Abstract

Aims to compare the energy embodied in office buildings varying in height from a few storeys to over 50 storeys. The energy embodied in substructure, superstructure and finishes elements was investigated for five Melbourne office buildings of the following heights: 3, 7, 15, 42 and 52 storeys. The two high‐rise buildings have approximately 60 percent more energy embodied per unit gross floor area (GFA) in their materials than the low‐rise buildings. While building height was found to dictate the amount of energy embodied in the “structure group” elements (upper floors, columns, internal walls, external walls and staircases), other elements such as substructure, roof, windows and finishes seemed uninfluenced.

Abstract

The energy required to operate office buildings has been the focus of much research in the past three decades. There have been limited attempts to quantify the embodied energy consumed in construction. Some embodied energy studies have been relatively detailed. But the energy embodied in fixtures, fittings and furniture which is used by occupiers of buildings is rarely mentioned. The potential significance of the energy embodied in fixtures, fittings and furniture has yet to be established. Aims to establish the likely importance of the energy embodied in fixtures, fittings and furniture relative to other life cycle energy requirements of office buildings in temperate climates. Implementation actions are suggested for the optimisation of the energy embodied in fixtures, fittings and furniture used in buildings. Assists facility managers and businesses with their decision making with respect to the environmental impacts associated with energy use throughout the life cycle of their buildings.

Abstract

Embodied energy is the total amount of energy required to produce a product, and is significant because it occurs immediately and can be equal over the life cycle of a building to the transient requirements for operational energy. Methods for embodied energy analysis include process analysis, input‐output analysis and hybrid analysis. Proposes to improve the reliability of estimating embodied energy based on input‐output models by using an algorithm to extract systematically the most important energy paths for the “other construction” sector from an Australian input‐output model. Demonstrates the application of these energy paths to the embodied energy analysis of an individual commercial building, highlighting improvements in reliability due to the modification of energy paths with process analysis data. Compares materials and elements for the building, and estimates likely ranges of error.

Abstract

Purpose

The recurrent embodied energy (REE) is the energy consumed in the maintenance, replacement and retrofit processes of a facility. The purpose of this paper was to analyze the relationship of REE with the service life and life cycle embodied energy. The amount of variation in the reported REE values is also determined and discussed.

Design/methodology/approach

A qualitative approach that is known as the literature based discovery (LBD) was adopted. Existing literature was surveyed to gather case studies and to analyze the reported values of REE.

Findings

The reported values of REE showed considerable variation across referred studies. It was also found that the reported REE values demonstrated a moderate positive correlation with the service life but a very strong positive correlation with the life cycle embodied energy of both the residential and commercial facilities.

Research limitations/implications

This review paper pointed out the importance of the maintenance and replacement processes in reducing the life cycle energy use in a facility. Future research could focus on performing case studies to evaluate this relationship.

Practical implications

The findings highlight the significance of REE in reducing the life cycle energy impacts of a facility. As facility managers routinely deal with maintenance and replacement processes, they hold an important responsibility of reducing the life cycle energy.

Originality/value

The findings of the paper would motivate the facilities management professionals to prefer long service life materials and components during the postconstruction phases of a built facility.

Abstract

Australians were recently awarded the dubious honour of building the largest homes in the world. Our new homes are now seven percent larger than those in the United States and nearly three times larger than those in the United Kingdom. At the same time, the price of an average residential property is now five times what it was 20 years ago. Although incomes have risen over the same period, they have not kept pace with rising house prices. In terms of disposable income, the cost of housing has almost doubled. While traditional housing affordability is measured in terms of house prices and incomes, a broader and more encompassing perspective also indicates that we can no longer ‘afford’ to build houses as we have done in the past. The environmental impact of modern Australian housing is significant. Australians have resisted the need for increased urban density as their capital city populations grow and new houses have been built on the outskirts of the existing cities, encroaching on the greenwedge and agricultural lands, destroying and degrading existing fauna and flora. The houses built have increased carbon emissions because of their size, embodied energy and reliance on the motor car. This paper discusses the environmental ‘affordability’ of current Australian housing and argues that this must be considered alongside traditional affordability criteria so that a more holistic approach to the issues is adopted.

Abstract

Energy used in buildings is a major contributor to Australia’s energy consumption and associated environmental impacts. The advent of complex glazing systems such as double glazing, particularly in northern America and Europe, has partially closed a weak thermal link in the building envelope. In milder climates, however, building envelope features may not be as effective in life cycle energy terms, i.e. including the embodied energy of their manufacture. A net energy analysis compares the savings in operational energy to the additional requirements for embodied energy, in terms of the energy payback period and energy return on investment. The effectiveness of double glazing is determined for an Australian residential building. A wide range of building operation regimes was simulated. These results support the principle of installing double glazing in residential buildings in Melbourne, Australia, at least in terms of net primary energy savings.

