Net energy analysis of solar and conventional domestic hot water systems in Melbourne, Australia

It is commonly assumed that solar hot water systems save energy and reduce greenhouse gas emissions. Very rarely has the life-cycle energy requirements of solar hot water systems been analysed, including their embodied energy. The extent to which solar hot water systems save energy compared to conventional systems in Melbourne, Australia, is shown through a comparative net energy analysis. The solar systems provided a net energy saving compared to the conventional systems after 0.5 to 2 years, for electricity and gas systems respectively.<br /

Australian telecommuting : management communication strategies

This paper reports findings on the significance of management communication strategies to telecommuting, based on a survey of telecommuters at IBM Australia. With increased adoption of telecommuting, many strategies have been proffered to ensure that telecommuters have appreciable levels of job satisfaction. Low levels of job satisfaction can lead to unduly rapid employee turnover that is detrimental to business operation. The objective of this paper is to ascertain the perceptions of telecommuters at IBM Australia on a number of telecommuting practice measures, and to suggest how job satisfaction can be improved and maintained at high levels by giving greater attention to particular communication management strategies in Australia. Although the management communication strategies proffered in the literature appear to apply generally, this study concludes that a few aspects are distinctively applicable to the Australian environment. Those aspects should be specifically noted by those interested in benefiting from telecommuting practice. <br /

FM Puzzle: Sick Building and Sydney`s Open-plan Offices

Presents analytical findings of sick building situations in Sydney’s open-plan offices. Aims to ascertain facilities managers’ perceptions of sick building impacts on discrete aspects of workspace management, with a view to raising general awareness. A total of 100 open-plan offices in the Sydney CBD were studied, and collated data analysed using partial correlation. Significant associations were found between sick building syndrome and certain aspects. However, management control played moderating roles in some of the associations. Concludes that, with management control, sick building syndrome may be perceived as critical to only a limited workspace aspect. The implication is for sick building syndrome to be largely generalised as inconsequential to many aspects of work environment in Sydney, probably following the Hawthorne management ideology. © 2001, MCB UP Limite

Influence of Building Type on Post-Handover Defects in Housing

Clients’ lack of involvement in defining quality requirements for dwellings built by developers leads to a perception of poor quality at the time of purchase. The research presented in this paper aims to broaden previous research on defects by analyzing the defects that remain in the post-handover stage, which usually lasts 12 months after the handover period, and identifying the factors that influence the appearance of these defects, determining whether a significant difference exists in the quality of the two main residential building types built by developers: flats and detached houses. It also analyzes and discusses the areas and elements in which the defects were detected. The data were obtained from client complaint forms completed after the handover of 95 dwellings in Spain. The data were then statistically analyzed using a t-test analysis, a Pearson’s parametric correlation, and a chi-square test. The research reveals that clients detect more defects in flats than in detached houses. The lower quality of the materials used in flats and the tighter schedule to which flats are subject may cause these differences
