LIGHTING Philips Dynalite Dimension - Smart Lighting system, app (smart phone & motion sensor) control lighting system that turns-on and off based on presence, dimming options, security and automatic timer to optimize and personalize lighting usage thus minimizing energy use. Light bulbs are based on Philips range of LED bulbs, LEDtube and downlight systems (CorePro, Master LEDSpotLV & Master LEDTube series bulbs/tubes) with wattage of 5.5 to 7W with 1205 & 1533 kWh (respectively) per annum compared to 35W 7665 kWh per annum energy use for halogen bulb each.
ELECTRICAL APPLIANCES & COMPUTERS High WELS star-rating for reduced water consumption and high energy star RATING ELECTRICAL applianceS for reduceD energy consumption. Epeat rating for computer recyclibility.
SERVICES To achieve sustainable and net zero energy house, the following objectives will be the driving forces behind the choices for the systems used for services i.e. water, heating, lighting and electricity. 1) 2) 3) 4) 5)
Conserve water resources Reduce building operating energy cost Reduce household energy consumption Renewable energy sources Comfort
Water use Harvesting rainwater through 2 x 3000L rainwater tank connected through network of downpipes and connected the house water pipes for shower, washing etc. The tanks are also connected to the main water supply with automatic changeover when tank water level drops to a set low level that triggers the flow of water from main water supply. To avoid complication of compliance, drinking water is piped directly to kitchen sink with a dedicated tap for drinking water. Overflow of rainwater will be directed to the main storm water drain. Rainwater is also used for the gardenâ&#x20AC;&#x2122;s drip irrigation system. To conserve water further, a dual flushing system recycles the grey water for use of flushing toilets. The grey water from bathroom and laundry will be piped to an underground grey water tank with a grey water filter installed. When flushing occurs, water from this tank will be pumped for use. The owner will also have an option to have a garden/herbs planter installed connected to the grey water if so desired. Careful selection of high WELS rating bathroom taps and kitchen fixtures ensures low flow water into these fixtures thus reducing the amount of water use. Additionally, selected water conscious appliances such as dishwasher and washing machine intelligently measure washing loads to optimize water use, On-site power generation Use of solar as the primary energy source supply for the house through photovoltaic system. Refer to Zero Carbon House page and material schedule for specifications. Integrated solar thermal hot water and hydronic space heating system Integrated solar thermal hydronic heating and hot water system maximizes the use of thermal solar system through the evacuated solar tubes for space heating and hot water for washing and showering. The 2 systems (heating and hot water) uses the same pipe network as well as sharing the same enlarged 500L main thermal storage tank to provide continuous hot water supply as well as heating the heating radiators installed in each rooms and main family spaces. The thermal storage is also gas boosted if temperature dips below a certain level for continuous supply of hot water and radiant heating via radiators. Refer to material schedule for system specifications. Mechanical ventilation with heat recovery With increased airtight building envelope, the air within the house is circulated and ventilated through an air-to-air heat exchanger (MVHR) that replaces the stale air with fresh air external of the house. Additionally, the heat exchanger recovers the heat from the stale air and recirculate the air back into the rooms thus reducing the cost of heating (and cooling). Energy efficient and smart lighting system Connected LED lighting allow reduced energy consumption through LED technology as well as control on net-connected bulbs which allow individual on/off, timer and dimming function on each bulb. Additionally, motion sensor and timer functions will further reduce energy consumption by only turning on lighting as and when needed.
