Field of Dreams EcoCommunity

High-Performance Affordable Housing in Kearns, Utah

The Field of Dreams EcoCommunity is AJR's effort to re-imagine the affordable housing typology in the Southwestern States of the US. The Field of Dreams EcoCommunity consists of twenty, 1,500 square foot units in ten twin-home buildings, newly constructed on an abandoned baseball field in the township of Kearns, in close proximity to Salt Lake City, Utah.

The Challenge

The Field of Dreams EcoCommunity is a case study pilot project for 20 low-income housing units on an abandoned baseball field in Kearns, Utah, to extensively redesign the characteristic Salt Lake Valley low-income home into superefficient, two-story Pilots. Designed to a contemporary, timeless architectural expression, and as close to Passive House standard as the tight budget allows, the building's energy-consumption for heating, cooling and domestic hot water is modeled to be reduced by roughly 60%, to be achieved through strict passive design and employment of an innovative Active Building Compact Core as the system core for each building. On the educational side, the project was used as a Pilot for University of Utah School of Architecture and other students, to demonstrate how to design, develop and construct efficient and cost-effective housing for a low-income demographic.

Performance

The first two units reached a HERS (Home Energy Rating System) rating of 39, which means energy consumption is 61% less than the comparable code-standard building, with the buildings designed as close to Passive House standard as the budget and the client's construction abilities allowed, to offer very high thermal comfort and indoor air quality. With construction cost per unit at $160,000 (including land and fees), each unit is well within affordable housing measures of Salt Lake County (Utah's maximum limit for affordable housing is $250,000).
It is anticipated that this new housing typology and micro neighborhood development will lead the path to affordable, resilient housing that is adapted to its respective climatic region and immediate urban surroundings. The successful development of this pilot project will put the Field of Dreams EcoCommunity at the forefront of sustainable and affordable construction, with findings expected to influence the construction market along the Wasatch Front and far beyond.

Fire Safety

In times of severe global climate change, Utah is especially affected by prolonged periods of draught and extreme temperatures during the summer and fall months. Stark forest and bush fires have almost become the new 'normal', with the fire season already extended by several months. To accommodate for those changes in the local climate, the Field of Dreams EcoCommunity houses are protected by a continuous layer of non-combustible materials along their exterior perimeters: Hardie-board concrete facades, metal roofing, concrete and glass are the exposed materials of choice. As a result, the Field of Dreams EcoCommunity houses will withstand fires and traveling ember and sparks much better than the standard residential building in the region, adding additional peace of mind to the building's energy and performance resilience.
