This research paper set out to explore the following research question: "what shape and form should a building be in order to achieve energy efficiency in the design and construction of the tall office building?" This involved the exploratory case study of a spheroid building, the Greater London Authority (GLA) building, as well as the Prolate-Oblate Spheroid Concept. The Greater London Authority building was acclaimed as being energy efficient, with claims of 75% reduction in its annual energy consumption compared to a high specification office building. This claim was explored to better understand the nature of the spheroid form in construction. The Greater London Authority building appeared to have achieved a high level of energy efficiency but a number of problems were reported. However, it was not clear how many of these problems were associated with its morphology. The 3D to nD research project is aimed at developing a multi-dimensional computer modelling tool that simulates the entire design and construction process with reference to specific parameters, such as energy efficiency, in order to improve the decision-making process and construction performance. This research paper explored the 3D to nD modelling methodology through comparative study of the energy efficiency assessment of the Greater London Authority building. Keywords – 3D to nD, Greater London Authority building, Spheroidal

"The Role of Environmental Design in Tsunami Impact Management"
by
Emeka Efe Osaji
30/09/2005Abstract:
This research aims to acquire in detail, data on the extent of damage caused by the 2004 Asian tsunami to the ecosystems, environmental infrastructure, human population and built environment, in order to propose suitable designs for the protection of the affected ecosystems from future risks and the protection of potential at-risk ecosystems. This will contribute to the sound management of its natural, built and human resources by the derivation of the following:
- A comprehensive environmental database of affected areas of Southeast Asia, which will assist in effective planning and design against future tsunamis
- A detailed Southeast Asia Threat-Level Map, which will graphically rate and categorise Southeast Asia tsunami prone areas according to the magnitude of risk
- A detailed Global Threat-Level Map, which will graphically rate and categorise global tsunami prone areas according to the magnitude of risk
- Interesting concepts for the design of tsunami resistant architectural and environmental structures
- A set of appropriate guidelines for the establishment, as well as enforcement of strict building codes and designs along Southeast Asia and global coastal areas.
Current knowledge in this area can be found in the United Nations Environment Program (UNEP) 2005 Report entitled, 'After the Tsunami – Rapid Environmental Assessment.'

E.E.Osaji@salford.ac.uk; G.Aouad@salford.ac.uk; N.Bakis@salford.ac.uk Abstract:
This paper explores the role of the effective use of information technology, through the 3D to nD Modelling project, amongst others, in improving the efficiency and effectiveness of the integrated design and construction process. It also reviews the issues involved in the evaluation of the business benefits of information systems. The 3D to nD research project, at the University of Salford, aims to develop a multi-dimensional computer modelling tool that simulates the entire design and construction process with reference to specific parameters in order to improve the decision-making process and construction performance. This paper focuses on the opportunities offered by the utilisation of this 3D to nD Modelling, as well as Information Systems Development, Information Visualisation, Artificial Intelligence Agents, Simulation, Advanced Robotics and Intelligent Machines, in revaluing and improving the integrated design and construction process. Keywords – 3D to nD Modelling, Artificial Intelligence Agents, Databases, Intelligent Machines, Robotics, Simulation, Visualisation
