Client Profile
Site Analysis The wind rose diagram on the left hand side indicates Melbourne mainly benefits from cool south-west breeze, which can be taken fully advantage of in passive ventilation.
Our clients are a family consisting of a young couple and two little kids: one 3 years old, the other 5 years old. They are interested to have a sustainable new house where they would probably stay for more than 10 years. They have the following habits & requirements:
blackwater & waste to sewer drainage water tank under timber decking & underground
- adequate natural light - be self-surfficient in many aspects, for example, energy, food harvesting... so reducing living expense - the family love to gather together in the living space - both the young couple work in office all day long, kids sent to kindergarden, so no ppl during daytime. - usually taking shower before sleep
The second diagram on the left hand side indicates summer and winter sun path. Both of them are from north, so we will have living space facing north. The summer sun has higher angle, which should be blocked by shading, roof design.
greywater overflow to LPD Tesla Battery to electric meter to the grid Telcom system to telecom pit
There is a single-storey house on the left hand side of the property, and two double-storeis houses on the right hand side. With a minimum distance of 6 meter from the former, and 11meters from the latter, we can determine the location of the project.

Compared to the common â&#x20AC;&#x2DC;slab-ongroundâ&#x20AC;&#x2122; foundation, the Cupolex void foundation system is a better choice because it will neither crack with moisture change in soil and nor produce unhealthy indoor environement with revealing VOC (volatile organic compounds). It also reduces the consumption of cast concrete and rebar, but performs same durability. It also allows service pipe to run through slab. The chosen profiles are manufactured locally and can be recycled, which means less embodied energy.
The insulated reverse brick veneer system is applied to all the external walls, which largely improves the thermal performance of the building envelop. The external timber claddings are treated for termite prevention.

In the north-facing living/kitchen space, polished concrete is used for flooring due to passive thermal performance and aesthetic concern, same with the outdoor timber decking. In winter, it gains heat during daytime and releases it in cold night, while in summer, it contacts with the ground to prevent overheating. Carpet is used in bedrooms for comfortable living, and tiles are used in bathroom for hygiene reason.

Ventilation & Shading Strategy
Summer Scenario
In Melbourne, it is critical to keep interior warm and also to apply adjustable shading for occasional weather. To achieve this, we place a maximum number of north-facing glazing to invite solar heat gain, and trapped this heat by using optimal amount of thermal mass (i.e. polished concrete floor in living/ dining space; rammed earth internal wall behind the TV). A minimal number of south-facing glazing ensures less heat loss. However, it is also adequate for cool south-east wind breezes cross the house.
open up adjustable awning if needed good cross ventilation
Pergola & adjustable awning are attached to the decking space, which allows seasonal shading.
Melbourne Latitude = 37.97°
Our client enjoy reading in the living space and bedroom 1 at the west end, so we have a moderate number of west-facing windows with external adjustable louvre shading, which improves lighting condition during daytime but can be easily shaded during sunset.
Equinox = 90° — latitude Summer solstice = Equinox + 23.5°
75.53°
As shown in the perspective above, interior space won’t be overheated during hot summer days because of the pergola design, which provides seasonal shading with climber plants growing on it during summer. If necessary, client can open up the awning for better shading. At the same time, with ample use of windows, the client can still enjoy enough natural light in summer.
Winter Scenario
28.53° Melbourne Latitude = 37.97° Equinox = 90° — latitude Winter solstice = Equinox — 23.5°
As the above perspective shows, winter sun can easily heat up the interior thermal mass of rammed earth wall, brick veneer and polished concrete floor, which subsequently reduce the need for active heating.

02 Passive Design
Solar Power System
Solatube This solatube module combines roof ventilation system, PV panels and skylight. The Pv panels generate electricity to run the exhaust fan. Light emits into the house by reflection inside the tube. It an efficient multi-functional system which will be installed in the bathrooms to replace conventional exhaust fan.
The Tesla Powerwall is applied here as a battery to store over-production of electricity from solar panels. The Tesla Powerwall actually incorporates an invertor inside so that it can be directly connected to the solar panels. It can help to send excessive power to the grid and get paid. Another feature is that client can have smart control of the system on their phones. The diagram on the left hand side indicates how the different components of photovoltaic system come together to work.

