THE CLIENTS

The house is pulled close to the street to generate space for the backyard and the garden. Being flanked by two storey brick unit houses, this frontal location of the house is also necessary to maximise solar acess while maintainng a cohesive streetscape.

The Patels are a pair of elderly couple who have just purchased a patch of land in Melbourne’s newly developed outer suburb next to Caroline Spring. Having newly retired from positions as teachers of the enviromental science, this wealthy couple are willing to go all out to reduce their carbon footprint yet without having to compromise on the comfort of their home.

The primary living area is facing north to maximise sunlight access throughout the day. A pergola with ADJACENT PROPERTIES deciduous vine is also added to the north facade as a shading device in summer. Bedrooms are orientated towards the south as these rooms, especially the two guest bedrooms, will have minimum occupancy during daytime.

Being retired, the couple occupy the house all day. They like to garden and are very much interested in the idea of building a premaculture garden of their own. The couple also have 14 grandchildren who occasionally visit their house and they would therefore like their place to be children friendly. They have also expressed an interested in using natural, chemical free materials in construction as Ms Patels have a slight ashma condition and would like to stay away from active systems that produces uncomfortable drafts.

GARDENS The house is deisgned to accomodate multiple gardens. A rain garden system is placed at the front of the house not only as an aesthetic addition to the front pouch but it also serves to delay stormwater runoff. The Patels are interested in constructing a permaculture garden of their own. The area designatede for food production is placed close to the kitchen and the covered patio, making it easy to access basic herbs and vegetables. With two dry system rainwater tank installed on either side of the house, the Patels can easily acess water for gardening from the designated outlet.

DESIGN RESPONSE The design purposed is an enviromentally concious house that utilises sustainable materials and runs upon renewable energy. Despite the initial investment, the house operates on a low running cost enabling the couple to age in peace without having to worry much about the rising energy bills in the future.

SITE ANALYSIS CLIMATE The site is classified as Climate Zone 6. This naturally mild climate provide greate opportunities for utilising passive design strategies to achieve comfort.

SHADING STRATEGIES

NATURAL VENTILATION STRATEGIES

PASSIVE SOLAR DESIGN: SOLAR ACCESS AND NATURAL LIGHT A major design challenge of the site is that the client’s solar access is limited by the double storage brick unit of the neibouring houses. As a solution, the house is designed with many skylights especially in the south facing bedrooms to provide comfortable natural lighting and limit the use of electricity in day time. These solar powered operable skylights can also be used as a stack ventilation device.

DOUBLE EAVE ROOF DESIGN

MATERIALS AND CONSTRUCTION

SUSTAINABLE TIMBER SOURCING

PAGE 03

The timber for the window and door frames are sourced from the manufacturer Accoya whom select trees from fast growing certified forest. The wood is modified for durability. Their products are FSC certified.

WALL DESIGN: STRAWBALE This house is purposed to be built with Strawbale. Sourcing the material locally from the professional construction company Huff’m’Puff located in Waga Waga, the compressed and treated strawbale will achieve an insulation value of R4.54. Combined with the draught sealing detailing, the house will have a airtight building envelope that keeps a constant temperature inside which is ideal for the comfort of elderly couple in the variable climate of Melbourne. The natural insulation properties of the material is also without chemical and thus free of health concerns.

All light fitting uses LED. They are the most energy efficient option with a lower running cost than incandescnet halogen lights.

The average lighting usage is 1.79 W/m2 which is less than the maximum of 5W/m2 allowed by the NCC lighting regulation.

Needing to babysit their various grandchildren at different times throughout the year, the energy expenditure of the Patels couple flucuates throughout the year with usage likely to peak at the school holiday seasons.

RENEWABLE POWER GENERATION While connected to electricity, the Patels has a large garden and have multiple pumps for the water system that relies on solar energy. The solution is a 4kW solar system made up of twelve 370 Watt panels. SYSTEM

PAGE 08

CHOOSING ACTIVE SYSTEM: MINIMUM ACTIVE COOLING REQUIRED Caroline Spring is located in Climate Zone 6 which is classified as having a mild temperature. With good passive design in place, it is decided that the house will not be fitted with a cental cooling system.

HEAT WAVE SOLUTION: PORTABLE SPLIT UNIT

TYPE

IMAGE

Considering Patels’ elderly age, the house will be provided with a portable split unit in case of extreme weather conditions.

RINNAI portable Arit Conditioner

While the system is less energy efficient than fixed ones, the reason for selecting a portable unit for cooling is for its mobility. Instead of confining the client in the cool conditioned place of the living area, portable system can also be taken into the bedroom at night if needed during extreme weather scenarios.

PASSIVE COOLING

Although the clients’ fragile health condition requires maximum thermal comfort, Ms Patels has a slight aesthmatic condition which makes her distrust cooling system that produces a drift. Along with the use of passive design strategies, the cooling selected is a system of fan.

The house mainly relies on passive strategies to achieve thermal comfort in summer. 1. STACK VENTILATION

COVID-19 RESPONSE

PAGE 09

OTHER RESPONSES SUGGESTION A. GARDEN AND VEGETATION

COVID - 19 IMPACT ANALYSIS

The Patels like to garden. Having free time on their hands they can expand the area for food garden to the front and back of the house so that they can be self provident and do not have to be so reliant on grocery delivery. They can also manage an irrigation system using excess rainwater as water usage may decrease with the absence of the grandchildren.

TABLE

THE CLIENT’S CHALLENGE Being retired, the occupancy of Patel is not factored to significant change as a result of the Pandemic. Their C energy consumption may even decrease as a result of the absence of their grandchildren. As a response to the Pandemic, the house is proposed to be improved on the lines of providing more comfort as a self-providing healthy shelter for the elderly couple.

They can also look to plant more trees around the peripery of their house. Ground covers such as creeping boobialla and pronged grevilea are fast growing and will add to the microclimate around the house, even providing a natrual air filter that might have possitive benefits upon the couple’s health.

With active system fitted according to the zones and two seperate rain water collection tank for the different areas of the house, the couple can effectively reduce the operating area of the the house by half, saving resources and reducing energy bills.

B. REUSING THE GUEST BEDROOM They can change the guest bedroom to a function area for the comfort of having more space by connecting the room to the master bedroom forming an ensuite. This space can be used as a private living area for the couple acting as a library so that they can read instead of worrying about the pandemic all the time. The room can also be used as a family theatre for the children when time returns to normal.

REDESIGNING THE HOUSE FOR SELF ISOLATION In the light of the Pandemic, a new zoning approach is purposed (as indicated by the pink area in the Plan). A small “ensuite” within the house is created that can be accessed through a seperate entry from outside. This segregated living space can be zoned in the unfortunate event if one of the Patels is contaminated by the virus and need to self-isolate. Through this approach, they can look after each other under the same roof but without increasing the risk of contamination by using the same amenities.

C. GOING OFF GRID With the grandchildren completely off sight, the Patels may actually experience a decrease in their energy consumption. Already having many renewable systems installed, the Patels may even be able to operate their house off-grid. They can look to invest in other technologies such as composite toilets and aim for complete selfsufficiency and prepare for the possibilities of stricter future epidemics which may happen to the human race. D. CONNECTEDNESS The Patels can also be looking to upgrade their internet connection to the 5G network to better Skype with their family. They can also set up a table in their front yard as a method to contactless offer their excess food produce to their neighbours as a friendly act during the depressing time.
