Seavey Crossing is a 61 unit accessible affordable senior housing project under construction as part of a mixed-demographic housing campus development called Maple Grove Neighborhood in Westbrook, Maine.  

Project team members from Simons Architects and Hebert Construction will discuss how prefabricated, panelized wood walls, elevator shafts, floors, stairs and roofing, have allowed construction time to be reduced and minimized exposure risks.  With 20 ft length panelized technology, the number of panels and setting efforts are reduced and on-site framing is minimized.  

The team will share how using these panels made of renewable materials for elements such as the elevator shaft was more cost effective and reduced the projects embodied carbon load by reducing the amount of concrete used. 

Though the project is not pursuing PHIUS Certification, the session will explain the value of using WUFI hygrothermal analysis, and how specific practices used and experience gained on previous Passive House are being implemented in this project to maximize energy efficiency in envelope performance and mechanical systems as well as acoustic comfort.  Sustainable material specifications will also be discussed.
