Minnie Howard Campus

SGH consulted on the design and performed building enclosure commissioning (BECx) for the below-grade waterproofing, exterior wall assemblies, curtain wall systems, and roofing. Highlights of our work include:

• Reviewing the building enclosure design for constructability, condensation resistance, air and water tightness, and thermal performance
• Assisting with enclosure design and helping develop details for atypical enclosure conditions, such as transitions between:
  • Projecting canopies and arcades and the main building air/water barrier
  • Air barriers at humidified pool space and the adjacent building
  • The greenhouse enclosure and roofing and cavity wall systems
  • Horizontal waterproofing (e.g., terraces) and vertical walls clad with metal panel rainscreen and brick masonry assemblies
• Helping establish and validate performance expectations by developing the BECx plan and specification, outlining testing requirements, and establishing procedures for documenting and resolving construction-related issues
• Providing construction phase services, including reviewing submittals, observing building enclosure construction and testing, and helping address field conditions
• Conducting performance testing, such as:
  • Whole Building Air Leakage Test per ASTM E779
  • Chamber Testing at Stand-Alone Mockup per ASTM E783 and ASTM E1105
