Usually, living areas and the kitchen are the most important locations for passive heating as they are used day and evening. Bedrooms generally require less heating.
SITE LOCATION Williamstown is a suburb of Melbourne, Victoria, Australia, 9 km (5.6 mi) south-west of Melbourne's central business district in the local government area of the City of Hobsons Bay.
Willamstown
Additionally, it allows cool summer winds from south to enter the house so that the internal spaces will be cooled down passively without much extra energies. Melbourne has a temperate oceanic climate with changeable weather conditions. Thus to respond the design, multiple heating and cooling system might be necessary to react to different solutions. A wellinsulated structure of house is essential, too.

Deciduous Trees: Jacaranda loses it leaves in autumn and provides winter sun. Magnolia is a spring-flowering tree. Deciduous Vines: Wisteria grows well in temperate climates of cooler places to the south in Australia and it does like a somewhat sheltered position in full sun. It may take a good few years for a newly established wisteria to start flowering but the vine itself can grow three metres or more in a year.
DEPTH OF EAVES As a rule of thumb, eaves width should be 45% of the height from the window sill to the bottom of the eaves. 45% rule of thumb for latitudes south of and including 27.5°S.
LEGEND OF PASSIVE DESIGN Sun Radiation（Weaken through Tree） Natural Ventilation Direction
STACK VENTILATION AND ROOF Openings can be strategically designed to allow the heat to escape. High openings and outlets provide structural cooling. In a single-storey house, clerestory windows allow hot air to escape and thus generate circulation. In addition, Natural ventilation lowers cooling and ventilation costs, as well as providing a close connection with the outside environment. Furthermore, natural ventilation systems help to eliminate noise created by fans potentially increasing acoustic comfort.

The choice of roof is clerestory which allows allows passive cooling and heating techniques, uses natural light for daylighting and maintains some privacy. The angle of roof is 37.8, which is equal to the latitude angle of the location of the property, with the solar panels mounted at the same angle as the roof. Because Solar panels generate maximum power when they are positioned perpendicular to the sun. Solar power yields are higher when panels face north.

It has been emphasized for several times that the primary goal for EBS is the occupants’ comfort, sustainability is secondary. The selection criteria for lamp choices in this design will not only involve efficiencies but also human comfort and psychology; warm and white colours would be used interchangeably through out rooms and spaces. Although LED is catching up, the most efficient and economic lamp to buy at the moment is still CFL. However, according to people’s experience, CFL feels cold and lacks a sense of welcoming. Therefore, after comprehensive consideration, LED lamps will be used in this design. To keep in mind, it is more difficult to choose a suitable LED lamp, as different product’s efficiency can vary from 20 to 40 Lumens per Watt.

The design of this house seeks to eliminate the use of gas services due to a number of reasons: 1.
2. 3. 4.
A cheaper and more sustainable solution for electricity generation will soon be found. Reduce the number of services; simplify the service networks. Eliminate any potential hazards if gas meets electricity. Minus one type of energy bills.
The heating and cooling services only involve the use of electricity and water in this household; all appliances are powered by the same types of energy services.
Rainwater is now an essential feature in sustainable design. Rainwater harvesting (RWH) is one of the traditional and most effective method to maintain the balance between water demand and supply. RWH is affordable, low-tech and can be implemented to every unit dwelling. It is not only environmental & social – friendly because it reduces pressure on mains’ supply but it is also economically friendly as it significantly reduces a household’s water bill. It is a simple and effective technique that is helpful to maintain the balance between environment and economics; a pair usually considered hostile to each other.
The rainwater tank is only a means for storage. Before rainwater enters, it is filtered by several steps. 1st: leaf guard/gutter mesh. 2nd: Rain heads. To keep out insects. 3rd: First Flush Diverter. 4th: the tank is secured by insect proof screens to prevent mosquitoes. To use the water from tank, a pump-filter system needs to be installed; as shown in the plan.

