Completion: 2014
Building Size: 67,000 sf
Energy Use Index: 22 kBtu/sf-yr (modeled)

A complete remodel of an historic 1926 brick building in the Capitol Hill neighborhood of Seattle. The existing façade was maintained and 1 floor of retail and 6 floors of residential were added

What We Did and How

Ecotope provided mechanical and plumbing design and energy efficiency and LEED consulting services. The building is built around an open courtyard configuration which eliminates central building mechanical systems and provides each apartment with cross ventilation for natural cooling. An innovative Reverse Cycle Chiller system harvests heat from the parking garage to heat domestic water for the apartments.

The Results

The project is targeting LEED Platinum certification and is expected to be one of the most energy efficient multifamily buildings in the region. It was supported by energy efficiency grant money from Seattle City Light and research money from Bonneville Power Administration’s Emerging Energy Efficient Technologies (E3T) program.
