BACK TO PROJECTS

A major redevelopment of a city block in Seattle’s urban core

The Rainier Square project consists of a 60-story office/residential tower and a 12-story hotel over two stories of retail and an underground parking garage. During schematic design, O’Brien360 created models to evaluate 11 different HVAC system combinations for compliance with the 2012 Seattle Energy Code Total Building Performance (C407) and LEED® CS 2009 performance criteria. Throughout the design phase, O’Brien360 also investigated other measures to reduce building HVAC loads, including electrochromic glass and building-wide heat recovery via a central condenser water loop. Scope included coordinating a pre-submittal conference with the Seattle Department of Construction and Inspections (SDCI), as well as a proposal for Seattle City Light Energy Analysis Assistance (EAA).
