This paper presents a systematic and critical review of 54 studies focusing on daylight enhancement strategies in historic buildings, published between 2000 and 2025. Following the PRISMA scoping review method, this review investigates intervention challenges according to three primary constraints: regulatory and conservation limitations, material and structural constraints, and climate-responsive requirements. By mapping currently employed daylighting techniques in historic buildings and critically assessing their underlying assumptions, this study aims to bridge the gap between performance-driven daylighting research and cultural heritage preservation principles. The findings are intended to promote multidisciplinary discourse and serve as a basis for creating contextually acceptable, ethically responsible, and technically feasible daylighting recommendations for historic buildings.","source":"DOAJ","year":2026,"language":"","subjects":["Details in building design and construction.

This study bridges this gap by developing and validating a novel, socio-technical retrofit model for Zero-Energy Housing (ZEH) tailored to the specific context of Ghazni Province. The novelty of this work lies in the rigorous localization of global ZEH principles to AFG’s low-income, post-conflict context and the pioneering integration of a full lifecycle carbon assessment within this localized framework. Employing a mixed-methods approach, the research integrates computational energy simulation, embodied carbon assessment, and primary socio-technical data from household surveys and expert interviews. This integration allows for a holistic diagnosis of the existing housing stock, identifying profound inefficiencies such as inadequate insulation, non-energy-efficient fenestration, and reliance on carbon-intensive materials. In response, a localized four-pillar (Awareness, Building Envelope, Clean Energy, Policy) design framework is proposed and rigorously simulated. Results for this context demonstrate a 33% reduction in Energy Use Intensity (EUI), a 64.4% decrease in heating demand, and a 27.9% reduction in cooling demand. Furthermore, the model achieves a 35% reduction in embodied carbon and, through integrated rooftop solar photovoltaics (PVs), meets 102% of annual energy demand, realizing a net-zero operational energy balance. An initial economic assessment indicates a payback period of 13-15 years for the integrated retrofit package, underscoring the critical role of financial mechanisms for feasibility. This research provides an evidence-based, integrated blueprint that advances global ZEH principles by grounding them in local socio-economic and climatic realities. It offers actionable recommendations for policymakers, architects, and builders, focusing on building code reform, lifecycle carbon mitigation, and community engagement, thereby establishing a foundational pathway for sustainable housing transition in AFG and similar regions.","source":"DOAJ","year":2026,"language":"","subjects":["Details in building design and construction.

Therefore, it is essential to analyze the competitiveness of a concentrated solar power (CSP) plant in La Joya, Arequipa, Peru, in comparison with the local electricity provider (SEAL) tariff and the LCOE target set for 2030 by the U.S. Department of Energy's Solar Energy Technologies Office (SETO). This study focuses on assessing the feasibility of five CSP plant configurations with different capacities (19.9 MWe,50 MWe, 100 MWe, 150 MWe, and 200 MWe) in Arequipa by calculating the LCOE with varying durations of thermal energy storage (TES) from 0 to 18 hours. Additionally, the LCOE of the Gemasolar plant (19.9 MWe) in Seville, Spain, is analyzed and projected in Arequipa using economies of scale. The projected LCOEs of the CSP plants are compared with SETO’s target (5 ¢/kWh) and SEAL’s tariff (20 ¢/kWh). Finally, the LCOE is broken down into its main components to identify the most significant costs. The methodology was developed in three stages: (1) collection of technical, economic, and geographical parameters of Gemasolar along with climate and radiation data from Arequipa; (2) simulations in the System Advisor Model (SAM) software to optimize CSP plant design, considering the number and arrangement of heliostats, as well as the dimensions of the tower and receiver; and (3) processing of results in Excel to calculate the LCOE for each CSP configuration and the generation of contour maps in MATLAB to compare LCOE, TES, design power, and relative percentages against SETO targets, SEAL tariffs, and the Gemasolar plant. A total of 152 simulations were conducted in SAM to optimize the design. The results show that the LCOE of the analyzed CSP plants is between 120% and 260% above the SETO target, with values ranging from 11 to 18 ¢/kWh. However, the projected CSP LCOE is between 10% and 61% lower than SEAL’s rate, with values between 12.2 and 18 ¢/kWh. The four main components account for 78.6% of the total LCOE, with thermal storage being the most significant (37.5%), followed by heliostats (21.89%), the receiver (11.54%), and the power block (8.23%). The average annual LCOE reduction for CSP technology is approximately 1.69%. In conclusion, none of the projected CSP configurations achieve the SETO target, and even with a reduction in the main components, the LCOE would remain between 86.28% and 226.28% above this target. Thermal storage is the component with the greatest cost reduction potential, potentially lowering the LCOE by 20%. Nevertheless, all the projected CSP configurations are attractive for public or private investment, as they offer electricity at a lower cost than the local SEAL provider. Although Peru has photovoltaic plants that harness solar radiation, the LCOE of the analyzed CSPs is 219.2% higher. However, CSPs offer a significant advantage in terms of capacity factors, reaching up to 65% compared to 33% for photovoltaic plants.","source":"DOAJ","year":2025,"language":"","subjects":["Details in building design and construction.

