“…In the online survey, participants were then asked about their plans about retrofitting their homes, recently implemented or ongoing retrofitting projects, the ambitions for energy efficiency upgrades as part of these retrofits, and psychological drivers and barriers of the decisions. The survey used the same questions as a previous survey which had been implemented two times by the same researchers (in 2014 and 2018) in a representative study on energy retrofitting for the Norwegian energy efficiency agency ENOVA Egner, Klöckner, & Pellegrini-Masini, 2021;Klöckner & Nayum, 2016, 2017. Thus, the results from our sample of website users can be compared to two representative samples of house or apartment owners surveyed in 2014 and 2018.…”

Substantial energy efficiency improvement as part of a deep renovation of the privately owned building stock is one of the key pathways to reaching climate and energy transition targets. Meanwhile, it is important to communicate with potential renovators at the right point in time and provide them with targeted information to strengthen their renovation ambition. The European Union recommends using one-stop-shops (OSSs) as a measure to remove unnecessary barriers. OSSs are institutions or websites that provide information and support throughout the whole process from planning to acquisition of funding, implementation, and evaluating. For this paper, we surveyed 437 visitors of two Norwegian websites with OSS characteristics. The visitors were asked about their renovation plans and energy efficiency ambitions. They also rated a range of psychological drivers, facilitators and barriers to including energy upgrades in a renovation project. Their answers were compared to data from representative samples of Norwegian households regarding home renovation in 2014, 2018, and 2023, as well as data from a sample of people who were engaged in renovation projects in 2014. Furthermore, 78 visitors completed a follow-up survey one year later to report the measures they implemented. We found that visitors of the websites are involved in more comprehensive renovation projects and have substantially higher ambitions for the upgrade of energy efficiency compared to the representative samples. They also perceive stronger personal and social norms, as well as have a different profile of facilitators and barriers. The findings suggest that OSSs attract initially motivated people who lack information and are unable to implement their plans alone. Their visit of the websites seems to amplify their ambitions to upgrade energy efficiency of their dwellings.

“…In Norway, individuals get access to retrofitting subsidies in one single scheme from Enova. Past research has indicated that these subsidies are heavily focused on highincome households [45]. In fact, retrofits that are not completed by contractors, but for example by the households themselves, are not eligible for financial support.…”

The realization of sustainable plus energy neighborhoods (SPENs) is key to achieving a carbon neutral built environment, and meeting the objectives of the green deal. Financial schemes have demonstrated effectiveness in driving the energy transition of individual buildings. However, the role of financial schemes in initiating the development of SPENs remains unclear. This study aims to address this research gap by investigating the extent to which existing financial schemes support the technological advancements and stakeholders involved in SPEN realization. The focus is on four European countries: Austria, The Netherlands, Norway, and Spain, where noteworthy SPEN initiatives have been established. This study investigates whether and how financial schemes facilitate SPEN development and address the neighborhood-level dynamics. Our research used a mixed-methods approach comprising a literature review, case studies, and interviews. Our findings shed light on two significant barriers within current schemes. Firstly, the schemes rarely incentivize collective energy sharing and may inadvertently impede individuals’ prosumerism. Secondly, they primarily favor individuals capable of making upfront capital investments, rendering them inaccessible to a large portion of European citizens. By identifying these limitations, our study highlights the need for policy adjustments and innovative financial mechanisms to overcome the barriers hindering SPEN implementation. Moreover, our research contributes to the broader understanding of sustainable urban development and offers insights that extend beyond the examined countries, aiding policymakers and stakeholders in other regions facing similar challenges.

“…Nevertheless, the question of whether the priorities of building renovation are effectively determined for budget distribution according to the target population and purpose of use [11][12][13][14] persists. While problems caused by procedural and systemic issues exist, the most significant issue is that energy poverty in blind spots is not identified through field surveys; furthermore, the same buildings may be repeatedly identified for funding.…”

Enhancing the efficiency of windows is important for improving the energy efficiency of buildings. The Korean government has performed numerous building renovation projects to reduce greenhouse gas emissions and mitigate energy poverty. To reduce the costs and manpower requirements of conventional field surveys, this study presents a deep-learning model to examine the insulation performance of windows using photographs taken in low-income housing. A smartphone application using crowdsourcing was developed for data collection. The insulation performance of windows was determined based on U-value, derived considering the frame-material type, number of panes, and area of windows. An image-labeling tool was designed to identify and annotate window components within photographs. Furthermore, software utilizing open-source computer vision was developed to estimate the window area. After training on a dataset with ResNet and EfficientNet, an accuracy of approximately 80% was achieved. Thus, this study introduces a novel workflow to evaluate the insulation performance of windows, which can support the energy-efficient renovation of low-income housing.
