Owner: Providence Housing Development Corporation | Location: Rochester, NY | Completion Date: Ongoing
Programs Achieved: Passive House, NYSERDA Buildings of Excellence, NYSERDA New Construction – Housing Tier 4, DOE Net-Zero Energy Ready, EPA Indoor Air Plus Qualified, Energy Star Multifamily New Construction
To assist Providence Housing Development Corporation, SCI conducted WUFI energy modeling targeting low carbon construction and Passive House PHIUS+ 2018. The project received $1 Million Building of Excellence award for low carbon construction. The project features all electric systems including heat pumps for heating, cooling, and Sanden split system air source heat pump hot water heating, advanced insulation to meet PHIUS+ 2018, and solar production to achieve Net-Zero energy. SCI will also serve as the PHIUS+ Verifier to confirm all program requirements are met through construction and will conduct training on high-performance building practices.
