As college students bear little energy cost of public buildings on campus, information intervention is more feasible than economic intervention to augment the energy-saving intention of college students. College students are sensitive to environmental information; thus, building energy consumption information, which reflects the energy consumption levels of the environment where students live, may be effective to promote the energy-saving intention of college students. However, the changeable cognitive structure of college students makes it difficult to predict the cognitive results of building energy consumption information. Based on social cognitive theory and theory of planned behavior, this paper reveals the impacts of building energy consumption information on energy-saving intentions of college students from the perspective of perceived value and personal norms. The conclusions are: (1) The impacts are positive and indirect; (2) the impacts are realized through the path “perceived benefit—perceived value—intention” and “perceived benefit & risk—personal norm—intention”; (3) the perceived value and personal norm independently affect energy-saving intention; and (4) the effect of perceived benefits is the most obvious. Based on the above results, we put forward a series of policy suggestions, with the aim to enhance the positive effect of building energy consumption information on college students.

Prefabricated buildings (PBs) are vigorously promoted for their many advantages. However, obvious regional differences exist in the development of PBs in China, and underdeveloped areas significantly lag behind other areas. Regional “tactics” have a more direct effect on the development of PBs than national “strategies”. A targeted analysis of PB policies in underdeveloped areas in China is lacking in current research. Therefore, the aim of this study was to construct a comprehensive policy framework to help underdeveloped areas improve PB policies to develop PBs. In this study, we constructed a three-dimensional policy framework based on the content analysis method and policy instrument theory. Through a comparative analysis of 137 PB policies in three representative regions, 547 policy content codes were obtained, and reliability and validity tests were completed. The results indicate that (1) underdeveloped areas should focus on improving the number of policies rather than the accuracy in the early stages of development of PBs; (2) underdeveloped areas should focus on mandatory policy instruments (MPIs) supplemented by incentive policy instruments (IPIs) and social policy instruments (SPIs) rather than a balanced use of various policy instruments; and (3) underdeveloped areas should adjust the policy layout of the whole life cycle, and stakeholders should pay attention to the construction willingness of developers and the demands of consumers and seek policy support in the operation and maintenance stages, as well as during the demolition and recovery stages. In this study, we systematically analyzed the focus of PB policies for different stages and stakeholders and proposed an application strategy of policy instruments, contributing to the improvement of the PB policy system and the narrowing of regional development gaps with respect to PBs.

Urban utility tunnels (UUTs) have become an important infrastructure for sustainable urban development. However, numerous uncertainties brought by the complex stakeholder groups seriously hinder sustainable operation and maintenance (O&M) of UUT projects, which make it necessary to plan the development of UUT projects in advance. Previous studies mostly identified and analyzed the influencing factors from the partial life cycle perspective and neglected the limitations of exploring the complex whole life cycle factors from one single perspective. This paper comprehensively considered the perspectives of stakeholder roles and the whole UUT project life cycle and proposed a factor identification and analysis framework. In the factor identification section: (a) literature surveys were conducted to identify all influencing factors of stakeholders at each stage; and (b) 21 types of factors were identified through semi-structured interviews. In the factor analysis section: (a) the hierarchical structure of the factors was analyzed by introducing the Decision-Making Trial and Evaluation Laboratory (DEMATEL) approach and Interpretative Structural Model (ISM); (b) the various factors were divided into linkage, dependent, autonomous, and driving factors to clarify their influence degrees; and (c) the core influencing factor was determined based on the above analysis results and the two perspectives. The results indicated that (1) the pricing and charging mechanism is the decisive factor affecting the sustainable O&M of UUTs, the government should focus on establishing a standardized and transparent pricing and charging mechanism; (2) policy support to encourage social capital and user participation should be actively explored; and (3) UUT development must rely on the strong promotion of the government, and the needs of all stakeholders throughout the life cycle should be paid attention to. This study can provide useful insights for guaranteeing the sustainable O&M of UUTs in China and similar regions.
