BUILDING SYSTEMS

NZE STRATEGY: RENEWABLE SYSTEMSo ANNUAL ENERGY GENERATED = ENERGY DEMAND

o SOLAR PHOTOVOLTAIC POWER GENERATION (APPROX. 200 KW ARRAY)

NZE STRATEGY: ACTIVE SYSTEMSo RADIANT HEATING AND COOLING EMBEDDED IN THE SLAB

o AIR SOURCE HEAT PUMPS (NO COMBUSTION) TO HEAT HOT WATER FOR BOTH

DOMESTIC WATER AND RADIANT SLAB USE

o OPTIMIZED CONTROLS

o CONVENTIONAL VAV SYSTEM FOR PEAK CONDITIONS

NZE STRATEGY: PASSIVE SYSTEMS o HIGH PERFORMANCE GLAZING TO MINIMIZE SOLAR GAIN

o WEATHER STATION FOR OPTIMIZED CONTROLS WITH AUTOMATED NATURAL

VENTILATION

o DAY LIGHTING CONTROLS

o EXPANDED COMFORT CRITERIA (70 TO 78°F)

o LOCALIZED CONTROL WITH DESK FANS AND OPERABLE WINDOWS

BUILDING SYSTEMS

NZW STRATEGY: RAIN TO POTABLE

o RAINWATER TO BE COLLECTED FROM NSF CERTIFIED ROOF AND PV CANOPY

o STATE WATER RESOURCES CONTROL BOARD – DIVISION OF DRINKING WATER (DDW) TO PERMIT

o FOOD GRADE ROOFING AND COMPONENTS WILL BE USED THROUGHOUT

o TESTING TO BE CONDUCTED BY DDW STANDARDS

GREY WATER RECYCLING

o GREY WATER FROM SHOWERS AND LAVATORIES TO BE CAPTURED AND TREATED TO NSF 350

STANDARDS

o WORKED WITH LA COUNTY HEALTH DEPARTMENT TO PERMIT

o IRRIGATION DEMAND TO BE MET FROM RECYCLED GREY WATER

NZW STRATEGY: DROUGHT CONDITIONS

o IN TIMES OF DROUGHT, THE SYSTEM WILL BE TOPPED UP WITH WELL WATER
