Abstract: At the outset of the millennium Singapore has been assertive towards a knowledge and innovation driven economy from the capital and technology intensive economy of the 1980’s and 1990’s. As a result of this new economic strategy followed by the successful implementation of science and technology plan 2010, the demand for research space has been considerably increased. This scenario has induced the development of new research campuses like biopolis, fusionopolis, CREATE and Clean Tech Park. The future prediction for research space indicates a steady demand of 100,000 sq.m per year in the forthcoming decade, as an outcome of the science and technology plan 2015.On the other hand existing research buildings are one of the major power consumers among the built environment with an average energy efficiency index of 500 Kwh/sq.m/year. Thus there arises a need to relook at the existing research buildings for a substantial reduction in the power consumption of the built environment. Hence instead of sprawling into newer research campuses this thesis investigates the possibility of vertical expansion of buildings within existing research campuses to meet the projected demand of the research space. The existing research campuses with its lower plot ratio, considerably newer buildings and higher energy consumption would be an ideal context for the process of addition and alteration in bringing down the overall energy consumption of the campus. In order to demonstrate this possibility Science Park 1 has been chosen as an appropriate development and “Building Fleming” has been selected as the suitable research building within Science Park 1 through a series of analysis and experiments for the redevelopment process towards a lower energy efficiency index. Vertical addition to the existing building along with retrofitting would be the major approach for the redevelopment process. The current working system of the research space is analysed and passive design strategies are explored to derive at an appropriate programme with respect to performance and restructuring the existing activity pattern. In addition an external passive system is introduced as a second skin in offsetting the higher magnitude of plug loads in research space. The sections arrived from the passive explorations are then stacked up in to various options with respect to the two different approaches of incremental additions and a single addition. The final scheme is derived by a fusion of these approaches along with the individual strengths of the various schemes.
