The energy of spatiality

Is it possible in our Belgian climate to realize highly energy efficient low-tech buildings with a natural ventilation strategy without heat recovery and heating system, similar to the prototype building be2226 build in Lustenau Austria in 2013 by the architects Baumschlager Eberle? The hypothesis of the present research is “yes”. But what are the principles and parameters we need to deal with to conceive this type of buildings and are the common simulation tools appropriate for it? To find this out, the applicate methodology begins with the understanding of what had been done precisely in the be2226 concept. Go further with the validation of an appropriate dynamic parametric algorithm based simulation tool. Simulation program which runs on two simulated, build and monitored office buildings what allows the calibration of it by the concordance of the results between simulation and monitoring. Once validated the two models runs with investigation on different strategies and parameters. The goal is to find out, for example, if the spatiality with the increase in ceiling height is for real one of the most important conception keys of this type of building? And if this is the case with kind of spatiality allows us to eliminate classic building services? The expected results concern the influence of the paradigm of spatiality on a low-tech energy concept with a high user comfort and reduced global building costs
