Designing a Zero Energy Building (ZEB) requires an optimal choice of the materials of a building envelope. Different material properties and window areas could be selected to generate a set of possibilities of the design of a building, being the demand defined by its thermal characteristics. The energy demand of a building could be produced with renewable systems such as photovoltaic. Moreover, the HVAC (Heating, Ventilation, and Air Conditioning) systems could be selected considering the system cost. The present methodology focuses on finding a balance between investment and low energy consumption for a building, based on an integrated optimization method. Such methodology applies a Tabu search algorithm and a simplified model to select the passive design. Afterwards, active elements of the design, as photovoltaic systems, are selected. Therefore, the methodology faces the problem of estimating the annual energy demand and the life cycle cost. The goal is the design of a building with a large amount of energy generated by renewable energy, to have a ZEB, and in the worst case, a nearly Zero Energy Building (nZEB). This methodology reduces investment, reduces the energy demand and selects the best construction materials, renewable energy, and air conditioning system. The present paper analyzes a set of case studies considering different climatic zones in Spain. The results conclude that the methodology could help builders in the design stage, to find a new design that allows a ZEB with the optimal life cycle cost.

Zero Energy Building

The continuous growth of population in sub-urban areas leads to increasing demand for mid-rise housing. Recent studies found that greenhouse gas emission in Indonesia continues to escalate at an alarming rate, and housing development is considered as one of the greenhouse gas contributors. Zero-Energy Residential Building, a highly energy efficient and low carbon housing design concept, is regarded as the answer for this environmental issue. Application of Zero-Energy Residential Building concept can reach almost zero sites electrical consumption and reduce greenhouse gas emission since this concept utilizes clean and renewable energy sources, e.g. solar cell, to generate electricity independently. However, this design concept has not been implemented widely since the utilization of solar panels, and other energy conservation components are still too expensive. This study is proposed to find out an optimum combination of design parameters that contribute to cost optimization housing design using sequential search algorithm. Comprehensive study literature and experiment using software are applied in this research. Hence, using the parameter combination in designing a mid-rise dense housing and Zero-Energy Building concept can generate optimum life cycle cost performance. As a result, the study concludes that the life cycle cost of optimized mid-rise Zero-Energy Building is better than the conventional mid-rise housing with annual electrical cost saving up to 98 percent.

Utility Companies

During this period of rising energy demand, utility companies are at a certain point in time, unable to satisfy the overall requirements of their entire consumer population. During this kind of situation, the system, which is, at a micro-scale, can also refer to a zero-energy building, which can also be very prominent in solving this problem. Another thing is that cries of non-renewable energy sources and most of the utility companies are majorly dependent on that kind of energy source, and it keeps along with issues of global warming. A renewable energy-based power system can solve this issue.  In this paper, the solution to this problem by introducing the microscale installation of a renewable energy source at the residential level has been presented. For that here, the area selected for this project is located in St. John's, Newfoundland and Labrador, CANADA. Newfoundland is an island; hence, the proposed system would be beneficial here. Building this kind of system is the process of designing, selecting, and calculating the energy demand of equipment and, at last, synchronizing it with the grid to make it as zero energy building. This process depends upon a range of variables, including geographical location, load requirement, and solar irradiation. The required demand, system modeling, simulation, and techno-economic analysis are carried out by BEopt, HOEMR, and MATLAB software.

Zero Energy Building

The building sector is responsible for a substantial part of the energy consumption and corresponding CO2 emissions. The European Union has consequently developed various directives, among which the updated Energy Performance of Buildings Directive 2018/844/EU stands out, aiming at minimizing the energy demand in buildings, improving the energy efficiency of their facilities and integrating renewable energies. The objective of the present study was to develop an analysis on the energy performance, related CO2 emissions and operating costs of the renewable energy technologies implemented within a multipurpose near Zero Energy Building (nZEB). The target building is an existing nZEB called LUCIA, located in Valladolid (Spain). Monitoring data provides the required information on the actual needs for electricity, cooling and heating. It is equipped with solar energy photovoltaic systems, a biomass boiler and a geothermal Earth to Air Heat Exchanger (EAHX) intended for meeting the ventilation thermal loads. All systems studied show favourable performances, but depend significantly on the particular characteristics of the building, the control algorithm and the climate of the location. Hence, design of these strategies for new nZEBs must consider all these factors. The combined use of the PhotoVoltaic PV System, the biomass and the EAHX reduces the CO2 emissions up to 123 to 170 tons/year in comparison with other fuels, entailing economic savings from the system operation of up to 43,000–50,000 €/year.

