Sustainable retrofit potential in lower quality office stock in the central business district

Given the relationship between energy consumption, greenhouse gas emissions and climate change, the built environment has significant potential to lessen overall emissions. With around half of all greenhouse gas emissions attributed to the built environment; it has a significant role to play in mitigating global warming. With large percentages of office stock structurally vacant in some city centres and only 1 or 2% of new buildings added to the total stock each year; the scope for reductions lay with adaptation of existing buildings. The stock with the highest levels of vacancy and obsolescence offers the highest potential of all.

Many cities are now aiming to become carbon neutral. Successful retrofit demands that social, technological, environmental, economic and legislative criteria are addressed. Buildings have to meet user and community needs. City centres comprise a range of different type of office stock with regards to age, size, location, height, tenure and quality. All buildings present challenges and opportunities with regards to retrofit and sustainability and integrating retrofit measures that reduce energy, water and resource consumption.

Using a selection of low grade office buildings to develop retrofit profiles, this paper addresses the questions; (a) what is the nature of retrofits in relation to low quality office building stock in the Central Business District (CBD) and, (b) what is the extent and scope for sustainable retrofits to low quality office buildings. Using Melbourne CBD retrofit events of low quality office buildings were analysed between 1998 and 2008 to identify the scope and extent for integrating sustainability into retrofits projects.

Building the capacity of family day care educators to promote children’s social and emotional wellbeing : an exploratory cluster randomised controlled trial

Background: Childhood mental health problems are highly prevalent, experienced by one in five children living in socioeconomically disadvantaged families. Although childcare settings, including family day care are ideal to promote children’s social and emotional wellbeing at a population level in a sustainable way, family day care educators receive limited training in promoting children’s mental health. This study is an exploratory wait-list control cluster randomised controlled trial to test the appropriateness, acceptability, cost, and effectiveness of “Thrive,” an intervention program to build the capacity of family day care educators to promote children’s social and emotional wellbeing. Thrive aims to increase educators’ knowledge, confidence and skills in promoting children’s social and emotional wellbeing.
Methods/Design: This study involves one family day care organisation based in a low socioeconomic area of Melbourne. All family day care educators (term used for registered carers who provide care for children for financial reimbursement in the carers own home) are eligible to participate in the study. The clusters for randomisation will be the fieldworkers (n = 5) who each supervise 10-15 educators. The intervention group (field workers and educators) will participate in a variety of intervention activities over 12 months, including workshops; activity exchanges with other educators; and focused discussion about children’s social and emotional wellbeing during field worker visits. The control group will continue with their normal work practice. The intervention will be delivered to the intervention group and then to the control group after a time delay of 15 months post intervention commencement. A baseline survey will be conducted with all consenting educators and field workers (n = ~70) assessing outcomes at the cluster and individual level. The survey will also be administered at one month, six months and 12 months post-intervention commencement. The survey consists of questions measuring perceived levels of knowledge, confidence and skills in promoting children’s social and emotional wellbeing. As much of this intervention will be delivered by field workers, field worker-family day care educator relationships are key to its success and thus supervisor support will also be measured. All educators will also have an in-home quality of care assessment at baseline, one month, six months and 12 months post-intervention commencement. Process evaluation will occur at one month, six months and 12 months post-intervention commencement. Information regarding intervention fidelity and economics will also be assessed in the survey.
Discussion: A capacity building intervention in child mental health promotion for family day care is an essential contribution to research, policy and practice. This initiative is the first internationally, and essential in building an evidence base of interventions in this extremely policy-timely setting.

Building capacity in sexuality education : The Northern Bay College experience : Report of the first phase of the sexuality education and community support (SECS) project

The Sexuality Education and Community Support (SECS) project aims to introduce a P-12 approach to sexuality education at Northern Bay P-12 College (NBC) through a collaborative partnership process between the schools within the College and local, regional, and state health and education agencies and has set out to change current sexual health education practice in the College and assist other schools in the region to do the same. The Project’s goal is a ‘sustainable, responsive, whole school, regionally consistent, best practice sexuality education’. During this first or establishment phase of the SECS project strategies have been implemented to begin the process of building capacity in sexuality education at NBC. These strategies are aimed at developing a sustainable approach during the next three and a half years.

Sustainable management of real estate : is it really sustainability?

This paper investigates from a management perspective exactly what building owners and managers of commercial real estate are actually doing in the guise of sustainability. This research investigates key owners of real estate portfolios in Australia and New Zealand, and examines what they perceive sustainability to mean to their commercial real estate portfolios and their level of implementation. The research uses a qualitative framework in order to gain an understanding of owners’ perceptions of sustainability. The findings reveal that owners perceive sustainability to be very important to the longevity of their portfolios. However, at present, sustainability factors are limited to resource efficiency measures in their real estate portfolios. Consequently, this research questions whether current interpretation and implementation of sustainability in commercial real estate is merely ‘changing the name’ of best practice management to ‘sustainability.’

