Delivering COBie data - Focus on curtain walls and building envelopes

COBie is a standard data framework whose main purpose is to transmit useful, reliable and us-able information collected throughout the whole building process and to be consumed in order to properly maintain the facility. Focusing on Facility Management information exchanges and considering the UK BIM policies and requirements, this paper shows the results obtained applying COBie to complex products such as curtain walls. Two Information Delivery Manuals (IDMs) were also developed, in order to provide a com-monly known and standardized framework, which can regulate the COBie-based information exchanges. Fu-ture developments of this study could concern the application of the developed IDMs to different case studies in order to overtake that specificity characterizing each single project and verify the validity of the proposal.
