Marilyn Specht Vice President & Managing Principal, US Sustainability Introba LEEDuser Expert 51 thumbs up May 3, 2017- 12:37 pm Hi Trina, Who told you to do that? My understanding is they do not require the changing room to be separate from the shower area. This is also discussed in the LEED CI-2009 SSc3.2 forum where it is confirmed you do not need separate rooms for the two. Log in or register to post comments ...

Sea Water Cooled Chiller Modeling

NC-v4 EAp2: Minimum Energy Performance

Marcus Sheffer LEED Fellow 7group / Energy Opportunities LEEDuser Expert 5796 thumbs up April 26, 2017- 9:45 am I think this would be possible with some type of water cooled condenser. Without going into the program and trying to figure it out I can't give you a step-by-step set of instructions. For LEED if it can't be modeled directly a work around would be required. If it is required make sure to follow G2.5 and provide a thorough narrative describing the work around. You might also consider posting your question on the eQUEST users forum at onebuilding.org. Someone there would be more likely...
