Total System Performance Ratio (TSPR) Website

 

This training video provides an introduction to the HVAC Total System Performance Ratio (TSPR) code compliance path. The presenters discuss what TSPR is, when it is required by code, and how it is calculated. They also provide a click-through demonstration that highlights key features of a web-based simulation tool that can be used to test a proposed building’s compliance with TSPR.

The presenters are Heather Burpee who is the Director of Education and Outreach at the University of Washington’s Integrated Design Lab and Supriya Goel, Senior Research Engineer at the Pacific Northwest National Laboratory. Duane Lewellen with Lewellen Associates moderates the Q&A and assists behind the scenes.

After reviewing this Introduction video, refer to Snapshot Trainings 1-8 for specific pointers on how to use the TSPR tool.
