One roof plane. Three jobs.

Conventional construction stacks a roof membrane, then racking, then solar — three systems, three costs, one function each. The Energy Roof integrates everything into a single factory-panelized assembly.

① Weatherproofing

Flush glass-and-silicone outer skin — no exposed metal, no separate membrane. The panel is the finished roof surface.

② Solar electricity

Glass-on-glass monocrystalline BIPV across the roof plane (~180 W/m² usable), sized to the building’s footprint.

③ Heat-recovery ventilation

Smart fans, ducts & dampers in the under-panel plenum move heat where it helps: out in summer, in during winter.

Engineered, not assumed — CFD-validated thermal design

A nine-run conjugate-heat-transfer simulation campaign swept 1.5″, 3″ and 4.5″ air-gap geometries across summer and winter operating modes. The 3-inch plenum was selected — capturing ~59% of incident summer heat for removal while maximizing winter delivery. Full-scale instrumented validation (thermocouples, heat-flux sensors, airflow) is scheduled at the Rutgers EcoComplex clean-energy facility.
