Intent

To increase water efficiency, eliminating the need for a cooling tower.

Requirements

Note: This pilot credit is an alternative compliance path to the LEED v4 credits Cooling tower water use (BD+C), Cooling tower water use (O+M) and Cooling tower water use (O+M: Data Centers) for the maximum number of points under each credit

BD+C and O+M v2009 projects may use this pilot credit for 1 innovation point

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

All other system types are ineligible for credit.

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..

Documentation should be uploaded under the Cooling Tower Water Use credit form in LEED Online.

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
  • 1/17/2019 - added as an option for BD+C v2009 projects for 1 innovation point

What does it cost?

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.

Documentation toolkit

The motherlode of cheat sheets

LEEDuser’s Documentation Toolkit is loaded with calculators to help assess credit compliance, tracking spreadsheets for materials, sample templates to help guide your narratives and LEED Online submissions, and examples of actual submissions from certified LEED projects for you to check your work against. To get your plaque, start with the right toolkit.
