MN BEC Meeting: Sept 22, 2015

Building Enclosures for the Future – Building Tomorrow’s Buildings Today

This half-day educational session will cover the latest in building enclosure technology for energy efficient buildings. Presented by one of North America’s leading building science research engineers, Graham Finch of RDH Building Sciences will provide an in-depth discussion of emerging wall and roof assemblies that provide durable, cost effective and thermally efficient performance.

Recent building and energy code changes will be reviewed including an opportunity to discuss solutions to meet these more stringent requirements. Current building science research and field monitoring information will be presented, demonstrating how insulation materials perform under different climatic conditions and how R-values change with time and season. Strategies to construct highly insulated wall and roof assemblies and avoid thermal bridging will be presented, along with several case studies to illustrate how these emerging technologies have been utilized in new and existing buildings.

The seminar will cover all building types and construction materials, with a few highlights and lessons learned from the construction of building enclosures for new 5&6 storey wood-frame buildings.

Learning Objectives (3 AIA Credits)

  1. Review and understand recent changes to local building and energy codes that impact building enclosure design strategies and whole building energy efficiency.
  2. Understand the building enclosure design requirements for wall and roof assemblies and how the selection of the right materials are critical to reliable long-term performance.
  3. Learn about several emerging design strategies including various cladding attachment systems are being used for the construction of highly insulated wall assemblies and how to apply these technologies to projects.
  4. Learn how different conventional roofing membrane combinations and insulation strategies can affect in-situ thermal performance and resulting heating and cooling energy consumption in buildings.
