T1  - A SERVICE ORIENTED ARCHITECTURE FOR BUILDING PERFORMANCE MONITORING
N2  - Information technology plays a key role in the everyday operation of buildings and campuses. 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.

T1  - TRACKING OCCUPANTS AND INVENTORY ITEMS IN BUILDINGS USING RADIO FREQUENCY IDENTIFICATION (RFID) TECHNOLOGY
N2  - 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.

T1  - IMPROVING ENERGY EFFICIENT OPERATION OF BUILDINGS WITH WIRELESS IT SYSTEMS
N2  - 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.

T1  - Resource Management for the Construction Industry
N2  - 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. ...

T1  - About the implantation process of mobile computing in AEC
N2  - The AEC industry is conscious of the potentials arising from the usage of mobile computer systems to increase productivity by streamlining their business processes. Discussions are no longer on whether or not to use a mobile computer solution, but rather, on how it should be used. However, the implantation process of this new technology in Architecture, Engineering and Construction (AEC) and Facility Management (FM) practise is very slow and should be improved. One way to encourage and ease the usage of mobile computer systems in AEC is a more process-oriented usability and context appropriateness of mobile computer solutions. Context-sensitivity is defined as a crucial feature to be taken into account for further research in the area of Mobile Computing. Context-sensitive, mobile IT-solutions depend on two features: (1) flexible definitions of (construction) processes describing the context and (2) tools for flexible, multi-dimensional information management representing the context. It is on this premise that the authors propose the n-dimensional data management approach for the implementation of mobile computing solutions. In this paper, we analyse working scenarios in the AEC and FM sector, defining context aspects which are transformed and formalized as dimension hierarchies of the envisaged context model.

T1  - Processing "fuzzy" materials sets for environmental impact analysis of buildings
N2  - Processing technical and environmental data on building materials, components, and systems has become more important during the last few years. Increased sensitivity towards environmental and energy problems has lead to the demand for simulation and evaluation of the long term behavior of buildings. The results of such simulations are expected to enable architects and engineers to develop a broader, interdisciplinary understanding of the impact of their products (buildings) on the environment. However, conducting such evaluations is currently hampered by the lack of comprehensive, up-to-date, and ecologically relevant data on building materials, components, and systems. To address this problem, this paper proposes an approach to deal with the absent or uncertain attributes of building materials, components, and systems. In the past, various information systems have been developed to provide data on a limited set of building materials, including precise values pertaining to some of their characteristics, such as availability, manufacturers, costs, etc. These traditional information systems have difficulty in dealing with uncertain, incomplete and sparse data. However, uncertainty and incompleteness characterize the nature of most of the available and environmentally related characteristics of materials, components, and systems. In this paper, a fuzzy-logic-based augmentation of traditional information systems is proposed towards providing management, utilization and manipulation of incomplete and uncertain data.

T1  - Reorganisationspotentiale im Bauwesen durch Nutzung mobiler Informations- & Kommunikationstechnologien
N2  - Die Verfügbarkeit und die sichere Beherrschung moderner und kostengünstiger Informations- und Kommunikationstechnologien gestattet es auch kleinen unternehmerischen Einheiten im Bauwesen sich in betriebsübergreifenden Netzwerken zu organisieren und sich besser in die Wertschöpfungskette am Bau zu integrieren. In sogenannten >Virtuellen Organisationen< (VO) können diese für die Volkswirtschaft wichtigen Unternehmen ihre Wettbewerbsvorteile wie höhere Flexibilität, schnelle Reaktion auf Kundenwünsche und Marktnähe nutzen und somit ihr langfristiges Bestehen in einem liberalen Wettbewerb auf einem erweiterten EU-Markt sichern und ausbauen. Die derzeit existierenden Hindernisse im Informationsfluss zwischen Baustelle und Büro können durch den Einsatz mobiler, funkvernetzter Endgeräte, wie beispielsweise >Smart-Phones<, und einer neu zu gestaltenden Infrastruktur zum Wissensmanagement und zur kontextsensitiven Informationsdarstellung abgebaut werden. Im Rahmen dieser Veröffentlichung werden konzeptionelle Ansätze eines integrierten Informationsmanagements zur Unterstützung von VO, die im Rahmen des BMBF-Projektes >IuK-System Bau< derzeit entwickelt werden, vorgestellt.

T1  - "Mobile Computing" - Anforderungen & Einführungsstratgie aus Sicht der Baupraxis
N2  - Die Sicherung der Wettbewerbsfähigkeit im Bereich des Bauwesens, insbesondere kleinerer und mittelständischer Betriebe erfordert ein aktives Handeln als Antwort auf die sich ändernde Wettbewerbssituation. Einen wesentlichen Wettbewerbsvorteil können kleine unternehmerische Einheiten durch höhere Flexibilität, schnelle Reaktion auf Kundenwünsche oder aktuelle Situationen auf der Baustelle und Marktnähe erreichen. Dazu ist es nötig, die Informations- und Kommunikationsströme durch Einsatz standardisierter und kostengünstiger Hard- und Software wie z.B. Handhelds zu unterstützen und insbesondere die existierenden Hindernisse im Informationsfluss zwischen Baustelle und Büro zu beseitigen. Am Beispiel der Projekte >IuK - SystemBau< und >eSharing< wird eine Einführungsstrategie für >Mobile Computing< in kleinen unternehmerischen Einheiten des Bauwesens (KMU) basierend auf einer umfangreichen Anforderungsanalyse vorgestellt. Folgende Aspekte sollen beschrieben werden: durchgängiger Einsatz der Technik unter Beachtung der verschiedenen Qualifikationsniveaus, Einführungsunterstützung durch Schulungen, Prozessanalyse und mögliche Integration in bestehende Software-Umgebungen sowie Feldtests.

T1  - Information technology for construction management and building performance evaluation support -  a North-American perspective
N2  - We provide a critical overview of the current status of computational support for construction the management and building performance evaluation in North-America. 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.
