SURVEY OF BUILDING INFORMATION MODELING INTEGRATION WITH HVAC SYSTEM DESIGN

Abstract

Building information modeling (BIM) has become a revolutionary digital approach to improve collaboration, precision, and productivity of the entire building and infrastructure lifecycle. BIM, through the development of 3D models that are data-rich, intelligent, allows the integrated planning, design, construction, and facility management of a shared and interoperable information environment. The paper will describe the basics of BIM and give a brief description of the main elements of this technology, including: 3D modeling, parametric design, data enhanced representation, visualization, simulation, and life-cycle management, as well as the key principles that ensure interoperability and collaboration, and the standard of information exchange. Simultaneously, the paper analyzes the design of heating, ventilation and air conditioning (HVAC) system with an emphasis on the critical role of appropriate system sizing to guarantee comfort, energy efficiency, cost-effectiveness and long-term functionality of the system. The recent trends in HVAC design, such as intelligent and adaptive systems, integration of renewable energy and BIM-based design processes, are also addressed. In addition, the paper discusses the modeling of the HVAC system with the help of BIM, which allows for designing the system correctly and analyzing its work, as well as coordinating the work of different disciplines using Revit MEP, AutoCAD MEP, Carrier hourly analysis program, and MagiCAD. Finally, the issues that are relevant to the BIM-based HVAC design are examined, such as the problem of data interoperability, the inability to integrate software, the regulatory void, and the shortage of unified component libraries. The paper highlights how BIM-based HVAC design can enhance building performance and sustainability and identifies the main research and implementation issues that need to be tackled to realize high adoption.
