5
How many pre-requisites does water efficiency have?
0
What is WE Credit 1.1?
Water Efficient Landscaping- reduce by 50%
What is WE Credit 1.2?
Water Efficient Landscaping - No potable water use or no irrigation
What is WE Credit 2?
Innovative Wastewater Technologies
What is WE Credit 3.1?
Water Use Reduction - 20%
What is WE Credit 3.2?
Water Use Reduction - 30%
What is the intent of WE credit 1.1: Water efficient landscaping reduce by 50%?
Limit or elminate the use of potable water, or other natral surface or subsurface water resources available on or near the project site, for landscape irrigation.
What are the requirements of WE credit 1.1: Water efficient landscaping reduce by 50%?
Reduce potable water consumption for irrigation by 50% from a calculated mid-summer baseline case. Reductions shall be attribute to any combination of the following items, Plant species, irrigation efficiency, use of captured rainwater, use of recycled wastewater, use of water treated and conveyed by a public agency specifically for non-potable uses.
What are the potential technologies & strategies of WE credit 1.1: Water efficient landscaping reduce by 50%?
Perform a soil/climate analysis to determine appropriate plant material and design the landscape with native or adapted plants to reduce or elminate irrigation requirements. Where irrigation is required, use high-efficiency equipment and/or climate-base controllers.
What is the intent of WE credit 1.2: Water Efficient Landscaping no potable water use or no irrigation?
Eliminate the use of potable water, or other natural surface or subsurface water resources available on or near the project site, for landscape irrigation.
What the requirements of WE credit 1.2: Water Efficient Landscaping no potable water use or no irrigation?
Achieve WE Credit 1.1 and ue only captured rainwater, recycled wastewater, recycled graywater, or water treated and conveyed by a public agency specifically for non-potable uses for irrgation or install landscaping that does not require permanent irrigation systems. Temporary irrigation systems used for plant establishment are allowed only if remove with one year of installation.
What are the potential technologies & strategies of WE credit 1.2: Water Efficient Landscaping no potable water use or no irrigation?
Perform a soil/climate analysis to determine appropriate landscape types and design the landscape with indigenous plants to reduce or elminate irrigation requirements. Consider using stormwater, graywater, and/or condensate water for irrigation.
What is the intent of WE Credit 2: Innovative Wastewate Technologies?
Reduce generation of wastewater and potable water demand, while increasing the local aquifer recharge.
What are the requirements of WE Credit 2: Innovative Wastewate Technologies?
1) Reduce potable water use for building sewage conveyance by 50% through the use of water-conserving fixtures (water closets, urinals) or non potable water )captured rain-water, recycled graywater, and on-site or municipally treated wastewater. 2) Treat 50% of wastewater on-site to tertiary standards. Treated water must be infiltrated or used.
What are the potential technologies & strategies of WE Credit 2: Innovative Wastewate Technologies?
Specify high-efficieny fixtures and dry fixtures such as composting toilet systems and non-water using rinals to reduce wastewater volumes. Consider reuisng stormwate or graywater for sewage conveyance or on-site wastewater treatment inlcude packaged biolgical nutrient removal systems, constructed wetlands, and high-efficiency filtration systems.
What is the intent of WE credit 3.1: Water Use Reduction 20% reduction?
Maximize wate efficiency within buildings to reduce the burden on municpal water supply and wastewater systems.
What are the requirements of WE credit 3.1: Water Use Reduction 20% reduction?
Employ strategies that in aggregate use 20% less wate tahn the water use baseline calculated for the building after meeting the Energy Policy ACt of 1992 fixture performance requirements. Calculations are based on estimated occupant usage and shal linclude only the following fixtures (as applicable to the building: water closets, urinals, lavatory faucets, showers and kitchen sinks.
What are the potential technologies & strategies of WE credit 3.1: Water Use Reduction 20% reduction?
Use hihg-efficieny fixtures, dry fixtures such as composting toilet systems and non-water using urinals, and occupant sensors to reduce the potable water demand. Consider reuse of stormwater and graywater for non-potable applications such as toilet and urinal flushing and custodial uses.
What is the intent of WE credit 3.2: Water Use Reduction 30% reduction?
Maximize water efficiency within buildings to reduce the burden on municipal water suply and wastewater systems.
What are the requirements of WE credit 3.2: Water Use Reduction 30% reduction?
Employ strategies thati n aggregate use 30% less water than the wate use baseline calculated for the building (nor including irrigation) after meeting the ENergy Policy Act of 1992 fixture performance requirements. Calculations are based on estimated occupant usage and shall include only the following fixtures (as applicable ot the building): water closets, urinals, lavatory faucets, showers and kitchen sinks.
What are the potential technologies & strategies of WE credit 3.1: Water Use Reduction 30% reduction?
Use high-efficiency fixtures, dry fixtures such as composting toilets and waterless urinals, and occupant senors to reduce the potable water demand. Consider reuse of stormwater and graywater fron no-potable applications such as toilet and urinal flushing, mechanical systems and custodial uses.
