Synergistic development of green building market under government guidance: A case study of Tianjin, China

Under the restriction of carbon neutral and carbon peak, the development of green building has become the strategic demand of most countries in the world. Despite the rapid development of green building in China, there are still some problems, such as insufficient market development force under the government's leadership, emphasizing design and neglecting operation. In order to realize high-quality synergistic development of green building market, this paper constructs a new synergistic development framework of green building market, establishes a tripartite evolutionary game model including local governments, developers and consumers, uses the analysis tool of evolutionary game theory and synergistic theory to explore the unilateral ESS and the system ESS of green building market. In order to verify the model, this paper adopts a case study method, takes a residential building project in Tianjin, China which has awarded a three-star mark in green building design evaluation as an example for numerical simulation, discusses the influence of government guidance on the system evolution trajectory, demonstrates the interactive process of stakeholders' behavior, and finds out the key factors affecting the system equilibrium strategy. The result shows that (1) the means of government guidance will affect the speed and result of system evolution; (2) the strategy of stakeholders depends on the comparison of costs and benefits; (3) the probability of ideal events is positively correlated with the economic benefits and negatively correlated with incremental cost of green building. This study can provide theoretical guidance for local governments, developers and consumers to make scientific decisions, and provide practical enlightenment for government to play a more active role in green building market.

BIM applications in sustainable construction: scientometric and state-of-the-art review

The construction sector is notorious for being unsustainable and disintegrated industry while, it is crucial to provide a lens towards sustainable construction from the digital innovation and integration perspective. Although a considerable amount of research has been focused on how building information modeling (BIM) helps improve sustainable construction; there are still a limited number of studies that have investigated the BIM process in sustainability fields. This study aims to identify all common domains of BIM and sustainability applications and reveals the academic and practice gaps in the construction industry. Through employing the scientometric analysis method, a collective number of 188 journal articles were gathered and analyzed. The thematic analysis was then applied and five common domains of BIM and sustainability on lifecycle assessment, green buildings criteria, energy analysis, environmental assessments and design, construction and project management were eventually identified. The current study identifies the research confusion, neglect and application gaps across all five identified domains and provides researchers with a deep understanding of BIM in the sustainability and future directions for further research.

Research on Village Planning and Rural Architectural Design Based on Discrete Dynamic Modeling Technology

With the advent of the era of big data, the combination of science and technology and urban and rural planning has become the focus of many countries. The improvement of village planning and the redesign of rural buildings can promote the rapid development of villages and strengthen rural cohesion. Based on the above situation, this paper proposes a dynamic programming algorithm combined with discrete dynamic modeling technology to improve rural planning. Firstly, the dynamic programming algorithm is used to reconstruct the village layout and optimize the original village model. The dynamic monitoring technology is used to update the dynamic data in real time to provide specific information for the follow-up rural architectural design. Secondly, the dynamic modeling technology is used to build the building model, which can calculate the building location and building angle of the village. In order to further improve village development, we also put forward the concept of green building design. The performance of traditional modeling technology and discrete dynamic modeling technology in the green building design model is compared. The results show that the discrete dynamic modeling technology can improve the overall performance of rural buildings and improve the operation efficiency of the system in the batch design of green buildings. The village layout improved by dynamic planning reduces the specific travel distance of villagers and provides effective help for rural construction and economic development. Compared with traditional modeling technology, dynamic modeling technology has a shorter workflow and less time. Discrete dynamic modeling technology can realize dynamic batch architecture design and has higher applicability than traditional algorithms.

How to minimize the embodied environmental impact of green building envelope? An automatic optimization method

Building envelopes are a key element of green building design due to the immense amount of building energy and consumables. However, the quantitative evaluation of the embodied environmental impact of the envelope structure in green buildings is limited. This study aims to minimize the embodied environmental impact of the envelope structure. First, the types of embodied environmental impacts are classified into 12 categories (global warming, ozone depletion, eutrophication, smog, acidification, criteria air pollutants, indoor air quality, human health, ecotoxicity, habitat alteration, water intake, and fossil fuel combustion) using the causal network method and the equivalent factor method. Second, a quantitative model for evaluating the embodied environmental impact is developed based on the distance-to-target approach. Third, a green building in Jiangsu Province, China, is used as a case to form a green building envelope technology checklist by considering building envelope design principles. Building for Environment and Economic Sustainability (BEES) software is used to calculate the life cycle environmental impact inventory and embodied environmental impact. Furthermore, C# programming language is used to select 25 green building envelope packages with minimal environmental impact. This study offers an indepth understanding of the embodied environmental impact of green building envelope. The developed model not only calculates the accurate embodied environmental impact of green building but also provides an effective platform for identifying and determining the best building envelope structure to minimize the environmental impact of green buildings.

