Sponsored by Demilec and SOPREMA
Presented by Diana L. Nash and Sonya M. Pouncy

Learning Objectives:

  1. Discuss the ZNE process, including, initial assessments, air infiltration study, building modeling, the gap analysis, project management & construction integration.
  2. Review various building envelope systems, including, roofing systems, Structural Insulated Panels (SIP) and windows. Identify why certain materials are chosen and the benefits relative to energy efficiency and tightening up the building envelope.
  3. Discuss how collaboration with experts in their specific fields is essential to designing and constructing buildings.
  4. Define new energy code requirements for the building envelope and how it is impacting architects, contractors, building owners and managers, inspectors and building officials.

This presentation will be focused on best practices when it comes to the design, contractor selection, project management and construction phases of projects. The technical content will address building envelope components and systems. We will briefly touch on the other systems, such as solar and, geothermal, but the primary focus will be the roofing system, the windows, and the insulation. We will also focus on how we have leveraged the concept of collaboration in the past, and how lessons learned from that will be carried forward to future projects. Lastly, we will show the new Michigan Energy Code as an example, and how it impacts building envelope design and how it is effecting energy efficiency in the State of Michigan.