Despite their importance, balconies are often designed repetitively across floors without accounting for the variation in environmental conditions at different elevations. Therefore, this study aims to optimize the envelope design of residential bedrooms with balconies to improve visual and thermal comfort, and energy performance across three representative floor positions: lower (3 m), middle (18 m), and upper (33 m), considering the surrounding context in hot-humid tropical climate of Dhaka, Bangladesh. The proposed research framework combines parametric-based multi-objective optimization using the NSGA-II algorithm with multi-criteria decision-making through K-means clustering and Sobol sensitivity analysis. Design variables are grouped into three categories: envelope geometry, balcony geometry, and material types. The four performance objectives include maximizing spatial daylight autonomy (sDA300/50%), spatial glare autonomy (sGA40%/5%), and thermal comfort percentage (TCP), while minimizing energy use intensity (EUI). Results reveal that optimal solutions vary significantly by floor. Lower floors benefit from wider glazed openings and higher parapets to control reflected glare, while middle floors achieve balanced performance with smaller openings and moderate balcony features. Upper floors prioritize deeper shading and reflective materials to manage intense solar exposure. It also challenges conventional recommendations by identifying parapet height, not glazed door width, as the key variable for visual comfort on lower and middle floors. In contrast, glazed door width is more influential on upper floors through Sobol sensitivity analysis. In addition to this, second-order interactions, particularly among balcony-related parameters, were strongest on lower floors, moderate on upper, and minimal on middle floors. This study contributes to the current knowledge on climate-responsive high-rise design by demonstrating the importance of floor-specific strategies for a hot-humid tropical context. The proposed approach aids designers in making informed decisions not only during early design phases but also for renovation and code development in a similar climatic context.","source":"DOAJ","year":2025,"language":"","subjects":["Details in building design and construction.

Most existing methods rely on segmentation-based models that assume clear semantic boundaries of roofs, but these approaches struggle in off- nadir images, where the roof and footprint are significantly displaced, and facade pixels are fused with the roof boundary. With the increasing availability of open vector map annotations, e.g., OpenStreetMap, utilizing historical labels for off-nadir image annotation has become viable because remote sensing images are georeferenced once captured. However, these historical labels commonly suffer from significant positional discrepancies with new images and only have one annotation (roof or footprint), which fails to describe the correct structures of a building. To address these discrepancies, we first introduce a concept of an alignment token, which encodes the correction vector to guide the label correction. Based on this concept, we then propose Drag OpenStreetMap Labels (DragOSM), a novel model designed to align dislocated historical labels with roofs and footprints. Specifically, DragOSM formulates the label alignment as an interactive denoising process, modeling the positional discrepancy as a Gaussian distribution. During training, it learns to correct these errors by simulating misalignment with random Gaussian perturbations; during inference, it iteratively refines the positions of input labels. To validate our method, we further present a new dataset, Repairing Buildings in OSM (ReBO), comprising 179,265 buildings with both OpenStreetMap and manually corrected annotations across 5,473 images from 41 cities. Experimental results on ReBO demonstrate the effectiveness of DragOSM.

