A newly completed home in Rock Hill has achieved Passive House certification, marking a regional milestone for energy efficiency. The structure utilizes advanced insulation and solar power to minimize its environmental footprint.
Why it matters
The homeowners pursued this rigorous standard after experiencing insulation and heating challenges in their previous residence. The project aims to prove the viability of high-performance building practices in the local climate.
The home features a 20 kilowatt-hour battery system and generates 14,844 kilowatt-hours of electricity annually via roof solar panels. The 3,466-square-foot structure can operate off-grid for approximately one week.
