Rising living standards have led to a significant increase in building energy consumption over the past few decades. Therefore, along with sustainability requirements, it is essential to establish an effective and precise energy demand model for new buildings. In principle, energy demand in buildings is very important plan to pre-calculate and that is one of the reasons why it is supposed to be precalculated for most of the sustainable buildings. Net Zero-Energy Buildings (NZEBs) have received increased attention in recent years as a result of constant concerns about energy supply constraints, decreasing energy resources, increasing energy costs and the rising impact of greenhouse gases on world climate. Promoting whole building strategies that employ passive measures together with energy efficient systems and technologies using renewable energy became a European political strategy following the publication of the Energy Performance of Buildings Directive recast in May 2010 by the European Parliament and Council. In Net Zero-Energy Buildings (NZEB) is necessary to calculate all factors that influence on energy need for heating. However what is still underestimated is the consideration that the energy performance of any building component is the result not only of its thermophysical properties but also of how are all the components installed and connected to each other. Thermal bridging in buildings can contribute to a multitude of problems. One of the details that create thermal bridges is balcony. This paper is focused to calculate Balcony systems (isokorb) impact on energy need for heating and economic valuation of balcony systems in residential building.

Net-zero energy buildings (NZEBs) were proposed as a viable solution for reducing building energy usage and contamination emission levels. To achieve the desired specific objective, the setups and abilities of the deployed RES in NZEBs should be carefully chosen. The goal of this project is to develop an optimized design approach for a zero-energy building that takes into account the building's usage of energy. The continuous expansion of international energy demand as a result of industrialization and growing populations is presently a major source of concern.

Buildings and the mobility sectors are the two sectors that currently utilize large amount of fossil-based energy. The aim of the paper is to, critically analyse the integration of electric vehicles (EV) energy load with the building’s energy load. The qualitative and quantitative methods are used to analyse the nearly/net zero energy buildings and the mobility plans of the Europe along with the challenges of the plans. It is proposed to either include or exclude the EV load within the building’s energy load and follow the emissions calculation path, rather than energy calculation path for buildings to identify the benefits. Two real case studies in a central European climate are used to analysis the energy performance of the building with and without EV load integration and the emissions produced due to their interaction. It is shown that by replacing fossil-fuel cars with EVs within the building boundary, overall emissions can be reduced by 11–35% depending on the case study. However, the energy demand increased by 27–95% when the EV load was added with the building load. Hence, the goal to reach the nearly/net zero energy building target becomes more challenging. Therefore, the emission path can present the benefits of EV and building load integration.

Net Zero-Energy Buildings (NZEBs) have received increased attention in recent years as a result of constant concerns about energy supply constraints, decreasing energy resources, increasing energy costs and the rising impact of greenhouse gases on world climate. Promoting whole building strategies that employ passive measures together with energy efficient systems and technologies using renewable energy became a European political strategy following the publication of the Energy Performance of Buildings Directive recast in May 2010 by the European Parliament and Council. However designing successful NZEBs represents a challenge because the definitions are somewhat generic while assessment methods and monitoring approaches remain under development and the literature is relatively scarce about the best sets of solutions for different typologies and climates likely to deliver an actual and reliable performance in terms of energy balance (consumed vs generated) on a cost-effective basis. Additionally the lessons learned from existing NZEB examples are relatively scarce. The authors of this paper, who are participants in the IEA SHC Task 40-ECBCS Annex 52, “Towards Net Zero Energy Solar Buildings”, are willing to share insights from on-going research work on some best practice leading NZEB residential buildings. Although there is no standard approach for designing a Net Zero-Energy Building (there are many different possible combinations of passive and efficient active measures, utility equipment and on-site energy generation technologies able to achieve the net-zero energy performance), a close examination of the chosen strategies and the relative performance indicators of the selected case studies reveal that it is possible to achieve zero-energy performance using well known strategies adjusted so as to balance climate driven-demand for space heating/cooling, lighting, ventilation and other energy uses with climate-driven supply from renewable energy resources.

Net Zero Energy Buildings

Zero energy consumption. The goal sounds simple and is presented excessively in variations all over the world. Energy and environmental politics demand zero consumption as a long-term goal, marketing has discovered the concept and first buildings and settlements aiming at balanced energy or emission budgets have been constructed. As an example, the German Federal Government specifies in its fifth energy research programme (2005): For new buildings, the goal is to reduce the primary energy demand, i.e. the energy demand for heating, domestic hot water, ventilation, air-conditioning, lighting and auxiliary energy, again by half compared to the current state of the art. The long-term goal is zero-emission buildings. England and the USA aim for zero carbon developments and net-zero energy buildings (DOE, 2009) in political programmes. The Vatican accepted the offer of climatic “indulgence”—and thus became the first country in the world to completely compensate its carbon emission (Spiegel online, 2007). Megaprojects in the growth regions of the Arabian Gulf and China advertise with a CO2-neutral balance. A Zero Carbon Community is to be created in Masdar, Abu Dhabi (Foster, 2007), and the first Chinese carbon-neutral ecocity was planned for Dongtan, Shanghai (Pearce, 2009). Not only to aid international communication, but also to further the processes required to solve energy-related problems, it is essential that key words, central concepts, their usage and their relationships be clarified. This article intends to contribute to this clarification based on the monitored example of a solar estate. Net zero energy building, equilibrium building, carbon neutral city—the accounting method varies, depending on motivation and point of view. If the focus is on finite and scarce resources, energy is the currency; CO2-equivalent emissions are considered if global warming and public health is the issue; the cost of energy is what concerns a tenant paying for heating and electricity. A balance in one set of units can be converted to another, but the conversion factors often also shift the balance point. Energy will be used as the reference quantity in the following article, which prevents confusion with non-energy measures (e.g. carbon credits for forestry) and avoids the nuclear power debate, in which nuclear power is partly calculated as being CO2 neutral. The diversity of concepts is an indicator that a scientifically based methodology is still lacking, though initial publications focus hereon (Pless et al. 2009). Since October 2008, a group of experts in the International Energy Agency has been addressing this issue under the heading, Towards Net Zero Energy Solar Buildings (Riley et al. 2008). The goal is to document and analyse outstanding examples that are close to being net zero-energy buildings, and while doing so, to develop the methodology and tools for working with such buildings. The Chair of Technical Building Services, University of Wuppertal, is co-ordinating the methodological work. The zero-energy approach—still under construction—will here be presented using a solar estate as an illustration.
