Clarification on HVAC System Efficiency Requirements for LEED Compliance

Data-Centers-NC-v4 EAp2: Minimum Energy Performance
posted by Anurag Ghosh on Apr 15, 2025, 4:58 am

Hello everyone,

From my understanding, the proposed HVAC system must be more efficient than the baseline system modeled according to Appendix G of ASHRAE 90.1. Additionally, the proposed...
