New technologies enable innovative technical solutions and offer new potential for improvements towards support of humans nature appropriate ways of working. This demands a new culture of work and collaboration. To contribute to theses challenges is a matter the discipline 'Bauinformatik' by supporting related research, development, education and training in civil engineering. This contribution to the IKM Conference 2000 in Weimar sketches selected research and education activities of the institutes of the authors on the topics of WWW based simulation systems (example WEASEL) and of WWW based project platforms (projects MorWin and TaiGer as well as an European education experiment). Both topics supports the collaboration by new ways of tele cooperation in international, heterogeneous and interdisciplinary engineering.

The characteristics of this simulation system are as follows: (1) Web-based user interface, (2) Accessible system through the Internet and (3) Sunlight and skylight simulation based on physically accurate equations with considering various sky conditions and the reflection from the surface of objects. As a case study, impact of the development plans are analyzed and evaluated using this system. Solar irradiance, sunshine duration and sky factor are calculated at the surface of the buildings and open spaces every 10 minutes from 8 to 16 on the winter solstice. The values of these indices are expressed as the ratio to those calculated under the condition with no buildings. In conclusion, this web-based simulation system can be useful for visualizing the sunlight and skylight conditions on outdoor open spaces and the surface of the buildings to evaluate development plans objectively. Users can make access to the system from almost all of the computers connected with the Internet and modify parameters by themselves to get desirable results. Further improvement of the user interface is necessary using more advanced technology of CGI, Java and JavaScript.}, subject = {Sonnenstrahlung}, language = {en} } @inproceedings{Molkenthin2004, author = {Molkenthin, Frank}, title = {Web-based Collaborative Engineering based on Information Sharing - HydroWeb: An Education Experiment in the Internet}, doi = {10.25643/bauhaus-universitaet.186}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-1869}, year = {2004}, abstract = {This paper describes the concept and experiences of the international Open Distance Learning Course 'HydroWeb'.

In the focus of the system is to support the coordination of the participants and their information exchange. Such a software-method is well suited to ensure a high quality planning process. The modelling of business-processes enables a better self-comprehension of the participants work and helps to enhance the project performance. The system architecture of BauKom-Online contains two basic components: the processmodelling tool and the workflow-engine. The process-model contains of activities and states of the planning and construction processes and their relations. These connected processes compose the workflow. Such a process-model for engineering purposes has to satisfy several needs, e.g., the consideration of planning and building alternatives, dynamic changes of the model during execution of the project and the linkage to further technical objects like costs, building structure, specifications and documentmanagement. Furthermore, the scheduling of the project can be done within the process-model and can be visualized as a Gantt-diagram. ...}, subject = {Baubetrieb}, language = {en} }
