CLERESTORY ROOF

VEGETATIONS

Trees used as a way to moderate the effects of penetrating winter winds and also capture the cooling brought by summer breezes.

Evergreen trees are proposed to put at the north, east and south sides. In winter, winter winds can be prevented, in summer, it can provide shade from summer rays.

Deciduous trees blossom in spring and shed leaves during autumn, placing them at the west side so it can provide shade for summer and allow sunlight to go into the house in winter.

Awning windows are added due to the roof structure, they are facing north. This allows more sunlight going into the house during day time, especially the southern part of the house which is originally restricted to receive sunlight. Besides, ventilation is allowed. The window with a motorised blind that allow glare and solar heat to control manually.

With the use of motor then it can be adjusted easily as the clients are elderly and it is hard for them to climb up to adjust the blind.

CLIENT INTERESTS The Patels always babysit their fourteen grandchildren and this will be the main active house activity. Besides, they appreciate the concept of an energy efficient building and would like to apply this on their house. Regarding this, they share a wish of zoning the house off when their grandchildren is not around so as to save energy and eventually lower their energy bills.

Moving to a new outer suburb, the neighbourhood will be comparatively more quiet. It will be a pleasant living environment for the Patels. As an elderly, maintaining general well-being is essential, their health can easily get affected by the climate. Regarding this, a very efficient heating and cooling is required in order to maintain general well-being from not getting sick.

As the main users of the house are not just Mr. Patel and Mrs. Patel but also the fourteen grandchildren, the activity of children is far more The structure is working together diverse and active when compares with elderly. Thus, more open space with climbing plants on top, this is in outdoor is needed to allow different activities.

IMPACTS FROM/ON NEIGHBOURHOOD The adjacent property is double storey so it is able to block some sunlight from the west so the bedroom facing west will not be too hot.

As the house is single storey so it will not be able to block the sunlight or overshadow the adjacent properties.

SITTING AND ORIENTATION:

Living room facing north which allows the maximum of sunlight going through in both winter and summer since it will be the place where the client spends the most time in.

Client’s room facing southeast so no direct radiation going through the room, it makes a more pleasant environment with no differentiated temperature between day and night time.

LIVING ROOM:

-with living room facing north adding windows facing south then cross ventilation is allowed

NATURAL VENTILATION STRATEGIES Melbourne’s wind mostly blows from the north and south, an efficient natural ventilation within the house can simply achieved by having doors and non-fixed windows at both sides.

Air movement - air cools the house down by remaining the cool air from the outside the house and carrying heat away from the house

5. Casement windows used in all bedroom -it allows less ventilation if little window space is opened, it allows less wind going in then it will be better in maintaining the room temperature 6. Bedroom 1 window with roller shutter -as the window is facing north so sunlight can reach the room over the daytime so it is necessary to add roller shutter so that it can block the direct rediation -if not adding roller shutter, the bedroom will be too hot for people to sleep during the night as the heat is not able to release very quickly after sunset 7. Amenities rooms’ windows with louver -as the windows are facing west where will be the hottest sunlight shining on so louver is added on each window so that it can block the sunlight and cool down the temperature of the rooms

This hotwater system is fully depending on the solar access, solar panel is placed on the roof at 30 degree facing north to receive as much as sunlight. By transferring water(cold) into solar panel via main water pipe from street , with sunlight heating up the water then it transfers the hot water to the hot water storage. When the client open the water tap and wish to use hot water then hot water will transfer to it via booster. Booster is required in this system as it helps to heat up the water when sunlight is not hot enough or on cloudy days. But still hot water storage may transfer water which is cooled down back to the solar panel to heat up again.

Stormwater goes to rainwater tank for recycle via the downpipes, it will be treated and used for toilet flushing. If the tank over flows, the stormwater goes to LPD (as shown in page 5).

GREYWATER SYSTEM Greywater system will be used as the way to recycle used water and the recycled water will be used in the house again so as to achieve energy efficiency and save energy.

Greywater takes the water resource from used water within the house. The sources include shower, washing machines, sinks in both kitchen and bathroom. After the water is treated then it will be resued for toilet’s flushing and watering the garden. It locates in the backyard of the house so the client will not get close the greywater system.

