Green building construction is essential to meet severe environmental challenges and achieve sustainability, where designers’ practices are crucial to improve the green performance of construction projects. However, multi-level motivations in green design, such as institutional, market, organizational, and individual initiatives, have not been explored in detail. The dynamic interactions of multiple motivations are rarely examined. The present research reports a systematic and dynamic perspective and investigates how multi-level motivations and their interactions act on designers’ green practices. Multi-level motivations towards green design practices are firstly identified through literature analyses and expert interviews. A system dynamics model characterizing the causal structure of a design assessment system is next developed. It involves interrelationships among the organizational, individual, market, and institutional components influencing designers’ green practices. After model validation to ensure credible output, model simulation is conducted to predict behavioral patterns of the model. Monte Carlo simulation is further used to assess the robustness of the model and understand the effects of changes in input parameters on output. The results show that multi-level motivations interact dynamically and have intricate influences on designers’ green practices. The findings indicate the significant role of government policy in encouraging green practices. It is noted that more policy stimuli may not bring more cost-efficient green outcomes. Besides, the development trends of designers’ green practices are relatively consistent with that of green techniques instead of owners’ requirements. This study suggests that the dynamic interactions of multi-level motivations and intricate effects of motivations are crucial for a comprehensive understanding of complex green design practices. Furthermore, a combination of policy considering hybrid effects turns out to be more effective to reinforce green design practices. A 10% synchronous improvement in green policy implementation, organizational strategy, and designers’ ability could enhance designers’ green practices by 40% compared with the base run. The present research contributes to (a) the state of knowledge by offering a systematic and dynamic view to accurately build the dynamic dependent structure of multiple green motivations and enable the thorough assessment of green design and (b) the state of practice by providing guidelines of joint efforts and systems thinking for sustainable development under complex and dynamic conditions.

绿色建筑施工对于应对严峻的环境挑战和实现可持续性至关重要，设计师的实践对于提高建筑项目的绿色绩效至关重要。但是，尚未详细探讨绿色设计的多层次动机，例如机构，市场，组织和个人计划。很少研究多种动机的动态相互作用。本研究报告了系统和动态的观点，并研究了多层次动机及其相互作用如何影响设计师的绿色实践。首先通过文献分析和专家访谈来确定实现绿色设计实践的多层次动机。接下来开发表征设计评估系统因果结构的系统动力学模型。它涉及影响设计师的绿色实践的组织，个人，市场和机构组成部分之间的相互关系。在对模型进行验证以确保获得可靠的输出后，将进行模型仿真以预测模型的行为模式。蒙特卡洛模拟还用于评估模型的鲁棒性，并了解输入参数变化对输出的影响。结果表明，多层次动机动态相互作用，并且对设计师的绿色实践产生了复杂的影响。调查结果表明政府政策在鼓励绿色实践方面的重要作用。需要注意的是，更多的政策刺激可能不会带来更具成本效益的绿色结果。除了，设计师的绿色实践的发展趋势与绿色技术的发展趋势相对一致，而不是业主的要求。这项研究表明，多层次动机的动态相互作用和动机的错综复杂的作用对于全面理解复杂的绿色设计实践至关重要。此外，结合了混合效应的政策组合被证明在加强绿色设计实践方面更为有效。与基本运行相比，绿色政策实施，组织战略和设计人员能力的10％同步改进可以使设计人员的绿色实践提高40％。
