The existing rainwater cistern
will be complemented by a second one, which will ensure an environmentally friendly water supply.
A six-story building ruing solar panels, a rainwater cistern
, composting toilets and a constellation of other systems to achieve what might be the most arduous certification process in sustainable building today.
To make the building more water efficient, the bathrooms are equipped with dualflush toilets, sink sensors and a rainwater cistern
to supplement irrigation and toilet flushing, which also helps the building reduce water use by 30 percent.
Schooner Bay will have many "green" features, such as wastewater treatment, a community rainwater cistern
, rooftop cisterns and a recycling center.
The work is illustrated with photos of a single project as it develops from start to finish and contains advice on design, breaking ground, installing a rainwater cistern
, using adobe, straw bale walls, the electrical system, windows and insulation, earth plaster, and finish work.
for irrigation, a geothermal heating/cooling system, and passive-solar design.
Mr Marasco said that some of the sustainable design strategies applied included; the use of recycled, locally sourced and low-emitting building materials; drought resistant planting with a rainwater cistern
for partial landscape irrigation; a heat recovery system; occupancy and daylighting sensors and a combination white reflective/green roof system.
The design incorporates a garden roof area connected to the adjacent science classroom; a comprehensive stormwater management plan that includes an underground rainwater cistern
that supplies water to the toilet fixtures and cooling tower, pervious pavers, and porous playground surfaces; and carefully designed windows, tubular skylights, and light shelves to both maximize daylight in classrooms and reduce the energy spent for lighting.
A rainwater cistern
provides all the water necessary for landscaped areas that feature native and drought tolerant plants thereby eliminating the need for municipal water for irrigation saving natural resources and the homeowner's money.
Though PACE financing is widely recognized as a mechanism for funding residential solar power, Ygrene Works PACE financing also offers funding for: rainwater cisterns
, water saving sprinkler system, drip irrigation, artificial turf and low flow plumbing.
Underground rainwater cisterns

Two towering rainwater cisterns
capture rainwater used to hydrate garden areas during dry spells and conserve the overall water flow.
