Learning Objectives

  • This session will address these questions:
  • What are the greatest challenges and opportunities for water

projects for each Installation and RSC?

  • Which types of projects are typically the most cost effective

for the Army Reserve?

  • How do I calculate the correct water rate for each project

type?

  • What resources are available for standardizing water

efficiency projects across a region or installation?

Water Audit

  • Use a proper checklist to document existing

equipment and usage patterns

– Take pictures of nameplate data – Interview facility maintenance staff

  • Use proper tools to document information

such as flow rates or building water pressure

– Water pressure gauge – Water flow bag – Leak detection tablets

Evaluation Program Directives

Energy Independence and Security Act (EISA) of 2007 Section 432 and the Army Comprehensive Energy and Water Evaluations (CEWE) Policy (23 Aug 2012) requires the Commands to: 1. Evaluate 75% of installation’s energy and water every 4 years (floor area may be used as a proxy)

  • At least 25% of facilities evaluated per year

2. Conduct comprehensive energy and water evaluations that must include:

  • Energy and water retrofit measures
  • Re- or retro-commissioning measures

focused

  • Standard: Plumbing, irrigation and rainwater

harvesting for vehicle wash

  • Remote Controls: Interval meter analysis and

benchmarking usage combined with occupancy data from controls
