In this presentation we will see some things about.. Water needs Energy needs Drawings Materials’ choice Façade
Average consumption in Greece 180 Ll/res.d.
2.389 m3/ res. consumption per year in Greece 6,55 m3/res. per day
We could need only 80 Ll/res.d. or less with a change of habits
And the use of simple technologies of saving water
1 m3 = 1.000 Ll
0,18 m3 average daily consumption
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
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
This is what a big-scale installation looks like.. ..and here is the main machine, the ultrafiltration membranes
Water pressure variation: when coming in, filtrating, coming out
However what we propose is a brand new idea, since the pavilion will be self sustained and cover only its own needs. All known examples of SWRO so far are plants that produce and sell water. We re-size these facilities and adjust them at the scale of the pavilion.
The SWRO system and the consumption of the pavillon Consumption of the pavillon : 1 m3/day With:
900 L/day for toilets ( estimated 100 persons/day with 1 use = 9 liters)
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)
Rain water recovery : A wall which gathers the roof rain water
Energy needs Consumption of the pavillion: 7,5 kW/day
3 kWh/day for lightening ( 50 LED of 4 Wph inside the building open 5 h/day, and 50 LED of 4 Wph on the tentacules open 10 hours/day)
4,5 kW/day for the activity of the pressing pomp for the osmose reversion
Production 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.
