A mixed-use project in Seattle's Ballard neighborhood, the Greenfire Campus meets high-performance and social sustainability goals. The 0.85-acre project combines a five-story, 18-unit apartment building; a four-story, 18,000-sq-ft office building; and two restaurants to promote the social concept that one can live, work, play and perhaps grow food in the same vicinity.

The commercial building was designed to achieve LEED-Platinum certification, while the residential building was designed to LEED-Gold standards.

The office space is estimated to use 70% less energy per sq ft than the average office building. Hybrid natural ventilation cools the office and retail building, minimizing the use of fans and mechanical cooling. An integrated ground-source heat pump optimizes energy production. Lighting exceeds Seattle energy codes by as much as 35%, and 75% of the heat is recovered from exhausted air. In the apartment building, a solar hot-water system produces 70% of domestic hot water. A 10-kW solar system reduces purchased electrical energy by as much as 5% annually.

The Greenfire Campus is the largest project in the city using rainwater as its sole source of irrigation. Ninety-five percent of the landscaped area is planted with native or drought-tolerant plants. These include more than 60 trees and 150 plant species.