SITE ANALYSIS & DESIGN REPORT Sitting, orientation and environmental/climatic response The property is a corner block and aligned in east-west direction with existing houses on west and north facing sides. The block is bounded by two suburban street i.e. Benjamin Street and Callery Crescent. To maximize the view towards the open space, solar insolation and away from the neighboring south wall, the house is oriented towards north. Mature deciduous trees at the northern corner and south west of the block provides natural shading for hot summer sun yet provide full access to the sun during winter when the leaves shed. Additionally, the trees provide windbreak from the northerly winter prevailing breeze. As part of landscaping plan, evergreen scrubs (< 1 m height, for microclimate), deciduous trees (< 3m height) as well as deciduous creepers (for summer shade) is recommended along the north facing pergola. Scrubs is also suggested (< 2m height) to be planted along the south and east facing walls to provide stable temperatures in summer and winter while allowing cooler breeze to pass through during summer. The living (and dining) is arranged north facing to maximize daylighting. The kitchen is east facing to receive the morning sun. Two of three bedrooms are south facing with another north facing. Shadings is required for north facing windows and openings. North facing roof has an overhang of 500 mm as eaves. A pergolas with fix angle (30o slats provides summer shading for the large opening (bi-fold door) in the living room as well as Bedroom 1 window. High operable windows are arranged for south facing bedrooms and bathroom/toilet for privacy from adjacent street and minimal glazing strategy to reduce heat loss in winter. These windows can be opened for (cross) ventilation. There’s no openings on west facing to avoid hot summer sun. Daylighting for internal passage is achieved through tubular skylights (e.g. SOLATUBE). North facing rooms and kitchen (east facing) have ample openings (windows and bi-fold door) for daylighting. The site topology is generally flat throughout and suitable for concrete slab-ongrade foundation and concrete flooring for thermal mass attribute. The building construction method is Autoclaved Aerated Concrete (AAC) veneer walls (high R-value) fixed to timber frame. Painted Modakboard© (composite board) are used for interior wall and ceiling on timber stud frame and weatherproof paint on exterior wall. Roof is constructed using prefabricated and custom design engineered lumber, LVL (laminated Veneer Lumber) trusses. Insulated roof panels from Kingspan© fixed to trusses. Roof is graded to 1: 1.29 to achieve 37.7o Melbourne’s optimum solar angle for photovoltaic array.

Initial Star Rating and points: Floors:
Change to Stars / points:
Key Change : Concrete slab on grade as floor construction with carpet covering on floor Reasons : The concrete floor becomes thermal mass for the interior house envelope. Reduce energy use in heating and cooling of the house during winter and summer. The carpet covering extended the performance of the concrete floor during winter. Improvement : Increase points score and star rating of the house. Walls: Change to Stars / points: Key Change : Changed to reverse brick veneer wall construction. Reasons : The brick wall becomes thermal mass for the interior house envelope. Reduce energy use in heating and cooling of the house during winter and summer. Improvement : Increase points score and star rating of the house. Ceilings: Change to Stars / points: Key Change : Vented ceiling. Added 2 layers of reflective foil facing the air surfaces, one installed just underneath the roof and another just above the insulation material. Reasons : Radiant heat from the sun heating during the day radiates back to the house during the evening. Reflective foil will radiates back the heat to the roof thus making the attic insulation more effective. In consequence less energy required for cooling the house. Attic venting improves the performance by removing the hot air that circulates in the attic during summer as well as removing moisture built up during winter that can deteriorates and decrease insulation performance. Improvement : Increase points score and star rating of the house. Windows (and Skylights if relevant): Change to Stars / points: Key Change
: Skylight Large bi-fold glazed door for northern opening Fixed windows for east facing wall Small south facing OPERABLE windows Reasons : Skylight â&#x20AC;&#x201C; daylighting for interior passage. Large northern opening can assist heating of concrete floor (thermal mass) during winter thus improving heating performance. South facing window for cross ventilation path (for cool summer prevailing wind). Minimize south glazing to prevent heat loss during winter. Improvement : Increase points score and star rating of the house. Skylight is less than 2, no points taken. Skylight can increase total glazing surface area thus increasing heat loss in winter. Air Leakage and Design Features: Change to Stars / points: Key Change Reasons
: Sealing all gaps : Sealing all air leaks will create airtight building envelope thus maintaining the performance of insulation.
Improvement : Increase points score and star rating of the house. Final Star rating and points: 6 star rating with 79 points
