While thermal analysis methods for energy piles have been extensively studied, no previous research has specifically focused on long segmental quadratic concrete driven energy piles. Additionally, previous studies have applied fixed temperature boundary condition at the pile/ground top surface, which is the incorrect representation of the interface between the pile/ground surface and the building at the top. The main contributions of the present study are the development of semi-empirical G-function design charts, using a heat flux boundary at the pile/ground surface, and covering a wider range of energy pile lengths and soil and concrete material properties. A 3D finite element model was validated with thermal response tests on quadratic energy piles, and later employed to produce G-functions, applicable to longer segmental quadratic piles. The G-function design charts simplify the thermal design for practicing engineers and require minimum computational effort for long-term analysis. The results reveal that the pile/ground surface boundary conditions can affect long-term thermal performance by approximately 20%, though their influence is negligible in short-term analyses. The developed G-functions were employed to investigate two case studies in terms of ground temperature prediction for a quadratic driven energy pile under apartment blocks located in Oslo and Røros, respectively. The case studies showed that quadratic driven energy piles can cover 60%, and 48% of the heating demand for well insulated buildings in Oslo and Røros, during the design life of the buildings without adversely affecting the ground temperature.</div></div>","PeriodicalId":11641,"journal":{"name":"Energy and Buildings","volume":"337 ","pages":"Article 115652"},"PeriodicalIF":6.6,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143747379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding some of the mechanisms behind this gap, such as, the energy-related decisions and/or shared heating practices among occupants, could foster effective strategies for promoting energy efficiency. However, such mechanisms are not yet well identified, especially in residential contexts and low-energy buildings, where the relative impact of occupants’ behavior is predominant. Aiming to contribute to tackling this knowledge gap, this article presents the results of a sequential mixed-method approach, combining quantitative and qualitative methods to study the energy-related practices of six occupants in five households of a multi-story low-energy household block located in Denmark. The households are monitored with sensors measuring heating use, room temperature, and heating setpoint temperature, enabling to capture human-building interactions at a high resolution. The quantitative analyses (data analyses) showed substantial differences in heating behavior and practices and thermal comfort preferences across households and over the seasons (from 90 to 301 heating days a year). Nevertheless, the qualitative analysis (semi-structured interviews) indicates shared practices regarding the use of the feedback display installed in each dwelling. This suggests that despite individual differences in preferences and habits, households living in the same building still share heating practices. The findings underpin the importance of the building managers’ support and trust in improving feedback implementation and ensuring heating practices to support building energy efficiency.</div></div>","PeriodicalId":11641,"journal":{"name":"Energy and Buildings","volume":"337 ","pages":"Article 115650"},"PeriodicalIF":6.6,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143760408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research innovatively proposes a dialectical system framework for building occupant energy behavior, constructing the relationships between elements within the system from three dimensions: conceptual, methodological, and value, and examining the antagonism and unity between different subsystems. In the conceptual dimension, building occupant energy behavior is deconstructed into two core components, building and occupant energy behavior, which are further divided into multiple subsystems with detailed elaboration on their scope and content. In the methodological dimension, this research summarizes the strengths and limitations of existing quantitative and qualitative methods, discusses the trade-offs among different methods, and integrates these methodologies within the conceptual framework to analyze their applications in the context of building and occupant energy behavior. In the value dimension, it identifies the needs of various stakeholders and analyzes the multi-dimensional value that building occupant energy behavior research provides to them. Based on this framework, this research identifies existing research gaps and proposes future research directions, aiming to promote further exploration in the field and providing researchers with a novel dialectical systemic framework to understand the complexity of occupant behavior.</div></div>","PeriodicalId":11641,"journal":{"name":"Energy and Buildings","volume":"337 ","pages":"Article 115649"},"PeriodicalIF":6.6,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143760508","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}

The combined implementation of non-invasive mitigation strategies (such as internal shading, free cooling by nighttime ventilation) led to a reduction in the Intensity of Thermal Discomfort (ITD) by up to 95% in the critical zones.

Additionally, the pertinent knowledge of hydrodynamics, particularly the description of vapor transport, is summarized. Subsequently, current models are reviewed from the perspective of the interplay between the liquid–vapor transition and vapor transport processes. The descriptions and limitations of phase transition processes in these models are then discussed. According to these analyses, a key distinction in the description of the liquid–vapor transition lies in the presence or absence of evaporative mass flux.

The use of these formulas negates external environmental influences on the transition process, including boundary layer effects. Hertz-Knudsen-type formulas capture the essence of the process, although they make overly strict assumptions about surface geometry.

However, the pace of renovation in the European building stock remains relatively slow. The objective of this study is to enhance our understanding of the renovation status of the French building stock by cross-analysing multiple databases. In order to assess the levels of renovation, a methodology is proposed which combines Energy Performance Certificate (EPC) data with Danube, an archetypal architectural database. By mapping the Danube archetypes to the EPC geospatial data, an examination of the renovation status across different buildings can be conducted, taking into account factors such as construction period, building usage, urban form, and geographical location. The methodology employed entails the establishment of a correspondence between the aforementioned databases, the calculation of U-values for building envelope components of the Danube database, and the conduct of a comparative analysis of their thermal performances with the EPC referential. The findings of this study reveal a complex pattern of renovation rates across different construction periods and housing types. Notably, buildings constructed after the Second World War exhibit the highest rates of renovation. Additionally, individual dwellings undergo more extensive roof renovations than collective housing.
