The simulations of the thermal performance of retrofitted existing residential buildings in Istambul with micro-DOE-2.1E

In this study, the thermal performance of the external envelope of existing residential buildings in Istanbul and energy efficient retrofitting of these buildings are being investigated and modelled by MICRO DOE-2.1E. Hour-by-hour weather data for Istanbul and the data to describe each type of the existing residential buildings as well as the data for energy conscious alternative retrofitting systems are prepared. In the simulations, the thermal performance of interior and exterior insulation systems are verified for a selected reinforced concrete residential building block representing the typical characteristics of the residential buildings in Istanbul. The developed alternative solutions for the external envolopes with opaque and transparent components are being simulated. Finally, the alternatives for retrofitting the residential building block is compared and the solutions and the performance of the computer program are discussed
