Many proprietary technologies and methodologies can assist in effective Building Performance Monitoring (BPM) and efficient managing of building resources. The integration of related tools like energy simulator packages, facility, energy and building management systems, and enterprise resource planning systems is of benefit to BPM. However, the complexity to integrating such domain specific systems prevents their common usage. Service Oriented Architecture (SOA) has been deployed successfully in many large multinational companies to create integrated and flexible software systems, but so far this methodology has not been applied broadly to the field of BPM. This paper envisions that SOA provides an effective integration framework for BPM. Service oriented architecture for the ITOBO framework for sustainable and optimised building operation is proposed and an implementation for a building performance monitoring system is introduced.}, subject = {Angewandte Informatik}, language = {en} } @inproceedings{KhanCongKarstenetal., author = {Khan, Farhan Manzoor Ahmed and Cong, ZiXiang and Karsten, Menzel and Stack, Paul}, title = {TRACKING OCCUPANTS AND INVENTORY ITEMS IN BUILDINGS USING RADIO FREQUENCY IDENTIFICATION (RFID) TECHNOLOGY}, editor = {G{\"u}rlebeck, Klaus and K{\"o}nke, Carsten}, organization = {Bauhaus-Universit{\"a}t Weimar}, issn = {1611-4086}, doi = {10.25643/bauhaus-universitaet.2856}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20170314-28562}, pages = {13}, abstract = {In order to make control decisions, Smart Buildings need to collect data from multiple sources and bring it to a central location, such as the Building Management System (BMS). This needs to be done in a timely and automated fashion. Besides data being gathered from different energy using elements, information of occupant behaviour is also important for a building's requirement analysis. In this paper, the parameter of Occupant Density was considered to help find behaviour of occupants towards a building space. Through this parameter, support for building energy consumption and requirements based on occupant need and demands was provided. The demonstrator presented provides information on the number of people present in a particular building space at any time, giving the space density. Such collections of density data made over a certain period of time represents occupant behaviour towards the building space, giving its usage patterns. Similarly, inventory items were tracked and monitored for moving out or being brought into a particular read zone. For both, people and inventory items, this was achieved using small, low-cost, passive Ultra-High Frequency (UHF) Radio Frequency Identification (RFID) tags. Occupants were given the tags in a form factor of a credit card to be possessed at all times. A central database was built where occupant and inventory information for a particular building space was maintained for monitoring and providing a central data access.}, subject = {Angewandte Informatik}, language = {en} } @inproceedings{GokceBrowneGokceetal., author = {Gokce, Hasan Ufuk and Browne, Donal and Gokce, Kamil Umut and Menzel, Karsten}, title = {IMPROVING ENERGY EFFICIENT OPERATION OF BUILDINGS WITH WIRELESS IT SYSTEMS}, editor = {G{\"u}rlebeck, Klaus and K{\"o}nke, Carsten}, organization = {Bauhaus-Universit{\"a}t Weimar}, issn = {1611-4086}, doi = {10.25643/bauhaus-universitaet.2845}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20170314-28453}, pages = {19}, abstract = {Reducing energy consumption is one of the major challenges for present day and will continue for future generations. The emerging EU directives relating to energy (EU EPBD and the EU Directive on Emissions Trading) now place demands on building owners to rate the energy performance of their buildings for efficient energy management. Moreover European Legislation (Directive 2006/32/EC) requires Facility Managers to reduce building energy consumption and operational costs. Currently sophisticated building services systems are available integrating off-the-shelf building management components. However this ad-hoc combination presents many difficulties to building owners in the management and upgrade of these systems. This paper addresses the need for integration concepts, holistic monitoring and analysis methodologies, life-cycle oriented decision support and sophisticated control strategies through the seamless integration of people, ICT-devices and computational resources via introducing the newly developed integrated system architecture. The first concept was applied to a residential building and the results were elaborated to improve current building conditions.}, subject = {Angewandte Informatik}, language = {en} } @inproceedings{KellerAntoniadisMenzel2004, author = {Keller, Martin and Antoniadis, George and Menzel, Karsten}, title = {Resource Management for the Construction Industry}, doi = {10.25643/bauhaus-universitaet.167}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-1679}, year = {2004}, abstract = {The management of resources is an essential task in each construction company. Today, ERP systems and e-Business systems are available to assist construction companies to efficiently organise the allocation of their personnel and equipment within the company, but they cannot provide the company with the idle resources for every single task that has to be performed during a construction project. Therefore, companies should have an alternative solution to better exploit expensive resources and compensate their fixed costs, but also have them available at the right time for their own business activities. This paper outlines the approach taken by the EU funded project "e-Sharing" (IST-2001-33325) to support resource management between construction companies. It will describe requirements for the management of construction resources, its core features, and the integration approach. Therefore, we will outline the approach of an integrated resource type model supporting the management and classification of construction equipment, construction tasks and qualification profiles. The development is based on a cross-domain analysis and evaluation of existing models. ...}, subject = {Baubetrieb}, language = {en} } @inproceedings{BerbigMenzelEisenblaetter2003, author = {Berbig, Torsten and Menzel, Karsten and Eisenbl{\"a}tter, Karin}, title = {"Mobile Computing" - Anforderungen \& Einf{\"u}hrungsstratgie aus Sicht der Baupraxis}, doi = {10.25643/bauhaus-universitaet.294}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-2948}, year = {2003}, abstract = {Die Sicherung der Wettbewerbsf{\"a}higkeit im Bereich des Bauwesens, insbesondere kleinerer und mittelst{\"a}ndischer Betriebe erfordert ein aktives Handeln als Antwort auf die sich {\"a}ndernde Wettbewerbssituation.

This overview is based on the research conducted in relation to the design and construction of the Intelligent Workplace (IW), Carnegie Mellon University, Pittsburgh, Pennsylvania, USA. With regard to the commercial software products in the field of construction management the following limitations can be identified: Although project planning, cost estimating and construction simulation are supported, tasks like bidding as well as site and material management have not received the same level of attention. Few project management software packages are integrated in a total design support software system. Little analysis or evaluation options are provided to support managerial decision making. Various research groups address the construction planning and scheduling, construction contracting, site layout generation as well as the integration of these three topics. Currently problems such as efficient material management and calculation of environmental and energy responsive site management are insufficiently addressed within the ongoing research projects. In the domain of building performance simulation and decision support one can notice that, the development and application of computational tools is industry driven. As a result the concerns addressed by the tools are mainly issues pertaining to the selection and sizing of systems and components rather than an integrated performance evaluation. Consequently, these programs are rarely used by building designers, especially in the early design stages, where the predictive capabilities of simulation tools could be of significant value. Although many research institutions address the necessity for the integration of performance simulation within the overall design support environments most of the practically available performance simulation tools still remain mono-dimensional and isolated.}, subject = {Bauausf{\"u}hrung}, language = {en} }