3. Water Supply & Collection
Grey water system: Grey water is the used water produced from SHOWER, BATHS, HANDBASINS, WASHING MACHINES.Etc. which can be recycled to fulfil part of household’s water demand, for example: garden watering & car washing in most cases. In this design, we care about the environment as well as your bills, hence we value the opportunities brought by a good grey water treatment system which would save your total water bill by up to 30%! However, it must be noted that the waste water produced from kitchen sinks and the blackwater produced from toilets require a much different and higher level of water treatment technology. Recycling them could ultimately result in 100% water reuse but it would also cost between $10,000 - $20,000 and storage and absorption trenches can take a large amount of spaces on site. A septic system is generally unnecessary for a household living in non-rural areas.

Sewerage system: In this project, the consideration of sewerage system is left to the last because we wanted to maximise our effort to save and recycle water; exploiting every last bit of its feasible value before dumping anything to the waste.
As illustrated from the diagram, the use of grey water is a process of extracting them from inside to the outside, then processed and used on the outside. Because it has little to do with anything inside the house, the pipework is externalized instead of installed inside the wall. Also, in this way, any repair becomes relatively more convenient.
Within the chosen Grey Water Treatment – “Grey water Gator Pro”, several stages of treatment are involved to provide a safe and affordable greywater recycling experience: 1.
2. 3.
Filtration of solids – the heterogeneous substances in greywater is first being filtered by the Unique Progressive 3-D Filter Technology developed by Gator Pro. Removal of Pathogens and unwanted chemicals – The Gator Pro uses chemical treatment to remove pathogens quickly and effectively. Disinfection – Done by Chlorination.
The system also comes with a pump so that it includes everything a household needs from greywater to garden irrigation and car-washing water.
STUDENT NAME: AIYANG JIANG STUDENT NUMBER: 877726
Considering all the available greywater is being recycled in this household, there are only 3 non-recyclable wastewater sources left: two toilets and a kitchen sink. Precaution is taken as the pipe-work of sewerage system is different to other pipes. 1. There are no right angles in the network; preventing any potential blockage from happening. 2. The gradient of the pipes must be 1:200. The system completely relies on the effect of gravity. 3. The pipes must be vented otherwise the smell will infiltrate into the rooms.

Heat Pumps are the workhorse of the Tivok Energy Thermal System. Heat Pumps utilise the heat energy in the air to heat water at an energy efficiency greater than 4 times*1 that of conventional electric or gas heaters.
HYDRONIC SYSTEMS The main heating systems chosen for the house are combination of hydronic in-slab heating and hydronic panels heaters. In this design, hydronic systems are heated by heat pump. The system is zoned available among living areas, kitchen and each bedroom in order to speed up the heating and make good use of energy. The hydronic system is connected with the thermostants so that the problem of requiring time to heat up can be solved. The hydronic in-slab heating system is used in living area and kitchen while the hydronic panels are used in bedrooms. Living/Kitchen is separated into 2 coils as it provides higher energy efficiency and higher heating speed compare to one large coil. The client is also unlikely to occupy both living and dinning space at the same time, hence 2 separated coil reduces energy wastes.

