LEED Green Associate - Water Management

  1. 1. Water Management LEED Green Associate Study Course Ben Schaal – Betsi Slane – Anne Ficeli – Bret Mackey – Kelley Mattice – Sue Bierlein
  2. 2. Introduction: Water Management W ater is one of, if not the world’s most vital natural resource. All building projects should include water efficiency as part of their plan. LEED projects require water management & water efficiency as part of the building process. <ul><li>How... </li></ul><ul><li>Plan early </li></ul><ul><li>Over achieve guidelines and requirements </li></ul><ul><li>Practice frequent measurement & benchmarking </li></ul><ul><li>Seek professional expertise </li></ul>
  3. 3. Indoor Water Management <ul><li>W ays to reduce indoor water consumption: </li></ul><ul><li>1. Use water conserving fixtures ( LEED points ) </li></ul><ul><li>Low Flow toilets - modern HET’s use 1.28 GPF vs common fixtures; 3.5-5 GPF </li></ul><ul><li>Waterless Urinals </li></ul><ul><li>High Efficiency Fixtures, Faucets, and System Location </li></ul><ul><li>Behavioral shifts and awareness </li></ul><ul><li>2. Direct or sub-meter suites/units for water usage (Additional) </li></ul><ul><li>Case studies show tenants and building occupants who are responsible for their own water usage bill decrease their consumption by 15% on average </li></ul>
  4. 4. Outdoor Water Management <ul><li>W ays to reduce outdoor water consumption: </li></ul><ul><li>1. Use local adapted plants ( LEED points ) </li></ul><ul><li>Native plants survive and consume less water due to natural survival vs. irrigated survival </li></ul><ul><li>Drip irrigation for trees, shrubs and ground cover </li></ul><ul><li>High efficiency spray heads and other equipment </li></ul><ul><li>Weather based irrigation controls </li></ul><ul><li>2. Non potable water irrigation ( LEED points ) </li></ul><ul><li>Using rain run-off water and other recovered “wastewater” reducing clean water consumption and energy. Onsite collection or Municipally provided </li></ul>
  5. 5. Process Water Management <ul><li>W ays to reduce process water consumption: </li></ul><ul><li>1. Cooling Tower - Commercial Buildings ( LEED points ) </li></ul><ul><li>Limit potable water for cooling tower usage </li></ul><ul><li>Water management plan that addresses chemical treatment, bleed off and condensation run off </li></ul><ul><li>Conductivity metering and automation controls </li></ul><ul><li>Utilizing non-potable water for process water systems </li></ul><ul><li>2. Heating and Cooling of water ( LEED points - different category) </li></ul><ul><li>Solar thermal water heating </li></ul><ul><li>Geothermal water heating/cooling </li></ul><ul><li>CHP - Combined heat and power systems; thermal boiler steam turbine systems and condensation collection </li></ul>
  6. 6. Water Management LEED Points <ul><li>LEED Points/Credits for Water Management </li></ul><ul><li>In all 3 categories variations in points can be calculated from increased efficiencies based off of baseline assumptions or existing building consumption measurements. </li></ul>
  7. 7. Water ... in the Future <ul><li>Outlook on Water in LEED & Society </li></ul><ul><li>As increases in global demand for clean water rises; our prediction is the emphasis on water conservancy and responsible use in LEED rating systems and other green practices will grow as well. </li></ul>Water Consumption Stats & Factoids * Reducing hot/cold water consumption also reduces the use of electrical and natural gas consumption to heat and cool related water sources * 884 Million people globally do not have access to safe water * 2/5th’s of the world population does not have access to adequate sanitation * Agriculture accounts for over 80% of the world’s water consumption * If current trends continue, 20 years from now humans will use 40% more water than they do now
