BIM-based HVAC system design for a new indoor sports arena: a real case study

This thesis presents a real case study of HVAC system design and modeling using BIM methodologies for a sports complex to be constructed in the municipality of Pistoia (PT). The sports arena is divided into multiple zones, each served by different types of systems. Specifically, this work focuses on a full air and primary air system implemented through two Air Handling Units, VRF-based air conditioning systems, ventilation systems for air renewal using cross-flow heat recovery units, and the hydronic system serving the AHU coils, post-heating coils, and domestic hot water production. Domestic hot water is produced through the use of a multifunction (or polyvalent) heat pump combined with a booster heat pump. The project was developed using Autodesk Revit software and employs dedicated plug-ins, such as MagiCAD, for system calculations, sizing, and distribution network modeling. The design complies with UNI EN 10339, UNI EN 16798, and CONI regulations, as the facility is intended for sporting activities, and the design decisions are based on these standards. Furthermore, the design and implementation of the systems must meet the requirements set by the contracting authority, which imposes constraints related to municipal regulations, budget limits, and specific requirements defined during the tendering process and subsequent project development. The key aspect of the modeling process in Revit is interdisciplinary coordination, aimed at optimizing the design and implementation of the HVAC systems.
