“…Related to this paper are data models that have been specifically developed for spatial design [11][12][13], for structural design [14] and to relate spatial and structural design [15][16][17][18][19][20][21][22][23][24][25][26]. The second group is generative research that yields programs, procedures, or concepts for generating (or measuring [27]) spatial and/or structural design solutions.…”

“…The research can roughly be categorized into three groups: space-allocation [1][2][3], structural optimization and grammars [4][5][6], and the support of multi-disciplinary design processes [7][8][9][10][11][12][13][14][15]. In the first two groups, it is often assumed that a strong directional activity from spatial to structural design exists (Fig.…”

“…Fenves et al [8,9] used generators that initiate the design whereas critics evaluate the current design and make redesign recommendations. Detailed and thoughtful representations (data models) for the architectural domain and the structural domain have been developed by Mora et al and Khemlani et al [10,11]. Matthews et al [12] combined their spatial design program "DesignWorkshop Professional" with the Finite Element Method.…”

“…This model defined entities to describe not only the building construction, but also enclosed spaces and the activities that these spaces contained (Eastman & Siabiris, 1995). Its main shortcoming was that the integrity constraints ensuring semantic validity were evaluated by individual applications on an as-need basis, according to their specific disciplinary requirements, rather than incorporated into the central geometric model to guarantee overall consistency (Khemlani, Timerman, Bennen, & Kalay, 1998). However, the real downfall of this enterprise approach, as discussed previously in relation to RUCAPS, was the prerequisite for a shared design process, which was at odds with the individual mode of computing introduced by the PC (Aish, 2000).…”

“…1984 saw the release of ISO Standard 10303, otherwise known as STEP (Standard for the Exchange of Product Model Data), a suite of specifications describing the generic structure and exchange of product models (Eastman, 1999;Holzer, 2007). Although STEP is not specific to the AEC industry, it established a general framework from which a number of building aspect models were developed (Bakis, et al, 2007;Khemlani, et al, 1998). These projects included:…”

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.
