Influence of Building Orientation on Instant, Delayed Sensible and Latent Energy Loads: A Building Information Modelling (BIM) Based Analysis

Abstract

The orientation of a building plays a crucial role in its energy performance, affecting both immediate and delayed thermal responses. The influence of instant, sensible, and latent energy loads on a building is a critical aspect of understanding and optimizing its energy performance. These three components play a crucial role in shaping the thermal dynamics and overall energy consumption of a structure. Building Information Modelling (BIM) offers a sophisticated framework for analysing and simulating these intricate relationships, providing a comprehensive understanding of the dynamic interplay between building orientation and energy loads. BIM represents a holistic digital representation of a structure, encompassing not only its geometric attributes but also the intricate interplay of spatial relationships, material characteristics, and performance parameters. The research employs BIM-based simulations to evaluate the instant, delayed sensible, and latent energy loads associated with different building orientations at 0°, 45°, 90°, 135° and 180°. By leveraging BIM's capabilities in integrating diverse building parameters and environmental factors, the study aims to unravel the nuanced interactions that contribute to energy consumption patterns. Through this approach, the research contributes valuable insights into optimizing building design for enhanced energy efficiency. The findings of this study have practical implications for architects, designers, and policymakers involved in the construction and retrofitting of buildings. By delineating the influence of orientation on energy loads, the research aids in informed decision-making, promoting sustainable practices in building design and operation. This BIM-based analysis offers a robust methodology for assessing and optimizing energy performance, contributing to the ongoing discourse on environmentally conscious and energy-efficient building practices.
