CASE STUDY OF HVAC SYSTEM DESIGN WITH PARTIAL BIM INTEGRATION

The reduction of greenhouse gas emissions and primary energy consumption have been among the most discussed topics in recent years. Within this context, the construction of new buildings, particularly the systems serving them, including Heating Ventilation and Air Conditioning (HVAC) systems, plays a significant role. This paper presents a case study on the design of HVAC systems for a newly constructed building primarily dedicated to offices and meeting rooms. The objective was to combine the requirements for comfort and well-being within the indoor spaces with the goal of minimizing energy consumption and maximizing the efficiency of the developed systems. The climate control is ensured by two versatile heat pumps capable of supplying the required thermal energy to various hydronic terminals, such as wall or floor-mounted fan coil units, as well as radiant floor and ceiling panels. Regarding ventilation, three air handling units were designed to provide the necessary air volume for indoor air renewal and humidity control. Air volume regulators were integrated into the duct network to ensure the precise amount of air flow required. In addition to these systems, a comprehensive control system was implemented to manage the numerous variables and diverse thermal demands that can occur within the building. Simultaneously with advancements in machine technologies, there have been developments in software tools available to designers. In this project, the Building Information Modeling (BIM) approach was used. This tool was employed to create a three-dimensional model of the building and its systems, allowing for the association of parameters with objects, facilitating coordination among different workgroups, managing and resolving system interferences, extracting material quantities, and implementing a construction schedule.
