Applications

Copper was developed with building energy code development and adoption in mind, and has been used by and integrated in different applications. Examples of such applications include:

• Total System Performance Ratio (TSPR) analysis tool: The TSPR is a way to derive a global HVAC system coefficient performance measure that can be used to establish compliance by comparing it to a baseline building design TSPR. Pacific Northwest National Laboratory has developed an analysis tool to enable jurisdictions to use the TSPR approach for building energy code compliance. Copper is used by the TSPR analysis tool to generate chiller performance curves for baseline and user models.

• Addendum bd to ASHRAE Standard 90.1: Copper was used to generate sets of performance curves for chillers to be used in a baseline chilled water plant model in two performance-based approaches defined in the standard.
