CESA 1060 - ZEB Enclosures: Airtightness and Assembly Details

Centre for Energy Systems Applications Part-time Studies Course

School of Construction and the Environment

Course Details

This course takes a deeper dive into airtightness and assembly details to further develop understanding and techniques that will be needed for success with the upper steps of the BC Energy Step Code. Students will advance their construction knowledge and skills with respect to building envelope design, construction and performance verification of residential buildings (Part 9 Buildings). Student hands-on work will focus on specific strategies to ensure airtightness of final assembly with an emphasis on detailed solutions for managing critical control barriers in split insulated assemblies . The course will develop more understanding of the assembly details and construction methods for higher performance above-grade walls, below-grade walls and roofs. Student hands-on work will focus on approaches to meet the thermal performance (TEDI) and airtightness (ACH) metrics of the BC Energy Step Code using various materials and techniques for detailing interfaces, windows, and penetrations. Students are expected to have some prior knowledge of the BC Energy Step Code and building science.
