A perspective on chaos theory: Potential applications to intelligent buildings

Mathematical models have been vitally important in the development of technologies in building engineering. A literature review identifies that linear models are the most widely used building simulation models. The advent of intelligent buildings has added new challenges in the application of the existing models as an intelligent building requires learning and self-adjusting capabilities based on environmental and occupants' factors. It is therefore argued that the linearity is an impropriate basis for any model of either complex building systems or occupant behaviours for control or whatever purpose. Chaos and complexity theory reflects nonlinear dynamic properties of the intelligent systems excised by occupants and environment and has been used widely in modelling various engineering, natural and social systems. It is proposed that chaos and complexity theory be applied to study intelligent buildings. This paper gives a brief description of chaos and complexity theory and presents its current positioning, recent developments in building engineering research and future potential applications to intelligent building studies, which provides a bridge between chaos and complexity theory and intelligent building research.

Change in construction: a critical perspective

Change within the construction sector has been a central concern of governments and a select few private-sector clients for a considerable time. The discourse of change emanating from organizations concerned with reform in the construction sector reflects these ongoing concerns for change in the sector. The underlying assumptions of the content of change and appropriate change mechanisms in the UK are critically examined and challenged. In particular, the limitations of measurement and best practice are explored. The allegiance to approaches based on measurement and best practice is acontextual, unreflective and insufficient in providing wholly reliable explanations for the relationship between practice and performance. Claims for the use of measurement and best practice by the reform movement must therefore be understood to have limitations and their use approached with caution. The emphasis on best practice is also understood to direct attention away from understanding the legitimacy of current practice and change within the UK construction sector. An agenda for change in the UK construction sector will need to engage with and be more reflective of current managerial practice and past change initiatives. Contextual approaches such as structuration theory offer a way in which to underpin a research framework that could support the reform movement in setting such an agenda.

Developing an engaging virtual action learning programme for SME managers – A UK perspective

In this paper we present results from an EU-funded project with the aim of examining the adaptation of e-learning to meet the needs of managers in different contexts. A set of design considerations is elucidated. These principles were derived from an analysis of five completed projects. This was followed by focus group discussion in the UK to test the principles derived.. These focus group were planned so as to gain greater clarity in the design of e-learning programmes aimed at UK-based SME leaders and managers. This paper starts by looking at the importance of SME management development for the economic wellbeing of the community and goes on to review research into issues in engaging managers in development activities. The results of a review of an earlier experimental programme (ESeN) are presented as it formed part of the process which led to the identification of theoretical design principles then tested in the focus groups. Finally, recommendations are presented for SME e-learning providers as well as areas for further research.
