Energy Code Compliance for Metal Building Systems Part 4 Case Studies

The following webinar will provide a detailed review of the common energy codes and standards used in the United States and how to apply the building envelope provisions to a typical metal building system. The program includes:

Part 4 – Trade-Off Method, DOE COMcheck: Case Studies
Detailed review of building envelope trade-off method case studies using 2009 IECC example and 2015 IECC example.

Most states and municipalities have adopted one or both of these national model energy codes either with or without state specific amendments.

Energy code provisions help to reduce energy consumption, reduce utility expenses, reduce greenhouse gas emissions, improve thermal comfort, and conserve natural resources. Energy codes and standards address minimum requirements for thermal transmission and air leakage through the building envelope, daylighting, HVAC systems, lighting, service water heating, and electrical systems. For the metal building industry, it is important to understand the code requirements for the building envelope and their effect on potential energy savings. This is especially true when considering exceeding the code requirements.

There are various methods for complying with the energy codes. The most common method for metal buildings includes the prescriptive approach that allows the design or building recipe to be based on materials and equipment dictated by the code. Another method is the performance approach. In the performance approach the designer uses energy modeling software to demonstrate that the total energy use of the proposed building is less than or equal to a baseline building. A third method is the building envelope trade-off approach. This approach allows the designer to enhance the energy efficiency of one component in exchange for an equivalent decrease in energy efficiency of another component.
