NEEDS

S

E

The Patels are an elderly couple who are planning to move to a vacant block at Hoppers Crossing. They have fourteen grandchildren whom they are always babysitting.

Being elderly, the couple often gets sick and therefore needs very good heating and cooling. They like the idea of building an energy efficient house so that their energy bills will be lower in the future. They also like the idea of being able to zone the house off when the grandchildren are not around.

The Patels have also been researching Environmental Design in their down time and are interested in using their house to show off many of these principles. They also want to utilise local materials with a low embodied energy. Seeing greenery from windows is also something they desire. One of the grandchildren also has asthma so the heating and cooling systems need to cater for this. The couple also wish to produce their own fruit and vegetables on site to reduce their reliance on transported goods.

Finally the couple wish to save and reuse water where ever possible, but not to an extent which may cause them health issues due to their weak immune systems.

EAVES SECTION + CALCULATION

Two thermal mass walls will be built in the main living area to provide thermal mass within the building. One wall will be shared with the master bedroom to provide heat in winter into the bedroom. The flooring will also be selected to increase the thermal mass of the house. The thermal mass will be utilised as a part of both the passive heating and cooling strategies.

VENTILATION/ PASSIVE COOLING

Cross ventilation has been utilised to passively cool the house.

Louvered windows have been positioned in the living area in front of a water body to allow for cross ventilation and cooling breezes.

All living and sleeping rooms have been designed with a minimum of 2 windows for effective ventilation. Stack ventilation will also be achieved through the roof type with clerestory windows.

ROOF MATERIAL

The roof chosen will be a divided into two materials based on the split pitch of the roof. A green roof with native succulent varieties will be grown on the Northern half of the roof and colourbond steel sheeting will be used on the Southern portion.

The green roof was selected for its low embodied energy, its addition of greenery to the site as well as its environmental and sustainable building benefits. The green roof be an extensive green roof with a 200mm substraight reducing the need for large structural beams, as succulents only have a shallow root system. Succulents are also drought hardy and require little to no watering making them suitable for the sites climate. The roof will also attract native wildlife adding to the buildings ecology and it will also contribute to the buildings thermal performance. Finally the choice of roof will contribute to the storm water management of the site.

The use of colourbond sheeting on the second half of the roof will allow for rainwater harvesting for use in the house. The sheeting will be recycled and tin (silver) in colour to reflect the suns rays. The choice to source recycled sheeting is to reduce the embodied energy of the steel as it requires a great amount of energy to be produced.

A concrete slab-on-ground will be used as the flooring choice with the use of a geopolymer binder system instead of cement and recycled aggregates. The slab will be used to provide thermal mass the for internal space. The slab will be fully insulated around the vertical perimeter to the full depth of the slab as well as underneath using rigid polystyrene insulation.

The insulation is to have a minimum R-value of 1 and be water resistant. (http://www.globalgreentag.com/products/recycled-32-mpa-con crete/) (https://www.wagner.com.au/main/what-we-do/earth-friendly-concrete/efc-home) Under floor heating will also be installed in the form of a horizontal loop water to water ground source heat pump (GSHP) sourced from GEOExchange Australia (https://www.geoexchange.com.au/products/#pro-title2).

The concrete slab will be the final flooring finish to allow maximum thermal mass capabilities.

WALL MATERIAL

Local wheat straw bales will be used for the external wall construction (450mm wide) with 50mm earthern render skin to provide thermal mass. The bales will sit inside a timber frame made from recycled timber which has been FSC certified. The bales were selected for their high insulative properties with an R-value exceeding 10, as well as their low embodied energy and negative carbon footprint.

Two rammed earth walls will also be built in the main living area to provide thermal mass within the building. One wall will be shared with the master bedroom to provide heat in winter into the bedroom. The other internal walls will be timber stud walls filled with insulation to maximise the efficiency of the zoning.

A good rule of thumb for Victoria is; 30-60% Northern 10-30% Eastern + Western 5-15% Southern

Overall, these insulation products were chosen to maximise the retention of heat within the building envelope, whilst still being conscious of the clients desire for materials with low embodied energy - hence the move towards recycled products.

The values for this house are slightly different to the rule of thumb however this was due to the location of key services such as the Kitchen which determined and restricted where large sliding doors to the outdoor area could be located. Overall other Passive Solar Design Strategies were implemented to supplement the near perfect window orientation.

HOT WATER SYSTEM

WATER SUPPLY FROM RAIN ON ROOF

An instant hot water system run off electricity generated from solar power will be used in the house. (https://www.stiebel.com.au/water-heaters) The reason for this is there is only 2 people using hot water on a daily basis, so a large tank is not needed. An instant system also allows for an infinite supply of hot water when family comes to visit using more hot water. This system was also chosen as no excess energy is wasted maintaining a temperature of over 60 degrees Celsius all day and night which is required for a large hot water storage tank.

This hot water system will be an open system compared to the hydronic heating system, with waste water being flushed to the grey water system and sewer.

No solar hot water was used as it was more efficient for the client to have more solar (PV) panels on the roof to use as a clean source of energy for heating the water, rather than installing a system on the roof which would also require a tank.

