Energy performance of smart buildings: simulating the impact of active systems and passive strategies

Tetik, Buğra
Energy efficiency is one of the most important attempts in the world because of various environmental, economical and developmental aspects of energy. In this context, energy performance of buildings has been a critical issue since buildings constitute approximately half of total energy consumption. The concept of smart building which has been attractive recently, contributes to the issue with smart technologies; while some passive design techniques which have been used throughout the history are still applicable for energy saving. The study aims to evaluate not only comparative impact of technological devices and traditional methods, but also energy saving potential of them for locations where heating load is dominant. While researching impacts of various active or passive building components to energy efficiency, the study not only focused on heating load reduction but also lighting electricity saving by use of daylight. Selected various active systems and passive strategies is tested on a base-case module, which is a flat in an existing residential tower in Ankara, by the help of computer based energy simulations. Systems and strategies are selected in the light of literature by considering wide availability in market. During the process, three series of simulation variations including forty-two different scenarios are tested. Only active systems is tested in the first series and only passive strategies in the second. Finally, impact of using both active systems and passive strategies together is tested in the third series.
