22	SALEM HISTORIC HOMES Challenge: Rehabilitate wood framed and clapboard historic homes to create 100 units of affordable housing. Rehab must conform to US Park Service historic preservation standards while achieving an EnergyStar® Rating and employing “sustainable” building practices. Solution: PSC’s design took advantage of the inherent leakiness and thermal inefficiency of the buildings’ balloon framing and wood clapboard to create a source of ventilation to preserve the historic clapboard. We then devised a secondary air and thermal barrier within each stud bay to achieve Energy Star® thermal performance. Where clapboard replacement was necessary, we used a sustainable cement-fiber board.
23	FAISON MEWS Challenge: Rehabilitate existing masonry three-story building and construct new adjoining frame three-story building to produce 60 units of seniors housing while achieving an EnergyStar® rating and using Sustainable building practices. Solution: Use recycled cellulose insulation as thermal break and air retarder at exterior masonry walls; employ careful water management for sub grade area and wall systems. Use cement fiber siding in lieu of vinyl, provide community garden and storm water cistern for irrigation of flower beds.
