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
