Information and Communication Technology for Intelligent and Integrated Controls in Buildings: Current Developments and Future Research

Abstract: A common and acknowledged vision today is the one that, in the future, buildings, along with their components, equipments, and their environment will communicate and be able to provide information on their status ubiquitously. This real-time available information will be interoperable via common protocols for holistic automation & control. The whole building will be supervised by intelligent systems, able to combine information from all connected devices, from the Internet or from energy service providers in order to efficiently control HVAC (heating & cooling), lighting, and hot water systems along with energy production, storage and consumption devices inside the building, taking into account the users' needs and wishes. In such a context, ICT is recognised as key for empowering people in the (built) universe in which they live, with smart e-metering and new smart e-devices – as well as becoming fully pervasive in the future optimization of energy in the built environment - where “Energy-efficient smart buildings” are to be buildings which contain systems that manage information for an optimal operation of building energy flows over the whole building lifecycle.In such a context, CSTB has developed an open framework for data collection and processing, to be installed in any built environment. It supports networked heterogeneous sensors and actuators (with appropriate communication protocols technology), allows assembling various “business” functions (with easy evolution and extension capability thanks to a concept of service composition and event-driven management between modules), can accommodate any hardware platform constraint (memory, computing power), and can be executed in any environments supporting a Java SE implementation. The framework is itself based on an OSGi platform. The notion of “sensor” is to be considered in a comprehensive way: physical sensor (analogic or logic), complex sub-system or meta-sensor (e.g. Agilent data acquisition system or alike), or even external services (e.g. getting weather data via the Internet). Fields of applications are energy-efficiency in the built environment, but also Ambient-Assisted Living (AAL), internal air quality assessment, collection of data related to inhabitants behaviours, etc..The REEB coordination action (European strategic research roadmap to ICT enabled Energy-Efficiency in Buildings and construction), as a European R&D technology roadmap initiative (achieved in the context of an EC-funded Coordinated Action - http://www.ict-reeb.eu) has identified ICT contributions to the energy efficiency of buildings mainly via improvement (and corresponding RTD) in integrated design (and indeed ICT tools for Energy-Efficient design and production management), integrated and intelligent control, user awareness and decision support to various stakeholders throughout the whole life of buildings, energy management and trading, and integration technologies. As far as the integrated / intelligent control field is concerned, REEB has fundamentally identified the following areas for future investigation:• automation & control: system concepts, intelligent HVAC, smart lighting, ICT for micro-generation & storage systems, predictive control;• monitoring: instrumentation: smart metering;• quality of service: improved diagnostics, secure communications;• wireless sensor networks: hardware, operating systems, network design.The paper will first introduce to expectations, requirements and potential future scenarios for ICT to support integrated and optimised control in future so-called smart buildings. It will then introduce to the current trend of developments at CSTB in this area, and will present the CSTBox as a tool federating and/or complementing functions (potentially relying on already installed systems) in the built environment. After a short presentation of the REEB project, the paper will follow up with exhibiting the outcome of the REEB project in terms of roadmapping RTD activities in this technological field, also providing with a first insight of their potential impact in the future.Acknowledgement: the authors wish to thank the European Commission (DG INFSO) for its financial support to the REEB co-ordinated action. Moreover, the authors are also grateful to the REEB Consortium partners, namely ARUP, ACCIONA, CEA, LABEIN, TUD, UCC & VTT.

Dynamic System Architecture for Energy Efficient Building Operation: A Case Study of Kiptas Residential Building

Abstract: Buildings account for almost 40 percent of total energy in Europe. Holistic monitoring and analysis methodologies can reduce this by up to 30%. However, the adoption of monitoring and control systems for building management and control applications is hampered by the unavailability of appropriate tool environments. In this paper an integrated model-driven approach that automates the design from component to application level will be presented to provide optimized building operations. The aim is to create a holistic environment for wireless embedded monitoring and control systems to increase the efficiency of the overall system development process and to exploit their potential for reduction of building energy consumption. To reach this objective, new methods, tools and equipments were researched and integration methods covering integrated design, energy simulation models and data warehouse technologies were developed. The findings were applied to a residential building of Kiptas in Istanbul, Turkey and possible energy saving improvements were suggested.

Assessing the Effectiveness of Virtual Environments for Learningthe Fundamentals of Surveying and Construction Layout: Initial Findings

Abstract: The practice of Surveying and Construction layout is one of the fundamental skills that need to be acquired by an engineering or construction management student. Mastering these skills require extensive training with the equipment and team members in order to achieve both precision and accuracy in measurements. In additional to getting used to the equipments, the mastering of the technique requires the students to follow procedures accurately. This paper presents the results of testing a surveying and construction layout game. The game is a first step in a plan to develop a Virtual Reality VR surveying education tool, where students will practice by interacting with a real time computer generated imagery (CGI).The test involve students who have been enrolled in the surveying class for the spring semester 2010. The students are asked to perform a specific surveying task. The students attempts are documented based on their ability to follow the correct procedures and on their ability to choose the correct needed equipment. The paper will show the results of the students ability to follow the correct procedures needed to achieve the appropriate level of precision and accuracy. The results of this test will help make the case that Virtual Reality tools can reinforce the learning of hands on classes such is the case for Surveying and Construction Layout.

Old and at Home in an Intelligent Environment

Abstract: Due to the rapid aging of the Dutch population and aging-in-place policies, an increasing demand for suitable dwellings is to be expected. A significant contribution can be provided by domotics defined as: the advanced technological equipments and services in the domestic environment to sustain and to enhance the quality of aging in place as well as empowerment of the senior citizen (in daily life). This paper, based on literature review and qualitative and quantitative studies, (i) seeks to inform the development of domotics technology in the living environment of the older adults; (ii) provides an overview of the multiplicity of needs and attitudes of the older citizens regarding smart technology in the domestic environment; and (iii) develops recommendations to incorporate domotics in the architectural structure of the dwelling. Study to senior citizens’ needs and attitudes toward domotics is based on triangulation of cohort-group discussions, enabling techniques and in-depth interviews followed by a postal questionnaire survey. Hence, based on the identified needs, two houses, occupied by the elderly, have been upgraded by domotics. The findings indicate that needs, perceptions, environmental and personal attributes of the senior determine the attitudes towards automation. This attitude can best be described as ‘critical/positive’. Too much automation is undesirable. Ethical considerations are particularly related to professional stakeholders, especially caregivers, whereas seniors are mainly interested in the functionality of domotics. In the elderly housing, the stage of stand-alone devices is outdated. It should be focused on the networked home and the integration of domotics in the house. Innovation by addition in a traditional construction environment often results in sub-optimal solutions. The results confirm that the integration of intelligent technology in a house needs to be a synthesis of the user’s needs, technology, the living environment and healthcare.

A model driven Building information managment system forlow enregy building operation

Abstract: Wireless monitoring and optimisation of buildings energy consumption is of central importance for the renovation and energy-efficient operation of buildings since it allows the identification and correction of inefficient energy usage. However, the adoption of monitoring and control systems for building management and control applications is hampered by the unavailability of appropriate tool environments. In this paper an integrated model-driven approach that automates the design from component to application level will be presented to provide optimized building operations. The aim is to create a holistic environment for wireless embedded monitoring and control systems to increase the efficiency of the overall system development process and to exploit their potential for reduction of building energy consumption. To reach this objective, new methods, tools and equipments were researched and integration methods covering integrated design, energy simulation models and data warehouse technologies were developed.
