Abstract

The growing demand for building energy efficiency has driven the development of active façade systems that harness solar energy. This study aims to evaluate the performance of a hybrid solar façade collector that utilizes two types of fluids—air and solar fluid—to enhance primary energy efficiency. The method employed is numerical simulation using the specifically developed MITHRA software, based on two-dimensional finite difference modeling and climate data from DWD. Validation was conducted through experiments using four test collector units. A matched-flow control strategy was implemented to optimize system operation based on actual energy efficiency. The results indicate that the use of dual fluids does not always outperform single-fluid systems; however, system efficiency improved significantly—by up to 15%—when the control strategy was applied. The MITHRA software also proved effective as a planning tool for the design of solar energy-based building façades.

Abstract

The background of this study lies in the urgent need for building energy simulation (BES) tools that can be used by architects during the early design stage to support the achievement of nearly zero-energy buildings (nZEB) targets. This research aims to identify and evaluate CAD-integrated BES tools that are suitable for the conceptual design phase of buildings within the Swedish context. The methodology includes a literature review, screening of BES tools, testing on a Stockholmshus case using industry-standard values, and multi-criteria analysis through the Delphi method. The results indicate that EcoDesigner (ArchiCAD), Energy Evaluation, designPH (SketchUp), and Sefaira are the most relevant tools, although limitations persist regarding simulation assumptions, result consistency, and compliance with local regulations. The findings highlight the need for model calibration and further development to enhance the reliability of energy simulation outcomes during the early design stage.

Abstract

The development of virtual reality (VR) technology has transformed the way designers and users perceive and interact with space within the context of architecture and interior design. However, a deep understanding of the meaning of virtual space from the user's perspective remains limited, particularly in urban contexts such as Mumbai, where physical space is increasingly constrained. This study aims to explore and analyze the meaning of virtual spatial experiences in VR-based interior design in the city of Mumbai using a phenomenological approach. A qualitative research method was employed, utilizing phenomenological inquiry through in-depth interviews, participatory observation, and visual documentation involving twenty participants from diverse professional, academic, and end-user backgrounds engaged with VR technology in interior design. Data were analyzed using the Miles and Huberman technique, with validity ensured through credibility, transferability, dependability, and confirmability tests. The findings reveal that virtual space is not merely perceived as a technical visualization tool, but has evolved into an affective and conceptual realm, emotionally, imaginatively, and personally inhabited by its users. The experience of virtual space demonstrates deep user engagement, significantly shaping perception, understanding, and decision-making throughout the interior design process. These insights broaden conceptual understanding in digital architecture and offer practical implications for more participatory and user-centered design approaches, especially within densely populated urban environments such as Mumbai.

Abstract

Dutch colonial buildings in Semarang have high historical and architectural value; however, many of their façades have experienced material degradation in the form of hairline cracks, structural cracks, and plaster peeling due to the humid tropical climate and the age of the buildings. Conventional visual inspection methods tend to be subjective, time-consuming, and pose safety risks to surveyors.This study aims to develop a vision-based assessment approach to automatically detect and identify façade cracks using the YOLO algorithm. The research method involved collecting 2,400 images of colonial building façades in the Kota Lama area of Semarang using a 24 MP resolution camera and a drone at a height of 5–15 meters. The dataset was manually annotated using a bounding box format and divided into training data (70%), validation data (20%), and testing data (10%). The model was trained using YOLOv8 with an input resolution of 640×640 pixels, 150 epochs, a batch size of 16, and AdamW optimization. Performance evaluation used the metrics Precision, Recall, and mAP@0.5.The results show that the model achieved an mAP@0.5 score of 0.91, with a Precision of 0.88 and Recall of 0.86, and was capable of detecting hairline cracks larger than 2 mm in real time. This approach has proven effective as a digital-based conservation support system for historic buildings.
