Why we're involved?
Our mission is to drive a sustainable built environment committed to environmental sustainability and climate ready housing. Our winning entry in the 2017 BDAV 10-Star-Challenge inspired us to take the next step and work with partners to build a real life example. We wanted to provide a tangible experience for the public to experience first-hand, so that they may come to understand the difference and appreciate the substantial benefits of a truly energy efficient home. We believe everyone should have access to a certain standard of sustainability and well-being within their home, regardless of their budget or means. For our 15 years in compliance, we also understood for the ‘Ten Star Home’ to be future thinking, this impact of such innovation could be multiplied using industry relationships with people also wanting to make a difference to health in the built environment.
How we're assisting in resilient built environments.
We facilitate education, upskilling knowledge in energy NCC compliance, design and have been supporting Architects, Developers, Builders and home owners to improve buildings since we first started. We have invested in technology and artificial intelligence platforms to assist the speed at which we can simulate millions of runs through performance software for analysis. Whilst the automation of this is a function of our business, so too is the personal one-to-one nature of consulting assistance, ensuring each optimisation is customised to how the building is best operated by the occupant. We’ll never cease our personalised approach because it leads to a lot of savings for the environment in lowering excess in construction.
Adding health and amenity for the user.
While this home strives to establish a benchmark for environmental sustainability, we believe in a holistic approach with human experience at its heart. We designed the home around societies increasing need for connection – to people, nature and technology, nourishing occupant’s well-being and health.
We are planning to performance test this home (pre and post construction) to ensure that we meet our own targets for indoor air quality, air infiltration, mental, physical and environmental health, minimisation of energy consumption and waste.
Our high-performance housing also continues to feedback into government research, community and partnerships through being a demonstration of automation systems, new technologies and responsive operation for the maximum performance possible of the building. It will continue to operate through the coming few years so that we can see how houses respond to many effects of climate change and therefore giving real data to adopt in carbon neutralising strategies going forth.
Empowering owners choices.
We very much value any one to one conversations with clients on how they wish see themselves within a resilient and proactively adaptable climate ready future. Often, we get feedback after our conversations from clients that find they are able to categorise and schedule their ultimate sustainable wish list so it can be scheduled over many years. This is also responsive to the typical changes we experience in families as children grow, spaces adapt or needs change in terms of privacy and use.
The information exchange also goes both ways, by us listening to what clients and home owners are needing, then reflecting this in how our future ready houses operate it means that we are grounding our work in a very contextually rich understanding of how South Australian’s want to live. This obviously also reflects the different ‘social cultures’ around Australia as they can all be distinguished in a different way. We’re hoping that having clear, transparent communication on all our projects means that the clients come on a journey of reflection and learning with us.
Studio / Class 1
Working closely within SUHO, the Studio, Compliance, Research and Innovation groups worked towards ensuring that our knowledge of the NCC and class 1 construction were utilised within this build. Through our compliance work we were able to optimise the house to perform at the highest level possible whilst also analysing the best construction method for the design using Roborater. The technology simulated millions of times, the best configuration of materials, insulation and construction of walls, floor and roof based on the NatHERS ratings system. From here we pushed the innovation beyond a ten star rating and included strategies similar to passive house standards which allow consideration of air-tightness and moisture to ensure that our building will last longer than a generic home.
Auditing and Blower Door Testing
15 - 25% of winter heat loss is due to unintentional air leakage (www.yourhome.gov.au). During an air tightness test, a house is put under positive or negative pressure, exacerbating the air leakage pathways enabling easy detection of leaks by feel, thermal camera or hand held smoke machine to name a few. We can also obtain a number - an air leakage score that enables us to compare against Australian and international benchmarks and make educated decisions around either tightening or ventilation strategies. Air tightness testing in Australia is governed by Australian Standard NZS ISO 9972:2015. To make the HRV effective you'll need to target 3ACH / 3m3/h/m2 or less. The ten star house contains MHRV, moisture analysis and air-tightness strategies were planned ahead of construction commencing to ensure that we are hitting our target. Build tight, ventilate right!
Energy Efficiency and compliance
Indoor Environment Quality
Given that Australian’s spend approximately 90% of their lives indoors, the indoor environment quality is critical to occupant’s wellbeing (https://www.environment.gov.au/protection/air-quality/indoor-air). Both levels of natural daylight and the thermal comfort of a dwelling are crucial to a building being comfortable for the inhabitants. At SUHO we provide additionally modelling services to assist in optimising designs. Firstly testing how much natural daylight is available in each room, this allows for discussion with the design team on optimising the location, size of windows and location and side of shading elements. Temperature analysis can also be undertaken to provide a guide on how a building will perform thermally. This then guides conversation of how adjusting the building fabrics and glazing specification impacts the thermal comfort of a building. Simulations for both of these key indoor environment quality parameters were undertaken during the design phase of the 10 star house.
Solar Panel Optimisation
Solar analysis can be undertaken to optimise the size and layout of a solar panel array. The optimisation process allows for the number of panels and there location to be set out on the roof, making sure that any overshadowing is minimised wherever possible. This process was used during the design of the 10 star house to determine the most applicable size and locations of the PV array.
As there are often no specific town planning requirements in South Australia for ESD, the Sustainability Statement is the perfect opportunity to showcase the sustainable design initiatives to your local council to assist in gaining planning approval. The sustainability statement showcases key elements of a design in 9 categories; Management & Waste, Energy, Water, Indoor Environment Quality, Materials, Land Use & Ecology, Transport, Emissions and Innovation). The consultants also review the local development code and discuss the design responses with the design team, also providing advice on cost-effective measures that will benefit the project from a commercial, comfort and planning approval perspective. Other town planning services include sustainable management plans, water sensitive urban design assessments, waste management plans and green travel plans.