Rainwater will be collected from the southern side of the roof into a 10,000L rainwater tank (selection justification on page 06). The rainwater system will have a first flush mechanism to remove any contaminants from the first few millimeters of rainwater coming off the roof. The roof will also have gutter guards installed to prevent leafs and other debris from clogging the gutters.

A small pressure pump will be installed and connected to the rainwater tank to move the water around the site. This will be a freestanding pump to save on cost. The rainwater tank will also have a mains water backup.

This decision was made as the couple being elderly and with low immune systems were hesitant to drink the rainwater and did not want to install excessive treatment systems. Therefore it was decided that it would be best suited to water their garden which they hope to produce their own food from to be self sufficient.

Ability for neighbors to link in

GAS

It was decided that gas would not be installed and connected to the site as the couple would like to be as environmentally friendly and sustainable as possible. As gas is a finite resource which is not yet renewable, the couple decided to opt for electric appliances and forms of heating, for which the could produce their own clean, green power for via their PV array.

They would also like to showcase environmental design principles which they believe also includes the move away from gas.

A 10,000L rainwater tank will be installed along the Southern wall of the house to collect rainwater from the tin sheeted side of the roof. As only one half of the roof will be collecting water it will be a dry system. The size was determined based on an average water usage of 476L/ day with a roof collection area of 71m^2.

The tank will be white to reduce any excess radiant heat gain in summer. (http://tankulator.ata.org.au/interactive.php) (https://www.bunnings.com.au/clark-tanks-10000l-round-poly-wa ter-tank-white_p4818820)

The rainwater tank will be used as a back up to the grey water system, to wash clothes, supply water to the showers as well as to water the garden.

S

The choice to go for a big tank despite not using it in the house is because they want to be self sufficient in their garden to produce their own fruits and veg to be sustainable. As a result the rainwater is also connected to a irrigation system to water their vegetable gardens at the rear of the site as well as other parts of the garden.

GARDENS/ LANDSCAPING

GREY WATER

To maintain an environmentally and water saving garden the following items have been included:

Grey water will be collected from the bathrooms and laundry and will be used to flush the toilets. The grey water system will be backed up by the rainwater tank.

S

- Drip irrigation garden beds using rain water - Compost bins to recycle food waste on site - Chickens (for food waste etc, natural manure, food) - Bees for honey production and pollination of the fruit trees/ vegetables - Crushed brick/ concrete paths as they permeable and use recycled materials - Native deciduous red ceder trees - Low shrubs + lawn/ ground cover instead of pavement to reduce glare - grey water tolerable plants such as Yuccas and gardenias - Native plants and trees which are suitable for the area and require minimal watering - Mulching of garden beds to reduce water loss through evaporation

Grey water friendly products such as washing detergents and soaps will be used to minimise chemicals coming back into the house and then out into the waste water. (www.greysmart.com.au) As well as for the environmental benefit, this will enable them to change where the grey water is used in the future, for example on the gardens, with minimal impact on soil salt and pH levels.

The grey water system will be fitted with a pump and timer to remove any grey water which has not been used within 24 hours.

This will be moved into the natural pool to be filtered through the plants and then out into the legal point of discharge.

STROM WATER

RAINWATER OVERFLOW TO NATURAL POOL

The site will have a natural pool as a form of on site storm water detention to hold runoff a little longer to lessen the impact of the downstream flooding. Rainfall from the green roof will be directed into the natural pond as well as other storm water that falls on the site. The pond will feature aquatic plants such as reeds and lilies to discourage algae bloom and to filter the water.

GREY WATER 24 HOUR TIMER OUTPUT TO NATURAL POOL

Excess from the rainwater tank and grey water systems will also be diverted into the natural pond. The pond will then have an overflow connection to the storm water drain to prevent the site from flooding.

INTERGENERATION INTO PASSIVE DESIGN

HEATING SYSTEM

Passive design also plays a large role in the heating of the building with insulation and wall material choices helping to retain heat within the building envelope. The following principles have been implemented to aid in the heating of the building envelope;

The house will be heated via hydronic in-slab heating in the main living areas and by additional hydronic panel heaters with individual thermostats in the bedrooms and bathrooms. The hydronic heaters will be connected to a ground source heat pump and hot water storage tank. This system will be closed and solely for the function of heating. (https://www.geoexchange.com.au/products/#pro-title2) This is in addition to good thermal design and insulation, reducing the overall amount and frequency of heating needed throughout the year.

- Straw bale external walls with very high insulative properties - Concrete flooring which has a high thermal mass to maintain a constant internal temperature during day and nighttime - Deciduous plantings to enable winter light into the building envelope

The ground source heat pump will be used to heat up the water for the heaters and there will also be the option for the neighbors to link into the system if they so chose, to make it more environmentally friendly and cost effective. This was chosen as the site is large, flat and empty so the clients were able to excavate and install the system. It also utilises free energy from the earth, being a more environmentally friendly approach.

