Rammer Earth Wall (Thermal Mass): The rammer earth walls are used in the north side of kitchen/living area, acting as thermal mass to keep the balance of temperature in this area. Straw bales: The cement finish is not only used for aesthetics, but also provide significant thermal mass. Gardens: The grey water garden and rainwater garden on the bottom have significant water capacity. Water is good thermal mass and the frequent south wind can carry the passive effect.
4. Passive strategies- Shading
Winter sun path
Deciduous Trees: The deciduous trees are used to block sun in summer and allowing heat gain in winter, which also could create microclimate around the house. Pergola with Grape Vine can provide shading and fruit in summer, but will not block the sun in winter as all the leaves will fall. Adjustable awnings are used on the northern windows to block the sun in summer but allow winter sun to come through, which is more flexible.
Figure 2. Pergola on decking 2. Passive strategies- Roof type
Combining a skillion roof with a lean-to roof is applied to the roof system, providing a space for clerestory window and then contributing to ventilation. The angle of the roof is designed to block summer high angle sun while let the low angle winter sun to come through. Eave also helps with shading.

The big panes of windows in this house can provide natural sunlight during the day time. However, electrical lighting is required at night. LED lights are used in this house to set up an environmentally friendly house. LED lights use less energy than traditional lights (approximately 75%) and they release less heat than incandescent lights, which could reduce the risk of combustion. Moreover, LED lights are made of epoxy lenses, so they are more durable.
4. Photovoltaic system: 2
As the clients are very eco-conscious and want to set up an environmentally friendly family, photovoltaic system (PVS) is installed on the roof to generate electricity. The Tesla Powerwall is used to store energy to meet the requirement when demand exceeds output. The inverters turn energy from DC to AC mains power. In terms of PV panels, poly crystalline is used on the PV system as they could “not lose efficiency with higher temperature”.

Active (pumped) solar water system is used on this house to provide hot water, which used electricity produced by PV system to power the pump and booster (Figure2.). When the electricity produced by PV is used to power the pump and insulation layers are also applied to the pipes and storage tank, the active system can reduce energy loss as much as a passive system without adding roof load. Our clients agree on a higher cost of active solar water system. They want a larger storage tank that could be enough for five people to get shower and they do not want a storage tank to cause a visual impact.

1. Sewer System
3. Grey water system
Water from toilets and kitchen sinks produce black water and they are connected to main sewer system to discharge the black water through sewer water pipes. All the sewage is discharged in the main sewer pit (the lowest point in the site). The black water contains hazardous chemicals and flush water from flush toilets, which will cost too much to reuse it. Therefore, in this case black water is discharged directly to sewer system.
Greywater is water wasted from “non-toilet plumbing fixtures” such as showers, washing machine and it is collected in a grey water tank. In this case, grey water is used for toilet flushing and garden irrigating. Grey water is directly used for toilet flushing. However, coarse filtration (“fine filtration and biological treatment” by using a sand band and reed bed) is needed before reuse or disposal to sewer to remove large particles. Moreover, all the grey water must be discharged immediately after 24 hours to the main sewer pipe. The size of grey water tank is 1500 L.
Vegetable Plot
All the sewer pipes follow the convention of “no right angles” as right-angle sewer pipes may cause congestion. Moreover, these pipes are downward sloping to use gravity to create a smooth flow.
2. Sewer Vent
Dietes Grandiflora
Sewer vent is installed in the end of sewer pipes to ensure the ventilation of sewer system. It is used to make sure there is an air movement in the system to “decrease gaseous build ups”. Moreover, it could also prevent solid waste from sticking into the surface of sewer pipes and cause congestion, and then make the whole system fail.

2. Heating strategy-Passive heating Passive heating strategies (orientation, window sizw and direction, thermal mass etc.) are also applied to this project to ensure the house keep comfortable temperature with lowest energy cost in winter. (Details with passive heating are demonstrated on page2- passive thermal) In the extreme weather, when passive cooling is not enough, active hydronic in-slab heating systems work as an alternative way to keep the house warm in winter.

In this house, both heating hot water system and domestic hot water system use heat generated from the evacuated tube solar collectors(Details in Page 5. Water and gas supply). The flited rainwater is pumped into evacuated tube solar collectors on the roof. The evacuated tube solar collectors of active solar hot water system generate solar energy to heat the water in the ground hot water tank. The outflow from hot water tank is divided into two flows, one for heating and the other for domestic use. Thermostats are installed in the circulation of hot water system to sense and maintain the water in a desired set-point.

