Fact Sheets

What is Total System Peformance Ratio (TSPR)?

This fact sheet provides a general overview of the purpose of this  mechanical requirement and how this performance ratio is calculated. Also refer to training videos about the TSPR webtool on the On Demand Training webpage.

 

Commissioning Fact Sheet (PDF 2.6 MB)

Commissioning significantly increases the likelihood that technical details such as system configurations and flow rates, occupancy and temperature settings, and record drawings are correct and complete. Getting these technical details right can have a significant impact on the long-term performance of the building systems. Commissioning requirements in the WSEC elevate the priority for this important step in the construction process. This fact explains the basics of commissioning and when it is required per the WSEC.

 

Smart Service Water Heating Circulation Pumps Fact Sheet (PDF 2.5 MB)

Service water heating circulation systems are used in commercial buildings to maintain the design supply temperature in the primary piping loop. The WSEC requires this system to have a circulation pump with controls that manage the water temperature in the circulation system and turns off the pump when there is no demand for hot water. This strategy saves energy and reduces water use by minimizing the time required for hot water to reach a fixture.

Smart circulation pumps offer a better than code strategy that simplifies installation and operation with integrated sensors, programmable control logic and ECM motors. This fact sheet provides information about this strategy and links to helpful resources.
