High-rise Building Integrated with Solar Chimney and Bioenergy

In dense mega cities, high-rise buildings huge energy consumption on mechanical ventilation and overheat produced by the air conditioners are among big challenges for the sustainable building development and green city construction. Solar chimney is proved to be an efficient method to promote natural ventilation for buildings. Different types of solar chimney are presented with a high-rise building layout example. Solar chimney geometry and environment basic data is suggested to be evaluated to optimize the Solar chimney’s natural ventilation. In addition, aiming as well a clean and sustainable environment, bio-energy can be adopted in buildings by integrating with algae-fluid window and wall system. Different materials of radiation absorber can be studied and integrated with solar chimney. An outline of research on solar chimney integrated with bio-energy for high-rise building is given in this paper. In order to succeed, close multidisciplinary cooperation is necessary for the project which involves at least architecture, thermal physics, air dynamics, materials science and biology. Experiment conditions and potential risk should be discussed beforehand.
