Save water, save lives

  1. 1. Save water, Save lives, Be sustainable?
  2. 2. Should we save water?
  3. 3. Table of Content• Why should we work on water saving?• How could we save water in the Sustainable Buildings?• How much water saving percent could we reach?
  4. 4. • Why should we work on water saving?• How could we save water in the Sustainable Buildings?• How much water saving percent could we reach?
  5. 5. Why should we work on saving water?The Impacts of building on resources in United States:• 40% Primary energy use• 72% Electricity consumption• 39% CO2 emission• 13.6% Potable water consumption
  6. 6. Why should we work on saving water?1- the water consumption:• In 2006 the broadcasted water consumption for the year of 2010 was 12%.• Now in the year 2010 it’s 13.5%.• Tacking in your consideration the number of green building already constructed and renovated throw these years, you could find clearly that our consumption is rising.
  7. 7. Why should we work on saving water?• According to the EPA’s Water Sense Program, while the U.S. population increased 90% from 1950 to 2000, the demand of water increased 209%. Water Cube Beijing Olympics 2008 Venue images
  8. 8. Why should we work on saving water? 2- the water availability: • Even though 70% of the Earth’s surface is covered with water, most of that (97%) is salt water, 2% is frozen in glaciers and ice caps, leaving only 1% for human consumption.*U.S. Geological Survey and Water Sense.
  9. 9. • Why should we work on water saving?• How could we save water in the Sustainable Buildings?• How much water saving percent could we reach?
  10. 10. How could we save water in the SustainableBuilding?• Specify more water efficient appliances.• Address alternative source of water that can help satisfy the needs.
  11. 11. How could we save water in the SustainableBuilding?water efficient appliances :Faucet:1- Aerator Faucet:• The standard flow rate of lavatory and kitchen faucet models are 2.2gpm (Gallons per minute)• the most common aerators run with 1.5gpm.• resulting in over 30% water saving. While some aerators run as low as 0.5gpm, resulting in more than 75%.
  12. 12. How could we save water in the SustainableBuilding?water efficient appliances :Faucet:2- Metered faucet:• Offer adjustable cycle times resulting in a range of 1.3 USGPM down to 0.08USGPM per cycle.• Results in a 48% to 68% saving.• reassure that your faucet won’t be left running.
  13. 13. How could we save water in the SustainableBuilding?water efficient appliances :Faucet:3-Foot-pedal activated:• Easier for users to turn on/off the water with dirty or soapy hands.• Reduce water waste.• Leading to 30% or greater water reduction.
  14. 14. How could we save water in the Sustainable Building? Water applications:Shower:• EPACT’92 Government mandated flow levels are at 2.5gpm.• For low-flow showerheads, typically range from 1.5gpm to 2.0gpm.• Presents a 20-40% water saving. The key to success with low-flow showerheads, is not only using less water, but providing the same -or better- user experience.
  15. 15. How could we save water in the SustainableBuilding?Water applications:Toilets:• Toilet technologies use the pressure built up in the water supply lines to help complete the flush by pushing water out, rather than pulling it in a gravity system.• This provides the same function while using less water.
  16. 16. How could we save water in the SustainableBuilding?Water applications:Toilets:• Dual-flush toilets are provide two flush levels, a full flush using 1.6gpf, and a partial flush using only 0.8gpf.• water saving can easily exceed 20% or more.
  17. 17. How could we save water in the SustainableBuilding?water efficient appliances :Urinals:• New waterless urinals.• This system use a replaceable canister sealed with fluid sealer.
  18. 18. How could we save water in the SustainableBuilding?water efficient appliances :Irrigation:• Using native species of plants, gives us the magnitude opportunity to minimize the need for irrigation.• Installing high-efficiency irrigation systems like smart weather-based irrigation controllers.
  19. 19. How could we save water in the SustainableBuilding?Alternative sources of water:Reusing Grey water:• This water can be collected using separate drain lines.• Filtered to remove large particles.• Stored and then distributed to application systems.
  20. 20. How could we save water in the SustainableBuilding?Alternative sources of water:Reusing Grey water:• 99% of the house holds sewage is water.• These 99% divided as 40% from toilets, 30% from bath, 15% from laundry, 10% kitchen, and 5% miscellaneous.• Obviously, 30% water from the bath + 15% water from the laundry, are more than the 40% water needed for toilet.
  21. 21. How could we save water in the SustainableBuilding?Alternative sources of water: Capturing Air-Conditioning Condensation:• Air-conditioning condensate is essentially distilled water, it is very pure when first produced,• But bacteria and other contaminants can collect in the piping and storage vessels.• Therefore some form of treatment is typically provided even for non-potable uses.
  22. 22. How could we save water in the SustainableBuilding?Alternative sources of water:Rainwater Harvesting:• Rainwater is commonly used as a source of non-potable water for landscape irrigation, cooling tower makeup, and for toilet flushing.• While provide the sole source of water for buildings in some locations such as: Volcano- Hawaii, and the U.S. Virgin Islands.
  23. 23. How could we save water in the Sustainable Building?Conclusion:• High-efficient and/or waterless appliances.• Native species of plants.• Grey-water use.• Captured condensation water.• Rain-water harvesting.
  24. 24. • Why should we work on water saving?• How could we save water in the Sustainable Buildings?• How much percent of water saving could we reach?
  25. 25. How much percent of water saving could we reach?
  26. 26. How much percent of water saving could we reach?About SFS• Middle School building with LEED platinum certification.• 93% less of the Districts water supply is used by treating sewage on site in constructed wetland and reusing the water in toilets and cooling-tower.• Green-roof sequester rainwater and reduce storm water runoff, students grow vegetables and herbs for the cafeteria there.• Landscape plant species are drought resistant and able to thrive naturally in local area (No potable water used for irrigation).Designed by architect KieranTimberlake Associates and landscape design by Andropogon Associates.http://www.sidwell.edu/green_tour/index.aspx
