BRUSSELS – The 2012 REHVA International Student competition was held in Timisoara, Romania during the REHVA Annual Conference. REHVA is the federation of European Heating, Ventilation and Air-conditioning Associations.
The call of REHVA’s Education Committee under the chair of prof. Dr. ing. Karel Kabele to participate in the international student competition of REHVA brought 8 entries this year. Eight national champions participated in this competition. The presentations and of the posters were all very good concluded Prof Karel Kabele, chair of the Education committee after the presentations. The judges were quite impressed with all the students. None of the candidates is a native speaker so there was an equal playing field for all of them concerning that aspect of the presentation (oral and poster). The winner of this year’s edition is Rik Maaijen from the Technical university of Eindhoven in The Nederlands for his work on “Occupant-oriented energy control by taking the human in the control loop of building systems”.
A novel approach is presented for building comfort control, focused around the occupant. The user influence on building performances increases when we built our buildings less energy demanding. Therefore optimizing the energy efficiency without taking the user into account is not going to be very effective. In the presented bottom-up system approach, the user is the leading factor in the building by taking control of the building services. Custom sensing by smart sensors makes it possible to measure the position of the occupant in the building and to distribute the energy to those spots where needed. As a case study, we monitored, at the 4th floor of an engineering company, the positions of the building occupants and the most important user actions on building performance, electrical appliances. Applying a building model in HAMBase showed great improvements in the reduction of energy usage as a result of a user-centric energy control system, while maintaining the comfort level.

RBc: What we like about this student's paper is how the occupant becomes the center of the design process - as it should be. Once again we don't design for buildings we design for the body.
