title	Aspects of S2

summary	We present in this paper the essential aspects of the S2 system. This is the internet realization of SEMPER, an active, multi-domain, space-based, object oriented design environment for integrated building performance modeling. The key features of the S2 environment are as follows: A user can access the system regardless of the computer hardware, operating system or the location on a network; geographically distributed users can asynchronously generate a building model through the user interface; this building model can then be simultaneously evaluated with multiple simulation applications running on remote simulation servers; persistent storage is provided for project data and evaluation results; designers using the system have access to multiple libraries that contain building information such as material data, construction types, schedules, and weather data.

title	A Performance-inspired Building Representation for Computational Design
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 117-132
summary	A building representation for integrated building performance simulation is described, which addresses several important issues. First, it captures informational requirements for detailed performance analysis and maintains geometric integrity. Second, it provides computational support for efficient spatial queries and convenient building model manipulation. Representational elements include partitioning and refinement rules, containment hierarchies and dimension constraints. These features provide for ease of manipulation, geometric variety and spatial queries and are illustrated with examples. The paper concludes with a discussion of the limitations of the representation.

title	Environmental Life Cycle Assessment in an Integrated CAD Environment: The Ecologue Approach
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 351-363
summary	Construction and operation of buildings is a major cause of resource depletion and environmental pollution. Computational performance evaluation tools could support the decision making process in environmentally responsive building design and play an important role in environmental impact assessment, especially when a life cycle assessment (LCA) approach is used. The building domain, however, presents notable challenges to the application of LCA methods. For comprehensive environmental impact analysis to be realized in a computational support tool for the building design domain, such tools must a) have an analysis method that considers the life cycle of building construction, operation, and decommissioning, b) have a representation that is able to accommodate the data and computability requirements of the analysis method and the analysis tool, and c) be seamlessly integrated within a multi-aspect design analysis environment that can provide data on environmentally relevant building operation criteria. This paper reviews the current state of assessment methods and computational support tools for LCA, and their application to building design. Then, the implementation of an application (ECOLOGUE) for comprehensive computational assessment of environmental impact indicators over the building life cycle is presented. The application is a component in a multi-aspect space-based CAD and evaluation environment (SEMPER). The paper describes the use and typical results of ECOLOGUE system via illustrative examples.

title	A comprehensive computational environment for performance based reasoning in building design and evaluation
source	Automation in Construction 8 (4) (1999) pp. 427-435
summary	This paper introduces a comprehensive computational implementation effort toward the incorporation of simulation-based performance evaluation in building design. Specifically, the computational design support system `SEMPER' will be described. SEMPER's main objectives are: (i) a methodologically consistent (first-principles-based) and flexible performance modeling approach through the entire building design and engineering process; (ii) provision of comprehensive, i.e., multi-domain building performance evaluation support; (iii) seamless and dynamic communication between the simulation model and the general building representation in an object-oriented space-based design environment; and (iv) active convergence support via a bi-directional inference mechanism that provides not only the conventional design-to-performance mapping option but also a `preference-based' performance-to-design mapping technology.
