REVERSE BRICK VENEER WALLS WITH WEATHERBOARD EXTERNAL CLADDING HAS BEEN CHOSEN AND SELECTED AS THE PRIMARY EXTERNAL WALL TYPE, IN ORDER TO PROVIDE THE HIGHEST QUALITY OF INSULATION AGAINST MELBOURNE’S ZONE 6 CLIMATE.

*UNDERCOVER AREA IS SHADED BY DECIDUOUS VINES GROWN ON PERGOLAS. IT ACTS AS SHADING DURING SUMMER, BUT NOT WINTER.

WATER TANK

- EXTRACTS HEAT FROM THE AIR AND TRANSFERS THIS HEAT TO THE WATER - USES ELECTRICITY, SO IT CAN BE POWERED BY SOLAR ENERGY - 1/3 THE ENERGY OF AN ELECTRIC WATER HEATER - VERY EFFICIENT AS THE AMOUNT OF ENERGY EXTRACTED FROM THE AIR IS MORE THAN THE AMOUNT OF ENERGY USED TO EXTRACT IT

RAIN WATER FOR THIS HOUSE IS COLLECTED OFF THE PITCHED GABLE ROOFS AND INTO THE EAVE GUTTERS, WHERE IT THEN FLOWS INTO THE GUTTER DOWNPIPES WITH MESH (THE MESH HELPS TO CONTROL AND REMOVE SEDIMENTS THAT MAY HAVE BEEN PICKED UP ALONG THE WAY).

UNDER GROUND WATER TANK 5000L (2300x2890x1265)

THE RAIN WATER COLLECTION SYSTEM SELECTED IS A WET SYSTEM AS RAIN CAN BE COLLECTED FROM BOTH SIDES OF THE ROOF, AND AS NEW RAIN WATER IS COLLECTED, THE ALREADY EXISTING RAIN WATER WITHIN THE PIPES IS PUSHED ALONG AND INTO THE WATER TANKS. FINALLY, SINCE RAINFALL IS NEVER REALLY CONSTANT, RAIN WATER IS NOT USED AS A PRIMARY WATER SOURCE, AND MORE IS MORE SO SECONDARY. IT CAN BE USED FOR APPLICATIONS SUCH AS TOILET FLUSHING WHEN RAIN WATER IS AVAILABLE, AND WHEN NOT, NORMAL POTABLE WATER IS USED. HIGH LEVELS OF RAIN WATER CAN ALSO BE CHANELLED AWAY AS EXCESS OVERFLOW.

A POND HAS BEEN PLACED ON THE SOUTHERN END OF THE PROPERTY TO FUNCTION AS A STORM WATER CATCHMENT SYSTEM. THIS LANDSCAPE CHOICE WAS MADE BY ANALYSING THE CURRENT PROPERTY’S TOPOGRAPHY, WHICH SUGGESTED THAT RAIN WATER FLOWING ON THE LANDSCAPE WOULD ALREADY NATURALLY COLLECT AT THAT PARTICULAR POINT; THE LOCATION OF THE STORM WATER POND (REFER TO ‘SITE PLAN’ DRAWING FOR MORE LANDSCAPE TOPOGRAPHY INFORMATION). THE COLLECTED STORM WATER CAN WITH A PUMP SYSTEM BE REUSED FOR GARDENING.

GIVEN THE HIGH QUALITY OF PASSIVE DESIGN WITHIN THE HOUSE, HEATING AND COOLING WOULD BE MINIMALLY REQUIRED AS IT SHOULD ALREADY BE COMFORTABLE. WITH THIS IN MIND, AS WELL AS THE CLIENT’S PRESENCE AND USE WITHIN THE HOUSE, MULTI-SPLIT SYSTEM REVERSE CYCLE AIR-CONDITIONING WOULD BE INSTALLED THROUGHOUT PARTICULAR AREAS FOR SHORT-TERM HEATING AND COOLING USE.

IN THE DESIGNED HOUSEHOLD, TWO GREY WATER SYSTEMS ARE INSTALLED ON OPPOSITE ENDS OF THE HOUSE IN ORDER TO COLLECT AND HARVEST THE GREY WATER GENERATED FROM BOTH BATHROOMS. THE COLLECTED GREY WATER FROM SHOWER AND BATH USE, AS WELL AS LAUNDRY AND WASHING SINKS (EXCLUDING THE KITCHEN SINK) ARE THEN CONVENIENTLY USED FOR GARDENING ON BOTH SIDES OF THE HOUSE. AN IMPORTANT PROCESS HOWEVER DOES OCCUR BEFORE THE GREY WATER CAN BE USED FOR GARDENING. THIS IS THE PROCESS OF FILTERING AND TREATING THE GREY WATER TO AN APPROPRIATE CONDITION. THIS CAN BE ACHIEVED VIA SEVERAL DIFFERENT METHODS, SUCH AS THROUGH A SYSTEM LIKE THE “GECKO”; WHICH IS INSTALLED IN THE HOUSE (SHOWN BELOW).

ASSIGNMENT 1 RESILIENT DESIGN

GREEN ROOFS

RESILIENCE IS ABOUT NOT ONLY SURVIVING, ADAPTING AND RECOVERING FROM ADVERT EVENTS AND ADVERSITY SUCH AS CLIMATIC ONES (FLOODS, DROUGHTS, HURRICANES ETC.) OR EVERYDAY STRESSES, ILLNESSES AND CONFLICTS, BUT BEING ABLE TO GROW FROM SUCH EVENTS TO BETTER DEAL WITH THEM IN THE FUTURE. THIS IS WHERE RESILIENT DESIGN GROWS AND STEMS FROM.