3. Heating strategy- Hydronic in-slab system and Hydronic panels
As the clients are eco-conscious, hydronic in-slab heating system and hydronic panels connected to solar hot water system are used to heat this house in winter. The reasons why choosing hydronic system are it is zoning possible (only heat the key areas and save energy) and can used the flited rainwater (save water bills). In the kitchen, dining room and living room, hydronic in-slab system is applied under the bamboo floor to provide heat for these high-use spaces. In three bedrooms covered by carpet and bathrooms covered by tiles, hydronic panels are used to provide heat as it is zoning possible and will not be disturbed by floor covering. The hydronic panels on three bedrooms are located under the window sills to “mix air temperature inside the room and avoid condensation on glazing”. The laundry which is not used a lot and services area in kitchen (not suitable to run coil) do not use any heating strategy.

2. Cooling strategy-Passive cooling:
1. Cooling Energy Load Based on the cooling energy report of first rate, the key rooms that need more cooling strategies are kitchen/dining, living room and bedrooms. These rooms are also the high-use rooms in this house.
Passive cooling strategies (cross ventilation, shading, thermal mass etc.) are also applied to this project to ensure the house comfortable with lowest energy cost. (Details with passive cooling are demonstrated on page2passive thermal) In the extreme weather, when passive cooling is not enough, active cooling systems (Ceiling fans and evaporative cooler) work as alternative ways to keep the house cool in summer.
Summer (Standard-Counterclockwise) Draw the cold air down
Winter&Summer (Reverse-Clockwise) Winter: Draw the warm air down. Summer: Draw the cold air up and circulate it
Ceiling fan rotation system (Figure2.)
4. Cooling strategy-Ceiling fan:
When the humidity levels of air are above 50%, the evaporative system is not suitable. The clients agree to use ceiling fan in key rooms as an alternative cooling strategy in humid weather. The ceiling fans do not create actual cooling, but they can accelerate the movement of air and create cooling effect by using latent heat of evaporation. Moreover, the ceiling fans with reverse mode can not only blow the air down but also “draw the cool air up and create and drive them circulate� at the room to make people really feel it.( Reverse mode is generally used in winter to draw the warm air down.)

3. Cooling strategy-Evaporative system:
Evaporative cooling system is only applied to the key rooms (living room, kitchen, dining room and bedrooms) to distribute cool air in summer for the clients in high-use space and save energy. Evaporative system is a ducted cooling system located on the roof, which reduces the room temperature by using latent heat of water evaporation process) with lower running cost (Figure 1.). The evaporative system is connected to main water system to ensure the moisture provided by this system is clean and no bacteria. The water used by this system will be discharged to the eaves gutter and then discharged to the down pipe. The clients are eco-conscious, so the evaporative cooling system with low energy cost is suitable for them. Moreover, this system refreshes the air in the interior space every minute, providing a healthy and comfortable living environment that is suitable for the clients, especially for the three children. However, using this system can increase the humidity of air, which need to be expelled by opening windows or doors. The clients agree to use this system as an alternative cooling system as this system works best only when humidity levels are below 50%.

2.Weaknesses or vulnerabilities:
The north side of Henrys’ site is the national park which is full of vegetations, which means it will catch fire easily. Moreover, the surrounding deciduous trees are also at a risk of bush fire. The roof frame of this house is made of timber, which also catch fire easily. Moreover, all the windows on this house are lack of bush fire proof.

Roof plan 1:200@A3 3. Bush fire solutions:
The Flame trees (Brachychiton aecerifolius) with fire resistance are planted in the surrounding area to protect the house from bush fire. A continuous rainwater garden is located on the surrounding area and connected with the vegetable plot on the north side to reduce the fire risk from the national park. (Water and soil in gardens can prevent the house from fire). The wall material of the house is 450mm finish straw bales, which are also fire resistant as they are compressed tightly and the clay finishes. The northside of the roof are designed to be an extensive green roof, which can not only shade the roof but also works as a fire-resistant layer. All the windows are equipped with fire shutters so the clients could shut down the fire shutters to prevent the interior space from catching fire.
