1. In this presentation we will see some things about.. Water needs Energy needs Drawings Materials’ choice Façade

3. 2.389 m3/ res. consumption per year in Greece 6,55 m3/res. per day

5. 0,18 m3 average daily consumption

6. AVERAGE WATER CONSUMPTION BY RESIDENTIAL USERS / 4 MONTHS (source ΕΥΑΘ) 39,0 m3 35,4 m3 34,3 m3 33,7 m3 2007 32,7 m3

7. SWRO sea water reverse osmosis Ashkelon SWRO plant , Israel The largest project in the world Plant footprint 75.000 m2 (300m x x250m) Max electrical consumption <4 kWh per m3 product water Final total production capacity 108 million m3/yr Contribution to national demand 5-6% total GE general electric company POWER & WATER SeaPro, SeaPro-E series Flow rates: 100-2.500 m3/day SeaTech series Flow rates: 163-3.000 m3/day Both previous platforms are small- medium sized Small- medium sized plants produce <10 to 20.000 m3/day

8. This is what a big-scale installation looks like.. ..and here is the main machine, the ultrafiltration membranes

12. 100 L/day for others uses (washing hands, tidy the pavillion, …)Production of the SWRO system : 1 m3/day (with a maximal electric consumption of 4 kWh per m3 product water)

13. Rain water recovery : A wall which gathers the roof rain water

15. 4,5 kW/day for the activity of the pressing pomp for the osmose reversionProduction of photovoltaic installation: 7,5 kW/day Considering the solar pannels are exposed south-west, inclination perpendicular to the sunrays, and shadow 0%: 25 m2 of solars needs are enough for produce 7,5 kW/day.