Hydronic Cooling System As mentioned before, the hydronic system is already used for heating. The clients already shelled out a premium price for a hydronic system thus the system can be better used. Hydronic cooling system and technology can provide comfortable and efficient cooling. Just as water is effective at conducting heat, so too can it effectively convey cooling. Zone control installation is necessary to allow to set different temperatures throughout the home, and only cool the rooms while using. Water Discharge On Roof To Gutter For Stormwater
EVAPORATIVE COOLER
The main system chosen for cooling is the Evaporative cooler. Evaporative cooler is effective for hot dry days to against the extreme heat days in Melbourne. The evaporative system is zoned among living areas, kitchen, dining as well as bedroom zone which lowers running costs as you only cool the areas that you're using.
Breezair TBA 550 Type Breezair TBA 550 Type
Here are some advantages: - It’s also cost effective because it only cost energy to run the fan inside and the costs of water. - The evaporative process relies on airflow, the circulating air is 100% fresh. The air is also filtered by cooling pads. - The evaporative air conditioning systems use moisture to cool the air and won’t dry your skin, which is a comfortable system compare to dry air from refrigerated air conditioners - Ducted evaporative cooling units require windows or doors to be open to create airflow, thus it can also be used for cooling outdoor areas
Underfloor is another option for hydronic cooling. This works by circulating cooled water through the underfloor pipes, which then absorbs the heat from the rooms. Because there are no fans or vents, the result is an even distribution of temperature, and no drafts.
Physics Principle
Thermal radiation travels at the speed of light, in straight lines. Heat will flow from objects, occupants, equipment, and lights in a space to a cooled surface as long as their temperatures are warmer than that of the cooled surface. Some heat is also removed by convection because the air temperature will be lowered when air comes in contact with the cooled surface.
This super-insulated residential EBS design focuses on minimising heat transfer; preventing rooms from heating up during summer. We are confident that in most summer days, the building envelop is able to resist heat penetration and maintain a cool internal space through out the day. However we have not left out active cooling because we had also taken into account the extreme hot days, the possibility for extreme heat waves to occur, or the possibility that the building is not as well insulated as we have designed after construction. The This design offers a variety of cooling strategies. 1. Fan. The fan does not really produce cool air, or absorb heat. It uses minimal amount of electricity to significantly increase the effectiveness of natural ventilation (passive design). 2. Hydronic System. Although the hydronic system does not usually compete as a cooling system in the market, it could still provide an effective cooling effect during summer. It simply works in a reversed way compared to heating mode. 3. Evaporative cooler. It is the most intended cooling system in this design, it exists to accommodate the worst situation when extremely hot and dry days occur and all the rest of the design fails to cool.

Working Principle Of Evaporative Coolerc
Thermostant Based on the simple principles of evaporation, as the air blows through the cooling pads, the water is evaporated and the heat in the air is absorbed, which lowers the air temperature. A fan then pushes the cool air through the ducting system. Breezair cooling units feature a patented centrifugal fan, which can be used in fan only mode (no water) to blow fresh air through home.
Ceiling fan is chosen as an option of cooling when evaporative cooler not works very well in hot humid days. Fan doesn’t reduce pressure or cool air in the space, but the air movement increase the comfort as the skin evaporate better. The breeze created by a ceiling fan speeds the evaporation of sweat on human skin, which

DESIGN RESILIENCE STRATEGIES An efficient fridge is a better choice for saving energy and best energy star rating
Evaporative Cooler uses a lot of water
Unappropriate electrical choices might against client’s requirements when function off-grid or disaster with little energy / resources usage
CLIENTS’ WORRIES: Electricity Grid May Failed
The advantages of a green roof are various.
-
— They help improve energy efficiency — They also reduce the local rainwater systems’ pressure as well as rainwater runoff by retaining and withholding rainfall — Green roofs counter the urban heat island effect by lowering temperatures and improving local air quality. — They also offer greater biodiversity integrated with the natural environment
Heatwaves Peak electricity loads during heatwaves Fires destroying power lines Wars and terrorism
CLIENTS’ NEEDS: Function off-grid with little energy usage
STRATEGY 1: BUNKER
E.g. Clients need onsite power generation.
Insufficient back-up strategy to accommodate the worst blackout scenarios such as extreme heat waves, terrorist attack. Etc.

As the requirements of clients, a bunker would be a very useful addition for following functions: - AGAINST HEATWAVE - FIRE SAFETY ESCAPE - SURVIVAL EARTH-SHELTER WHEN WARS / TERRORISM The underground temperature of Melbourne under 1m is aprroximately 16~18℃, so the room would always be the similar temperature.
STRATEGY 2: ON-SITE GENERATOR
A Tesla Powerwall can provide electricity A green roof is designed for rainwater filter, extra heat insulation, reduced heating & cooling requirements Install a on-site generator - the secondary power insurance policy when Tesla Powerwall fails to provide electricity （Inside the bunker). Build a bunker in order to provide a safe place for fire safety problem,wars, terrorism as well as the area suffers from heatwave.
