Trigger my motivations and remove my barriers
Latent class analyses of homeowners’ perception about home energy retrofit
The effectiveness of interventions promoting household energy-efficiency investments depends on the diversity of the target audience. In the context of home energy retrofit, where decision-making is complex and influenced by multiple market and behavioural failures, few studies have rigorously analysed real-world homeowner attitudes and behaviours that enable meaningful policy implications. This study addresses this gap by applying model-based 3-step latent class analyses (LCA) to a sample of 1,011 Dutch homeowners with actual retrofit experience, focusing particularly on various motivations and barriers of home energy retrofit. Five motivation segments and three barrier segments are identified, separately. The motivation segments include balanced motivation homeowners (26.7 %), individual utility maximisers (6.8 %), immediate utility seekers (14.7 %), environmental and immediate utility maximisers (6.3 %), and the environmental-financial sensitive majority (45.4 %). The barrier segments are labelled as balanced financial and feasibility barriers (72.3 %), lack of demand (24.3 %), and prominent non-financial barriers (3.4 %). Both segmentation solutions demonstrate high classification accuracy and meaningful substantive interpretation. Furthermore, the segments for motivations and barriers show only marginal correlations, offering complementary insights. The findings enhance the understanding of homeowner heterogeneity in the energy retrofit market and support the design of more targeted incentives, information, and de-hassling programmes.

Rising energy prices across Europe have increased concerns over energy poverty. Despite significant scholarly focus on financial relief measures instituted by national governments, locally tailored crisis measures have remained overlooked. This study delves into the Dutch context, where part of the government's response to the energy crisis was decentralised, allowing municipalities considerable discretion in experimenting with energy poverty interventions. It compares two strategies: ‘energy coaching’ services – offering advice on sustainable energy practices – and shallow retrofitting by ‘fix teams’ – installing minor energy-saving measures in homes. The impact of these interventions on residential comfort, sustainable behaviour adoption, and (financial concerns regarding) energy bills is assessed through an extensive survey involving treatment and control groups coupled with detailed administrative data on households and dwellings. Results indicate that, on an aggregate level, local interventions significantly enhanced perceived comfort and reduced energy bills among the treatment groups. Comparing individual interventions, notably, more extensive ones such as fix teams and comprehensive energy coaching were significantly more impactful than those involving a single visit, highlighting the importance of continuous engagement. Additionally, we found that energy poverty status significantly amplified the effectiveness of these interventions, thereby stressing the importance of focusing efforts on vulnerable households.

In the context of urban regeneration, community renovation has been a vital approach for improving local living conditions and global sustainable development. Due to the financial burden and uneven regional development, China’s community renovation has gradually shifted from the government-led model to the market-oriented model. However, these projects are subject to various intra- and inter-stakeholder barriers, particularly hidden transaction costs. This study investigates the transaction costs experienced by key stakeholders, including residents, developers, governments, and architects, with a specific focus on the pre-design phase of market-oriented community renovation projects in China. Data on stakeholders’ experienced transaction costs and their origins were collected through semi-structured interviews and questionnaire surveys and were investigated using content analysis and quantitative analysis. Results show that developers bear the most categories of transaction costs. The most significant transaction costs persist in the interactions between developers and governments, including estimating benefits and costs and receiving project approval. Furthermore, negotiating costs are the primary obstructions that hinder stakeholder collaboration. By tracing the origins of these transaction costs, the study proposes measures to optimize the renovation process by reducing transaction costs.

Planning home energy retrofit in a social environment
The role of perceived descriptive and injunctive social norms
In the built environment, improving the energy efficiency of existing building stock through retrofitting is the top pillar to mitigate climate change. Despite the efforts made by local authorities to provide technical and financial supports, the home energy retrofit rate remains low. This study aims to improve the understanding of how homeowners make their energy retrofit plans in a social environment, thereby informing behavioural policy (re)design. Using a sample of inexperienced retrofitters among Dutch homeowners (N = 556), we investigate the relationship between perceived social norms and energy retrofit plans. The results show that homeowners who perceive a positive injunctive norm have an 11.8 percentage point higher probability of making a home energy retrofit plan compared to those with a non-positive perception. Perceived injunctive norms are also significantly associated with the number of planned retrofit measures and aligned with multiple direct barriers and motivations for retrofitting. However, perceived descriptive norms are only associated with the number of planned retrofit measures, and are even correlated with stronger perceived barriers. We conclude by discussing different social influence pathways of descriptive and injunctive norms, as well as the potential of leveraging social norms as a behavioural policy intervention to promote home energy retrofit.

Boosting long-term-oriented thinking to promote home energy retrofit
A choice experiment
In the built environment sector, enhancing energy efficiency through energy retrofitting is a key strategy to mitigate climate change. Despite the efforts made by local municipalities to offer technical and financial support, the rate of home energy retrofit remains low. The decision to undertake home energy retrofit is complex for homeowners. It involves high upfront financial and nonfinancial costs, as well as various benefits over the long term. Substantial costs and ambiguous benefits may prevent homeowners from investing in retrofit measures. Moreover, existing research and policy interventions have rarely accounted for the nonfinancial costs of energy retrofitting. Therefore, this study aims to understand homeowners’ evaluation of nonfinancial transaction costs against financial upfront investment costs. To this end, we design a discrete choice experiment, in which recruited homeowners are presented with a series of decision-making scenarios where they must choose their preferred investment option from two alternatives, alongside the option to maintain the current status quo (no investment). For each retrofit package, we provide information on five attributes: upfront investment cost, time investment, disruption during implementation, energy bill savings, and energy independence. Furthermore, we investigate whether scalable behavioural interventions can be designed to boost homeowners' longtermoriented thinking, thereby increasing their tolerance to short-term costs. A treatment is designed to emphasise long-term financial and nonfinancial benefits of energy retrofitting. We expect that boosting long-term thinking will reduce the negative effects of upfront investment cost, time investment, and disruption on individual utilities, thus increasing homeowners’ preferences for energy retrofit investments.
