Distributed web-based building performance computing: a Singapore-US collaborative effort

This paper reports on the progress of the S2 project. This is an ongoing effort toward an Internet-based environment for distributed collaborative performance-based building design and evaluation. A user can access the S2 system regardless of hardware, operating system or location on a network. Geographically distributed users can generate and edit building models via a platform-independent user interface. These building models can then be made subject to concurrent analysis by multiple simulation applications running on remote servers. Persistent storage is provided for project data and evaluation results. Designers using the system have access to multiple libraries with semantic building information.
