Energy efficiency in buildings sector can provide influential solutions to the threats arising from the increase in carbon emissions. Since efficient design of the buildings and equipping them with renewable systems increases the final cost, strategies should be developed to encourage building owners. The first stage of these strategies is certification of these buildings. However, modeling of the buildings equipped with renewable systems is possible with the use of more than one software and requires detailed technical expertise. An easy-to-use software, where all calculations are conducted in a single software, will be useful in the spread of certification processes. For this reason, in this study, an easy-to-use software has been developed that can be used during the certification of zero energy buildings which eliminates the requirement of more than one software. The software makes use of the climate, electricity consumption, building, and renewable system properties data to predict the energy demand and production, and generate zero energy consumption building certificate.The heating demand, photovoltaic (PV) and wind system estimate of the software are verified by using real data and R 2 values are calculated as 0.92, 0.97, and 0.98 respectively. A certificated passive and zero energy consumption building is modeled in the developed software as a case study building and NZEB certificate was awarded to the building by the software. Therefore, in this study, an easy-to-use software is developed and verified to certificate the on-grid zero energy buildings that eliminates requirement of detailed technical knowledge and usage of more than one software.

Good quality dwelling and the environment are related to the values of citizens’ existence. It can be highlighted as important questions in creating a sustainable living environment. The research and analysis carried out so far include global planning of the plot of a particular country or city according to economic aspects. Meanwhile, our model, which covers the key social aspects of choosing a residential house, will fill this gap. We propose an original problem formulated which includes the planning of the plot of a particular city according to economic, environmental and social aspects. Our work aims to investigate the criteria for the selection of single-family houses and to develop a theoretical evaluation model based on decision-making methods. The presented study deals with the problem of selecting a one-family house plot using the Weighted Aggregate Sum Product Assessment Methods (WASPAS) and the Step-Wise Weight Assessment Ratio Analysis Method (SWARA). During the research, parameters related to plot selection were evaluated: infrastructure, distance, cost, privacy, security and aesthetic view.

“…Moreover, about 40% reduction of heating energy demand was predicted for installing new insulation and high efficiency windows in South Korea [76], and a total 15% energy reduction with a payback period of 10.4 years was predicted with the potential measures in residential building in Brazil by Sartori and Calmon [77]. By improving window, wall, and roof systems of single-family houses in Turkey, about 50% of the heating demand can be reduced with favorable payback periods [78]. After selecting a set of retrofit solutions, life cycle assessment is crucial in decision-making process for better promoting the sustainability of the existing building, which is lacking in the current literature [79], and is also not considered in this study.…”

This study aimed to develop a deterministic decision-making mechanism for finding the optimum set of retrofit solutions of existing high-rise residential buildings in two different climatic zones of China. The retrofit solutions were critically examined with different energy saving targets based on the local climatic conditions, building features, and retrofit costs in cold and severe cold zones comparatively. By making the extensive review and analyzing considerable statistics data and cost information, net present value (NPV) method was employed in the prototype building apartments to develop this deterministic model. The results demonstrated that the heating system is the most important factor in saving energy and obtaining the optimum revenue in these two regions. The highest optimal NPV can be obtained by achieving 60% energy saving in the cold zone, as energy saving is around 319 kWh/m2/year with the total retrofit costs of USD $3560, while it is 281 kWh/m2/year with the total retrofit costs of USD $3480 to achieve the 50% energy-saving target in the severe cold zone. Based on the analysis of energy savings and retrofit costs, the results can be effectively implemented for the purpose of creating sustainable retrofits in existing buildings, and the model can be adapted for selecting appropriate retrofit choices in other climatic zones.
