Although most of China’s college students attend ordinary universities, the extant literature regarding China’s green universities is limited to top-tier universities. Based on a case study, this research aims to explore the practice of the greening efforts of an ordinary university through surveying the students’ awareness, expectations, and perceptions about sustainability. This research finds that the students are aware of sustainability to a fair extent, but their awareness comes more from non-university factors (e.g., family education) than university factors. Furthermore, while students have high expectations regarding the university’s efforts to promote sustainability, their perceptions indicate that the university’s sustainability-related performance is poor. This research concludes that China’s ordinary universities need to bridge the gap between students’ expectations and perceptions, which they can do by responding to students’ concerns and by supporting bottom-up approaches of policymaking.","PeriodicalId":51753,"journal":{"name":"Journal of Green Building","volume":"121 16","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138609222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"艺术学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents an application framework for simulating indoor and outdoor wind field and an air conditioning system based on BIM. Through the BIM software with built-in CFD calculation, the indoor and outdoor wind environment is simulated, and it is found that the outdoor vertical wind field has a certain influence on indoor ventilation. Meanwhile, the air conditioning energy consumption of the building is calculated, and the influence of indoor natural ventilation on air conditioning energy consumption is quantified.

EMPIRICAL EVIDENCE FROM BUILT PROJECTS","authors":"Ming Hu","doi":"10.3992/jgb.18.3.61","DOIUrl":"https://doi.org/10.3992/jgb.18.3.61","url":null,"abstract":"ABSTRACT The affordability of sustainable building remains a significant challenge; developers, building owners, and design teams often point to high construction costs as the primary obstacle hindering the uptake of sustainable building. Because of a lack of clarity, empirical studies and evidence supporting the claim of sustainable building as expensive are inadequate, thus the perceived high cost of sustainable building is still debatable. This study has a three-pronged approach: (1) to collect actual construction costs of certified sustainable buildings, (2) to take a deep dive into construction cost using empirical data and analyze the correlation between the level of sustainability and the construction cost, and (3) to examine the influence of cost components on the total construction cost. Data from 72 LEED buildings was collected and included in the analysis. The findings show the following: (a) the construction costs of the studied sustainable buildings are comparable to those of conventional buildings (even lower); (b) the correlation between the level of sustainability and the construction cost is inconclusive; and (c) soft costs, especially the design cost, have a similar level of influence on the total construction cost as those of hard costs.","PeriodicalId":51753,"journal":{"name":"Journal of Green Building","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135298160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"艺术学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes to diagnose LCC performance from a dual perspective in order to identify problematic areas for improvement. The dual perspective refers to management processes (including Plan, Do, Check, and Act) and low carbon city performance dimensions (namely, energy structure, economic development, production efficiency, urban population, water carbon sink, forest carbon sink, green space carbon sink, and low carbon technology). A diagnosis model has been introduced based on the dimension-process dual perspective. The model has been applied for diagnosing the LCC performance in four municipalities in China. It has been found that the performance in the economic development dimension is much better than in other LCC dimensions, and the performance in Plan and Do stages are better than that in other stages. This reflects the traditional practice in China where more attention and resources are often given to urban planning and implementation with less attention to checks and feedback. The findings from this study provide important references for both further research in the discipline and practical application in promoting LCC in other cities.","PeriodicalId":51753,"journal":{"name":"Journal of Green Building","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135298163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"艺术学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study reveals the impact of technology mergers and acquisitions on the innovation capability of core developers in construction companies. Among core developers are those who have deep professional knowledge accumulation and strong ability to digest and innovate external knowledge. The social network analysis method is used to measure the relevant indicators of the core Research and Development (R&D) personnel cooperation network. Bridge Group Co Ltd with Chongqing Beixin Yuchang Expressway Construction Co Ltd are used as examples where the changes in the network structure before and after the merger were investigated using quantitative analysis. These changes were investigated from two perspectives: the individual center cooperation network and the overall cooperation network of core R&D personnel. The results show that the density and centrality indicators of the core developers’ cooperation network have a positive effect on their innovation capability after the merger whereas the structural hole indicators have a negative effect on their innovation. The study broadens the thinking of social networks in the field of