1240 Midvale – Seattle, WA
Energy Modeling for City of Seattle Built Green Certification
The 1240 Midvale Apartments by Paar Development is a four-story mixed-use building in the Wallingford Neighborhood of Seattle. The building was designed by Caron Architects and built by Village Builders. This building has a triangular design which includes 30 residential units and retail businesses on the ground floor. Solarc Energy Group (SEG) was brought in by Evergreen Certified to model the building for Seattle Built Green Certification. In conjunction with Evergreen Certified, Solarc helped develop the energy efficiency measures that achieved the 15.5% energy savings. This building is occupied and is targeted to achieve Built Green 4-Star Certification.
The energy model was developed in DOE2 (Equest) by Eric Knowles working from Solarc’s Seattle office. Eric handled all communication and project team coordination for this project, as he does for many similar multi-family residential projects in the greater Seattle area.
