Insulation the Saudi way

Attention focuses on the growing building market in Saudi Arabia. This article from the Materials Testing Laboratory in Riyadh on some local building techniques explains the theoretical approach which seems to favour the use of suspended gypsum plasterboard for thermal insulation in the prevailing climatic conditions.     

Taming systems the Czechoslovak way

High productivity and concentrated development are still seen as priorities in Czechoslovak housing so that large-panel building systems are still favoured. But their adaptability to design needs has been a preoccupation of research, resulting in one system that offers over 200 different panel types. The author is a research worker at the Slovak Research and Development Centre for Planning and Architecture in Bratislava.     

Changing the way we do business

In order for innovations to occur in any sector, new ideas must both be developed and deployed. Major barriers to ideological change often stem from individual or organizational paradigms—an inability to imagine unfamiliar ways of doing business.Major innovations and paradigm shifts took place at the turn of the century, in response to a rash of fires that destroyed a host of major American cities. Since then, new discoveries have emerged from the research community, but many have not been deployed into day-to-day practice.The author urges another major paradigm shift—to imagine how fire safety design could differ dramatically from today's familiar practice; and to search for strategies to effect innovation in the 21 st Century.Prepared for presentation at the Conference on Firesafety Design in the 21st Century, Worcester, Massachusetts, May 8, 1991     

法中求法:访崔恺

我在学生时代就对浪漫的法国文化怀有一种天真的仰慕。但我第一次去法国．还是在1995年。1994年．法国建筑师在清华大学搞了一次建筑展。作为回访．中国建筑学会1995年组织国内八家设计院去法国办建筑展．我是代表团成员之一。到了巴黎．感觉到非常的震撼．旧城与新城的关系，新的文化建筑与历史环境的关系．都体现出巴黎城市的魅力。     

Planning and the rule of law

The impact of law in shaping the way in which spatial planning is conducted is often overlooked and attitudes to law are often purely instrumental. This paper looks at how the concept of the rule of law has evolved in England, and what effect it has had on public administration and on spatial planning processes in particular. It looks particularly at the role of equity within the common-law tradition and the way in which equitable judgment has coloured administrative decision-making. It concludes that by comparison with legal processes decision-making in spatial planning is often insufficiently rigorous.
