The SSHARE project will develop innovative self-sufficient envelope for buildings aimed at net zero energy, thereby contributing to the European technology. Envelope is a combination of two breaking through technologies: HUNTER-Humidity to Electricity Convertor and Advanced Radiant Panel for Buildings that will cool or heat the building, depending on the time of year, imitating perspiration of living beings and using only water as both thermal and electric energy supply. Successful realization of the project is assured by implementing a coordinated network of knowledge sharing in materials science, chemistry and mechanical engineering; by solidifying the state-of-the-art understanding in nanoelectronics and energy efficiency, and by applying bottom-up nanoengineering approaches via an international and inter-sector collaboration of highly qualified researchers from Portugal, Spain, Ukraine, Belarus, Tajikistan, Uzbekistan, Azerbaijan and the Joint Institute for Nuclear Research Russian Federation. Technological (panels fabrication) as well as fundamental (renewable energy) issues will be assessed by this multidisciplinary consortium. This paper explains the basis and principles for the development of a new generation of building materials and hence the creation of net zero building. Sharing the culture of research and innovation, the SSHARE project will allow applying recent advancements in nanotechnology science and mechanical engineering to address ““Plus Energy Houses”” EU 2050 concept.”.

The recast of the European Directive on Energy Performance of Buildings introduces the concept of nearly Zero Energy Building. To obtain a practical interpretation of this building concept, it is necessary to clarify two main issues: (i) how it is possible to select a reliable and agreed upon concept of “zero energy”; (ii) which technological features might be used to reach that target. In order to test the design of a nearly Zero Energy Building in the South of Europe, we present as case study an Italian Passivhaus located in the Po Valley that has been monitored for 18 months and analyzed through dynamic simulations of calibrated models. In this paper we present a selection of the result of the monitoring and simulation phases regarding the contribution (in terms of reduction of the indoor operative temperatures) of Earth-to-Air Heat Exchangers and natural ventilation strategies to meet different summer thermal comfort targets and consequently to avoid the installation of an active cooling system.

The United States Military Academy has been charged with reaching Net Zero Energy consumption by 2020. Feasibility assessments to this point have neglected the field facilities used for military training, which are remote locations susceptible to power loss and subject to a higher rate structure for electricity than the rest of the installation. An energy security analysis methodology is described and applied to the training camps at West Point. This began with identifying the mission of the camps and critical power needs based on discussions with the customer, the Director of Cadet Military Training. Details of power and energy usage along with supply and delivery cost structure were provided by the utility and the facility Energy Manager. Conventional and renewable resource potentials were assessed to meet the load profile within financial constraints and funding opportunities unique to a federal government agency. The final recommendation is to incorporate three different technologies: a 50 kW photovoltaic solar system installed through a power purchase agreement, two small scale hydropower systems totaling 30 kW, and a lake based cooling system to provide air conditioning. The installation of these three systems would move the installation closer to the Net Zero Energy goal and lower the energy requirements to provide cooling. Altogether the proposed project would pay back in 16 years with an expected lifespan of 20–30 years. Batteries, generators, and pumped hydro were also examined as possible energy storage options and to shave the peak electrical load. However, the lack of on peak/off peak pricing made these options less viable. These recommendations will increase West Point’s energy security, progress towards the Net Zero Energy goal, and provide cost savings over current utility expenditures.

Abstract: The house is one of the primary needs of man, so planning the construction of houses should be careful and consider many things. Some of them, namely the potential physical and socio-cultural potential. Physical potential is considered to be the building materials, the local climate and geological conditions. Mean while, social and cultural potential consists of local architecture and way of life. Related to the issue of global warming that occurred in modern times, the climate becomes a major consideration that needs to be resolved.Energy waste is also caused by the design of the buildings are not well integrated and not even one responsive to aspects of functionality, wet tropical climate of Indonesia. This is compounded designers are more concerned with aesthetic aspects (the prevailing trend). Issues green concept and the efficiency of energy consumption through the program Net-Zero Energy Buildings (NZE-Bs) of the housing sector as respon to tackle global heating-an already familiar in Indonesia, although its application can not be found significantly. Green concept by houses an developers often only as a mere trick and not realized and grown the responsibility of residents. Key word: socio-culture, Net-Zero Energy Buildings, energy consumption. Abstrak: Rumah merupakan salah satu kebutuhan utama manusia, sehingga perencanaan pembangunan rumah harus cermat dan mempertimbangkan banyak hal. Beberapa di antaranya, yaitu potensi fisik dan potensi sosial budaya. Potensi fisik adalah pertimbangan akan bahan bangunan, kondisi geologis dan iklim setempat. Sedangkan, potensi sosial budaya terdiri atas arsitektur lokal dan cara hidup. Terkait dengan isu pemanasan global yang terjadi pada masa modern ini, iklim menjadi sebuah pertimbangan utama yang perlu diselesaikan.Pemborosan energi disebabkan oleh desain bangunan yang tidak terintegrasi dengan baik bahkan salah dan tidak tanggap terhadap aspek fungsi, iklim tropis basah Indonesia. Hal tersebut diperparah kecende­rungan para perancang yang lebih mementingkan aspek estetis (tren yang berlaku). Isu-isu konsep hijau dan efisiensi konsumsi energi melalui program Net Zero-Energy Buildings (NZE-Bs) dari sektor perumahan sebagai res­pon untuk menanggulangi pemanas­an global sudah tidak asing di Indo­nesia, walaupun penerapannya ma­sih belum dapat ditemukan secara signifikan. Konsep hijau yang dita­warkan oleh pengembang perumah­an seringkali hanya sebagai trik pe­masaran belaka dan tidak diwujudkan serta ditumbuhkan tanggung jawab para penghuni untuk menja­ganya. Akibat minimnya pemaham­an mengenai konsep hijau tersebut, para pengembang perumahan cen­derung lebih banyak menawarkan lingkungan perumahan yang asri dan hijau, bukan konsep hijau yang sebenarnya. Kata Kunci: Sosial budaya, Net-Zero Energy Buildings, Konsumsi Energi

The paper presents an intelligent building (IB) development strategy emphasizing the locally available non-polluting renewable energy resources utilization. Considering the immense complexity of the topic, the implementation strategy of the main energy-flow processes is unfolded, using the net zero-energy building concept (NZEB). Noticeably, in the first research steps the mathematical background of the considered NZEB strategy has been developed and presented. Then careful LabView software-based simulations prove that the adopted strategy is feasible for implementation. The result of the above mentioned research efforts is a set of powerful and versatile software toolkits well suitable to model and simulate complex heating, ventilation and air-conditioning processes and to perform energy balance performance evaluations. Besides the elaborated mathematical models, concrete software implementation examples and measurement data also is provided in the paper. Finally, the proposed original models offer a feasible solution for future developments and research in NZEB applications modelling and simulation purposes.