- Eaves and shade structures designed at the appropriate angles and lengths to allow in the low warm winter sun - Heavy curtains with tight fitting pelmets to reduce heat loss through windows - Double glazing to reduce heat loss through windows - Location of hot water tanks inside the building envelope to allow any escaping heat to warm the house

The fans used throughout the house for cooling will also have a reverse cycle function so that they can be used to push the warm air down from the ceiling closer to body height.

SELECTION CRITERIA

CLIMATE As Melbourne is predominately a heating climate it was important to install an adequate heating system. Summers generally produce hot dry heats, however recently due to global warming humidity levels have been rising which has been causing issues with evaporative cooling devices.

To ensure constant comfort and warmth throughout winter in-slab heating was preferable as it was directly in contact with the occupants and a comfortable form of heat producing radiant, convective and conductive heat (not dry or dusty).

PASSIVE THERMAL PROPERTIES The heating being in the slab also aids in creating a constant temperature overnight as well as during the day, with the concrete slab’s thermal mass retaining some heat during the day and releasing it during the night.

BUILDING FUNCTION The heating selected allows for freedom in furniture layout and changes as the heat comes from the floor in the main living areas.

For the bedrooms and bathrooms, the panel heaters suit the buildings function as they can be turned on and off and zoned as needed.

SYSTEM PERFORMANCE This heating method provides radiant, convective and conductive heat so it is the most comfortable. It can also be controlled with a thermostat and each panel heater also has its own individual thermostat for zoning. The system is also very quiet making it comfortable to run overnight. The lag in response time for the in-slab heating is not an issue for the owners as they will be turning it on early, around Autumn, and leaving it on constantly throughout winter. The panel heaters however are faster in their response time and will be turned on and off as needed.

CLIENTS BRIEF The type of heating fits in with the clients desires as it does not produce dust which can aggravate health conditions such as asthma. It can also be zoned when the whole house is not in use.

It is also a comfortable form of heating which will warm them up as their feet are in direct contact with the warm slab.

Finally the system has the potential for other neighbors to connect into the heat pump, showcasing great environmental design principles.

COOLING SYSTEM

The cooling of the house will primarily be achieved through the passive solar design, limiting the need of any additional cooling.

However, to ensure comfort throughout the year ceiling fans will be used to provide cool breezes and to circulate air. The ceiling fans will also have dual summer/ winter function to be able to push warm air down in winter as well as push it upwards in summer. They also have variable speed control for greatest efficiency and inbuilt LED lights.

Summer sun

The chosen fans for the house are Mercator 130cm White Europe Ceiling Fan With LED Light available from Bunnings. (https://www.bunnings.com.au/mercator-130cm-white-europe-ce iling-fan-with-led-light_p0043519)

Correctly calculated eaves to allow winter sun

SELECTION CRITERIA

CLIMATE As the climate is mainly a heating climate, with good passive design strategies minimal cooling is required. As a result ceiling fans are an adequate form of cooling.

Internal fans to circulate air

PASSIVE THERMAL PROPERTIES Ceiling fans aid in the buildings passive cooling function by moving and circulating air through the building envelope.

Deciduous vegetation to block summer sun

SYSTEM PERFORMANCE This system is the most cost effective at only 1c/ hour to run, as well as being powered by electricity which can be generated on site via the PV array which would eliminate all energy costs. It is also effective as it moves air over the skin increasing body heat loss by convection and evaporation.

Cross ventilation/ afternoon breezes

PASSIVE AND MECHANICAL COOLING DIAGRAM

CLIENTS BRIEF Utilising ceiling fans aligns with the clients brief of making the house energy efficient and reducing energy bills. The clients have strictly specified good heating in winter as they often get sick however they do not mind the heat so ceiling fans and passive thermal strategies are sufficient forms of cooling for them. This is also showcasing environmental design strategies which they wanted to showcase as they are not relying on refrigerated cooling like most homes do.

INTEGRATION INTO PASSIVE DESIGN

The passive design of the building plays a large role in the buildings cooling. The following passive design principles have been integrated into the building to aid in cooling the house: - Night purging of warm air in the house as well as that store and released through the thermal mass via stack ventilation with louvers used in the roof split as well as louvers at floor level

CASEMENT WINDOWS TO DIRECT BREEZES INTO THE HOUSE

Source: www.yourhome.gov.au/passive-design/passive-cooling

- Water ponds outside louvered windows to bring moisture and cool the air down as it comes into the building (mother natures evaporative cooling) - Planting of deciduous and evergreen tress and vegetation to limit the amount of heat that can enter the building - Funnel planting of trees to direct cooling breezes over the water bodies and into the house - Green roof to act as a thermal barrier and insulation to reduce internal heat gain - Light coloured roofing material to limit radiant heat gain - Fixed timber vertical batten screens and deciduous vines - Large eves to cut out harsh summer sun - Casement windows to allow for ventilation and airflow through the house - Heavy insulation in the walls and ceiling to stop heat transferring into the building envelope - Utilising the ground source heat pump to cool the slab via the hydronic heating system by cooling the water to ground temperature removing heat via convection from the slab
