Site Summary The proposed single dwelling development is located within the Monash City Council Subdivision - SD27375 - Lot No. 194. It is designed as per the planning provisions stipulated in the Monash City Council Guidelines. The plot 194 is rectangular shaped, with its length of 35 meters facing north/south and 15 meters width facing/west.

(Fig.1 Area of the block is 525 square meters.) The house is designed to be a two storey brick veneered timber framed house with tile roofs. Front setback is 7 meters for easement. Double garaged is designed 5.5 * 6 internally and a driveway connected to its gate which is on the left hand side looking from the street. Service connections will be placed on the right side of the block.

Passive Design Features Passive design is a design method that takes from natural climate resources like sunlight and wind to generate heating or cooling for the house. Instead of designing against the weather conditions, engineers can take advantage of the climate to maintain a house’s comfortabilities and reduce electricity and energy use at the same time.

● ORIENTATION The front face of the house is to the West, allowing its long side(35m) facing north. This is a natural advantage for the house to absorb more heat from winter sunlight and produce consistent warmth for the house. While the cold breezes come from the South and East direction less windows should be located in the corresponding faces. Placing more windows on the North side of the house brings more natural lighting and heating.

● INTERIOR LAYOUT Referring to the house orientation. More passive heat will be generated on the North side of the house, so putting most of the formal area to the north is the prior consideration for maximizing the use of passive design. Living room and office is located on the North side of the ground floor and they will be most frequently used. However, the kitchen is to the south of Living room which might take less passive solar in winter. But the kitchen, dining and living area is connected with no objects blocking between them. This maximizes the air ventilation and improves indoor air quality. On the first floor. A bedroom, a decent sized bathroom and the plumpus are located on the North side of the level to enjoy the benefits of passive design while two other bedrooms stay in the cooler side of the house.

● SHADING A large area of exposure to the North also means a large heat traction in summer. A 500mm roof overhang is designed for the house. The extra bit of the overhang can provide shade to the inside of the house, preventing direct sunlight. However, this is only appropriate when it is at noon, when the sun is at the greatest angle which in our case is 79 degrees for Melbourne. It is a very effective way of preventing overheating from the sun. During other hours, direct sunlight may come from sideways, and this can be solved by using external shading objects/devices such as seasonal plants and trees. An artificial shading device is always easy to install thanks to a great side setback distance of the house.

● THERMAL MASS Thermal mass stores heat from sunlight and releases them in a delayed manner. Which means in summer time thermal mass can be used to slow down the temperature rising from inside of the house during daytime, and releases heat into cooler breeze at night. In winter thermal mass can be used to store heat from the day and release into the house during cold night time. Denser thermal mass on the South wall is more appropriate because the South side of the house does not absorb daylight as much as it is on the North side.

● AIR VENTILATION I have maximized air ventilation by aligning the windows and doors where possible. Ensuring windows are installed in the wet area such as kitchen, bathroom and laundry. Most of the windows are placed on the North and South side throughout the house.

● WHAT MORE IS NEEDED Dining area is being placed on the South side of the house which means less natural light and passive solar reaches the area. Putting a single garage may result in more space efficiency but instead a double garage is designed leaving less side setback at where the garage is.
