BP04: Water Audit & Planning

Official language

This best practice sets the stage for long-term efficiency planning for your building by quantifying the costs and savings associated with building-specific water efficiency opportunities. The auditing process helps diagnose the causes of inefficiencies, identify low-hanging fruit for improvements through minor projects or operational tuning, and sets the stage for longer-term planning by evaluating potential capital projects. The audit will examine historic water consumption data and water-related systems to identify potential savings opportunities.

This best practice intends to help the building operator identify water-saving and operations and maintenance improvement opportunities through a holistic, qualitative evaluation of all water-using systems within the building or tenant-controlled space.

 

Objective

At least once every 5 years, perform a water audit to help understand the project’s water consumption profile and discover opportunities for improvements through no- and low-cost water conservation measures along with considerations for capital improvements.

 

Submittal Requirements

The following are the required submittals in order to fulfill the objective of this best practice.

 

A water audit report for the project performed within the last five (5) years contains the following information:

  1. Date of audit.
  2. Current water use analysis for the building or tenant-controlled space including:
    • Water cost intensity (WCI)
    • Water use intensity (WUI)
  3.  Breakdown of water use by major equipment, systems, fixtures, or end uses.
  4. Recommendations for conservation opportunities including no-cost and low-cost efficiency improvements.
  5. Economic analysis results.

 

Tenant-Controlled Space Participants

Tenant-controlled space participants may submit a water audit for the building to if 1) the submitted audit was performed within the last 5 years, 2) the participant was a tenant within the building when the audit was performed and 3) the audit includes the items outlined above.

 

Projects Without Water-Using Fixtures

This best practice is not required for program participants with zero water-using fixtures. Please submit blueprints or a similar document with a brief narrative explaining the project layout.
