The architects and builders in the past lacked our knowledge concerning fluid dynamics, but they exhibited a deep rooted ability to observe and reflect - thus, different cultures have developed by trial and error. The authors have produced a stimulating analysis which couples the science of fluid dynamics and a sensitive understanding of past cultures. The paper is recommended reading. 相似文献

During the winter of 1988/1989, the relationships between the prevalence of work-related health and indoor climate complaints and a number of building, management, workplace and personal characteristics have been investigated in a study in more than 60 office buildings located throughout the Netherlands. To collect the information, a questionnaire was prepared on health and indoor climate complaints and personal and workplace characteristics. A checklist was used to obtain information on building characteristics More than 7000 questionnaires were completed by the regular users of the buildings investigated. The results showed that the prevalence of symptoms was higher in air-conditioned buildings than in naturally or mechanically ventilated buildings. some other variables were also related with most work-related complaints after adjustment for selected management, personal, workplace and job characteristics. These included gender, work satisfaction in general, presence of allergies and/or respiratory symptoms, and personal control over temperature at the workplace. No differences were found in symptom prevalences between buildings with spray and steam humidification. The combination of air-conditioning and humidification did not lead to further increases in the prevalence of complaints as compared to buildings with only airconditioning or only humidification. 相似文献

Eric Gabriel 《International Journal of Project Management》1985,3(4):231-232
The role of the project manager has traditionally concentrated upon the execution of a project, from conception to completion. The commissioning and operation have been a secondary priority, for good reasons which are discussed in this paper. Nowhere has this been more true than in building construction, despite the fact that a building is a place where there is maximum interaction with people of all types. Some 10% of people worldwide are disabled, which prevents them from using buildings and facilities designed for able-bodied people. All this is changing rapidly. No longer should buildings be designed to be accessible only to the majority, nor should special arrangements be provided as an ‘extra’ for disabled people. Design philosophy is being impelled to provide for all building users. Great impetus was provided by the 1981 International Year of Disabled Persons, designated by the United Nations. In the UK, The Prince of Wales' Advisory Group on Disability and the Access Committee for England are influential and active organizations that are exerting a powerful influence for change. New building regulations are introducing a statutory imperative. The attention of project managers is drawn to what is happening in this area, and it is suggested that in their unique position they can influence the bridging of the gap between designers and building operators, to ensure that buildings can be used by all, and that nothing is overlooked at any stage. Legislation alone cannot solve the problem, and a change in attitude is necessary. 相似文献

Photovoltaic (PV) cells, when integrated within a building facade, offer the possibility of generating electric power and heat for local use or export. This paper reports on a project to investigate the practical operational efficiencies that might be delivered from such facades. The results from laboratory experiments and computer simulations are presented: the former were used to develop an empirical relationship between cell temperature and power output; the latter were undertaken to assess operational efficiencies under a range of climate conditions representative of the UK. 相似文献
