1 DATA MANAGEMENT AND EXPLOITATIONS DURING THE USE OF A FACILITY (DAMEX) TKK Lighting Laboratory, Otakaari 5A, Espoo Technical Research Centre of Finland, Kaitoväylä 1, Oulu Department of Information Processing Science, Oulu University, Pentti Kaiteran katu 1, Oulu Abstract Facilities are equipped with multiple control and service systems maintained by special professional groups. During design, construction and use of the building a huge amount of data must be processed. Various intelligent tools and techniques have been created to rationalise data processing, gather and utilise data produced, and to present the data to owners, occupants, customers and users of the facility. The main idea of the project is to develop a new way to process building data, applicable for different kind of buildings. The new approach will support both networking, data transformations, and development of Knowledge Intensive Business Services. Multi-disciplinary approach is vital for upgrading facilities sector with inputs from advanced technologies. Added value will be achieved by joining the efforts of facilities management processes, data acquisition by sensors and measurements, user oriented information management, diagnostics and prognostics. The kick-off meeting of the DAMEX- project was held on May After that the project group has met several times. Due to differences in background and research areas the project group has taken time to design cooperation and finalize the working programme. Each group has successfully started its own research. The research group consists of thirteen experts, and five or six of them use most of their daily working time on the project. 1 Partners 1.1 TKK Lighting Laboratory The research group consists of subproject leader professor Jouko Pakanen, and the postgraduate students Bhusal Pramod and Jorma Lehtovaara. 1.2 Technical Research Centre of Finland, Oulu The research group consists of subproject leader Pentti Vähä, and the researchers 1

If ICT is properly applied during the whole life cycle of the building, it will upgrade the maintenance process, making the process more efficient, bringing added value to the facility, enhancing user utility and optimizing services. The main idea of the project is to develop new ways to process building data, applicable to different kind of buildings. The approach will support networking, data transformations, and development of Knowledge Intensive Business Services. This proposal focuses on the operations post occupancy phase of a facility supporting the owners, occupants and service providers with modern information technologies. The requirements of this phase will effect also on the design phase of a facility. The objective is to create and demonstrate a usable data management concept for a facility supporting different user roles. The result will contain a minimum (partially demonstrated) solution for existing building stock as well as the sophisticated concept for the new way of action. The data management over the life cycle of a facility supports the variety of users: owners, occupants, service providers, insurance companies, estate agents, fire authorities, sewerage system, waterworks, electricity works, supervision of building etc., The user centred design ensures an usable and easy to learn user interface for various users. The research will be fulfilled with six work packages: Systematics and information during the use of a facility, User centred system design, Data collection and sensor networks, Data mining and prognostics, Utility assessment and Project management and dissemination. 2

Work packages of DAMEX project Progress Report: TKK Lighting Laboratory During 2007 The Lighting Laboratory concentrated on work package 4, and especially on Tasks 4.3, 4.4 and 4.5. Pramod Bhusal has worked on Task 4.3: Lamp/luminaire component life prognostication and written a journal paper [10] on the subject. Embedded modelling (Tasks 4.4 and 4.5) has been applied in two different areas: Temperature and lighting control of building. The first one is in progress and deals with intermittent heating of a building. The demonstrated building will the METOP house of VTT, located at Otaniemi, Espoo. A thermal model of the building is already done. The next phase is to simulate the building using TRNSYS-simulation program and generate required data for the embedded model. The work has not yet been reported. The second embedded modelling concerns control of artificial lighting levels of an office room according to blind positions, set by the user and pre-calculated set-points. The objective was to create a new approach for lighting level control of office rooms, which guides the user to apply energy efficient but still satisfactory artificial lighting level, creates uniform spatial lighting level distribution in the office room by benefiting natural outdoor lighting, extends lamp life, avoids excessive instrumentation and measurements in its final implementation and benefits new IC-technology in control. The control system has been demonstrated applying the existing lighting control and data acquisition systems installed in TKK Lighting laboratory. The system is directly interfaced to the daylight measurement and photovoltaic system of the building. The lamps and Venetian blinds are controlled through Dali-bus using Digidim-Toolbox user interface. The final goal is to save the model in a serial flash memory-ic and create control system for each room with minimum measurements and instrumentation. The work has been reported in IEA Annex 45 [12,13]. 3

4 2.4 Progress Report: Technical Research Centre of Finland Achieved results Research of VTT focuses on work packages 1 (Systematics of information during the use of a facility), 3 (Data collection and sensor networks) and 5 (Utility assesment), Picture 1. Work package 1 is ready and reported earlier. A tool concept of lightweight service platform for FM services to monitor and report environment conditions in residencies developed in work package 3 has been in tests in two apartments. In 2008 we will conceive future applications for the developed platform and share this knowledge among other researchers. Final working report of the work package 5 is under construction. International activities of this project have been started with university of Berkeley during the year In the late autumn 2006 Anne Tolman (VTT) worked in UC Berkeley for approximately 1.5 months as visiting researcher, and as a result of this visit a journal article concerning the subject of WP5 of the Damex project has been published with prof. Steven Glaser from UC Berkeley. In addition, two papers have been accepted for CIB W70 Edinburgh 2008, Conference in Facilities Management, and other paper for the International Applied Science Conference Construction 2008 in Rostov, Russia has been sent. The demonstration prototype system for monitoring the level of housing circumstances in existing building stock developed in work package 3 (in close co-operation between DAMEX and FACMA - Mobile Facility Management Services projects, FACMA project is financed by VTT) has been in tests. Public presentations of the developed prototype system and enabling technologies was given in Koti- ja asumispalvelut seminar in Espoo, Finland and in Lean Construction Management Automation in Construction seminar in UC Berkeley, USA. VTT also participated by giving guidance and server provisions in a small student project, where students from Oulu University implemented some visualization of user scenarios Results exploitation International co-operation with UC Berkeley has gone further. At the moment Mr. Tommi Parkkila is as a visiting research scientist for one year at UC Berkeley continuing his research started in Damex project. The stared USENET project (Ubiquitous M2M Service Networks, ITEA project) can be mentioned as the most significant exploitations of the results of the Damex project. 2.5 Progress Report: Department of Information Processing Science, Oulu University The researcher working in the project, Niina Kantola, worked on research problem of her PhD topic: on determining usability requirements, special focus on the modeling and visualization of user scenarios. Results have been reported in conference papers. The results have also been applied in practical settings outside the Damex project (in a 4

5 healthcare sector project). Co-operation has continued with the European MAUSE project (European COST project). As a drawback, Niina Kantola finished her work in the project December PhD student Leena Arhippainen will continue Niina's work on Publications during Publications of the research groups [1] Parkkila, T.
