Description
When the Building Envelope Thermal Bridging (BETB) Guide was launched in 2014, the impact of thermal bridges were largely overlooked in North America. Comprehensive thermal calculations factoring in thermal bridging are now a requirement in many new energy codes and standards due to an increased understanding of their impact and drive to net-zero construction. The next progression is to recognize that structural requirements need to be factored into thermal calculations. This evolution requires reliable data that is readily available, so that cost effective solutions can be efficiently examined.
This presentation illustrates this progression with a case study where various claddings and back-up walls are examined from a structural, thermal, and cost perspective. Design assist tools with extensive data sets are showcased to illustrate how optimization can happen early-on in design and how these tools can support specifications that encourage cost effective solutions.
This presentation draws from a research project that is significantly expanding the BETB database and developing web-based applications that reduce the effort to optimize the building enclosure. This paper is supported by experience on new construction projects where these approaches have been successfully applied.
