zones (bedroom, baths, office etc.) are in the lower level. The lower lever on the house in bermed into a natural south-facing slope, allowing walk-in entry into the southern reaches of the lower level. The bermed architecture contributes to the lessening energy needs for both heating and cooling of the house.

Glen Kinney next to the Water Organizing Module or WOM. This is where the water comes into the Earthship from the cisterns and is filtered three times down to five microns to make the rainwater safe to drink. The home gets all of its water from rainwater and in 1.5 years of operation the 26,000 litres tanks have never been less than half full.
