Sea Water Cooled Chiller Modeling

Marcus Sheffer LEED Fellow 7group / Energy Opportunities LEEDuser Expert 5903 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...
