Carbon Challenge Winners Announced

Projects focused on lowering greenhouse gas emissions.
Two architecture firms have been honored for their winning designs in the Carbon Challenge, a home-design competition that challenged participants to consider the environmental impact of building materials.
The competition, open to building designers nationwide, focused on two types of homes in two cities—a Habitat for Humanity house in Providence, R.I., and an urban row house in Baltimore. Using life-cycle assessment software from the Athena Sustainable Materials Institute, designers were able to determine the impact of the greenhouse gas emissions from the products in their designs.
For Carbon Challenge Providence, entrants were tasked with designing a Habitat for Humanity house for a vacant lot in the city’s Olneyville neighborhood. ZeroEnergy Design’s winning entry is a wood-framed four-bedroom, two-bath home with a gabled roof suitable for the neighborhood’s traditional architecture. By combining an airtight, well-insulated building envelope, high-efficiency windows sited for optimal solar orientation, a 7.5-kW solar array, and a range of other features, the house is designed to use less than half the energy of a code-built home. Other features include rain barrels to collect water for landscaping, a two-track driveway to decrease impermeable surfacing, and an insulated basement.
