As the building enclosure consultants, SGH reviewed design concepts for the exterior wall cladding, windows, doors, and roofs. Highlights of our work include the following items:

• Analyzed effects of thermal loading and condensation potential of metal panel wall assembly at ventilation shafts and provided recommendations for the interior and exterior air and vapor barriers
• Determined the best location for the air and vapor barriers and insulation within the metal panel and terra cotta rainscreen cladding assemblies
• Evaluated quality control, ease of detailing and installation at penetrations and terminations, compatibility with adjacent materials, and UV stability of a fluid-applied membrane and sheet membrane for installation behind the cladding
• Consulted on single-ply roofing membrane that meet Energy Star, LEED, and Cool Roof Rating Council requirements for reflectivity and emissivity
• Consulted on the photovoltaic (PV) collector field mounting system on the standing-seam metal roof and recommended a system to accommodate rain water that could penetrate through panel joints and penetrations
• Analyzed the thermal bridging effects of the PV mounting system in the context of the whole-building energy performance and provided recommendations for the placement of insulation within the assembly to reduce conductive heat flow
