Addressing Moisture Durability and Energy Performance in Roof Assemblies
Learning Objectives:
- Apply recent changes in energy codes to building enclosure roof and wall assemblies for improved energy efficiency.
- Evaluate effectiveness in existing green standards for a project’s long-term moisture durability regarding the scope and impact to the building enclosure.
- Identify how to utilize and supplement various green standards across the various project phases, including design and material selection, construction-related activities, field performance testing, and Building Enclosure Commissioning (BECx).
- Apply examples of best practices and tools to assist in designing energy-efficient and durable roofing and building enclosures.
Credits:
The requirements in green standards alone, such as LEED, Green Globes and IgCC may lack comprehensive measures to address resiliency related to the long-term performance of the building enclosure.
In this presentation, optional and required credits from various green standards will be compared regarding the scope and potential moisture durability impact of the building enclosure across the following project phases: design and material selection, construction-related activities, field performance testing, and Building Enclosure Commissioning (BECx).
It will review changes in codes, examples of roof and vertical assembly integrations, and tools to assess potential moisture challenges to enable energy-efficient and durable enclosure assemblies.
