Steadily since the 1960's, single family residences have expanded over 3 times in area while the average family household has decreased. Settlement patterns of the last half century have consumed vast land resources by means of carpet suburbanization at low densities. This form of ex-urban development borrows from the future through taxation and municipal subsidy that provides and maintains deep utilities and transportation infrastructure systems that are required to access these sprawling developments by the automobile.
Today's formulaic housing is largely uninspiring - garage fronted homes identical to the next on narrow lots often designed with awkward spaces that are simply tolerated or serve no tangible use. When viewed from above, vast resources are utilized for this grand housing purpose as it establishes the status quo trend of suburbanization. North America continues to rely heavily on active mechanical and electrical systems to provide comfortable indoor environments across hot and cold climates alike without being significantly responsive or adaptive. This unsustainable model of development or city making ignores basic approaches to environmental design and consumes vast amounts of energy supplied by increasingly expensive and finite fossil fuels.
Despite increasing pressure and improvements in government and society to make construction codes ‘greener’, the building code has largely remained a safety based code. Although much attention is afforded to sustainable building design in the public or institutional realm, the residential market has primarily made elective improvements for sustainble design across the housing construction market. Unlike Europe, the single family homes in America remain a largely neglected area of practice for sustainable/environmental design despite recent certification standards in place such as ‘PassiveHaus‘ or ‘LEED for Homes‘ that more positively re-configure spatial program and acknowledge the importance of building envelopes, fenestration and other systems toward a greater potential for design thinking, resource conservation and overall wellness and quality of life.
One One Ten's client brief aimed to "build an off grid, eco-friendly, affordable, modest home with the ideals of sustainability in correlation with [the client's] lifestyle". In the course of that journey, One One Ten produced an environmentally and ecologically sensitive residence for a family of three that challenged conventions by developing a climate specific design response. This was accompllished by proven means using a super-insulated, air tight envelope with few thermal bridges, a ground source heat pump combined with a Waterfurnace liquid to air ducted HVAC delivery system, a passive-solar design and net-metered local hybrid solar generative electricity producing residence that would perform at or near net-zero energy consumption annually. The goals of the project were attained within a client determined footprint and by taking strict advantage of the sustainable design opportunities available on a property borne without utility as located on the prairie. Constraints were converted into long-term advantages by scrutinizing the family's primary needs in order to capitalize on proven design strategies that address physics, climate and layer as many functions together while creating flexible program relationships with interior and exterior spaces. The project further evaluates necessity in a way that continues to respond to 21st century living in a world lifestyle proving to be less and less sustainable.
Although the project was unrealized due to a narrow budget shortfall (and perhaps, supreme lack of provincial 'green initiative' subsidies for homes) the project stands as a rare example of architecture and sustainable design in southern Alberta.
