The inherent qualities of these features are pinpointed together with new photovoltaic attributes that enhance their quality. Recent advancements in photovoltaic technology are described, namely enhanced efficiencies, half-cells, bifacial cells, transparent cells, and tiling ribbons, with their potential for enhanced building integration. The investigation is grounded in principles of building physics and architectural systems analysis. Photovoltaic modules naturally integrate with well-established architectural features, such as atria, curtain walling, multi-skin facades, and solar chimneys. Architectural systems integration serves as the cornerstone for advanced photovoltaic integration and, consequently, the realisation of sustainable architecture. Finally, designers need more information regarding the physical and environmental properties of photovoltaics to better integrate them within architectural fabrics. Thus, enabling critical qualities of energy efficiency in building fabrics to ensure the long-term sustainability of buildings. The article provides a concise overview of new features of BIPV and its potential effects. However, it does not explore specific technologies or architectural solutions in depth. This limitation should be acknowledged, as the study primarily offers a broad perspective rather than detailed technical analysis.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"5 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145168740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The entire cultural complex incorporates a variety of performing art venues such as, the main opera-concert hall (1400 seats), a multipurpose hall (400 seats), choir and orchestra rehearsal rooms, warm up rooms for individual musicians, as well as various ballet and dance rehearsing areas. Due to the topnotch acoustic specifications and the demanding completion schedule the resolution of the acoustic design required proficient, yet realistic, construction methods that could be implemented efficiently in practice. In the present paper the authors provide a detailed description about their pivotal design and construction decisions, which shaped the acoustic outcome as experienced today. The narrative initiates back in 2007 when the authors firm commenced their work with the noise mapping of the -at the time- future building site (upon which the soundproofing of the entire complex was based). The discussion continues with the acoustical challenges faced including also a practical guide, related to acoustics, for developing engineers. The work culminates by emphasizing the crucial role of a qualified acoustic professional, with architectural and engineering expertise, both characteristics required, in order to effectively orchestrate and supervise the construction of such projects. The discourse engages experiences both from the authors 50-years portfolio in similar acoustic projects, as well as from the development of the new cultural complex and their productive collaboration with JV Impregilo-Terna, that brought this magnificent project meticulously into life.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"5 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145011554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most decarbonisation roadmaps and scenario analyses for the sector depend heavily on high-risk technologies such as carbon storage that have not yet been deployed at significant scale, or favour recycling whilst overlooking likely constraints from limited supplies of zero-emissions electricity. This paper therefore provides a first critical review of options to supply construction materials in the UK with realistic expectations about the availability of carbon storage, zero-emissions electricity and zero-emissions transport. The paper focuses on nine key construction materials—concrete, steel, aluminium, structural glass, timber, earth, stone, lime and straw. We conclude that the zero-emissions resource pool includes virgin bio-based materials, limited by the availability of productive land, virgin earth and stone, limited by local geology and transportation, recycled materials, limited by the availability of scrap and emission-free electricity, and reused components, limited by availability and refurbishment potential. This points to the need for a revision to the national construction strategy and a range of entrepreneurial opportunities in delivering the services of construction within a reduced material budget.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"5 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44150-025-00171-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144934714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the rising demand for construction materials, the search for sustainable alternatives has become imperative. This study examines rice husk ash (RHA)-based concrete as a promising alternative to Portland cement, highlighting its significantly lower carbon footprint and improved mechanical properties. Utilizing agricultural by-products such as rice husk, this research investigates the effects of various factors, including concrete age, superplasticizer dosage (ranging from 6.2 to 7.36 kg/m³), fine aggregate content (1819 to 1859 kg/m³), and RHA (55 to 100 kg/m³), on the compressive strength of RHA-based concrete across 186 different mix designs. Five modeling techniques Linear Regression, Non-Linear Regression, Multi-Linear Regression, Artificial Neural Network (ANN), and M5P-Tree were employed to predict compressive strength, ranging from 16 to 104.1 MPa. Model performance was evaluated using metrics including correlation coefficient, Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), Scatter Index (SI), and Objective Function (OBJ). The results indicated that the ANN model outperformed all other techniques, exhibiting superior predictive accuracy and minimal residual error. Sensitivity analysis revealed that age, superplasticizer, fine aggregate, and RHA content were the most influential factors on compressive strength.

