However, existing reinforcement learning (RL) methods face challenges, such as the need for carefully designed reward functions in direct RL and the dual training phases required in imitation learning (IL). To address these issues, this study proposes a Generative Adversarial Soft Actor-Critic (GASAC) framework for controlling residential air conditioning and photovoltaic-battery energy storage systems. This framework eliminates the need for predefined reward functions and achieves optimal control through a single training process. An accurate simulation model was developed and validated using real-world data from a residential building in Japan to evaluate the proposed method’s performance. The results show that the proposed method, without requiring a reward function, increased the time the temperature remained within the comfort range by 11.43 % and reduced electricity costs by 14.05 % compared to baseline methods. Additionally, the training time was reduced by approximately two-thirds compared to direct RL methods. These findings demonstrate the effectiveness of GASAC in achieving optimal temperature control and energy savings while addressing the limitations of traditional RL and IL methods.</div></div>","PeriodicalId":11641,"journal":{"name":"Energy and Buildings","volume":"336 ","pages":"Article 115564"},"PeriodicalIF":6.6,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143644893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Social network analysis is applied to examine the spatial structure of CECI, supplemented by an analysis of carbon emission coordination discrepancies to empirically reveal both quantitative and relational effects of spatial correlations. Results indicate that the GFZ-CUA exhibits a spatial pattern of “high emissions in the north, low in the south, high along the coast, and low inland,” forming a “core-periphery” structure.

Significant disparities are evident in provincial coordination levels.

In order to break through the trust barrier to air-conditioning data, this paper proposes an electronic fault record sharing platform for building air-conditioning based on blockchain technology. The platform utilizes key technologies such as hash algorithm, consensus algorithm, and asymmetric encryption in the blockchain, and chooses the Ethereum network as its deployment platform.

The results of the study show that smart contracts of the Ethereum platform are excellent in handling electronic fault records, which also provides an entry point for the integration of blockchain with building air-conditioning. In addition, the building air-conditioning electronic fault record sharing platform based on blockchain technology also has a low data storage cost, showing broad prospects for its practical application.

The load characteristics of electrical appliances in residential buildings are influenced by various factors, including seasonal variations and user habits. However, there is a notable lack of comparative research on flexible load control across multiple seasons and day types throughout the year, as well as a scarcity of indexes and their grading applications that can comprehensively describe the multi-dimensional building flexibility characteristics. Therefore, this study focuses on typical residential buildings in Cold region and explores the flexible control effects of various strategies in diverse seasonal and day type scenarios. An innovation “digitized-graded” index system is established, grading index values based on flexibility strength, duration, and maximum reduction, thereby providing a comprehensive understanding of demand flexibility from both quantitative and qualitative perspectives. The findings reveal that different control strategies excel in different seasons and distinct evaluation dimensions. Specifically, the strategy of changing the air conditioning temperature set point performs best in summer, while the intermittent start-stop cycles strategy is more suitable for winter. Furthermore, these strategies dominate in <em>Flexibility Strength Index</em> (<em>FSI</em>) and <em>Flexibility Duration Index</em> (<em>FDI</em>), achieving maximum values of 39.3 % and 14 h, respectively, signifying “extremely strong flexibility” and “extremely long-term flexibility”. Adjusting the lighting intensity is optimal in the transition season, followed by summer, and is least effective in winter.

To identify crisis severity, we utilised the mobility data of retail/recreation activities and transit stations, making the results generalisable for any crisis.

However, due to the variability in weather conditions driven by climate change, the actual annual performance of an NZEB may deviate from its optimal design targets. To address this challenge, daily energy management can play a crucial role in maintaining the intended energy balance. A major challenge in daily energy management is ensuring compliance with the annual zero-energy constraint. This paper introduces a novel hierarchical approach for NZEB energy management, integrating medium- and short-term energy management models into a two-layer framework. The upper layer allocates monthly energy consumption to individual loads, while the lower layer translates these allocations into daily boundary conditions. Within this framework, daily load scheduling is optimized to minimize energy costs and reduce residents’ discomfort. A data-driven approach is employed to model both controllable and uncontrollable loads based on residents’ lifestyles and climatic indicators. In particular, thermostatically controllable loads are predicted as a linear function of climatic variables, ensuring adaptive and efficient energy management. The proposed hierarchical approach is implemented in a fully electric, single-family residential NZEB located in Gaithersburg, Maryland, US. The results indicate that a traditional energy management algorithm fails to satisfy the annual zero-energy constraint when annual photovoltaic energy generation decreases to 90% of its current value due to climate change. In contrast, the proposed hierarchical approach successfully maintains the net-zero energy condition even when photovoltaic generation falls below 90% of the current level, while keeping residents’ discomfort within acceptable limits.</div></div>","PeriodicalId":11641,"journal":{"name":"Energy and Buildings","volume":"336 ","pages":"Article 115592"},"PeriodicalIF":6.6,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143637746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 this gap, this review article systematically evaluates the application of ensemble learning models in building energy prediction. Using the PRISMA method, 82 relevant articles published between 2013 and 2024 in the Web of Science database were analyzed. The findings indicate that heterogeneous ensemble models, which integrate diverse algorithms, and homogeneous ensemble models, which utilize multiple data subsets, both hold significant potential for enhancing prediction accuracy. Specifically, heterogeneous models achieved accuracy improvements ranging from 2.59% to 80.10%, while homogeneous models demonstrated more stable improvements of 3.83% to 33.89%. Nonetheless, the integration of multiple base models increases computational complexity, resulting in higher computation times. Despite this drawback, the improved prediction accuracy, robustness, and generalization capabilities of ensemble models justify the additional computational cost. The review identifies key limitations, including the subjective selection of learning algorithms, the lack of systematic methods for evaluating model diversity, and insufficient exploration of combination strategies. Future research should focus on developing objective criteria for algorithm selection, advancing diversity evaluation techniques, analyzing the effects of combination methods, comparing computational efficiency, and validating the robustness and generalizability of ensemble models.