THEY ARE A MEANS OF PROVIDING GREEN SPACES WHERE IT HAS BEEN LOST; WHICH IS WHAT IS HAPPENING A LOT IN TODAY’S MODERN SOCIETY OF GROWTH. LANDS OF NATURE AND GREENERY ARE BEING REMOVED ONLY TO BE REPLACED BY NON-PERMEABLE SURFACES AND INFRASTRUCTURE THAT MAINLY NEGATIVELY IMPACT OUR ENVIRONMENT BY ENHANCING THE ‘URBAN HEAT ISLAND EFFECT’, AS WELL AS BRING PROBLEMS SUCH AS WATER RUNOFF ABOUT.

WHAT IS RESILIENCE? WHAT IS RESILIENT DESIGN?

RESILIENT DESIGN IN THE CASE OF BUILDINGS AND HOUSEHOLDS IS DESIGNING TO NOT ONLY COMBAT, BUT TO WITHSTAND SUCH ADVERSITIES, WHILST PROVIDING THE BEST CONDITIONS AND CHANCES OF SURVIVAL. THIS ESSENTIALLY MEANS HOW WELL AND COMFORTABLE A DESIGNED HOUSE OR BUILDING CAN REMAIN LIVEABLE, WHEN SURROUNDING CONDITIONS TURN UNFAVORABLE AND SOUR. WITH THE FUTURE BEING SO UNPREDICTABLE, AND THE POSSIBILITIES AND CHANCES OF ADVERT EVENTS ALWAYS BEING A POSSIBILITY, WE AS HUMANS AND SOCIETIES CANNOT AVOID SUCH EVENTS, BUT ONLY BE AS BEST PREPARED FOR IT WHEN IT OCCURS, AND PROVIDE OURSELVES WITH THE BEST CHANCE OF SURVIVING AND OVERCOMING THE PROBLEM. WITH THE NEED AND IMPORTANCE OF BEING PREPARED FOR SUCH EVENTS CONSTANTLY GROWING, RESILIENT DESIGN AS A VERY IMPORTANT DESIGN CONSIDERATION THAT SHOULDN’T BE OVERLOOKED. WITHOUT RESILIENT DESIGNING, EVEN THE MOST SUSTAINABLE DESIGNS MAY NOT NECESSARILY SURVIVE WHEN ADVERT EVENTS OCCUR. AND IF THATS THE CASE, WHERES THE SIGNIFICANCE OR USE OF THE ‘NO LONGER EXISTING’ SUPER SUSTAINABLE DESIGN?

GREEN ROOFS IS AN INNOVATIVE EXAMPLE OF URBAN GREEN INFRASTRUCTURE THAT CAN BE IMPLEMENTED WITHIN SOCIETY TO NOT ONLY ENCOURAGE AND IMPROVE THE SUSTAINABLE QUALITIES OF A CITY, BUT ALSO THE QUALITY OF LIFE.

GREEN ROOFS ARE A POTENTIAL SOLUTION TO THESE PROBLEMS, AND IF NOT, CAN CERTAINLY PLAY A PART IN MINIMISING THEM. SOME OF THE BENEFITS OF GREEN ROOFS INCLUDE: - INCREASING PROPERTY VALUE - INFLUENCING STORM WATER MANAGEMENT AND ROOF WATER RUN OFF - IMPROVING THE THERMAL AND ACOUSTIC PERFORMANCES OF ROOFS - PARTAKES IN THE PRESERVATION OF NATURAL HABITATS - REDUCING THE “URBAN HEAT ISLAND EFFECT” - CAN BE AN AESTHETIC ENHANCER - AND CLEANING THE ATMOSPHERE AND AIR GREEN ROOFS ARE ESSENTIALLY AND CAN BE A VERY BENEFICIAL ADDITION TO ANY HOUSEHOLD OR BUILDING, AND HOPEFULLY IT HAS MANY MORE POSSIBILITIES WAITING TO BE DISCOVERED OR IMPROVED UPON, IN THE FUTURE.

THE DIFFERENT TYPES OF GREEN ROOFS

THE DIFFERENT TYPES OF GREEN ROOFS ARE GENERALLY DIFFERENTIATED BY THE LAYERS THE GREEN ROOF ITSELF IS COMPOSED OF; ESPECIALLY THE SUBSTRATE LAYER. THIS DIFFERENCE IN LAYERS ALSO SUBSEQUENTLY INFLUENCES THE FUNCTIONS OF EACH PATICULAR TYPE OF GREEN ROOF. THE TWO MAIN TYPES OF GREEN ROOFS INCLUDE: 1.INTENSIVE GREEN ROOFS - SUBSTRATE GREATER THAN 30CM - ACCESSIBLE - REQUIRES MAINTENANCE - GREATEST POTENTIAL OF DESIGN AND PLANT DIVERSITY - MOST EXPENSIVE - BEST INSULATION AND WATER MANAGEMENT - REQUIRES A SUFFICIENT AND STRONG ROOF AS SUPPORT 2. EXTENSIVE GREEN ROOFS - SUBSTRATE LESS THAN 20 CM - NOT ACCESSIBLE - LOW MAINTENNACE - LIGHTWEIGHT - SUITABLE FOR RETROFIT
