Greetings, SDL network - We are attempting to resolve an issue with how data center projects calculate baseline EUIs for the AIA 2030 Commitment and could use some help from this network. With projects that comply with code prescriptively (i.e. not energy modeled), we have found the default baseline assumptions within the DDx platform are not accurate. However, we have also found issues with how the Zero Tool calculates the baselines, even with using assumed Annual IT loads (kWh) in those calculations. We have tested manipulating the annual hours to 5,482 (aligns with ASHRAE Data Center Loading %), but still encountering discrepancies. The Data Center projects we are benchmarking are Hyperscale. Does the ZeroTool account for this sizing category or is it suited for smaller Enterprise (ONPREM) data centers located within commercial buildings? How are you establishing the baseline EUI values on projects that do not perform energy modeling for reporting in the DDx?
Thank you,
