RMC worked with the Bellingham Housing Authority to increase sustainability of three of their largest properties. Employing an integrated design approach, RMC guided the Green Communities Project involving a diverse team of engineers, consultants, and contractors at all stages of the design process. This collaboration delivered a complex project within a rigorous funding schedule. Major improvements to the mechanical and electrical infrastructure including efficient boilers, water conserving plumbing fixtures, and lighting upgrades operated by advanced controls increase efficiency, save water and help reduce energy use. These gains in energy are augmented by the installation of photovoltaic panel arrays and solar hot water collectors.
