To increase water efficiency, eliminating the need for a cooling tower.
Requirements
Projects without Cooling Towers or Evaporative Condensers
Projects may earn full credit if all conditions are met:- the baseline system designated for the building using ASHRAE 90.1-2010 Appendix G Table G3.1.1 includes a cooling tower (systems 7 & 8)
- the project design case does not include a cooling tower
- the design case mechanical system does not use the latent heat of the evaporative cooling of water.
- the project does not receive any cooling from a District cooling system
General Pilot Documentation Requirements

Credit Specific Documentation
Provide documentation showing that the project meets all requirements including:- Documentation showing that the project is designated as systems 7 or 8 under ASHRAE 90.1-2010 Appendix G Table G3.1.1
- Documentation (site plan or mechanical system plan, energy model or other) showing that the project design case does not include a cooling tower or other system that uses the latent heat of the evaporative cooling of water, and is not connected to a District cooling system..
Changes
- 5/4/2016 - added clarification that projects connected to District cooling systems are not eligible
- 4/4/2017 - added as an option for EBOM v2009 projects for 1 innovation point

Cost estimates for this credit
On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.
Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.
This information is also available in a full PDF download in The Cost of LEED v4 report.
