ItemA modelling method to assess the effect of tree shading for building performance simulation(International Building Performance Simulation Association, 2011)Increasing urban tree numbers is a simple but effective means to provide climate change adaptation to the urban environment by reducing the thermal load on buildings. To better communicate and value the importance of urban trees it is necessary to quantify these benefits and to understand the properties and processes that influence the magnitude of these benefits. For this we need verified and effective ways of modelling the trees in modelling software. This paper presents the results and problems encountered when trying to model trees effectively. The aim is to present our approach which was to treat the shade as a shading co-efficient on the wall. This allows for the consideration of the benefits of deciduous versus evergreen species. A modelling method to assess the effect of tree shading was developed and presented in this paper.

ItemComparing mixing ventilation and displacement ventilation in university classrooms(ZEMCH Network, 2018-01-29)There are two main types of mechanical ventilation systems: the mixing ventilation (MV) and the displacement ventilation (DV). The aim of this work is to compare their performance in terms of ventilation efficiency, air temperature, relative humidity, size-resolved particle concentrations, carbon dioxide (CO2) concentrations, and energy consumption. We performed a field investigation in two side-by-side classrooms installed with the two different ventilation systems. The energy consumptions were measured by i) a heat meter to measure the energy extracted by chilled water supplied, and ii) a power analyser to measure energy consumed by the ventilation fan. We also monitor indoor air dry bulb temperature, relative humidity, and CO2 concentrations in real-time for both rooms. It was found that the classroom with DV system consumed more energy. The unexpected high energy consumption can be attributable to the improved ventilation, CO2 and humidity control in DV room. Air temperature stratification were observed in DV room, but both room achieved similar volume-averaged temperate. We also found lower particle concentrations in both rooms compared to outdoor levels.

ItemPilot study on IEQ of an aged-care facility in Victoria(ZEMCH Network, 2018-01-29)Australian population is ageing. The proportion of Australian population over 65 years old has been increased and it is projected to be 25% in 2042. Although the Victorian Government has promoted ageing in place under home care package services, there is still a genuine need to provide more residential aged care services to satisfy the needs. The indoor environmental quality (IEQ) of residential aged care facilities is closely related to the health and well-being of residents living there. In this pilot study, the Adare Supported Residential Services (SRS) in Victoria is selected as the site for investigation. Some sensors are deployed in both communal areas and residents’ rooms to collect transient data on IEQ parameters, including carbon dioxide concentration, dry bulb temperature, radiant temperature, relative humidity and illumination level. Data collected is analysed and the links between outdoor environmental conditions and IEQ parameters are investigated. Limitations of this pilot study are discussed and recommendations for the full study are provided.

ItemNo Preview AvailableHow Could Sustainability Transition Theories Support Practice-Based Strategic Planning?(Springer, 2018-01-01)Theories of sustainability transitions aim to explain the processes, pathways and actors that are involved in transformations in technologies and practices. Whilst there is a growing body of research developing theoretical understandings, there has been less documented on how theories are utilised and applied by practitioners themselves. This chapter reports on a case study that investigated whether provision of targeted information on theories of sustainability transitions could strengthen organisational strategic planning. If planning is informed by transition theories, would this assist and strengthen organisational visioning, ambition and confidence? The research focuses on Moreland Energy Foundation Limited (MEFL), a community-based not-for-profit organisation working on sustainable energy and climate change action in Melbourne, Australia. During 2014–2015, MEFL developed a new strategic plan. As part of this process, theories of sustainability transitions were presented to the organisation’s Board and staff, to support the strategic planning and to investigate the theories’ roles in the planning process. It was found that inclusion of the sustainability transitions theoretical framework led to the organisation explicitly defining its shared ‘model of change’, reinforcing the organisation’s conceptualisation of its role as an ‘intermediary’ between grassroots and governments. The process demonstrated the potential impact of research-practice partnerships in strategic planning. However the findings also highlighted the continuing challenges of connecting research and practice.
