Abstract. The increasing complexity of the built environment requires that more knowledge and experience be brought to bear on its design, construction and maintenance. The commensurate growth of knowledge in the participating disciplines-architecture, engineering, construction management, facilities management, and others-has tended to diversify each one into many sub-specializations. The resulting fragmentation of the designbuilt-use process is potentially detrimental to the overall quality of built environment. An efficient system of collaboration between all the specialist participants is needed to offset the effects of fragmentation. It is here that computers, with their ubiquitous presence in all disciplines, can serve as a medium of communication and form the basis of a collaborative, multi-disciplinary design environment. This paper describes the ongoing research on the development of such an integrated computing environment that will provide the basis for design and evaluation tools ranging across the many building-related disciplines. The bulk of the discussion will focus on the problem of a building representation that can be shared by all these disciplines, which, we posit, lies at the core of such an environment. We discuss the criteria that characterize this shared building representation, and present our solution to the problem. The proposed model has been adapted from geometric modeling, and addresses explicitly the difficult problem of generality versus completeness of the represented information. The other components of the integrated environment that are under development are also described. The paper concludes with some implementation details and a brief look at two evaluation tools that use the proposed building representation for their task.

“…Modularisation has similarly long been advocated as a strategy for computer systems to support the collaborative modelling of buildings (Cerulli, 2006;Coenders, 2007;Eastman, 1992;Flager, Welle, Bansal, Soremekun, & Haymaker, 2009;Galle, 1995;Holzer, Tengono, & Downing, 2007;Mahdavi, 2009;Maver, 1971;Papamichael, LaPorta, & Chauvet, 1997;Pohl & Myers, 1994). The rationale behind this, as Pohl & Myers (quoted in: Galle, 1995, p.197) state, is that:…”

“…This requires data sharing via federated databases that maintain semantic integrity across multiple domainspecific representations to provide a single unified view of the building model (Aish, 2000;Bakis, et al, 2007;Cerulli, 2006;Galle, 1995;Halfawy, 2010;Vanlande, et al, 2008). As Vanlande et al (2008, p.72) explain, in this scenario "applications allow the use of different formats and keep the consistency of data throughout the entire building lifecycle ... [such that] project information can be stored in a variety of ways to feed many different workflows or setups that do not fit a preset standard".…”

Energy simulation for decision support in early architectural design

Decisions made in the earliest stage of architectural design have the greatest impacts on the environmental and financial performance of buildings. Yet despite being one of the largest contributors to energy consumption and cost, building services are rarely a driving influence in the conceptualisation of architectural form.If building professionals are to engage in sustainable design practices, they must be able to assess the performance impacts of different design options prior to major architectural characteristics becoming fixed. Current modelling and simulation tools, however, largely lack the capacity to resolve design and performance constraints simultaneously. New digital tools and processes for exploring the interdependencies between architecture, building services and energy consumption in early design are needed, so that individual professionals can understand the impacts of their decisions on those of other disciplines and on building performance.In response to this problem, this thesis proposes a framework for performance-oriented design that supports integrated decision-making by enabling architects and engineers to work together to simulate and evaluate the energy performance of design alternatives early on. Arguing the need to work across disciplinary boundaries, it demonstrates how cross-cutting performance objectives can better structure and streamline the integration between design and analysis tasks by establishing a shared basis for communication. Guided by an embedded-practice research methodology, this thesis draws on firsthand experience of multidisciplinary practice to identify the limitations of current tools and processes in supporting performance-oriented investigations, and establishes common goals and principles for an integrated energy-oriented design strategy. It then describes a collaborative tool for energy design and analysis that has been developed as a critical response to observed shortcomings, which provides decision support by permitting practitioners to quickly, flexibly and reliably assess the performance of multiple design options early on.Central to this research is the understanding that there is a need to unify the disparate methods of working that have been adopted by architects and engineers as a result of progressive specialisation within the building industry. This understanding suggests that there is more to the design process than simply data exchanges supported by a common building representation, and points to the importance of communication networks that strengthen the dialogue between architect and engineer. In responding to this finding, the proposed framework facilitates the sharing of knowledge across disciplines, which is of as great a benefit to the design process as the performance evaluation capabilities that it also provides.
