  3. 3. Renewable Energy  Renewable energy is energy generated from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished)  Generate carbon free energy and are also clean and pollution free  also referred to as "pollution free power" technologies Renewable Technologies Solar Wind Hydro Tidal Ocean Biomass Waveenergy energy energy energy Geothermal thermal energy energy

  5. 5. Water Treatment/Conservation Products with the water treatment/conservation feature either increase the quality of water or reduce the amount of water used on a site. This can be accomplished in two ways: by physically restricting the amount of water that can pass through a fixture (showerhead, faucet, toilet) or by recycling water that has already entered the site.
  6. 6. Water Efficient AppliancesAny appliance which uses significantly less water than a standard fitting.Such as: Water Efficient Appliances/ Fixtures
  7. 7. Waterless Urinals Resemble conventional fixtures Easily replace them Eliminate flush water supply lines Flush valves are completely eliminated No handles to touch, no sensors to install or adjust Daily cleaning procedures are the same as for flushed urinals.Benefits: cost savings reducing the problem of water shortages reducing the energy required to treat water reducing the amount of water that flows into sewers The costs of installing these products are comparable to standard fittings.
  8. 8. Water saving shower heads Shower accounts for about 30 % of the total household water consumption A reduced shower head flow rate will reduce water consumption during bathing, without sacrificing user satisfaction
  9. 9. Water saving faucets Reduced faucet flow rates can still reduce overall domestic water consumption, water heating demands, and wastewater treatment loads. High-efficiency faucets in the bathroom or a faucet aerator can reduce water flow by as much as 30% without significantly reducing performance.
  10. 10. Water saving washing machines Automatic clothes washing machines account for about 20% of the total volume of water consumed in residents Savings in water usage for these devices may come from different loading positions, suds-saver options, water level settings, and design.
  11. 11. Rainwater Harvesting A system which collects rainwater from the roof of a building and stores it for reuse. This reduces water requirements from the mains supply. Water collected is then stored in a tank, before being pumped around the building, as and when required. This water is not suitable for drinking purposes but is used for other purposes such as flushing toilets and for washing machines.
  12. 12. Benefits: Reduces the demand for treated mains water by up to 50% Sustainable drainage Reducing the demands on water treatment plants.
  13. 13. Grey water recycling Any water that has been used in a building, except water from toilets, is called grey water. Dish, shower, sink, and laundry water comprise 50-80% of residential waste water. This may be reused for other purposes, especially landscape irrigation.Benefits: Lower fresh water use Groundwater recharge Plant growth Reclamation of otherwise wasted nutrients.
