“…In another study on insulation thickness, it was found that optimum thickness glass wool and rockwool insulation materials reduce fuel consumption by approximately 70% and 40% [15]. According to Ozalp et al [16], the effect of wall building material on heat losses is much higher than insulation material. Some researchers analysed the impact of innovative façade (double skin façade, BIPV façade, opaque ventilated façade, greenery systems etc.)…”

Due to the increasing energy consumption in the world, energy efficiency has become the most important issue in sectors with high energy use such as industry, transportation, agriculture and construction. In many countries, the energy consumed in housing composes a large part of the total energy consumption. In Turkey, about 20% of total energy consumption is utilized in residential buildings and about 60% of this energy is used for heating. The energy consumed in residence buildings can be reduced by measures to decrease the heating and cooling loads. For this purpose, the main objective of this study is to investigate the effect of ventilated walls on the energy and cost performance of buildings. The energy and cost efficiency of 27 different ventilation walls with 3 different insulation thicknesses, 3 different ventilation gap thicknesses and 3 different cladding materials were compared with the reference wall. For a family of 3, a flat with a 2 + 1 plan was chosen for investigation and the flat is located in Trabzon, which represents the moderate-humid climate region. Flat plans with different ventilated walls were modeled using DesignBuilder energy simulation software and monthly/annual heating and cooling loads were obtained. Then, life cycle cost analysis has been conducted to investigate the cost effective ventilated wall types. Although the high initial investment costs of the investigated ventilated walls increase the life cycle costs, it has been observed that they provide energy savings in buildings.

“…Kullanılan nicel hesaplamalar sayesinde binalar bazında yalıtım kalınlığı bakımından en uygun değerin bulunması ve en tasarruflu yakıt tipinin seçilmesi işlemleri gerçekleştirilebilmektedir. Binalardaki ısı kayıplarının genel olarak pencere açıklıklarından, tavan aralıklarından ve hava akımları etkisiyle oluştuğu birçok araştırmacı tarafından belirtilmiştir [20,21,22]. Bu çalışmada yapılan hesaplamalar sadece dış duvarlardan ısı kaybı olduğu kabul edilerek gerçekleştirilmiştir.…”

Isı yalıtımı konusu global ölçüde önem arz eden ve üzerinde sürekli çalışılan bir alanı oluşturmaktadır. Bu bağlamda, Ağrı ili için dört farklı duvar modeli (taş, tuğla, briket ve betonarme) ve beş farklı yakıt (kömür, doğalgaz, Likit Propan Gaz (LPG), fuel oil ve elektrik) çeşidi seçilerek optimum yalıtım kalınlığı, yalıtım maliyeti, yakıt ve toplam maliyetler, geri ödeme süresi ve yıllık enerji kazancı değerleri hesaplanmıştır. Çalışmada yalıtım malzemesi olarak Genleştirilmiş Polistiren (EPS) kullanılmıştır. En yüksek optimum yalıtım kalınlığı, yakıt maliyeti ve toplam maliyet değerleri elektrik enerjisinin kullanıldığı durumda betonarme duvar modeli için belirlenmiştir. Betonarme duvar modelinde elektrik enerjisi için optimum yalıtım kalınlığı 0.168 m, yakıt maliyeti 3,2392 $/m2 ve toplam maliyet 23,9826 $/m2 olarak tespit edilmiştir. Betonarme duvar modeli için optimum yalıtım kalınlığı, yakıt maliyeti ve toplam maliyet diğer duvar türlerine göre daha yüksek değerler gösterse de geri ödeme süresi bakımından en verimli duvar modeli olduğu belirlenmiştir. Kullanılan yakıt çeşitleri arasında geri ödeme süresi bakımından en verimli olanının elektrik, kömür ve doğal gazın kendilerini en geç amorti edebilen iki yakıt çeşidi olduğu belirlenmiştir.

The development of modern construction requires the use of environmentally friendly building materials, including insulating materials, to ensure the energy efficiency of buildings and structures. The purpose of the work is relevant and was to develop a methodology for assessing the compliance of extruded polystyrene foam with environmental requirements. The problem is that the certification of such materials includes an examination of their physical and mechanical properties and does not allow assessment of materials’ environmental aspects. A comprehensive approach to assessing the quality of extruded polystyrene foam is proposed, which ensures not only the technical level of material quality, but also compliance with environmental requirements. The research methodology is based on the environmental risks’ identification at all stages of production and the determination of products environmental safety criteria. Each criterion is characterized by a set of indicators, among which a representative indicator is determined. A complex indicator is proposed for assessing the environmental safety of the production of extruded foamed polystyrene. The novelty of the work lies in the algorithm for calculating the material environmental friendliness complex criterion. The process model of the extruded polystyrene foam production analyses made it possible to establish representative indicators according to the products’ environmental safety criteria. As a result of the analysis, critical operations were identified where environmental risks are likely, and representative indicators’ limit values were set in accordance with regulatory documentation. Measures have been developed to minimize the release of harmful substances during each critical operation. To improve environmental management, the system for monitoring and assessing risks in the production of extruded foamed polystyrene has been optimized. As a result, a methodology has been developed for assessing the compliance of the production of extruded polystyrene foam with environmental requirements, which is necessary for product quality certification.
