This high-performance recreation and wellness center in Michigan is designed to support health, sustainability, and community engagement. Located beside Ashmun Bay Park, the facility features a mass timber portal frame system that defines large interior spaces such as a gymnasium, natatorium, and indoor track. The timber structure enhances both aesthetics and sustainability by sequestering carbon and reducing embodied energy. Achieving LEED v4.1 BD+C Platinum certification, the building excels in four key areas: Sustainable Sites, Water Efficiency, Energy & Atmosphere, and Indoor Environmental Quality. Site strategies include preserving native habitat, minimizing heat island effect, and encouraging walkability. The facility generates clean energy through photovoltaic panels and solar thermal collectors. Its HVAC system combines a Water-Source Heat Pump with Dedicated Outdoor Air and Energy Recovery Ventilation to optimize energy use and indoor air quality. Carefully placed glazing on the north and south facades maximizes daylight while minimizing glare and heat gain through integrated shading. These design and engineering strategies work holistically to produce a resilient and regenerative facility that supports both environmental responsibility and the well-being of its users.
