Thermal Bridging Impacts on Offices (Curtain Wall Construction)
Vulnerable points in conventional curtainwall and storefront construction
Sponsored by NYSERDA
This course will cover the following: Introduction to Prototype Office - the general program, system descriptions, and review energy loads of code compliant building. It will zoom in on envelope system assumptions in prototype Basis of Design, Thermal performance and thermal bridge accounting and Air leakage assumptions vs. designed and tested for performance The Impact of thermal bridging on heating and cooling loads - model reflecting revised envelope system performance with thermal bridge accounting and realistic air leakage, Other impacts of reduced thermal performance and air leakage, strategies to reduce thermal bridging and design reduced air leakage, and Connect Envelope performance impact on electrification goals and clean grid targets

LEARNING OBJECTIVES
- Describe 2020 ECCCNYS building enclosure thermal performance requirements for curtainwall and storefront assembly types.
- Review the impact of envelope performance on building energy loads in common office buildings Identify frequent thermal bridges and other vulnerable points in conventional curtainwall and storefront construction.
- Communicate design solutions that mitigate thermal bridging in curtainwall and storefront
- Explain how enclosure performance impacts office building operations and supports state-wide low-carbon goals.
