The sunroom was a traditional passive solar feature on many farmhouses, smart carpenters would add a mudroom/sunroom. always on the south side as everybody was aware of the virtue of passive solar, and built accordingly. Here seedlings can be started in spring, and kept warm at night, , a perfect sheltered space for a workshop, potting shed, season extender.

When the leaves are gone in winter these south facing windows store heat in the floor & berms.
I also get waste heat that comes with using (average) < 425 KWH/month electricity.
I could turn on kerosene or electric heaters but last winter I coasted on sunshine.
Without heaters or A/C. Record low outside: 5 deg F while it was 47 deg F inside,
record high 96 out, while 79 inside.

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.
The house is < 40 feet from the camera.
You can see a ramp in lower right, from ground level north of house on to the north peak of the roof.
The house (blue lines) has 8 inches of earth and forest on the roof.

The Cornice -- in the Ground --" E.D.
The finished interior. Plastering upstairs was done not on lathes (phew!) but on bits of rubbish plywood (reclaimed, of course) cut to shape and with hacks cut in them with an axe for the plaster to key into. Floor wass varnished with Fiddes Hardwax oil (bit cheaper than polyx, but pretty sticky due to evaporating white spirit). Fin's curvy beam nicely on show
The Kaba near-net-zero home is primarily a passive solar home, but it also has a fireplace and electric baseboard heaters as backup for taking the chill off on cold winter days. Photo David Dodge www.greenenergyfutures.ca/episode/episode-80-chasing-net-...

This is a producing garden, and a trombe wall all in one (assuming I understood correctly). Big solar gain.
good example of solar comfort by design, with ample overhangs for summer shade.
I prefer to allow more winter light inside especially on cloudy days by having the upper roofoverhang edge higher up, have a sloping underside that goes up and out...
Breezeway w/ existing furniture. Originally it was 20 x 24, but once I drew in my furniture, I decided it could be smaller. I'm trying to $have off $quare footage to $ave on heating & building co$t.
(1 square = 1 square foot)
The bond beam that sits on top of the tires is a mixture of concrete and pop cans.

Workers roll out the vigas, long pine logs from Arizona, along the roof. They hold up the eventual metal roof.

a fine southwall design that excludes summrr heat from east and west and has a properly angled shade roof that allows winter sun inside but excludes summer heat.
The secrets to harvesting passive solar energy are triple-panned efficient, south-facing windows and a thermally massive floor that absorbs passive solar heat during the day and slowly releases it in the evening. Photo David Dodge www.greenenergyfutures.ca/episode/episode-80-chasing-net-...
