Note:  This page is under development and may be revised as updated versions of the tool are released.

The TSPR report is composed of the following six sections:


  1. Whole Building TSPR Results and Submitter Information
  2. Building Envelope Information
  3. Whole Building Annual HVAC Site Energy Use by End Use Summary
  4. Building Block Characteristics Summary
  5. HVAC System HVAC Energy Use by End Use and HVAC System TSPR   
  6. Baseline HVAC System Description


Section 1:  Whole Building TSPR Results and Submitter Information

The first page of the TSPR report displays the whole building TSPR results for the proposed and baseline building, basic building information, a statement of TSPR code compliance and the submitter’s name and organization.


Building Information – The building information displayed at the top of the report includes the building name as entered into the tool; address; building use type (displayed as "Mixed-Use" if more than one use type has been entered); gross  floor area entered by the user; year built; the date the building was scored; and a building ID# generated by the  tool.


Whole Building Total System Performance Ratio – The proposed and baseline building TSPR are displayed, along with a statement of compliance with the 2018 Washington State Energy Code (WSEC).


Total System Performance Ratio (TSPR) is the ratio of the sum of a building’s annual heating and cooling load in thousands of BTUs to the sum of the annual carbon emissions in pounds from energy consumption of the building HVAC systems.  To comply with the WSEC, the proposed building TSPR must be greater than or equal to the baseline system TSPR.


Submitted By – The name, email, organization and phone number of the person responsible for submitting the TSPR report for compliance are displayed.


Section 2:  Building Envelope Information


Building Surface Area Summary – The total gross wall and window areas, and the window to wall ratio for the whole building are automatically calculated and displayed based on the block and window dimensions entered.  The gross wall and window areas for surfaces by orientation are also automatically calculated and displayed.  


Section 3:  Whole Building Energy Summary

Two tables summarizing the estimated energy use for both the proposed and baseline buildings are displayed.   

Whole Building Annual HVAC Site Energy Use by End-Use


Whole Building Annual HVAC Heating and Cooling Loads


Section 4:  Building Block Characteristics Summary

A list of the building data inputs that have been entered into the model by the user, or inferred by the model, and used to generate the TSPR score are displayed in a "building systems characteristics" summary for each block as a reference.


Section 5:  HVAC System Energy Summary

Note:  The Building Block Characteristics Summary and the HVAC System Energy Summary are grouped by shared Primary and Cooling systems.  For example, if 2 blocks are served by the same Water Loop Heat Pump (WLHP) but separate DOAS systems, the system TSPR would be generated for the WLHP, and would include both blocks for the DOAS system and the WLHP.