Abstract

Architectural and engineering firms (design firms) have eschewed implementing quality assurance (QA) and other subsequent aspects of quality such as continuous improvement. Their reluctance to embrace QA has been found to be a contributing factor in the production of poor quality contract documentation. Missing, conflicting and erroneous information contained within contract documentation are major sources of rework and customer dissatisfaction in construction projects. If design firms are to significantly improve the quality of the service they provide, they should implement ISO 9000 quality management and assurance standards. By implementing such standards, it is suggested that design firms will be able to contribute more effectively to the value adding process in the construction supply chain. It is argued that the service offered by design firms should be viewed as a key component of value that drives its success. Therefore, because rework is a major source of dissatisfaction in projects, a case study was used to determine how its occurrence inhibited value creation and thus the quality of service provided. From the case study findings, the need for design firms to implement ISO 9000 quality management and assurance standards so as to improve their service quality is discussed.

Abstract

Residential building construction activities, whether it is new build, repair or maintenance, consumes a large amount of natural resources. This has a negative impact on the environment in the form depleting natural resources, increasing waste production and pollution. Previous research has identified the benefits of preventing or reducing material waste, mainly in terms of the limited available space for waste disposal, and escalating costs associated with landfills, waste management and disposal and their impact on a building company's profitability. There has however been little development internationally of innovative waste management strategies aimed at reducing the resource requirement of the construction process. The authors contend that embodied energy is a useful indicator of resource value. Using data provided by a regional high‐volume residential builder in the State of Victoria, Australia, this paper identifies the various types of waste that are generated from the construction of a typical standard house. It was found that in this particular case, wasted amounts of materials were less than those found previously by others for cases in capital cities (5‐10 per cent), suggesting that waste minimisation strategies are successfully being implemented. Cost and embodied energy savings from using materials with recycled content are potentially more beneficial in terms of embodied energy and resource depletion than waste minimisation strategies.

Abstract

Purpose

This commentary aims to reveal how a steering committee has effectively responded to advancing accessibility to harm reduction resources, hepatitis C virus (HCV) policy and health strategies within adult prison settings in New South Wales (NSW).

Design/methodology/approach

By reviewing the audit approach taken by the of the Justice Health and Forensic Mental Health Network and Corrective Services New South Wales Harm Reduction Reference Group (JHFMHN/CSNSW HRRG), this commentary emphasizes the committee’s success in identifying contemporary harm reduction issues that affect people in custodial settings. This commentary is a compilation of data gathered through the 2018 JHFMHN/CSNSW HRRG audit and corresponding program materials. Conclusions regarding the effectiveness of the working group’s audit were drawn by critically appraising the JHFMHN/CSNSW HRRG’s Final Audit Report (JHFMHN and CSNSW, 2018) with reference to current harm reduction literature.

Findings

The HRRG has provided leadership, professional representation and strategic advice on the development, implementation, monitoring and evaluation of best practice harm reduction strategies in prison settings. The HRRG developed and maintained networks and information exchange between the state-wide HCV health network, corrections services and the NSW harm reduction sector at large. Public health partnerships and advocacy that involve all key players, such as the HRRG, will continue to be crucial to remove barriers to enhancing HCV harm reduction measures especially in NSW prison settings.

Social implications

Strategies such as primary prevention and treatment can mitigate the spread of HCV in the custodial system. This audit of access to harm reduction resources was conducted on behalf of the diverse group of professionals, scholars and stakeholders comprising the HRRG. This audit and other advocacy efforts of this committee can facilitate future access to quality healthcare and the necessary policies required to support a healthier prison population at large.

Originality/value

Collaborating with health authorities, researchers and social service workers can enable prison health-care systems to be guided by wider health workforce programs and public health standards. This collaboration can reduce the professional isolation of custodial health-care staff and promote a balanced approach to harm reduction policies by ensuring an equitable focus on both health and security imperatives.

Abstract

Purpose

Recently, there has been a shift toward the embodied energy assessment of buildings. However, the impact of material service life on the life-cycle embodied energy has received little attention. We aimed to address this knowledge gap, particularly in the context of the UAE and investigated the embodied energy associated with the use of concrete and other materials commonly used in residential buildings in the hot desert climate of the UAE.

Design/methodology/approach

Using input–output based hybrid analysis, we quantified the life-cycle embodied energy of a villa in the UAE with over 50 years of building life using the average, minimum, and maximum material service life values. Mathematical calculations were performed using MS Excel, and a detailed bill of quantities with >170 building materials and components of the villa were used for investigation.

Findings

For the base case, the initial embodied energy was 57% (7390.5 GJ), whereas the recurrent embodied energy was 43% (5,690 GJ) of the life-cycle embodied energy based on average material service life values. The proportion of the recurrent embodied energy with minimum material service life values was increased to 68% of the life-cycle embodied energy, while it dropped to 15% with maximum material service life values.

Originality/value

The findings provide new data to guide building construction in the UAE and show that recurrent embodied energy contributes significantly to life-cycle energy demand. Further, the study of material service life variations provides deeper insights into future building material specifications and management considerations for building maintenance.
