Eco-construction. University & Industry Technology Day

Tuesday, 13 May, 2008 - 09:00 to Tuesday, 13 May, 2008 - 15:00
Campus: Brussels Humanities, Sciences & Engineering campus

At the Vrije Universiteit Brussel, research related to environmental issues is very diverse, including fundamental and applied sciences. Through our research we are tackling the main environmental challenges of the 21st century. Collaboration with industrial partners is essential to further develop applications, thus allowing our R&D to have a tangible impact on society.

The Technology Tranfer Interface therefore organises an eco-construction technology day, an exclusive matchmaking event where industrial and academic players can learn, interact and connect.

The focus will be on several university research topics and applications regarding eco-construction.

9.00 AM - Welcome & Coffee

9.30 AM - Introduction (.pdf)
Jan CORNELIS, Vice-rector Research


9.40 AM - Sustainable building: a multidisciplinary optimisation process with restrictive boundary conditions
Filip DESCAMPS, Architecture
Here you can find more info on the research group.

  • Abstract: When designing a building the client and design team start from a schedule of requirements and gradually translate this schedule into plans and specifications. When establishing the design choices the design team follows a strict method in which each solution is assessed on its intrinsic qualities, its financial feasibility and its interaction with other design aspects. In the lecture we advocate the use of an overall energy performance approach to buildings.

9.55 AM - Material identification by vibration measurements
Massimo BOTTIGLIERI , Mechanics of Materials and Constructions, Vrije Universiteit Brussel / Industriële Wetenschappen & Technologie, Erasmushogeschool Brussel
Here you can find more info on the research group.

  • Abstract: Vibrations offer a fast and cheap possibility to accurately identify elastic and damping properties of structural materials like steel, polymers, composites, glass, wood, concrete … among others. The basic idea of the presented method is that the vibration behavior of test specimens like plates and beams is influenced by the elastic and damping properties of the material. Thus inversely, by observing the vibrations it is possible to estimate the material properties. The so-called “Resonalyser” method computes the elastic and damping behavior of materials from measured resonance frequencies and damping ratios of rectangular test plates. The principle is to compare the observed vibrations with numerical simulations of the test plates. The material parameters in the numerical model are updated in such a way that the computed vibration behavior matches the observations.

10.10 AM - Microgasturbines for CHP (Combined Heat and Power) in large buildings
Jacques DE RUYCK, Thermodynamics
Here you can find more info on the research group

  • Abstract: In this presentation the principle and the potential benefits of combined heat and power systems are first exposed.
    Different criteria for decisions regarding application of CHP in buildings in particular are examined, followed by some technical examples.
    Current research for improvement of CHP economics are presented, such as sizing, trigeneration or heat recovery for extra power.
    The regional and European legislation regarding financial support for CHP systems are briefly discussed.

10.25 AM - Design of easy-to-use tools to measure and evaluate noise and vibration pollution
Patrick GUILLAUME, Accoustics and Vibrations
Here you can find more info on the research group

  • Abstract: The increasing performances of portable consumer electronics such as PDA’s and Smart Phones make such devices suitable to measure and process vibration and acoustical data at low cost. As a case study, an easy-to-use software tool has been developed to calculate the reverberation time of a room based on a time-frequency (octave) analysis of the measured data. The quality of the measurement results of a PDA equipped with the developed software is verified by means of professional measurement equipment.

10.40 AM - New developments of green coatings with multifunctional properties
Jean VEREECKEN, Metallurgy, Electrochemistry and Materials Science
Here you can find more info on the research group

  • Abstract: Metals are often coated with organic films (paints, adhesives...) for
    various applications in packaging, transport, construction, amongst other. Compatibility between the organic medium and the metal substrate covered by its native oxide is crucial for a good adhesion between the metal and the film and required for durable properties.
    A recent development is to purposely replace the native metal oxide surface by a tailored metal oxide and an organic film bonding to the intermediate metal oxide layer.
    Another hybrid system goes a step further: instead of making layered multi-components structures, nano-metal oxide particles are mixed in an organic matrix and deposited as one layer on the metal surface.
    Through the control of materials at the nanometer scale, new innovative structures can be tailored with an improvement of specific properties or, obviously even more interesting, with multi-functional properties
    • appearance, colour, reflectivity, smart colour systems,....
    • corrosion protection and durability: barrier properties against water
      uptake, self-healing properties comparable to chromate conversion,......
    • mechanical and durability: wear resistance, hardness, flexibility, ....
    • adherence and durability: paint adhesion, resistance against underfilm

10.55 AM - Euterpe: a low cost advanced sonometer with integrated intelligence
Abdellah TOUHAFI, Industriële Wetenschappen & Technologie, Erasmushogeschool Brussel
Here you can find more info on the research group

  • Abstract: Euterpe is a Windows-based sound level meter (SLM) developed at the Department IWT of the Erasmushogeschool Brussel. It gives the acoustic expert the possibility to make unmanned, long period, environmental Sound Level measurements while having the ability to access the results and the state of the SLM remotely. The measured sound levels and several (selectable) statistical parameters are calculated and kept in files. The software provides also the possibility to interact with hand-held SLMs in order to extend there measurement-capabilities. Moreover, some additional facilities are integrated in the same software: registration of weather-conditions, wireless sending of acoustic results, time-synchronization between distributed SLMs, network interface to implement distributed measurement networks and a web-application for the data-handling. Installation, calibration and programming are done by a Windows-based user-interface.

11.10 AM - Wind tunnel testing of civil structures
Steve VANLANDUIT, Fluid Mechanics
Here you can find more info on the research group

  • Abstract: Wind tunnel tests and fluid flow visualization experiments are important tools in the aerodynamic design of structures. At the experimental fluid mechanics lab of the Vrije Universiteit Brussel aerodynamic tests are performed for a broad spectrum of applications in different domains ranging from transportation (car design, airplanes) to civil engineering (buildings, wind turbines, bridges) and machine design (combustion, ventilation). In this presentation several representative examples of aerodynamic tests are discussed.

11.20 AM - Industry-university cooperation for safety and reliability - from design to monitoring
Bart PEETERS, RTD Project Manager, LMS International
