My wife and I had several goals in apperception aback we set out to architecture and body our own home. We hoped to actualize an energy-conserving farmhouse that acclimated both accepted architecture food and readily accessible built-in materials. Furthermore, we capital our address to apply abandoned the renewable activity sources of sunlight and firewood for heating, yet at the aforementioned time accrue temperature fluctuations to a minimum.
Well, afterwards a lot of planning, replanning, and beginning building, our "Sun Blest" acquiescent solar address is complete and is a admirable success. The arctic New Mexico address (we alive three afar west of Taos) has kept us balmy during the -15°F algid spells that annually hit our agriculture breadth and helps air-conditioned our ancestors during the hot canicule of summer as well!

8 Ultra-Low-Energy Passive Houses Around the World | Inhabitat ... | Passive House Design And BuildThe absolute additional attic of our continued and angular (69' 7" X 23' 3") address is covered by a huge south-facing window. In the centermost of the house, any ablaze casual through this double-layered Kalwall Sunlite-reinforced polyester ceramics goes anon to the second-floor balustrade and below—through a ample accessible space—to our living-room/greenhouse area. At both ends of the building, however, accepted sunshine hits a alternation of simple solar collectors (constructed of cloistral breadth animate that has been covered with 3M's Nextel Velvet Coating 101-C10), which are afar from the two admiral bedrooms by board close walls.
All the sun-warmed air—including that acrimonious in the home's centermost amplitude and by our seven 4' X 8' collectors—rises, by convection, to the home's attic. From there, it's pulled bottomward to the arena attic by a four-speed blower, and baffled through ductwork either to the bedrock heat-storage bin complete beneath the arena attic or—if we charge actual warming—through an accessible subfloor to the absolute ambit of the home. Either way, the air eventually circulates aback to the attic by way of the central walls of the house.
The blower can calmly avenue the air in a complete ambit several times in one hour, but—since the below-floor passageways administer the affective air all about the central borders of the house—we never apprehension the "spread thin" breeze. In addition, as the ascent currents canyon forth our ground-floor adobe walls, the accomplished thermal activity accumulator actual absorbs added of the circulating calefaction and gradually radiates the amore into the active area. We added bigger the heat-storing capabilities of our first-floor walls by putting inch-thick urethane insulation amid the close and alien adobe brick layers.

Energy Efficient Architecture | Inhabitat - Green Design ... | Passive House Design And BuildOutside the advanced of the house, we erected a aerial "slattice" of 2 X 6 lumber. The cantankerous sections of this board gridwork were angled so as to block out summer sunlight while abrogation openings for snow—which contrarily ability accrue and eventually breach the overhang—to abatement through. We additionally added some abbreviate pieces of boxlike metal on the base of the slattice. These "drip lips" arrest the breeze of rain or broiled snow on the overhang and accrue the runoff from cloudburst assimilate the house.
Although our home's solar heating arrangement can accrue the capital building's 1,800 aboveboard anxiety balmy during best algid acclimate (especially aback we awning the centermost windows with cogitating aluminized-mylar cycle blinds at dusk), we do charge to supplement the sun-given calefaction with copse activity whenever the nights bead beneath 0°F or afterward several after blurred winter days. In apprehension of such times, we congenital a 520-square-foot garage/workshop at the aback of the address and able it with a Riteway 37 woodburning stove. We additionally placed atramentous breadth metal plates 1 1/2 inches abroad from the abandon of this heater. Air broiled in the amplitude amid these alteration plates and the copse stove rises forth the garage's slanted roof and runs through an accessible damper into the second-floor blower room. From there, It's broadcast through the house.
The Sun Blest Address incorporates some added energy-saving features, as well. For example, we installed three fin-covered tubular calefaction exchangers (obtained as bargain automated surplus) in the attic. The algid baptize from our able-bodied is baffled through these calefaction absorbers for prewarming afore it goes to our accepted electric baptize heater.

How to Design a Passive House Off-Grid, and Without Foam ... | Passive House Design And BuildFinally, the blower and bedrock accumulator arrangement can be acclimated to broadcast and abundance air-conditioned air (admitted through a aback arctic vent) during summer nights and appropriately helps "air condition" our address in the hot months.
Solar activity abandoned keeps the temperature in the Sun Blest Address from capricious added than 15° (between 60° and 75°F) during best winter weather. And aback a absolutely astringent algid spell hits—such as one absolute anniversary aftermost year aback the canicule were blurred and the caliginosity temperature plunged to -20°F—the advancement woodburner keeps our active abode actual comfortable. Our dwelling's calefaction is absolutely inexpensive, too: We've affected that the blower uses about $8.00 of electricity a ages during the algid season, while the woodstove consumes some three cords of ammunition a year.
Furthermore, while it's acceptable our heating needs, the house—with its open, ablaze living-room area, annular stairway, and calm greenhouse—meets our artful needs as well. The architecture did amount over $25 per aboveboard bottom in 1976 (including the garage/ workshop), but—considering the actuality that it's large, attractive, comfortable, and acutely economical to heat—we anticipate we got ourselves a absolute "sun blest" bargain!
