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.

“…Energy storage systems should be developed when the building and the air quality inside the building should be evaluated according to the climatic conditions [34]. In addition to natural factors, technical obstacles, the inadequacy of infrastructure, lack of governmental and institutional support, standardization and lack of public awareness are among the reasons that make it difficult to implement such building designs [35]. In Figure 1, the mentioned properties of positive energy buildings are shown schematically.…”

Considering the rapid depletion of natural resources because of increasing comfort conditions in living spaces and increasing expectations from buildings due to developing technology and climate change, today it has become inevitable to develop effective policies to meet the energy demand of buildings and to create renewable and sustainable systems. In this context, new generation building design in architecture requires regulations that reduce energy consumption, protect natural resources while considering climatic conditions and carbon emissions. In this study, buildings with net-positive energy were evaluated with the comparative analysis method and inferences were made for new generation building designs. In the first step, the properties of buildings with net-positive energy are discussed. Then, it is aimed to evaluate the buildings in which the design principles determined for a positive energy building are applied according to these features. In this context, ten buildings, which can produce more energy than the energy they consume and whose designs were made by considering the energy criteria developed according to different climatic regions, were examined. It is aimed the outcomes of this study to raise awareness against building design concepts with net-positive energy and contribute to raise the number of buildings designed with energy concepts.

“…When moving to the district level, or analysing a set of interconnected buildings, it is important to examine qualitative aspects [33] such as a shortage of professionals, lack of public knowledge, or insufficient governmental and institutional support. Other challenges to be overcome include economic and financial feasibility, and other legal, regulatory, environmental and cultural/social aspects [34]. Holistic studies that combine quantitative and qualitative methods may be of help when it comes to communication with the various stakeholders and can, for example, provide evidence to support the introduction of PEDs as a central concept in urban action plans [25].…”

A rise in the number of EVs (electric vehicles) in Europe is putting pressure on power grids. At an urban scale, Positive Energy Districts (PEDs) are devised as archetypes of (small) urban districts managing a set of interconnected buildings and district elements (lighting system, vehicles, smart grid, etc.). This paper offers a comprehensive analysis of the impact of e-mobility in a PED, simulated using MATLAB-Simulink software. The PED, a small district in northern Spain, is assessed in five scenarios representing varying requirements in terms of energy efficiency of buildings, type of street lighting and number of EVs. The results suggest that the energy rating of the buildings (ranging from A for the most efficient to E) conditions the annual energy balance. A PED with six interconnected buildings (3 residential and 3 of public use) and 405 EVs (as a baseline) only achieves positivity when the buildings have a high energy rating (certificate A or B). In the most efficient case (A-rated buildings), simulation results show that the PED can support 695 EVs; in other words, it can provide nearly 9 million green kilometres. This result represents a potential 71% saving in carbon emissions from e-mobility alone (as compared to the use of fossil-fuel vehicles), thus contributing a reduction in the carbon footprint of the district and the city as a whole.
