“…One of the ways to reduce energy consumption was identified as reducing the impact intensity per energy unit, achieved by using renewable energy generation locally and by the public energy supply, which aligns with the energy positive case studies used in this research project. Meanwhile, Kosai and Tan [47] present a study of zero energy buildings from an energy trilemma perspective, finding that on-grid zero energy buildings with renewable energy delivered a better performance than off-grid zero energy buildingsalso aligning with energy positive buildings developed as part of this research project. Roaf and Nichol [48] advocate a change in design thinking back to more environmentally adaptive design of buildings.…”

This paper discusses information from a research project investigating a new approach to designing energy positive buildings that integrate renewable energy generation into the building fabric. Such buildings can help reduce energy consumption and associated carbon emissions, alleviating fuel poverty and lessening the need for costly grid upgrades. The main purpose of this study is to highlight the current status of the UK construction industry and the need for improvements, which have been documented over the years. Several enablers for the construction industry to change are identified, including collaborative procurement methods, building information modelling (BIM), innovation and energy positive buildings. The key findings from the review provide evidence that the energy positive solutions put forward in this research project, linking collaboration, innovation and buildings with reduced energy use and carbon emissions, could be used to improve the overall performance of the construction industry. This provides a good knowledge base for the next phase of the research, which includes interviews and workshops with construction industry stakeholders to further identify the challenges, benefits and drawbacks of the potential building integrated energy positive solutions. The combined body of information gleaned from this literature review, the feedback from construction industry stakeholders, and case studies of energy positive buildings designed by the first author, will be used to aid the development of the proposed outcomes of the research project, which will include a continuous improvement tool, the case studies themselves and the development of an innovation portal.

“…En casos donde se cuenta con baterías de almacenamiento de energía, la energía eléctrica para el funcionamiento del edificio se extrae desde tres fuentes: renovables intermitentes (por ejemplo, Solar Fotovoltaica); batería de almacenamiento de energía; e infraestructura externa. La suma de energía entre ellas es consumida por la demanda solicitada (Kosai y Tan, 2017).…”

“…Los ZEB prometen ser una herramienta fundamental para lograr la descarbonización del sector edilicio (Kosai y Tan, 2017;Xing, Hanaoka, Kanamori y Masui, 2018). Su funcionamiento está basado en que, mediante una alta eficiencia energética edilicia, con el uso de tecnologías de producción de energía con fuentes renovables, este sea capaz de igualar o, incluso, superar el consumo que requiere el edificio en un período anual (Berardi, 2018;Lund, Alberg, Connolly y Vad, 2017).…”

Zero Energy Buildings (ZEB) promote a comprehensive view of sustainable architecture and a profound change in the way to build. Research and development in energy transition must necessarily face technological and socio-economic issues. In that line, the goal here is to offer a response to minimize the building sector’s energy and environmental impact. To this end, a review of the state of the art of the subject was carried out, where 97 scientific articles from a period comprising 2006 to 2020, considered the most pertinent, were selected. The methodology consisted of analyzing these texts based on ten questions formulated to address the subject: their origins, current status and future projections regarding energy efficiency and sustainability. The questions refer to definitions (Q1), sustainability (Q2), technologies involved (Q3), emissions (Q5), energy (Q4) (Q6) (Q7), regulations (Q8), climate change (Q9), and future projections (Q10). The work allows concluding that ZEB are integrated in a holistic way in the transformation towards a renewable and sustainable future in terms of energy solutions and, in turn, they have the potential to be implemented in different geographical and climatic positions.

“…Furthermore, the analysis could be improved by the inclusion of additional considerations. Firstly, although this paper employs the equal weight, the outcomes of aggregation highly depend on the weighting scheme in the multi-faceted approach, leading to the difficulties of depicting the universal conclusion [73]. Comparative analysis with changing the weighting scheme (e.g., principle component analysis (PCA), analytic hierarchy process (AHP) and data envelopment analysis (DEA) [74]) may improve the evaluation methodologies of material criticality.…”

Given a potential increase in low-carbon power generation, assessing the criticality of metals used for its technologies is of significant importance. While several studies analyzed the metal criticality of an individual technology, the national metal criticality for a wide range of low-carbon power generation technologies and the comparison of overall criticality of each technology have yet to be fully evaluated. Therefore, this study firstly evaluates the criticality of 29 metals used in facilities for renewable energy and highly efficient thermal power generation in Japan and then compares the overall criticality for each technology to identify metals that might impose limitations on these technologies and to discuss measures for removal of factors hindering the spread of low-carbon power generation technologies. It was discovered that solar power generation technology is the most critical technology from the perspective of supply risk due to the use of indium, cadmium and selenium, while wind power generation is the most critical technology from the perspective of vulnerability to supply restriction because of the use of neodymium and dysprosium. A developed approach would have a significant potential to contributing to energy-mineral nexus, which may assist in providing policy implications from the perspectives of both specific metals and technologies.
