In this paper, we investigate the economic benefits of an energy community investing in small-scale photovoltaics (PVs) when local energy trading is operated amongst the community members. The motivation stems from the open research question on whether a community-operated local energy market can enhance the investment feasibility of behind-the-meter small-scale PVs installed by energy community members. Firstly, a review of the models, mechanisms and concepts required for framing the relevant concepts is conducted, while a clarification of nuances at important terms is attempted. Next, a tool for the investigation of the economic benefits of operating a local energy market in the context of an energy community is developed. We design the local energy market using state-of-the-art formulations, modified according to the requirements of the case study. The model is applied to an energy community that is currently under formation in a Greek municipality. From the various simulations that were conducted, a series of generalizable conclusions are extracted.

So far, China’s particulate pollution control is principally focused on primary particles and sulfur dioxide from coal combustion. The contribution of ammonia emissions to particulate matter with an aerodynamic equivalent diameter of less than or equal to 2.5 microns (PM2.5) has been increasingly emphasized. As a world-famous agricultural country with 523 million farmers (2017, National Bureau of Statistics of China), approximately 70.0–90.0% of China’s ammonia emissions come from agriculture. With such a huge population, agriculture industrialization (socioeconomic policies and technology upgrades to reduce ammonia emissions from fertilizers and livestock) has a large potential but is more vulnerable to costs compared to other industries. We need a solution involving both economic benefits and environmental protection. For this purpose, we sent out an anonymous questionnaire consisting of 16 questions to 420 farmers and conducted a field visit survey in a rural area of Jiangsu Province. Through statistical analysis, we found that the use of nitrogen fertilizers in agriculture, which are an important source of ammonia through volatilization, is normal (200/420 × 100% = 47.62% of farmers use such fertilizers). Among the 420 farmers surveyed, 90.71% of them have knowledge of air pollution from agricultural activities and 92.15% of them have certain understanding of agricultural industrialization policies, indicating that coordinated control of ammonia emissions can be achieved together with policy propaganda. Through factor analysis and correlation analysis, we find that the early propaganda of policies can help farmers to be more willing to accept the policies. The correlation coefficient between awareness of pollution and policy approval is 0.94, and that between policy publicity and policy approval is 0.95. Generally speaking, the promotion of policies is worth carrying out during the implementation process.

To transform the negative impacts of buildings on the environment into a positive footprint, a radical shift from the current, linear ‘make-use-dispose’ practice to a closed-loop ‘make-use-return’ system, associated with a circular economy, is necessary. This research aims to demonstrate the possible shift to a circular construction industry by developing the first practical framework with tangible benchmarks for a ‘Circular University Campus’ based on an exemplary case study project, which is a real project development in India. As a first step, a thorough literature review was undertaken to demonstrate the social, environmental and economic benefits of a circular construction industry. As next step, the guideline for a ‘Circular University Campus’ was developed, and its applicability tested on the case study. As final step, the evolved principles were used to establish ‘Project Specific Circular Building Indicators’ for a student residential block and enhance the proposed design through bioclimatic and regenerative design strategies. The building’s performance was evaluated through computational simulations, whole-life carbon analysis and a circular building assessment tool. The results demonstrated the benefits and feasibility of bioclimatic, regenerative building and neighbourhood design and provided practical prototypical case study and guidelines which can be adapted by architects, planners and governmental institutions to other projects, thereby enabling the shift to a restorative, circular construction industry.

This study aims to examine the features of the creation and operation of ecomuseums at wide-area and (metropolitan) local government levels and to analyze their improvements and limitations based on an analysis of a case study on the “Gyeonggi Bay Ecomuseum.” This study also reveals the necessity and direction for ecomuseums led by metropolitan local governments. It attempts to find ways to expand the Gyeonggi Bay Ecomuseum and apply lessons from this ecomuseum to other planned wide-area ecomuseums in South Korea. Overall, this study intends to derive the sustainability of wide-area ecomuseums, and their utility and potential as a means to revitalize the region.  The Gyeonggi Bay Ecomuseum is a meaningful case study as it was created in a wide area called the Gyeonggi Bay and was led by a metropolitan local government, along with the official claim as an ecomuseum; the museum creation project also progressed in a phased approach. However, there are issues such as organization problems of the ecomuseum and the absence of resident participation, integrated programs, and an archive center.  Therefore, this study presents measures to overcome these obstacles: the establishment of a core ecomuseum and an exhibition center, the development of joint programs, the continuous security of funds and human resources, and measures to generate economic benefits for residents. This study also suggests spatial/functional expansion from being the “Gyeonggi Bay Ecomuseum” to the “Gyeonggi Province Ecomuseum.”   Keywords: Ecomuseum, Wide-area unit, Lead of local governments, Gyeonggi Bay, Regional revitalization
