First, a systematic literature review combined with expert interviews identified 33 housing renovation performance indicators potentially concerned by homeowners. Then, a questionnaire survey was undertaken to collect data on homeowners’ demographic and socioeconomic characteristics and their perceived importance of the indicators. The collected data were analyzed using mean ranking analysis, intraclass correlation coefficient and the Kruskal-Wallis test followed by post-hoc Dunn’s test. The findings reveal that, overall, the mean importance ratings of the performance indicators are consistent across different demographic and socioeconomic subgroups, and “building lifespan” was rated by most groups as the most important indicator. Nevertheless, significant variations in the perceived importance of several indicators existed among different subgroups: men prioritize prestige and status more than women; the elderly place greater importance on both indoor natural daylighting and public lighting; homeowners with secondary education levels show stronger preferences for acoustic comfort than less-educated counterparts; lower-income residents value green and social spaces more; small families are more concerned with residential density; and homeowners with shorter residence care more about fire safety. The underlying reasons for these variations were further examined through in-depth interviews, and practical implications for renovation strategies were identified.

The research provides an overview of how occupants are typically simulated in studies related to multi-domain building performance, with focus on three performance domains: thermal, energy and air quality. Furthermore, it explores different approaches to modelling occupants’ characteristics, presence and adaptive behaviour traits. It discusses aspects of diversity, stochasticity and uncertainty regarding occupants’ actions. Finally, it describes a social practice method that might be utilised in residential building simulation, by creating scenarios of household dynamics for future changing society. The results of this literature review indicate that the current approach to OB modelling for multi-domain building performance is mostly oversimplified. Current OB models typically include a single occupancy scenario and do not account for behavioural changes other than thermal adaptation. However, a new generation of OB models present alternatives to account for the diversity, stochasticity, and uncertainty of occupant behaviour. These create multiple occupancy scenarios with data from national surveys, develop stochastic OB models from previous field studies and employ uncertainty/sensitivity analysis into deterministic models. The review found that the application of social practices might allow the development of future scenarios of living to be integrated into future studies of residential building simulation. This review recommends that future research develops occupant behaviour models through the exploration of datasets, creates diverse scenarios of OB modelling and accounts for changes in occupancy dynamics in future scenarios.</div></div>","PeriodicalId":9273,"journal":{"name":"Building and Environment","volume":"287 ","pages":"Article 113796"},"PeriodicalIF":7.6,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145263852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rather than applying a fixed performance target, such as the widely used 80% satisfaction rate, we propose empirically derived benchmarks based on the distribution of satisfaction rates observed in each survey. Performance levels are then categorized into a 3-star ranking, where 3 stars denotes the highest performance (above the 80th percentile) and 1 star the lowest (below the 30th percentile).

Thermal comfort was the most influential thermal perception variable (loading = 0.65), while age was the most significant individual factor (loading = 0.85).

Our analysis demonstrates that: (1) Intense built-up density and insufficient ecological buffering are primary contributors to urban heat intensification. (2) Regulatory mechanisms differ between heat and cold islands. In heat island zones—especially where space is constrained and blue–green coverage is limited—vegetation functions as the dominant and resilient cooling agent, whereas in cold island formation, large, contiguous water bodies and vegetated buffers play a crucial role by facilitating ventilation and delivering broad, sustained cooling effects. (3) Urban thermal resilience or vulnerability is closely tied to both spatial heterogeneity and connectivity of thermal patterns. Well-connected cold island backbones enable broader and more sustainable citywide cooling, whereas fragmented or isolated patches offer limited mitigation. Conversely, “enclosure-core” spatial configurations—such as the Urban Commercial–Business Area surrounding the Metropolitan Core Area—exacerbate heat entrapment by limiting ventilation and intensifying internal thermal buildup. These findings advance understanding of how urban form, landscape structure, and functional zoning jointly influence heat risk, and provide an operational framework to inform adaptive, differentiated strategies for thermal mitigation and sustainable urban planning.</div></div>","PeriodicalId":9273,"journal":{"name":"Building and Environment","volume":"287 ","pages":"Article 113784"},"PeriodicalIF":7.6,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145219214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these challenges, a multi-task learning model based on a dual-channel graph attention network (GAT) is proposed. The model processes building energy consumption data with strong temporal periodicity and multivariate coupling, and realizes efficient and accurate anomaly detection. The proposed method adopts a feature graph attention layer to model the coupling relationships between the energy consumption of circuits (such as air conditioning, lighting, and power) and environmental parameters, while simultaneously using a temporal graph attention layer to capture periodic patterns like workdays and non-workdays. Based on the prediction error of the temporal convolutional network (TCN) model and the reconstruction error of the variational autoencoder (VAE) model, a dynamic balancing coefficient is designed to achieve adaptive adjustment of the anomaly score to changes in data distribution. The feasibility and efficiency of the proposed novel multi-task model were validated using an energy consumption dataset collected from an office building in Jinan, China. Experimental results show that for anomaly detection of air conditioning, lighting, power, and other circuit energy consumption, the proposed model achieves F1-scores of 0.936, 0.951, 0.905, and 0.892, respectively. Compared with comparative models, the F1-scores are improved by at least 6.1 %, 4.4 %, 3.2 %, and 4.7 %.
