• MA- Energy Modeling for Commercial Compliance Pathways (Parts 1- 4)

  Understand the modeling requirements associated with the Targeted Performance Path and the Relative Performance Path for MA Commercial Stretch Energy Code compliance. Comprehend the modeling requirements for special cases including core-and-shell projects and first-time tenant fit outs. Develop a high-level, basic understanding of MA Stretch 2023 mandatory requirements and the types of 90.1 mandatory requirements that projects are required to comply with. Understand how to use energy modeling results to extract the information needed to demonstrate compliance with the Targeted Performance Path. Learn to establish model inputs for specific systems and components. For example, OA CFM rates for the Targeted Performance Path. Articulate energy modeling requirements of the Relative Performance Path that deviate from the ASHRAE 90.1 Performance Rating Method. List the documentation that must be submitted to code officials for projects following performance paths of compliance.

• C.01 MA Commercial Stretch Energy Code: Targeted & Relative Performance Paths (Part 1)

  The Targeted Performance path requires projects to use energy modeling to demonstrate compliance with the heating and cooling Thermal Energy Demand Intensity (TEDI) targets. This training will review performance path code requirements, including energy modeling, documentation, special rules for additions and alterations, core-and-shell requirements and others.
