“…When the studies that deal with the issue of external walls in terms of energy are reviewed, it is seen that there are many studies on improving the energy performance of the existing building stock (Valancius, Vilutiene, & & Rogoža, 2018;Matthew & Leardini, 2017;Lassandro & Di Turi, 2017;Biseniece, ve diğerleri, 2017;Rodriguesa, White, Gillott, Braham, & Ishaque, 2018;Liu, Liu, Ye, & Liu, 2018;Xu & Liu, 2018;Poortinga, Jiang, Grey, & Tweed, 2018). Usta compared the insulated and non-insulated walls in terms of energy efficiency according to TS825, since the thermal insulation plays a very important role in the energy efficiency of the building in the usage phase of the wall cross-section (Usta, 2009), Erbil and Akıncıtürk, on the other hand, evaluated the thermal comfort conditions in a mass housing built with a tunnel formwork system, using a survey, thermal camera and TS825 calculation method, and concluded that thermal insulation had to be compulsory (Erbil & Akıncıtürk, 2006).…”

Urban regeneration has accelerated after the establishment of the Law on Transformation of Areas Under Disaster Risk and has been carried out intensively. Building renewal, especially at a parcel scale, cannot deal with environmental problems on an urban scale and accordingly, the sustainability principles cannot be addressed holistically. Since building renewal at a parcel scale affects a large area throughout the city, it is required to include design criteria for environmental impacts. In this context, it is important to reduce heating and cooling energy consumption, which constitutes a large part of the total energy consumed in the use of buildings, and to take environmental measures. This study aims to analyse the energy performance of external walls in new buildings constructed after 2012 in the Suadiye Neighbourhood and to determine the most appropriate wall section. For this purpose, external walls were determined with a field study, and scenarios related to building orientation, the distance between buildings and external wall sections were created on a sample building. The scenarios were analysed with DesignBuilder simulation and TS825 calculation. The results for the scenarios were evaluated comparatively. The study differs from existing studies with its scope by dealing with both building renewal and energy efficiency and analysing the external wall types in different scenarios with DesignBuilder and TS825 for the temperate humid climate zone. As a result of the study, the most suitable wall sections for the scenarios were determined and suggestions were developed. The results of the study contribute to the country's economy by ensuring the efficient use of resources.

Nowadays, it is important to understand how to combine energy efficiency and the point of view of resilience. Regarding buildings, resilience represents the ability to recover from or adapt to an unfavorable condition or event, maintaining their own functionality and performances. This issue has been ignored for several years, especially in building sector, but the impacts of natural hazards and climate change are becoming more and more influential and frequent. Moreover, urban areas are responsible of a great part of global energy consumption and CO2 emissions, in addition to the intensification of greenhouse effect. For this reason, the use of new technologies (PCM and cool materials) for buildings can affect not only indoor microclimate, but also urban environment. Starting from the dynamic simulations of common buildings in South of Italy and then in other hotter Mediterranean climate (Athens, Tunis), the research analyses various typologies of these materials and possible combined applications. The aim of the study is to understand, through a set of proper indicators, how they can contribute to enhance energy performance of buildings and climate resilience in order to face rising temperatures also at neighbourhood level.

“…Panagiotidou et al [ 12 ] assess how the addition of thermal insulation to the building’s envelope, window replacement and implementation of high-performance HVAC systems may impact on a residential building in Greece, in terms of greenhouse gas emissions reduction. Lassandro and Di Turi [ 13 ] assess the resilience of a multi-storey residential building in Bari (Italy) under future climatic conditions when thermal insulation is added to its facades. De Masi et al [ 14 ] study a single-family dwelling of Benevento (Italy) towards climate change, assessing the impact of window replacement, thermal insulation, green roof or external solar shading on energy demand.…”

Global warming will lead to adverse consequences for human health and well-being. This research ought to determine whether passive low-cost strategies freely controlled by users (ventilation strategies, solar shadings or window operation) could be applied in low-income dwellings to meet acceptable thermal comfort to retrofit the Mediterranean social housing stock of southern Spain towards climate change. On-site measurements registered in some test cells (controlled environment with no users’ influence) were used to calibrate dynamic energy simulation models. The impact of several future periods, climate zones of southern Spain and orientations on thermal comfort was assessed. The results show that climate change triggers a more significant increase in outdoor temperatures in summer than in winter. Should ventilation be kept to minimum and blinds opened during daytime in winter, higher comfort would be achieved, with great differences between orientations and south reporting the best results. The higher the outdoor temperatures due to climate change, the higher the percentage of comfort hours (i.e. 23–68% in the present and 50–75% in 2080). In summer, natural night ventilation and blinds closed during daytime lead to the best comfort result, with negligible temperature differences between orientations. Future climate change scenarios worsen the percentage of comfort hours (i.e. 96–100% in the present, while up to 17% in 2080). Mechanical ventilation and blind aperture schedules were found to have the highest influence on overheating discomfort. Likewise, mechanical and natural ventilation schedules had the highest impact on undercooling discomfort.
