Whole building system metric needs to be done to improve energy efficiency, but comes with some challenges.

#SummerStudy20
Total System Performance Ratio (TSPR) evaluates the ENTIRE #HVAC system & can be calculated by:
#BuildingSystems
Free software is available to improve whole building analysis, thanks @eeregov !
buildingenergyscore.energy.gov
Pilots of this project and approach indicate:
- reduction of #CO2 & saves #NaturalGas
- easy to use (2 - 10 hrs to finish)
- valuable code-compliance tools
- faster than whole building modeling approach
- rethink system design, useful for interpreting results
#HVAC #ASHRAE
TSPR fills the gap between
Simple & Inexpensive --> Complex & Expensive
TSPR drives down #HVAC energy use & #CO2 emissions
