Research, knowledge and design

The discussion about relations between research and design has a number of strands, and presumably motivations. Putting aside the question whether or not design or “creative endeavour” should be counted as research, for reasons to do with institutional recognition or reward, the question remains how, if at all, is design research? This question is unlikely to have attracted much interest but for matters external to Architecture within the modern university. But Architecture as a discipline now needs to understand research much better than in the past when ‘research’ was whatever went on in building science, history or people/environment studies. In this paper, I begin with some common assumptions about design, considered in relation to research, and suggest how the former can constitute or be a mode of the latter. Central to this consideration is an understanding of research as the production of publicly available knowledge. The method is that of conceptual analysis which is much more fruitful than is usually appreciated. This work is part of a larger project in philosophy of design, in roughly the analytical tradition.

Erluanbi, Southern Taiwan

Erluanbi is the most southern tip of Taiwan (Formosa) where the Taiwan (Formosa) Strait meets the Pacific Ocean. The Erluanbi national park is renown for its lighthouse, and its coral reef, and it hosts also some prehistoric sites bating back to 5,000 to 6,500 years. The Erluanbi (or Eluan Pi) lighthouse was completed in 1883, following requests from the American and Japanese governments to the Chinese government after several ship wrecks in the 1860s. Chinese troops were sent to protect the lighthouse construction from attacks by local tribesmen, and the lighthouse was surrounded a small fort with cannons and a ditch to protect it. It is a rare example of a fortified lighthouse in the world. The lighthouse itself is 21.4 m high and its light is 56.4 m above high water. The light flashes every 10 seconds and its range is 27.2 nautical miles. The surrounding Erluanbi national park is located on a raised coral reef with some huge fringing reef : e.g., the "sea pavillon". With the topical oceanic climate, the elevated reef hosts an unique vegetation and ecology. Since 1956, numerous prehistoric artefacts were uncovered including stone slab coffins and pottery (plain and painted), that encompassed at least four cultural stages from BC 4,500 to AD 800.

Dual mode cooling house in the warm humid tropics

Passive techniques as an alternative to artificial cooling can bring important energy, environmental, financial, operational and qualitative benefits. However, regions such as the wet tropics can reach high levels of thermal stress in which passive means alone are unable to provide appropriate thermal comfort standards for some parts of the year. Despite a great accumulation of empirical information on the passive performance of houses for either free-running or conditioned modes, very little work has been done on the thermal performance of buildings that can operate with a mixed-running strategy in warm-humid climates. Buildings with such design features are able to balance the needs for comfort, privacy, and energy efficiency during different periods of the year. As free-running and conditioned modes are believed by many to be 'opposite' approaches, and have been presented as separate strategies, this paper demonstrates that not all parameters are directly opposite and a possible dual-mode integrated operation can be used for warm-humid locations for maximum comfort and minimum energy requirements. For this purpose, simulation runs using ESP-R (University of Strathclyde, ESRU, UK) were based on the climate data of Darwin (Australia) and on the ventilation styles of the house: free running and conditioned. Design features applicable to both, i.e. for a dual mode operation could be identified and the differences between conditioned and free running were demonstrated and proved not to be totally conflicting and therefore suitable for a dual mode operation. Different daily usage profiles (five use patterns were defined), and zoning of sleeping and living areas are presented. The dual mode use patterns compared to the base case house, for all the user possibilities, had improved performances of 17-52%, when compared to the free-running mode and 66-98% when compared to the conditioned mode. Simulation runs using other warm-humid climates (Miami, USA; Sao Luis, Brazil; Kuala Lumpur, Malaysia) were also conducted and compared to the results found for Darwin. (C) 2002 Elsevier Science Ltd.