On the acoustic performance of a precast panel system made from environmentally sustainable concrete : application in sports hall buildings

The use of green building materials and products promotes conservation of non-renewable resources and help reduce associated environmental impacts. This article reports the acoustical performance of a precast panel system made largely from concrete waste material. Two major applications for such panels that are being investigated currently include walls and claddings to industrial and commercial buildings and sound barriers for urban freeways. In this study, the application of the concrete panels for optimizing reverberation time (RT) in sports halls is tested using numerical simulations. As an innovative approach, additional layers are added to the precast panels to improve their appearance. The absorption coefficients of the concrete panel improved significantly with the architectural finish. The material can be tuned according to the required peak frequency. The architectural finish helped reduce the RT for frequencies above 500 Hz. Its application to different types of ceilings revealed that the RT of curved ceiling reduced up to 40% compared to flat and hybrid ceiling. A comparison of wall and ceiling modifications in small, medium and large sports halls showed that medium-sized halls have better acoustical performance compared with small and large halls with ceiling as well as wall treatment.

Households' perceptions on sustainable home behaviour and improvements in Australia

The consumption of energy in the residential building is a major contributor to Australia's stationary energy greenhouse gas emissions. With the aim of investigating the householders' motivations and perspectives on sustainable home improvements, this study, by using an online survey instrument, collected more than 500 sets of questionnaire data from households in the state of New South Wales, Australia. Through statistical analysis of the data collected, this research has found that construction cost and government incentive were considered as major influence factors on achieving energy efficient residential building development, and the lower bills from reduced energy and water consumption were considered as the most important benefits from the households' perspectives. The research also found that although many households exhibited a high level of awareness or had implemented some sustainability improvements, the total number of potential improvements scored poorly. A suggestion, based on these research findings, is that the government should promote the reasons and benefits for sustainability home improvements that are identified in this research paper, and try to reduce material costs and improve government incentives.

South west Victoria 2012-2050 : are the settlements sustainable?

Over the past few decades coastal cities around the world have grown at an incredible rate. With this growth have come major challenges relating to land use planning, social relationships, economic development, bio diversity and the ecological footprint. The following paper selects three regional coastal towns (Warrnambool, Portland and Port Fairy) situated in the Australian state of Victoria, and addresses the issues of: increasing population and population density, open space requirements, residential density issues, public transport coverage, employment and employment density, a shifting economic climate, environment and climate change, water quality issues and building energy consumption with subsequent C02 emissions. Through a series of simulations the nine issues for each of the three cities will be examined from 2012 through to 2030. The goal is to highlight the current and simulated future impacts of the selected issues and propose solutions that could mitigate those impacts.

The contribution of Building Information Modelling (BIM) to Green Building Design and Assessment in Abu Dhabi "ESTIDAMA"

Estidama is a mandatory Green Building code in Abu Dhabi by which the compliance of building design is being assessed. This paper examines the current design and assessment approaches for Green Buildings to identify the reasons that lead to delay defects and it investigates a new approach for improvement. The available literature provides a realistic understanding to the problems and shows the road to some potential solutions. The identified problems were mainly attributed to the manual assessment with too much human interference. The piled documents with limited resources left the assessment system too slow to handle the whole projects within the greater Abu Dhabi engendering high risk of the commitment to review mistakes. Therefore, this paper investigates the potentiality of automating several stages via the use of Building Information Modeling (BIM) into the assessment process. Different experienced participants from all aspects within the construction industry were interviewed to contribute to the research. Also, a close question questionnaire was distributed to examine the current practice in Abu Dhabi to compare it with the initial findings. The findings point out significant requirements to adopt BIM in the assessment process, such as the availability of proper contracts form to shape the relationship between BIM parties and the readiness of the current system. Hence, the authors suggest a new model that integrates BIM capabilities within the system to accelerate the process and reduce human involvement.

Greenhouse affect : the relationship between the sustainable design of schools and children’s environmental attitudes

This study aims to determine if primary school children’s environmental attitudes can be predicted by whether their school had been designed or adapted for sustainability. A New Ecological Paradigm (NEP) scale for children was adopted to measure attitudes, with supplementary questions added to align this scale to the Australian context of the study. In addition, the original adult NEP scale was used to determine relationships between children’s environmental attitudes, their School Design and their Parents’ and Teachers’ Environmental Attitudes. Data collected from grade 4, 5 and 6 primary school children, their parents and teachers were analysed via three multiple regressions. The results indicate that sustainable design in schools improves the environmental attitudes of children towards perceptibly green building features, such as solar panels, the use of recycled water, natural daylighting and outdoor classrooms including food-producing gardens.