technology Mergers and Acquisitions (M&A) and provides directions for enhancing the innovation capability of core developers, as well as serving as a theoretical guide and reference for M&A activities in the construction industry.","PeriodicalId":51753,"journal":{"name":"Journal of Green Building","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135298164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"艺术学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"RELATIONSHIPS BETWEEN EMBODIED, OPERATIONAL, AND LIFE CYCLE CARBON IN PASSIVE HOUSE MULTIFAMILY RESIDENTIAL BUILDINGS","authors":"Robert L. Williams","doi":"10.3992/jgb.18.3.81","DOIUrl":"https://doi.org/10.3992/jgb.18.3.81","url":null,"abstract":"The building sector is responsible for a significant portion of global CO2 emissions and any attempt to meet global climate change mitigation goals requires dramatic reductions in CO2 emissions from building construction and use. Among the many green building certification programs intended to reduce the environmental impact of buildings, the passive house standards are one of the most stringent certifications with respect to reducing operational energy. While there is significant research demonstrating the reductions in operational energy use in passive house and passive house inspired buildings, there is comparatively little research into the embodied energy and embodied carbon emissions associated with these buildings. The aim of this research was to evaluate the relationship between embodied carbon emissions, operational carbon emissions, and overall carbon use intensity in passive house certified residential buildings, using a recently completed, multifamily passive house as a case study. First, the case study building was defined, and a partial life cycle assessment (LCA) was performed to evaluate the embodied and operational carbon emissions associated with this base case. Second, a catalog of alternative wall and roof assemblies were defined and the LCA of the case study was updated for each alternative assembly to assess the impact on the embodied carbon, operational carbon, and overall carbon use intensity. The results of this analysis indicate that the material composition of the exterior envelope assemblies can have significant impact on the overall, cumulative carbon impact of a particular building. Moreover, the results also indicate that there are clear scenarios in which operational energy efficiency should be sacrificed in favor of reducing upfront embodied carbon emissions, particularly when evaluated over critical time spans. Based on these results, this study recommends that green building standards and certifications, including passive house but also USGBC LEED, Living Building Challenge, and others, should place greater emphasis on embodied carbon and holistic carbon accounting in addition to operational efficiency.","PeriodicalId":51753,"journal":{"name":"Journal of Green Building","volume":"380 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135255595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"艺术学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is a lack of uniform definition in this field. This study combines bibliometric and visual analysis of Scopus database publications from 1977 to 2022 to investigate ZEB-related studies. Five topical clusters formed as a result of evaluating the co-occurrence network of the keywords. Finally, the most popular research trends were determined by investigating the overlay network. The scientific knowledge concerning zero energy buildings has been mapped by employing the results of this paper. In addition, they have been utilized to highlight future opportunities and gaps and illustrate the connections between various subject areas.","PeriodicalId":51753,"journal":{"name":"Journal of Green Building","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135297979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"艺术学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study adopted mixed methods by combining qualitative and quantitative methodologies. It began with a systematic literature review, followed by a questionnaire and a comparative analysis to create the primary assessment tool. The study then localized the tool by using the analytical hierarchy process (AHP) to fit the Egyptian context. Finally, the American University Campus in Egypt was selected as a case study to evaluate the tool’s validity. The results revealed that the developed tool is applicable and valid to the built environment. The paper covers the knowledge gap by translating the theoretical basis into a practical tool for creating a national rating system for regenerative development.

These biological prototypes have advantages over expanded polystyrene foam panels, since they do not pollute, they are not flammable, and they are 100% biodegradable. They have been developed growing Pleurotus ostreatus (oyster mushroom) and Lentinula edodes (Shiitake) mycelia on different agricultural substrates inside different types of moulds (up to 21 × 30 cm). As a result, the most suitable combinations of fungi species and agricultural substrates have been determined to grow biological insulating panels. Prototypes obtained were subjected to accelerated ageing tests to evaluate their resistance and changes in durability against water filtration and humidity changes in the event that they are used as insulating panels. Some technological properties have also been determined to evaluate their use as construction materials. The results obtained allow us to claim that biodegradable fungi-based insulating panels are viable to replace polluting foam-based insulating panels for the construction industry.","PeriodicalId":51753,"journal":{"name":"Journal of Green Building","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135297815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"艺术学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
