Emerging Trends in Building Enclosure Design, Delivering High-Performance Buildings
|OnDemand Webinar||$199||Add to Cart|
Heightened performance is the single most driving trend in the building construction industry. Expectations from owners and society regarding the performance of buildings are on the rise. The building enclosure is the single biggest determinate of building energy consumption and therefore drives building performance. Litigation and numerous failures have also lead to increasing pressures for the constructed building to meet or exceed performance criteria established in the design phases.
This course establishes the heightened performance demands on the building enclosure, demonstrates scientific design tools to predict performance and provides quality assurance/quality control strategies to verify that the final building performances as expected. How both new and existing materials can be used in high-performance enclosure assemblies will be explained. Critical areas for detailing will be highlighted.
- You will be able to define performance criteria for the building enclosure.
- You will be able to discuss methods to ensure quality and verify performance during the construction phases.
- You will be able to identify scientific methods to predict the proper performance of the enclosure during the design phases.
- You will be able to explain the impact of new requirements for energy savings impact the building enclosure and how even common tried-and-true assemblies may no longer function.
