We have an upcoming international new construction project of a multi-family residential building. Due to its numbers of stories LEED NC v4 is the most appropriate rating system to use.

ACP- No Cooling Tower (Core & Shell v4)

CS-v4 WEc3: Cooling tower water use
posted by Anke Koch on Dec 12, 2017, 3:38 am

Hi Concerning the part 1 of the question refers to ASHRAE 90.1 and Cooling type: Chilled water (which by default is expeted to be prepared by Cooling Tower). Thus, if based on 90.1 your building should have system 7 or 8 (with Cooling tower) your baseline building (refer to Optimized Energy Performance credit) has it and designed does not, you comply with the requirements. Concerning the 2) part I am sure it considers EITHER, thus whether system #7 or #8. FAQ (https://leeduser.buildinggreen.com/forum/acp-no-cooling-tower-core-shell-v4) also confirms my understanding of the interpretation. Log...
