The CASL-streamlined management structure includes collocation at CASL, use of technology to achieve multidiscipline collaboration, video conferencing for meetings, and a VOCC project that integrates both the latest and emerging technologies to build an extended ``virtual one roof.'' CASL is headquartered at ORNL, where the CASL leadership and a majority of the multidisciplinary, multi-institutional scientists and engineers will be located. Work performed at partner sites will be seamlessly integrated across the consortium on a real-time basis via community and computing (VOCC) capability that integrates both the latest and emerging technologies to build an extended ``virtual one-roof'' allowing multidisciplinary collaboration among CASL staff at all sites. The paper describes the VOCC collaboration system. \itemrv{~} \itemcc{} \itemut{User Centered Systems Design; Collaboration; Collaborative Virtual Environments; Collaborative Computing; Human Computer Interaction; Energy Science Hub} \itemli{doi:10.1007/978-3-642-21753-1\_48} \end