A total of 261 concrete mix samples were compiled, each incorporating various combinations of materials such as cement, fly ash, silica fume, GGBS, sand, gravel, water, superplasticizer, and expanding admixtures. Key mix design parameters like the water-to-binder (W/B) and sand-to-binder (S/B) ratios were systematically varied to reflect realistic construction practices. To identify the most influential components and improve model performance, data normalization and sensitivity analysis were performed. The analysis revealed that the W/B ratio was the most critical factor, contributing approximately 31.5% to compressive strength variation. The independent variable ranges in the dataset are as follows: cement (176–873 kg/m3), fly ash (0–262 kg/m3), silica fume (0–57 kg/m3), GGBS (0–228 kg/m3), sand (0–873 kg/m3), water (100–431 kg/m3), gravel (1.5–2001 kg/m3), water to cement ration (W/B) ranged between 0.3–0.85, S/B (0–2), superplasticizer (0–10.9 kg/m3), and expanding admixture (0–58.6 kg/m3). Compressive strength, the dependent variable, ranged from 5.7 MPa to 58.6 MPa. Sensitivity analysis identified W/B as the most influential variable, showing a sensitivity of 31.5% across samples. After testing multiple models, the Full Quadratic (FQ) model emerged as the most accurate based on RMSE, MAE, and OBJ performance criteria. The strength values ranged from 5.7 MPa to 58.6 MPa, encompassing low- to high-strength concrete applications. Among several tested models, the Full Quadratic (FQ) model demonstrated the highest prediction accuracy based on key evaluation metrics (RMSE, MAE, and objective function). This model offers a reliable tool for engineers to estimate compressive strength and optimize mix design without extensive laboratory testing. The proposed approach contributes to reducing construction costs, enhancing design efficiency, and supporting data-driven decision-making in sustainable concrete development.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"5 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144832088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Test results revealed that the proposed strengthening technique is effective enough to enhance the load carrying capacity of the control beam in flexure. The yield and ultimate strengths increased by as much as 45% compared to the control beam in one of the strengthened cases. It was found that the size and thickness of MS flat bar and its location have noticeable influence on the flexure capacity of the strengthened beam. The anchorage failure of royal bolt was the dominant mode of failure, and the effectiveness of the method mainly depends on the performance of the royal bolt anchorage.

Using XLSTAT, a coding-free ML platform integrated into MS Excel, multiple regression algorithms were tested. The Extreme Gradient Boosting (XGBoost) algorithm was selected based on superior predictive accuracy. Two datasets were analyzed: Dataset-1, obtained from published literature, and Dataset-2, collected experimentally at Shalimar Gardens, a UNESCO World Heritage site. Predictions were compared with results from the empirical Federal Transit Administration (FTA) method. XGBoost significantly outperformed the empirical FTA method. For Dataset-1, XGBoost achieved an R² of 0.9092 compared to 0.8618 from FTA. For Dataset-2, XGBoost notably excelled with an R² of 0.9622, whereas the FTA method reached only 0.1907. Additionally, the XGBoost algorithm demonstrated higher accuracy than the previously used GRNN and BPNN models from the literature.

The aim of this study is therefore to clearly identify and classify risks and determine their extent and vulnerability in historic buildings through the development of a holistic risk management strategy in order to contribute to their preventive conservation by proposing improvement plans before they become hazards. Four museum cases were selected as examples of historical buildings in Konya. The potential risks threatening the buildings were determined using data from national databases and the ABC risk analysis method developed by the Canadian Conservation Institute (CCI) and the International Centre for the Study of the Preservation and Restoration of Cultural Property (ICCROM) is used as a risk management approach. In addition, field research, oral interviews, archival and literature research were conducted. By combining all data, a holistic methodology was developed to identify potential risks threatening the buildings, their vulnerability and priority levels, and to determine the current condition of the buildings/museum collections to understand the need for preventive conservation and restoration. As a novel contribution, this study engages in comparative studies by analyzing buildings from different eras, with different materials and construction techniques, and proposes a systematic framework for heritage risk management that combines both qualitative and quantitative approaches. According to the results of the analysis, the average risk of the buildings was categorized as medium and their priority level as low. The analyses carried out were consistent with the results of the on-site observations, so the reliability of this method was considered high.
