A Study on Passive House Potential of Countries-The Case of Germany/ Sachsen Region

Abstract

Today, as a result of energy consumption, CO₂ emissions increased and global climate problems formed with this. At the same time, with the increasing population density, intended for alternative ways to reduce energy dependence started to be sought. As stated in the Energy Performance in Buildings Directive (EPBD), it is significant to design energy-efficient manner buildings that use up approximately 40% of the total energy consumed in Europe.  In Turkey, the scope of energy performance improvement policies in building energy consumption while reducing protecting user well-being, environment and nature of taking attention existing resources are sustainable and cost-effective to exploit away Nearly Zero Energy Buildings (nZEB) were targeted. In addition to ensuring energy efficiency in Passive Houses, it is inevitable to use renewable energy sources. These Passive houses, which provide high comfort conditions with low energy consumption, are important in terms of guiding the designs. The passive home design approach can be a solution proposal for new structures in terms of energy performance as it can apply to existing buildings.  The Passive House design approach can apply to existing buildings something like a solution proposal for new structures in terms of energy performance. Such applications can contribute to energy saving in the transformation studies in countries where the existing building potential is high. In this study, Passive House approaches in Turkey with Europe and other countries were evaluated, criteria that be attention in  Passive House applications were tackled. In this context, three kindergarten samples that meet the features of passive homes in Sachsen, Germany, which have low solar energy potential but the highest passive home potential in Europe, were examined. This study is significant for pilot regions and increase in implement projects in countries with high solar potential like Turkey. At the same time, it can be considered as solution suggestions that can contribute to reducing the damages of climate change.
