The demand for sustainable buildings is increasing driven in part by legislation, rising energy costs and growing environmental concerns amongst consumers. As a result clients and developers are increasingly seeking to incorporate environmental attributes into buildings and demonstrate these sustainability credentials by certifying a development using an environmental assessment methodology such as BREEAM or LEED. One of the major issues in delivering sustainable buildings is ensuring that measures incorporated into a building at design stage are translated into action during building construction. This disconnect between design and construction phases of a project often results in the need to undertake costly remedial measures to achieve a targeted sustainability rating, or the building failing the assessment. This paper suggests that by integrating BIM with Environmental Assessment Methodologies decisions made with regard to sustainability attributes at the design stage can be clearly communicated and understood by all involved in the buildings specification and construction. It introduces a conceptual framework that seeks to define the relationship between BIM and EAMs
