Among the various renewable energy solutions, solar energy has emerged as a promising and scalable option. The efficiency of photovoltaic (PV) systems, especially in building applications, is highly dependent on the configuration of the panels—particularly their tilt angle. This study investigates the optimal tilt angles for PV panels installed on the south-facing façades of buildings in Babolsar, Iran, with the goal of maximizing annual solar radiation reception and energy yield. Using the Liu and Jordan isotropic sky model, combined with meteorological data and custom MATLAB simulations, monthly, quarterly, and fixed-angle strategies were analyzed. A system capacity of 1.5 m² panel area was assumed, with annual energy output ranging from approximately 336 kWh/year for a flat (0°) installation to 377 kWh/year with monthly tilt adjustment. Economically, the quarterly strategy offered the highest return on investment (ROI), with an estimated payback time of 7.8 years and a levelized cost of electricity (LCOE) of approximately $0.083/kWh. Environmentally, the optimized system reduces CO₂ emissions by approximately 180 kg/year compared to conventional grid-based electricity. A fixed optimal tilt angle of 30° was also found to be a practical, low-maintenance alternative. These findings provide both technical and environmental insights for enhancing the efficiency and sustainability of solar energy systems in Babolsar and similar climates.</p></div>","PeriodicalId":100117,"journal":{"name":"Architecture, Structures and Construction","volume":"5 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145165140","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}

We collected empirical data from <i>online videos, interviews</i> with key design related stakeholders, and <i>social media</i> showcasing local community involvement.

Our approach foregrounds the <i>entanglement</i> of material and social concerns through three interrelated lenses of care: 1) material practice (what is done), 2) affective involvement (who it involves), and 3) ethical intentions (why it matters). Our findings reveal that, despite ethical intentions, material practices are often driven by environmental agendas and tectonic aesthetics, overshadowing social concerns like global justice and local affective involvement.

This paper explores the adaptive reuse of farm buildings as a transformational response to unendurable spaces through an interdisciplinary reading of design as activism. Expanding mainstream concerns around the climate and energy crises, we address wildlife loss and ecological breakdown in co-existence with the fundamental social justice concerns that underpin them. Taking egg-laying hens as a much pained example, we engage with the question, <i>‘how might the de(con)struction of industrial farm structures be harnessed as a tool of activism, supporting liberation and sanctuary-making with ex-farmed animals?'</i> Recognising hens as designers and construction workers in their own rights, agency is extended towards nonhuman designers as a means towards spatial justice, reparation and (re)empowerment. Feminist participatory design methodologies are adapted for human-nonhuman collaborations, triggering an expansion of our communication and care practices to prioritise relational processes over formal outcome.

The present paper presents a novel sun-shading façade system comprising bending-active plates made of glass fiber-reinforced polymer (GFRP) arranged in three series vertically. Each elastic plate is supported at the corners by diagonal steel members, which are paired and equipped with rotating actuators to modify the opening angles. This modification induces elastic deformations on the bending-active plates, altering their shapes to provide varying levels of sun protection. The steel members act as scissor-like elements, supported on the curtain wall mullion using extruded aluminum pressure plates and U-channel rails. The bending-active plates serve as external horizontal louvres, offering adaptive sun-protection. A numerical investigation of a bending-active plate’s structural behavior is conducted through Finite-Element Analysis (FEA). Various symmetric curvatures of the plate are achieved through actuation of the scissor-like elements at specific opening angle values. The analysis considers the self-weight of the plate and a uniform distributed wind load of 1 kN/m<sup>2</sup>.
