summary:The main aim of the research presented in this paper is to contribute to a reduction in carbon emissions from buildings. Carbon reduction is a global goal and in line with this UK government policy seeks to reduce carbon emissions 60% by 2050, and 80% by 2100, compared to 1990 levels. To meet these targets it will be necessary to greatly improve the energy performance of the built environment. Current green building guidelines and frameworks provide information about which design standards should be achieved but they lack practical information about how to meet those standards. One of the main objectives of this research is to ameliorate this problem. To do so a process framework for building design and an ICT system to support multi stakeholder decision making that facilitates the inclusion of energy issues in the early design phase of buildings has been developed. The framework developed is an extension of the Royal Institute of British Architect (RIBA) plan of work stages, and as such can be described as a RIBA sub-process. The ICT system ‘dubbed’ Environmental Assessment trade-off tool (EATT) is designed to support multi stakeholder decision making in the design process. The main aims of this paper are to identify gaps in the RIBA process and current green construction guidelines with regard to supporting the design of new energy efficient buildings and building refurbishments, outline the RIBA sub-process and the EATT and demonstrate the application of the trade off tool in a case study.