Hot Water System
http://www.rinnai.com.au/hot-water/hot-water-storage-systems/electric-heat-pump/ split-heat-pump/
Compared to conventional electricity or solar hot water system, a split heat pump system will be installed, with a outdoor pump and indoor storage tank. On the one hand, the system uses less electricity (which is generated by the solar panels in-situ) compared to electric hot water system. On the other hand, it can continuously generate hot water even in cold winter night, whereas solar hot water system can only do that during sunny daytime. It is also practical that it does not need any roof space for installation and can be installed with two seperate units. In this case, the storage tank can be placed indoor near all utilities. It can not only performs as a potential thermal mass, but the reduction of distance also means using less energy to reheat the water, and ensures quick supply of hot water.
NOTE: With the help of water usage calculator, the annual water consumption of the client family has been evaluated for a better design choice.

Benefits of Using Greywater
Composing Hub
Some utilities in the house does not need to use fresh water, and in this case, greywater from bathroom basins, tubs and other places can be treated and reused for gardening or flushing toilets to: - reduce fresh water consumption and be more sustainable - take advantage of nutrient water to fertilise garden - save money
This is a compositing hub at the corner of the garden (refer to detailed explanation on the right hand side)

COMPOSTING TOILET This is just an attempt of using composting toilet, so this system does not completely replace conventional toilets indoor. Despite this, clients are able to experience generating natural fertiliser for gardening. At the same time, it reduces fresh water consumption and billing, which is both good for the local community and the family.
With adequate moisture and air, worms inside this bin can efficiently decompose waste such as kitchen scraps, fallen leaves and weeds in garden and so on. By using this compost, client can improve garden soil fertility, reduce green gas emission and landfill of local community.
This composting hut is placed in the upper left corner of the backyard. It consists of two parts: a compositing toilet and a worm farm bin.

06 Water Recycling & Drainage
Heat pump
Heating Strategy The heating performance of the house mainly relied on passive design, which uses solar heat as the primary heating source (referred to Chapter 03). However, a moderated number of heating facilities are still installed to meet clients’ demand under some circumstances. In this case, it is decided to apply an electric heat pump system with a radiant hydronic system, which uses self-generated solar electricity and recycled rainwater collected on site. The advantages of combining these two system mainly are:
As shown in the diagram on the left hand side, the heat pump system drives the hot external air into the container via a fan, which transfers its energy to the refrigerant liquid and turn it into gas. Then the gas would be compressed via vale surrounding the tank where it transfers the embedded energy to heat up the water so that the hot water can carry the heat around the house via radiant hydronic pipes and panels. It should be noticed that, the heating system is designed as an independent system without connection to the hot water system. It is because the required temperature of hot water generated by two systems can vary, and we want to avoid unnecessary heating. Also, although this system uses more water source compared to other facilities, the independent installation ensures it always reuses a certain amount water inside the system(i.e. rainwater collected on site) so that it largely reduces water consumption and won’t interrupt domestic water use.
- efficient heating performance & relatively quick response - flexible for applying zoning strategy & avoid unnecessary heating - use electricity generated on site rather than gas, so less carbon footprint - lower operating fee (although the capital fee could be relatively high, it compensates this in a long term use) - less healthy issues compared to AC - no noise compared ducted system There are more resilient advantages which will be discussed in Chapter 09
One heat pump is efficient enough to serve the whole system.

Hydronic Heating System

- consistent profile style as a design feature - in slab hydronic pipes work well with concrete slab
https://www.huntheat.com.au/products
Compared to other facilities, the most outstanding advantage of hydronic heating system is that it is more comfortable without dust, noise or air circulation, and it won’t dry the space, which is essential for the client family with little children. Although it has relatively high capital fee, the operating fee will be extremely low because it is totally relied on renewable resources. Also, when it is connected to heat pump to form a hybrid system, it is really efficient and has extremely low carbon footprint.
Zoning Strategy Most of the time, the family love to gather in the living room to play with kids, so that they decide to spend most of the budget on installing the in slab hydronic heating system. Once opening the west-facing windows, they can easily warm up the whole living space via a heat circulation. In terms of the sleeping area and bathrooms, we only use small hydronic panels where necessary, which are efficient enough to heat up the space and thus save capital fee.

