In the Pursuit of Pleasure: The Not so Fleeting Life of the Pavilion and its Ilk

Author and architecture critic for the London Evening Standard, Robert Bevan reflects on the enduring appeal of the temporary structure, speaking ‘to a latent desire for freedom and movement’ as a hangover of our nomadic past in a sedentary ‘civilised’ society. He highlights the type's historical apex in Henry VIII's palatial pop-up on the Field of the Cloth of Gold, questioning the purpose and purposelessness of more recent examples.     

Contextual Counterpoint

In recent decades, conservationists and planners have co-opted contextualism, reducing it to a tool for enforcing urban conformity. Here Charles Jencks reclaims contextualism as a dynamic design strategy. He identifies four different contextual treatments that as well as ensuring continuity are potentially transformative.

The Employment of Reason

Rationalism in the Netherlands is characterised by pragmatism. As Charles Rattray explains it is a practical bent that was driven in the 20th century by the exigencies of building cheaply and quickly a large amount of social housing on a relatively small amount of land. It is a strand that has been underscored by a belief in reason across time and a confidence in an analytical approach. Copyright © 2007 John Wiley & Sons, Ltd.

A comparative analysis of three of ERDA''s major R & D programs

The benefits attributable to alternative energy R & D programs should be evaluated in terms of how well the technologies contribute as integral elements of the total United States energy system (rather than as isolated entities, as has typically been done in the past). Thus, the present model simulates the dynamics of the evolution of the total energy system by requiring both existing and new technologies to compete for introduction (i.e. commercialization) on a cost-competitive basis that considers the time phasing of

1. (1) retirement of energy conversion facilities,

2. (2) growth in end-use demands, and

3. (3) escalation of the costs of extracting depleting domestic energy resources.

This approach contrasts with a static model used by the Energy Research and Development Administration (ERDA), wherein assumptions must be made for each future year of interest for

1. (1) maximum capacity constraints for alternative types of conversion facilities and

2. (2) the cost of energy resources.

The present model is used to compare the relative consequences and merits of the technology products from the following three of ERDA's major energy R & D programs:

1. (1) the liquid-metal fast breeder reactor (LMFBR),

2. (2) synthetic fuels derived from coal and oil shale, and

3. (3) improved efficiencies for end-use devices (e.g. space heaters).

It is found that the development of synthetic fuels derived from coal and oil shale is the only alternative (of the three considered) that provides energy independence for the United States in the next fifty years. However, the possible collapse of the world oil cartel is shown to pose a major retardant to synfuels commercialization by the private sector until at least the end of the century. The substantial environmental impact from synfuels commercialization could be reduced significantly with the accelerated introduction of end-use utilizing devices with improved efficiencies. This latter program could result in a significant reduction in the costs of operating the United States energy ststem over the 60-yr period considered by the model. The discounted present value of this “cost reduction” (i.e. the “economic benefit”) would be two orders of magnitude greater than the R & D investment, at least one order of magnitude greater than the expected economic benefits from synfuels commercialization and two orders of magnitude greater than the economic benefits from the commercialization of the LMFBR. However, the lack of performance and cost studies of improved efficiency in end-use suggests increased funding for these technologies rather than reduced funding for the breeder.     

Gert Wingårdh

From his main office in Gothenburg, Sweden's second city, Gert Wingårdh has spawned a practice that has brought him national success. He has completed two embassy buildings for the Swedish foreign office in Washington DC and Berlin and two major museums. Timothy Tore Hebb describes the work of an architect whose designs are able to be both responsive to the natural environment and ingenious in their juxtapositions and contrasts.