However, traditional evacuation simulation relies heavily on refined modeling with extensive parameters, making it challenging to adopt such methods in a rapid iteration process in early design stages. Thus, this study proposes DiffEvac, a novel method to learn building evacuation patterns based on Generative Models (GMs), for efficient evacuation simulation and enhanced safety design. Initially, a dataset of 399 diverse functional layouts and corresponding evacuation heatmaps of buildings was established. Then, a decoupled feature representation is proposed to embed physical features like layouts and occupant density for GMs. Finally, a diffusion model based on image prompts is proposed to learn evacuation patterns from simulated evacuation heatmaps. Compared to existing research using Conditional GANs with RGB representation, DiffEvac achieves up to a 37.6% improvement in SSIM, 142% in PSNR, and delivers results 16 times faster, thereby cutting simulation time to 2 minutes. Case studies further demonstrate that the proposed method not only significantly enhances the rapid design iteration and adjustment process with efficient evacuation simulation but also offers new insights and technical pathways for future safety optimization in intelligent building design. The research implication is that the approach lowers the modeling burden, enables large-scale what-if exploration, and facilitates coupling with multi-objective design tools.","source":"arXiv","year":2025,"language":"en","subjects":["cs.LG"],"doi":"10.1016/j.jobe.2025.114644","url":"https://arxiv.org/abs/2510.19623","pdf_url":"https://arxiv.org/pdf/2510.19623","is_open_access":true,"published_at":"2025-10-22T14:20:00Z","score":69},{"id":"ss_a7c8fb6b3ee573fb49d0d9bdf4dedcc61193e0c9","title":"DEFECTS AND ACCIDENTS OF THIN-WALLED SLOPING REINFORCED CONCRETE SHELLS","authors":[{"name":"B.

Although it is impossible to completely eliminate accidents, it is crucial to ensure that when design loads are exceeded, failures remain localized and do not grow into progressive or cascading collapses. When analyzing the causes of structural failures, attention must be given to errors made during the design, construction, and operational stages. Notable example of a failure caused by design shortcomings is the collapse of the roof of the Yasenevo water park in Moscow, RF. Article presents verification calculations of the reinforced-concrete shell that revealed insufficient strength, stiffness, and stability. Primary cause was an unsuccessful design choice - selecting a shell geometry with excessively flat areas near the support contour, which significantly reduced its load-bearing capacity. Special emphasis is placed on the survivability of buildings and structures, including their ability to maintain structural integrity under unexpected or extreme loads. Paper examines factors that contributed to the shell collapse: total deflections, excessive flatness, inadequate rigidity, actual operational loads, and real physical-mechanical properties of materials. Recommendations are provided for the design of shallow reinforced-concrete shells, highlighting critical aspects that require the designer’s attention to avoid similar failures. Modern calculation program STARK_ES3.1 is used for analyzing shallow reinforced-concrete surfaces, with geometric parameters and material properties presented in detail. Expanded literature review is included, focusing on creep, long-term performance, and durability of shallow reinforced-concrete shells.","source":"Semantic Scholar","year":2025,"language":"en","subjects":null,"doi":"10.51488/1680-080x/2025.4-08","url":"https://www.semanticscholar.org/paper/a7c8fb6b3ee573fb49d0d9bdf4dedcc61193e0c9","is_open_access":true,"published_at":"","score":69},{"id":"doaj_10.15627/jd.2024.4","title":"A Multi-objective Optimization of Window and Light Shelf Design in Office Buildings to Improve Occupants’ Thermal and Visual Comfort","authors":[{"name":"Fatemeh Rezaei"},{"name":"Hamed Sangin"},{"name":"Milad Heiranipour"},{"name":"Shady Attia"}],"abstract":"In office buildings, an efficient design of windows and using light shelves as a passive design strategy significantly influence the thermal and visual comfort of occupants while enhancing the productivity and health of users.

Afterward, the Honeybee energy and daylight plugin was employed for simulating thermal and visual conditions, and finally, multi-objective optimization was conducted with the Octopus plugin. This plugin can determine the best solution as a compromise decision for maximizing occupants' comfort. In this paper, an office building in Tehran has been chosen as a case study.