Green buildings have been gaining in popularity over the past few years in Jordan. This is attributed to environmental and financial reasons directly related to energy consumption and cost. Energy sector in Jordan faces two main challenges which are the fast growing of energy demand and the scarcity of resources to fulfill this demand. Green buildings can save energy by designing them as near Zero Energy Buildings, where they produce amount of energy almost equal the amount of energy they consume. In special cases green buildings can be designed as Net zero energy buildings, where they produce as much energy as they consume. Jordan government encourage people to adopt net zero green buildings by issuing the Renewable Energy and Energy Efficiency Law No. 13 of 2012, that allows selling excessive electricity to electricity companies. Despite these benefits of green buildings, they are not yet the norm in the building sector in Jordan. This can be attributed to the high construction cost of green building compared to traditional one. However, this may not be true if the whole life cycle cost of the building is considered, in which the cost not only include design and construction but also operation and maintenance as well. This paper aims to provide real life cycle cost analysis for a typical residential building in Jordan, and to search different effective building strategies and design scenarios that will lead to a successful near Zero Energy Building. The search will apply main green building strategies recommended for Jordan climatic zone. The outcome of this study is a list of best economically feasible design solutions and system selections that result in near Zero Energy Building in Jordan for residential buildings.

Abstract The recast of the Energy Performance Building Directive contains a new article about the need to increase the number of buildings which go beyond current national requirements, and to draw up national plans for increasing the number of nearly zero-energy buildings (nZEB) with the final target that by 2020 all new buildings shall be nearly-zero energy. Nearly zero-energy buildings are buildings with a very high energy performance, where the remaining low energy demand can be supplied to a significant extent by renewable energy. In this paper, a detached house complying with the proposed Hungarian nZEB requirements is analysed. The life cycle cost and life cycle environmental impacts of the building are assessed for various building service systems to optimise the building design.

Industri konstruksi dan bangunan bertanggung jawab atas lebih dari 35% konsumsi energi di dunia dan menghasilkan hampir 40% emisi gas rumah kaca seperti CO2. Emisi CO2 berasal dari konsumsi energi bangunan dimana lebih dari 65% yang masih bersumber dari bahan bakar fosil. Near Zero-Energy Building (nZEB) adalah sistem bangunan yang memiliki efisiensi energi tinggi dan dapat menghasilkan listrik secara mandiri dari sumber energi terbarukan, sehingga mengurangi biaya operasional dari tagihan listrik tahunan secara signifikan di dalam umur pakainya. Pembangunan berkonsep ini akan menambah biaya konstruksi awal untuk penerapan desain hemat energi dan sistem pembangkit energi terbarukan pada bangunan. Kelayakan finansial bangunan dengan desain seperti ini diukur dengan metode analisis Life Cycle Cost yang juga memperhitungkan biaya operasional sepanjang umur pakainya. Insentif energi terbarukan merupakan faktor penting dalam analisis kelayakan finansial karena insentif ini secara langsung mengurangi biaya operasional (biaya listrik tahunan) bangunan. Kementerian Energi dan Sumber Daya Mineral (ESDM) telah menerbitkan peraturan baru mengenai besaran insentif yang diberikan kepada pemilik bangunan yang memasang pembangkit listrik dari sumber terbarukan. Perlu ada kajian mengenai dampak finansial dari diterbitkannya peraturan baru ini terhadap nilai finansial nZEB sebagai sebuah sistem bangunan utuh yang terintegrasi dengan pembangkit energi dari sumber terbarukan, terutama bangunan pemukiman padat. Tujuan dari penelitian ini adalah membandingkan kelayakan finansial nZEB yang menggunakan peraturan tahun 2013, dengan Peraturan Kementerian ESDM no. 49 tahun 2018, pada bangunan pemukiman padat berkonsep desain nZEB. Penelitian ini menemukan nilai kelayakan finansial konsep desain nZEB di bawah peraturan insentif tahun 2013 lebih besar daripada di bawah peraturan tahun 2018.
