Gerber Plumbing Fixtures LLC is proud to offer water conserving plumbing
products that meet the highest standards in green homebuilding. In 2009,
LEED (standing for Leadership in Energy and Environmental Design) increased
the certification process for energy and water efficiency allowing for
Gerber’s plumbing products to help earn LEED certified points.
Did you know that in April 2009, Gerber provided an Ultra Dual Flush
toilet and WaterSense certified Allerton faucet to the first LEED certified
home in the Midwest? It is now time to promote Gerber’s water-efficient,
low-flow fixtures and our relationship with water-conservation
organizations like WaterSense. The information below serves as a guide in
the LEED certification process and the points earned by installing our
products.
Defining LEED:
LEED is a
rating system devised by the United States Green Building Council (USGBC).
Its purpose is to create and implement universally understood and accepted
criteria for evaluating the environmental performance of a building and
encourage global market transformation towards sustainable design.
As of 2009, LEED version 3 is based on a 100-point scale (plus a
possible 10 bonus points for the last two metrics) and provides weighted
rankings of the following metrics: Sustainable sites, Water Efficiency,
Energy & Atmosphere, Materials & Resources, Indoor Environmental
Quality, Innovation in Design, and Regional Priority.
There are four LEED Certification levels:
- Certified = 40 - 49 Points
- Silve = 50 - 59 Points
- Gold = 60 - 79 Points
- Platinum = 80-110 Points
The following provides ways to increase your LEED points in various
categories (source: David Dubrino, 2009). Water Efficiency Credit Category:
Water efficiency accounts for 10% instead of 7% of the points in the LEED
2009 (or LEED v3) ratings system. The baseline for achieving water
efficiency is a minimum of 20% water savings and is a prerequisite for LEED
certification.
Fixtures that Promote Water Conservation:
REDUCE
BY 30 – 2 points
REDUCE BY 35- 3 points
REDUCE BY 40% – 4 points
LEED-NC 2009 has increased its baseline rates for certain plumbing
fixtures compared to previous scales (eg. LEED-NC v2.2). The following is a
list of LEED 2009 baseline rates (Plumbing Systems & Design, 2009):
| Fixture |
LEED 2009 baseline rate |
| Toilets |
1.6 gpf (3.5 gpf for blowouts) |
| Urinals |
1.0 gpf |
| Lavatory faucets, private* |
2.2 gpm at 60 psi |
| Lavatory faucets, public |
0.5 gpm at 60 psi |
| Lavatory faucets, metering |
0.25 gallon per cycle |
| Residential kitchen faucets |
2.2 gpm at 60 psi |
| Showerheads |
2.5 gpm at 80 psi |
| Pre-rinse spray valves |
1.6 gpm (no psi specified) |

has changed from LEED v2.2 compared to LEED v3 in water efficiency:
Credit 3: Water Use Reduction
• Credit 3 is now worth 2-4 points for a 30-40% reduction
in water usage