07 HEATING
Evaporative Cooling System
Fan
Cooling Strategy First of all, Melbourne has a temperate oceanic climate, which usually makes it to have relatively cool summer. Thus, the passive cooling design with the assisstance of fan is adequate for most of the days annually (referred to Chapter 03). However, there are occational days of extreme heat and dryness when cooling system is needed. Considerring the client couple working in offices equipped with air conditioners all day long, it is decided that a central evaporative cooler would be used in their home. Only under necessary circumstances, refrigerant air conditioners will be turned on for bedroom cooling. It should be noticed that all the facilities are driven by electricity generated on site, and water souce from rainwater collected on site. Therefore, it is energy efficient and environmentally sustainable. Also, all these active cooling facilities work closely with the passive design. And a zoning strategy is reflected by the compostion of different facilities, which is applied for unnecessary energy loss of cooling.
Compared to other faciliteis, the evaporative cooling system has the following advantage: - cheap capitial & operation fee - runing by electricity generated on site & produce small carbon footprint - really comfortable cooling & adding indoor humidity without producing noise or dust - use rainwater collected on site, so even though it comsumes a lot water, it is still sustainable.
Fan actually does not cool the space, but forces air ventilation to let it form a cross flow in the space. It is really cheap but effective for base cooling demands.
In hot summer days, the client family mainly gather in the living room, and they open windows and doors and turn on the evaporative cooler. With the assisstance of fan, a passive ventilation is formed, and will efficiently spread the cool air throuout the space, and cool down the house.

This reverse cycle air conditioner consists of two split unit, one outdoor unit drives external hot air into the system and uses refrigerant to cool it down and convect the cooler air into the interior space via the indoor unit. It is quick responsive and has efficient COP>3.5, and it is relied on electricity generated on site. Thus, the cooling system is still a reliable cooling facility. In spite of this, we suggest client to rely less on this system unless it is under extreme hot weather.

08 Cooling
Drought
Assessment In terms of water supply infrastructure, this house includes two water tanks, one of which is underground. If drought happens in a short term, the underground water tank would be used as a back-up water resource becuse it won’t . However, if drought continues in a long period, the water supply design cannot satisfy clients’ needs. One thing good about the design is the attempt of building a composing toilet, which won’t use any water to flush it. So it would largely reduce the water demand during a drought period.
Possible Solution & Advice Initially, we would advice clients to have a more sustainable lifestyle and reduce the demands of water, such as taking a 5min shower; using composing toilet and so on. Secondly, the irrigation strategy can be changed to drip irrigation. Thirdly, the client can consider to have access to underground water via a well under extreme circumstances.
Power Outage
Assessment This house has a outstanding performance in energy use. It relies mainly on renewable solar electricity generated on site, and it will be later stored in Tesla battery for contiuous power supply. The roof is almost covered by PV panels, which maximises the generation of electricity. It doesn’t use gas at all, rather, it replaces gas with electricity. Therefore, it is completely self-surfficient in terms of energy use.v
Possible Solution & Advice We would educate clients how to be self-surfficient in terms of energy generation and consumption so that they would be less impacted by the electricity outage of the main grid. It suggests to have multiple Tesla batteries to store more electricity when it is available. However, we suggest to have a wood fire generator connecting to the heat pump and hot water system just in case of the shortage of solar electricity. The gas outage wil not impact the house at all because it doesn’t relied on gas. However, client can have a wood fire stove as backup.
Heat Wave
Assessment This house has a good passive cooling performance by having relective foil insulation, good cross ventilation and roof ventilation, and it is also equipped with adequate cooling facilities. Thus, heat wave will have less imapct on the interior space. The exterior space can be influenced more, for example, the vegetable garden, the roof garden can be really dry with direct exposure to heat wave, and the decking space can also be hot.
Possible Solution & Advice First of all, the exterior decking space will be covered by adjustable awnings and pagola, so it reduces the radiant heat into the window. It also create a volumn of cooler air, which can be forced into the house by a fan to cool down the interior space. The vegetable garden and roof garden can be coverred by reflective membrane to protect crops from water loss and heat damage. A seasonal garden management can also be applied, for example, the family can plant more heat-tolerant crops during spring and summer.
