Red Cedar is the second of three apartment projects that Auburn Mechanical has completed as part of the Yesler Terrace redevelopment for the Seattle Housing Authority (SHA). Auburn performed full-mechanical engineering, design, and installation for the job. The HVAC scope included variable refrigerant flow (VRF) and in-unit energy recovery vents (ERVs). In addition to plumbing for 119 residential units, the project included a solar preheat system. Auburn Mechanical also provided all the piping for the refrigeration and set of significant equipment.
