Routine maintenance and sustainability of existing social housing

Improving the sustainability of the housing stock is a major challenge facing the UK social housing sector. UK social housing accounts for approximately 18% of total UK housing and generates maintenance costs in the region of 1.25 billion pounds per annum. The extent to which routine maintenance can be used as a vehicle to improve the overall sustainability (social, environmental and economic) of existing social housing is one focus of a 5 year EPSRC funded research programme. This paper reports the findings of a questionnaire survey examining current social housing maintenance practices and attitudes towards sustainability. The research found that, whilst the stock condition survey is the favoured format for determining maintenance need and economics the basis for priority setting; neither systematically addresses wider sustainability issues; and, whilst cost is a major barrier to more sustainable solutions being adopted, landlords are able and have the desire to improve their practices.

Extreme weather events and business continuity planning

There is now a broad scientific consensus that the global climate is changing in ways that are likely to have a profound impact on human society and the natural environment over the coming decades. The challenge for Facilities Mangers is to ensure that business continuity plans acknowledge the potential for such events and have contingencies in place to ensure that their organisation can recover from an extreme weather event in a timely fashion. This paper will review current literature/theories pertinent to extreme weather events and business continuity planning; will consider issues of risk; identify the key drivers that need to be considered by Facilities Managers in preparing contingency/disaster recover plans; and identify gaps in knowledge (understanding and toolkits) that need to be addressed. The paper will also briefly outline a 3 year research project underway in the UK to address the issues

Investigating the use of elevators for high-rise building evacuation through computer simulation

This paper presents a description of a new agent based elevator sub-model developed as part of the buildingEXODUS software intended for both evacuation and circulation applications. A description of each component of the newly developed model is presented, including the elevator kinematics and associated pedestrian behaviour. The elevator model is then used to investigate a series of full building evacuation scenarios based on a hypothetical 50 floor building with four staircases and a population of 7,840 agents. The analysis explores the relative merits of using up to 32 elevators (arranged in four banks) and various egress strategies to evacuate the entire building population. Findings from the investigation suggest that the most efficient evacuation strategy utilises a combination of elevators and stairs to empty the building and clear the upper half of the building in minimum time. Combined stair elevator evacuation times have been shown to be as much as 50% faster than stair only evacuation times.

Property development: Appraisal and finance

The book provides an overview to the context of property development so that academics, students and professionals can examine the stages of development in the process - from initial consideration, to site finding, general appraisal, valuation, funding, construction and marketing, with a focus on two key areas of the process: appraisal and finance. The Second Edition reflects the developing research interests of the authors by putting property development and appraisal in a wider economic environment and the appraisal process was treated in a more holistic manner. Secondly, more case studies were included and the chapters framed with clear objectives key terms and summaries. Thirdly, this edition examined in more detail the property development and appraisal process in relation to sustainability and other key issues such as climate change, the changing financial environment, planning design and global influences. Research on appraisal techniques is incorporated in chapters 3-5. Research on property finance based on the original Property Lending Surveys carried out by the author and incorporated in other texts (Property Finance, 1994, 2003) is included in chapters 6-8. Research on property companies and their capital structures in included in chapter 8. Analysis of the relationship between sustainability and design is included in chapter 9. This is a key text in the area of property development, sales of the First Edition and Second Edition have been in the thousands globally to academics, students and practitioners.
