Sustainability
Solar Panels Solar panels convert sunlight into clean green DC electricity
Green Roof Section Benefits -reduce a community’s urban footprint -increase a building’s marketability -greater insulation offered by green roofs can reduce the amount of energy needed to moderate the temperature of a building -noise and sound insulation -water is stored by the substrate and then taken up by the plants from where it is returned to the atmosphere through transpiration and evaporation
Reusing Non-potable Water Determing a Cistern Tank Size - # of people in the building - average #of flushes per person - approximate amount of gallons per flush
Collecting the Water .4 x precipitation in in. (yearly) x area of roof in sq. ft.= gallons harvested yearly
Supply authority power grid During peak periods and at night electricity is imported from the grid
Inverter converts DC electricity into useable AC electricity
Existing electrical switchboard with new bi-directional metering installed Exported electricity- when the solar system generates more electricity than your household uses the excess electricity goes back into the grid and spins your meter backwards adding credit to your electricity bill
Ideal Placement
1. South 2. Southwest 3. West
Recycled water to house Garden and carwashing
Process lines from control box Greywater from bathroom to laundry Overflow to sewer
Toilet and kitchen to sewer
1. Know your electricity Usage 2. Measure roof area that faces S, SW and W 3. Calculate how many solar panels will fit. roof area/16= # of solar panels that fit 4. Calculate what size panels are needed array size/ # of panels that can fit= amount of kW/panel
