Physical Modeling of a New Complex System for Sustainable Buildings

摘要

After an extensive study concerning the problem of ventilation buildings and building elements, in terms of comfort and air quality, but also in terms of energy efficiency, was born the idea of independent specific combination of passive buildings in a new concept – permanent garden-fa?ade. This complex system with many advantages in the mentioned above directions, consists in a double glazed fa?ade with an integrated vertical garden and a well coil Canadian/Proven?al coupled to inside of the ventilated fa?ade, which in turn can be continued with a roof channel ventilated roof structure. This system could be tested experimentally by constructing a physical model that simulates the natural circulation of air through a Canadian/Proven?al tube well connected to a ventilated fa?ade and roof channel. Results of measurements on the physical model shows that air only flows through the system due to temperature differences between inside and outside of ventilation duct.