In Dhaka, a tropical city, the construction of major arterial roads connecting the northern and southern regions of the city has led to the emergence of numerous commercial buildings along these roads, predominantly facing in east or west directions. This research investigated the efficiency of different existing fenestration types (glass curtain walls, glass windows with horizontal and vertical louvres, overhangs, vertical fins, and egg crate shading) of west-facing office buildings in Dhaka in terms of daylight, thermal comfort and energy efficiency, and explore strategies to enhance existing performance. From the field survey, a 'case office building' was selected, and simulations were carried out with the six different fenestrations, as mentioned above, while keeping other aspects constant as found during the survey, e.g., floor plan, equipment and number of occupants. In this research, the simulation process encompasses daylighting simulation, energy simulation, and multi-objective optimisation. The study utilised a case model created with Rhinoceros and ClimateStudio, while performance metric optimisation was achieved using Grasshopper and Octopus. Multi-objective optimisation techniques were employed to improve the shading configurations. The TT toolbox facilitated data exportation and Design Explorer assisted in data visualisation. The window with egg crate shading was found to be the most effective fenestration type among the studied shading configurations. Further parametric simulation was conducted to develop an optimised egg crate shading design configuration. It was found that egg crate shading with a 1.0 m depth provided optimum daylight and solar heat gain inside the office building among the studied configurations in the context of Dhaka. A comparison was also made between the optimised egg crate option and a customised egg crate with some detailing (popularly known as brise soleil). Brise soleil showed better performance with 12.2% higher sDA and 98 lux additional average illuminance compared to the previous optimum one. The findings underscore the significance of employing optimisation methodology to devise shading configurations while also revealing substantial opportunities to enhance performance further by tailoring details on the optimised design recommended from simulation analysis.","source":"DOAJ","year":2024,"language":"","subjects":["Details in building design and construction.

Indonesia terkena dampak yang sangat besar dalam pertumbuhan virus covid-19 ini. Salah satunya yaitu kota Pekanbaru. Kota Pekanbaru merupakan kota yang teridikasi zona merah dalam berkurun waktu yang sangat lama sehingga menyebabkan kebudayaan itu bergeser. Contohnya seperti dulu kita mudah untuk berjabat tangan sehingga berkomunikasi bisa lebih nyaman kini bergeser menjadi bersosial distancing dengan unsur protokol kesehatan. Perilaku manusia kini menjadi berubah di karenakan pandemi virus covid-19 ini. Seperti pada pasar dimana masyarakat dulu mudah untuk berbelanja, bersentuhan atau kontak langsung dan juga tatap muka. Salah satu upaya mewujudkan kegiatan perdagangan dan jasa yang perlu dikembangkan yakni dengan merancang Trade Center. Trade center merupakan sebuah pusat bisnis perdagangan yang menyediakan fasilitas perdagangan dan jasa dengan menyatukan agen bisnis yang terlibat dalam perdagangan dan diharapkan dapat memicu perkembangan ekonomi di daerah pelayanan. Untuk memenuhi kebutuhan Trade center yang aman dan nyaman terhadap lingkungan maka di terapkannya arsitektur Eco-tech yang memiliki teknologi berwawasan lingkungan.

One of these architectural styles is an Art Deco-style building that has its own character. This style first appeared in 1925 and developed until 1940. This European architectural style was adopted in various American buildings due to their condition in the time of the industrial revolution. The modern architectural movement that developed at that time also influenced the art deco style and gave it a modern touch. The Art Deco style in graphic design restores again decorativism but not necessarily in the form of ornaments. Decorative impressions can be achieved through the play of elements geometric, typographic blocks, textures and shades of color. Art Deco style has characteristics that are very distinctive and easily distinguished from other architectural styles. Art deco still exists in the spirit of medan city development as place of research evidenced by the many old buildings that are repurposed as well as new buildings that take the characteristics of Art Deco. One of them is the use of tower elements or one part of the building that rises slightly upwards and gives a magnificent impression.","source":"DOAJ","year":2022,"language":"","subjects":["Details in building design and construction.
