The building size is mandating to model the baseline with a water cooled chiller and I will compare the baseline with the design which is using HVAC that is (air cooled chiller + ice storage efficiency 30%+ diversity).
when I compared the results of the energy model between the total baseline energy consumption and the total energy consumption of the design , I found that I achieved 12% reduction (fulfilled the prerequisite requirement).
my questions are:
1. Is it accepted to model the design with the energy of HVAC considering air cooled chillers + diversity + ice storage
2. Should I be prepared to provide any evidence or clue on this HVAC scenario