Value Creation Assessment Tool for Green Buildings: Development and Implementation

Green buildings are predestined for the sustainability of arid regions. Presently, professionals working on building construction projects have no assessment tool that integrates value creation and associated risks in the development phase to enhance the value created by green buildings. The present study developed and tested a value creation assessment tool to evaluate the total added value and associated risks that can impact the created value by green building design. The tool consisting of 51 performance value drivers and 35 risk factors was tested on three different buildings in Saudi Arabia. Using a questionnaire survey, each of these projects was scored by its value engineering team and weighted mean scores (Wms) as percentages were calculated. The study revealed that the environmental driver was given less importance in the design process with Wms of less than 60% for all three types of buildings, while the functional driver was given higher importance with Wms of 80% or more. All the buildings showed moderate financial risks ranging between 40 and 50% and a higher potential of management risks with scores around 60% or higher. A wide variation between 20 and 60% was observed for operational risks. The study also found that large‐scale buildings are less threatened by financial risks. The developed tool will facilitate the stakeholders and designers in identifying project development contextual issues and provide opportunities to optimise the design and operations to enhance performance efficiency and obtain more value from investment in GB assets during the early stages of development in Saudi Arabia and elsewhere.

Use of industrial waste burnt residue to develop sustainable brick

An increase in environmental concern has occurred from the accumulation of mismanaged industrial burned residue, particularly in developing countries. Recycling these wastes as a sustainable building material seems to be a potential solution not only to the pollution problem, but also to the cost of green building design. In order to develop sustainable construction materials, industrial and incinerated leftover materials are being used. The goal of this research is to find out more about the probability of replacing natural soil in brick production with burned industrial waste, such as Cupola Slag and fly ash. This study is based on various mix proportions for making bricks keeping constant cement by 10 %. Brick mixture was prepared with cupola slag and fly ash for various proportions. From the five distinct mixes with variable CS from 80% to 60%, the M1 mix with 80 % CS, 10% FA, 10% Cement had the highest compressive strength 4.5 N/mm2. Compressive strength for burnt clay bricks is 3.5 N/mm2 which is less than cupola slag bricks, while the brick mix M5 (60 CS: 30 FA: 10 cement) had the lowest water absorption and density 6.53 % and 1350.57 kg/m3. This study reveals that used of cupola slag and fly ah in combination gives satisfactory results to be used in making sustainable bricks.

A Solar Water-Heating Smart Window by Integration of the Water Flow System and the Electrochromic Window Based on Reversible Metal Electrodeposition.

Various smart windows with dynamic modulation of the light transmittance have been developed rapidly in recent years. However, current design of the smart windows can only modulate the indoor solar irradiation instead of effectively utilize them. Here, a solar water‐heating (SWH) smart window is proposed by the integration of the traditional electrochromic window and the water flow system, which can not only provide dynamic daylight modulation but also harvest the solar energy and store them by heating water. In the SWH window, the reversible metal electrodeposition (RME) not only provides daylight modulation but also provides metal layer working as a flat‐plate solar collector for energy harvesting. Compared with traditional electrochromic windows, the SWH window with a water flow system can more effectively modulate the indoor temperature, owing to the significantly enhanced tunability of the thermal irradiation from the window. Compared with water‐flow windows, the RME provide a metallic layer for efficient light harvesting, up to 42% solar energy can be effectively harvested and stored as hot water. Such an SWH smart window is promising to reduce the heating, lighting, and air conditioning energy consumption, which may bring new insights in the design of the next‐generation green buildings.

Stakeholders’ perspectives on BIM and LCA for green buildings

There is growing concern about the environmental impacts of buildings on climate change. In this regard, the concept of integrating building technologies and environmental assessment methods, namely Building Information Modelling (BIM) and Life Cycle Assessment (LCA), has arisen as an innovative approach to improve building environmental assessment at the design phase. Recent studies made attempts to develop theoretical frameworks for BIM and LCA integration focusing on the technical aspects and the challenges of this integration. However, the stakeholders' perspectives on this integration of BIM and LCA for building environmental assessment have been overlooked. Therefore, there is a pressing need to understand the stakeholders' perspectives on BIM and LCA and their value for improving green building design and assessment. This study contributes to the existing knowledge on the potential implementation of an integrated BIM-LCA framework for building environmental assessment. To this end, this study investigates (1) the current applications of BIM and LCA in green buildings from the stakeholders' perspectives and (2) the stakeholders' level of awareness and agreement on the significance of BIM and LCA for green building design and assessment. In order to achieve this goal, a national survey was conducted among multiple stakeholders in the New Zealand building industry. The results indicate that BIM and LCA applications for green buildings are still immature. A statistically significant correlation is observed between the importance of BIM and LCA applications for green buildings. The stakeholders perceive BIM and LCA potentials and their integration positively. However, the current practices and applications of BIM and LCA do not align with the stakeholders’ perceptions. Massive efforts are still required for a wide implementation of BIM and LCA and their potential integration for green buildings.
