• Inslab Aquacomb Tanks. 38 individual pods (10,000 litres in total) linked together by pipework, whereby fresh air for the HRV will pass through them all over a combined water area of 55m2, acting like a radiator to moderate the fresh air temperature.
• Further to the above, the stored water will be used to all Toilets within the house and to the Laundry, as well as for external irrigation, minimising water usage considerably.
• Heat Recovery Ventilator (HRV) – As the house is being constructed air-tight, there is a need to ventilate the house to remove stale air. To ensure the stable internal air temperature is not effected by bringing in external fresh air, which could be considerable cooler or warmer, a HRV is used. The selected high quality German system being used transfers energy from the incoming and outgoing air extremely efficiently (90%).
• High Performance Glazing – Triple Glazed aluminum thermally broken, tilt-turn, fully sealed windows. In conjunction with these, motorised external non-combustible blockout shutters have been installed to satisfy the Bushfire Requirements of the site, but will also be controlled but the home automation system. Sensors will be installed to Northern and Western glazing (internally) whereby if the glazing warms above a set temperature the shutters will automatically close to stop the solar gain.
• Super Insulated Walls.
• Super Insulated Roofs.
• Further to the having super insulated wall and roof elements, it was important to ensure that thermal bridges are eradicated. Designing in the 50mm PIR Foam Panels to Walls & Roofs achieves this. As a result, external cladding and roof battens do not connect with internal timber frames walls and roof structure.
• LED Energy Efficient Lights throughout to minimise energy usage.
• 5kw Solar System being installed to harvest energy from the sun. This system will be monitored by the Home Automation System to record energy harvested and the peak times that occurred. The Home Automation System can then be used to prioritise when energy should be used to better utilize harvested energy. Home Appliances can be set to turn on in these peak times. The pool filtration will run and the pool can be heated by a high efficient Heat Pump during these times. The highly efficient Heat Pump will heat Hot Water during these times. On hot days, the small air-conditioning system will be run when energy is being harvested. The aim of the Pilot House is to be Net Zero on energy consumption. That is, to harvest as much energy that is consumed. Further to that, the aim is to try and utilise the harvested energy as its created due to different buy and sell tariff rates and Energy Management capabilities of the Home Automation System will aid in this.
• Highly Efficient Heat Pump Hot Water System which allows the utilisation of energy harvested from the PV solar system.
• Rinnai Gas Fire Place internally. Whilst the main driver to install this is for aesthetic/lifestyle reasons, the heater will be used to provide supplementary heating if required on very cold days. The Fire Place will be interfaced with the Home Automation system which will turn on (and off) the Fire Place if internal temperatures drop below a set level.
• Home Automation System has a number of Environmental advantages:
1. Energy Management – apart from monitoring and recording energy harvested by the PV Solar System, it will monitor every internal light and power circuit, providing valuable feedback to empower the occupants to make better decisions to reduce energy consumptions. It will also provide feedback to the occupants around when it is best to use harvested energy to run certain appliances, produce hot water, filter and heat the pool etc.
2. External Block-out Shutter Control to minimise solar gain by the shutter closing automatically when glazing temperature hit a set level. Likewise they will open when the heat load reduces.
• Hebel floor panels to Level 1 floor.
• 2.5R Acoustic Batts to all internal walls. R4 batts to whole of Level 1 floor.
• 100% Natural Ventilation – as the house is air-tight it requires 100% outside fresh air ventilation. This is achieve through the Heat Recovery Ventilator (HRV). Apart from working to achieve a constant inside air temperature, the HRV provides a high level of Air Quality. High quality HEPA filters are utilized to filter air-borne particles, pollens, toxins and other allergens etc, helping to provide the ultimate indoor environment which while is extremely advantageous the health of the occupants, it is life changer for suffers of Asthma, Allergy’s etc.
• An environment free of mould spores and bacteria is achieved not only through 100% Natural Ventilation but also through quality wall and roof panel construction. It is relatively unknown that the majority of homes in Australia, but mostly the southern states with greater temperature extremes, have condensation inside their homes walls and roofs. This provides the environment for mould and bacteria to grow. Utilising high quality breathable membranes externally and a high quality air-tightness layer internally ensures that whilst the house remains air-tight, moisture is still able to transfer through the building fabric.
• Low Voc Paints, Glues, Joinery Panels and Carpets are being used through the house to minimise toxins as much as possible.
• Measures to reducing the effects of EMF (Electromagnetic Frequency) Radiation are being implemented, mainly to the five bedrooms of the house. Radiation exists in high levels in most environments with the advent of technology, particularly homes. Levels are typically well above proven safe levels. EMF’s are produced from external sources such as Mobile Towers, Power Lines etc, from external Geological sources and from Internal Sources such as Wifi, internal power cabling etc. With the pilot home we are testing the effectiveness of some products from Geovital to greatly minimise EMF’s to bedrooms where it has been reported and logically acknowledged is the place where the body’s recovery needs to be maximised. Radiation shield mesh and paint are being installed to external bedroom walls. Shielded cabling is being used where required and Demand Switches are being installed (within the main switchboard) to all bedroom lighting and electrical circuits that will cut all current within those circuits when their is no demand upon then, i.e. at night when occupants are asleep.
1. Home Automation – apart from the added Environmental advantages already covered, the Home Automation system will integrate a lot of the building services and functions, such as:-
• Allows remote off site control and control via tablets such as iPads of all building services listed below.
• Integrates home audio and AV systems, therefore allows for a central control via iPad of all these appliances. • Controls lighting including dimming.
• Controls pool filtration, heating, spa and swim jets.
• Controls Irrigation to landscaping.
• Controls Gas Fire Place.
• Controls ventilation, heating and cooling systems.
• Controls external blackout and security shutters.
• Controls CCTV cameras (four in total).
• Controls access control with a touch key pad and records who and when access has been granted. Also allows for off site locking and unlocking of the house.
• Control the security system and will link “at home” and “away” modes with the opening and closing the door.
• Integrates Garage Door control and will link “at home” and “away” modes with the opening and closing the door.
2. Wood Fired Pizza Oven, spark arrested due to proximity of Bushland, with an adjoining built in outdoor kitchen. 3. Small pool with wet edge that is heated, has swim jets and doubles as a large spa if required.