Lessons in building capacity in sexuality education using the health promoting school framework: from planning to implementation

Purpose – The health promoting school model is rarely implemented in relation to sexuality education. This paper reports on data collected as part of a five-year project designed to implement a health promoting and whole school approach to sexuality education in a five campus year 1-12 college in regional Victoria, Australia. Using a community engagement focus involving local and regional stakeholders and with a strong research into practice component, the project is primarily concerned with questions of capacity building, impact and sustainability as part of whole school change. The paper aims to discuss this issue. Design/methodology/approach – Using an action research design, data were collected from parents, students, teachers and key community stakeholders using a mixed methods approach involving surveys, interviews, document analysis and participant observation. Findings – Sexuality education has become a key school policy and has been implemented from years 1 to 9. Teachers and key support staff have engaged in professional learning, a mentor program has been set up, a community engagement/parent liaison position has been created, and parent forums have been conducted on all five campuses. Research limitations/implications – The translation of research into practice can be judged by the impact it has on teacher capacity and the students’ experience. Classroom observation and more longitudinal research would shed light on whether the espoused changes are happening in reality. Originality/value – This paper reports on lessons learned and the key enabling factors that have built capacity to ensure that sexuality education within a health promoting, whole school approach will remain sustainable into the future. These findings will be relevant to others interested in building capacity in sexuality education and health promotion more generally.

Building allied health workforce capacity: a strategic approach to workforce innovation

Objective The aim of the present study was to identify areas where allied health assistants (AHAs) are not working to their full scope of practice in order to improve the effectiveness of the allied health workforce.

Methods Qualitative data collected via focus groups identified suitable AHA tasks and a quantitative survey with allied health professionals (AHPs) measured the magnitude of work the current AHP workforce spends undertaking these tasks.

Results Quantification survey results indicate that Victoria’s AHP workforce spends up to 17% of time undertaking tasks that could be delegated to an AHA who has relevant training and adequate supervision. Over half this time is spent on clinical tasks.

Conclusions The skills of AHAs are not being optimally utilised. Significant opportunity exists to reform the current allied health workforce. Such reform should result in increased capacity of the workforce to meet future demands.

What is known about the topic? Increasing skill shortages across Australia’s health workforce necessitates that the capabilities of all healthcare team members should be used optimally. AHA roles are an important and growing response to current health workforce needs. Increasing workforce capacity will ensure the right health workers are matched to the right task by skill, experience and expertise.

What does this paper add? This paper presents a model that assists services to identify tasks suitable for delegation to an AHA by an AHP. The model is unique because it describes a process that quantifies the need for AHAs and it has been successfully implemented in rural, regional and metropolitan health services in Victoria.

What are the implications for practitioners? Working collaboratively, with executive support, will lead to a sustainable and integrated approach to support workforce capacity building. Altering the skill mix of healthcare teams through increasing the role of AHAs has benefits for AHPs, patients and the healthcare system.

A pixel-based approach to estimation of solar energy potential on building roofs

Precise estimation of solar energy on building roofs plays a critical role in sustainable development and renewable energy consumption of high-density human habitats. Conventional solar radiation models based on costly Light Detection and Ranging (LiDAR) data are only adequate for existing buildings, not for future construction areas. In this paper, a pixel-based methodology is constructed for estimating solar energy potential over roofs. Buildings with flat roofs in a newly planned construction area are chosen as a case study. The solar radiation at a certain cell is mathematically formulated in the pixel unit, and its yields over a certain time period are calculated by considering multiple instantaneous solar irradiances and are visually presented by image processing. Significant spatial and temporal variations in solar radiation are measured. Within the study area, the maximum and minimum annual radiation yields are estimated at 4717.72 MJ/m2/year and 342.58 MJ/m2/year respectively. Radiation contour lines are then mapped for outlining installation ranges of various solar devices. For each apartment building, around 20% of roof areas can obtain 4500 MJ/m2/year or more solar radiation yields. This study will benefit energy investors and urban planners in accurately predicting solar radiation potential and identifying regions with high radiation over building roofs. The results can be utilised in government policies and urban planning to raise awareness of the use of renewable energy sources.

Capacity building for post disaster construction and demolition waste management: a case of Sri Lanka

Purpose – The purpose of this paper is to present a theoretical framework for capacity building in post disaster construction and demolition (C&D) waste management at a national level to address the identified capacity gaps in managing disaster waste resulting from natural hazards.

Design/methodology/approach – Data were gathered through pilot interviews, case studies and expert opinion surveys representing government, non-government and other sector organisations involved in post disaster waste management.

Findings – The study revealed unavailability of a single point of responsibility and provision for disaster waste in existing policies and capacity constraints in prevailing peace time solid waste management practices which were identified as major capacity gaps. Establishment of a regulatory body and enforceable rules and regulations with necessary levels of capacities was identified and presented in a theoretical framework comprising of seven identified areas for capacity building in post disaster waste management.

Research limitations/implications – This study is limited to disaster C&D waste as debris generated from totally or partially damaged buildings and infrastructure as a direct impact of natural hazards or from demolished buildings and infrastructure at rehabilitation or early recovery stages. Waste generated during reconstruction phase of post disaster management cycle is not considered as disaster C&D waste for purposes of this study.

Originality/value – The research enabled analysis of existing capacities and presents approaches for capacity building for identified gaps in post disaster C&D waste management to attain sustainable post disaster waste management for future resilience.