By introducing greywater system, it can lower the water bills. However, there is something to do with the garden, as watering the garden and tree are using greywater then the plants chosen to plant in the garden should be drought resistant plants and can be watered by greywater.

Heat source: hot water storage located at both sides of the house

Hydronic panel heating is comparatively very expensive among other choices of heating system. By considering the condition of the client as an elderly couple with a mission of babysitting their 14 grandchildren accordingly, it is necessary to use this heating system. It is a very comfortable heating system featuring radiant heat with no dust which causes no harm to the client and their grandchildren’s health. In each bedroom, a hydronic panel will be put in nearby the bed, client can choose to switch it on if they need to, this system at the same time fulfills client’s expectations to zone off the house when the kids are not around so they can just switch on client room’s panel for heating without consuming the energy used for entire house. Also, it uses natural resource to generate heat so it saves energy and hence saves money for bills.

With such pattern, even though heat loss occurs during the process of in-slab hot water transfer, with inputting hot water and outputting cold water, it moderates the temperture and make sure the temperature will not be cold when there is heat loss in the process.

WALL HUNG SPLIT SYSTEM Diagram showing how the cooling system works:

Indoor unit

Wall hung split system is used in the living room as a cooling system. It operates with electricity so it is comparatively less cost-efficient. Also, the electricity bill will be more expensive if the client switches it on frequently.

It is installed in the house since the client is an elderly couple. Their health will be affected by the weather easily. Just in case if the heating system is out of order or Melbourne is experiencing heat wave then client can use the split system to generate hot and cold air for their needs.

Connecting pipes

Condenser

Split system consists of three element: Indoor unit, outdoor unit and connecting pipes. It absorbs hot air and blow cold air out. It is ver y efficient but environmentally unfriendly. The absorbed hot air will be transferred to condenser via pipes and then blow out.

It is just for the living room since it will be the space that a family spend the most time at during daylight. As Melbourne’s temperature Indoor Outdoor cools down during the night so it does not Input unit - cold air out, hot air in necessary to make split system in ever y bedroom Connecting pipes - transfer hot and cold air so as to save cost and minimise electricity bill.

Condenser - blow hot air out

CEILING FAN

PASSIVE DESIGN STRATEGIES

As mentioned on page 3, ceiling fan will be used in the living room and the bedrooms. It is to help with natural ventilation to make cool air to stay in the house and flow in the rooms. This will make help cooling down the rooms in summer. And sometimes, if client would like to have a afternoon nap, they can switch on the fan so it makes the rooms cooler. During winter, switch on the ceiling fan to rotate in the opposite direction as summer will help to store the warm air in the house.

The natural ventilation is working well in this house (see page 2), with the use of different windows, it allows air to flow in and out. Also, the roof design, by having awning window on clerestor y roof structure. It allows stack ventilation that makes air flow more efficiently.

Natural ventilation and ceiling fan working together, as an outdoor garden is created plus there are trees surrounding the house. It helps changing the wind direction to aviod strong wind entering the house.

9. HOME USER MANUAL Welcome to Galah House! This manual is going to guide users to get familiar with this house!

1. How to pull up a roller shutter As bedroom 1 is facing north, sunlight enters to the room during the daytime which will be very unpleasant so a roller shutter is added to the window for additional shading. To block the sunlight, user can simply release the rope so the roller shuttle will go down to cover the window. If user wants to have more sunlight enterting the room, user can pull the rope up so the roller shuttle will go up.

2. How to switch off all the lights in the living room at once To bring convenience to the user, there are two multiple light switches at the entrance and by the end of the corridor outside bedroom 2. It connects to all the lightings in living room plus the ceiling fan. This is for the users if they are in the bedroom but forgetting to switch off all the lightings. Instead of keeping them to run around for light switches. There are one single switches to operate all the lightings and ceiling fan in the living room.

6. How to allow natural ventilation By opening the window and sliding door highlighted with As Melbourne’s wind mainly blow from the north and south so the wind will enter via the window facing south then going through the house.
