Who is Brendle Group?

What is Net Zero Water?

A pioneering, grassroots initiative focused on planning for and achieving water neutrality.

Water Neutral:

Using only as much water as falls on a site and eliminating all water quality impacts from the site.

Why this Initiative? Why Now?

• Starts with what is available to inform what is needed

• Recognizes the importance of sustainable water management, especially in the face of climate change

• Considers quantity AND quality

• Fills a gap – less developed frameworks/tools (builds on net zero climate and energy trends)

• Creates an action plan for reducing impact –developing a footprint is only the first step

TOOLKIT ORIENTATION/DEMO

Case Study 1: BG Headquarters

• Site: 13,000 sq ft

• Building: 5,000 sq ft

• Built in 1985

• Renovated in 2010

• Certified LEED Gold

• Water conserving landscape, end-use fixtures, and appliances

• Permeable pavement and rain gardens for stormwater management

Case Study 2: The Alliance Center

• Site: 15,000 sf

• Building: 41,000 sf

• Built in 1908

• Renovated in 2004

• Certified as LEED Gold

• Water conserving end-use fixtures

and appliances

Case Study 3: New Belgium Brewing

• Site: 2.1 million sf; Building: 205,000 sf

• Goal to reduce water consumption to 3.5 barrels of

water per barrel of beer this year (2014 = 3.96:1)

• Step 1: Analysis Parameters

• Step 2: Land Use/Land Cover (soils, site areas)

• Step 3: Precipitation (average and dry conditions)

• Step 4: Water Use (indoor/outdoor)

• Step 5: Water Use – Annual Growth

• Step 6-8: Water, Stormwater, and Energy Cost
