Students’ concern for sustainability is an important force in promoting green university initiatives. 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.

ABSTRACT This papers offers a more simple and effective method to simulate indoor and outdoor wind field at the same time, while also exploring the influence of indoor wind field on air conditioning energy consumption. 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. This paper provides important guidance for building researchers and practitioners to better align BIM development with green building development in the future.

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.

ABSTRACT Developing low-carbon cities (LCC) is a strategic measure to mitigate climate change. 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.

ABSTRACT Technology mergers and acquisitions are some of the most important ways to introduce technology into a company. 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.

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.
建筑行业占全球二氧化碳排放的很大一部分，任何实现全球气候变化减缓目标的尝试都需要大幅减少建筑施工和使用中的二氧化碳排放。在众多旨在减少建筑对环境影响的绿色建筑认证项目中，被动式房屋标准是在减少运行能源方面最严格的认证之一。虽然有重要的研究表明被动式房屋和被动式房屋启发建筑的运营能源使用减少，但对这些建筑相关的隐含能源和隐含碳排放的研究相对较少。本研究的目的是评估被动式房屋认证住宅建筑中隐含碳排放、运行碳排放和总体碳使用强度之间的关系，并以最近完工的多户被动式房屋为例进行研究。首先，定义了案例研究构建，并执行了部分生命周期评估(LCA)，以评估与该基本案例相关的实际和操作碳排放。其次，定义了可选墙体和屋顶组件的目录，并更新了案例研究的每个可选组件的LCA，以评估对隐含碳、操作碳和总体碳使用强度的影响。分析结果表明，外护结构组件的材料组成对特定建筑的总体累积碳影响有显著影响。此外，研究结果还表明，在某些情况下，为了减少前期隐含碳排放，应该牺牲运营能源效率，尤其是在关键时间跨度内进行评估时。基于这些结果，本研究建议绿色建筑标准和认证，包括被动式房屋，以及USGBC LEED, Living building Challenge等，除了运营效率外，还应该更加重视隐含碳和整体碳核算。

ABSTRACT The premise of implementing the total amount control plan of building carbon emission should be based on the prediction of the future change trend of building carbon emission. This paper investigates and analyzes peaks of building carbon emission in Ningbo city of China through the Ningbo’s building energy monitoring platform and uses the STIRPAT model to predict the medium and long-term carbon emissions in Ningbo. The peak time and peak value of carbon in the construction field at the city level under the dynamic scenario are simulated based on the Monte Carlo method. The results show that under the benchmark scenario, the carbon emission in the construction field of Ningbo will peak around 2037, with a peak of 22.68 million tons. Through the improvement of building energy-saving laws and regulations, the popularization of green energy-saving buildings, and the establishment of a building energy-saving system, the Ningbo construction department will achieve its carbon emission peak time in 2031 (±2), with a peak of about 15.45 (±1.07) million tons of CO2.

Numerous environmental issues have been addressed as a consequence of rapidly increasing global energy consumption. Building energy consumption has risen considerably in the last few decades. In recent years, the zero energy building (ZEB) concept has attained worldwide attention and is now commonly identified as the future criteria for building design. 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.

ABSTRACT Regenerative development is a paradigm shift in the worldview from conventional sustainability toward rethinking the relationship between the built environment, people, and nature to cope with the consequences of climate change. This article’s goal is to provide an assessment tool that will serve as a guide for applying regenerative development in the built environment. 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. The paper suggests further research to create quantitative indicators for achieving higher reliability.

ABSTRACT This work tackles the development of green biocomposite insulating panels out of fungi mycelia and to replace petroleum-based foam-expanded polystyrene (EPS) panels. 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.
