Techno-economic and environmental evaluation of different building HVAC systems through a dynamic approach

The field of indoor climate control plays a crucial role in advancing energy efficiency and sustainability within the building environment. HVAC systems account for a substantial share of total energy consumption and greenhouse gas emissions, thus representing a key factor in decarbonization strategies and in mitigating environmental impacts. At the same time, the growing emphasis on operational costs and the life cycle performance of building systems underscores the need for an integrated perspective that combines both energy and economic considerations, promoting solutions that are not only efficient and reliable but also sustainable over the long term. This work aims to investigate the energy, environmental and economic comparison of 4 HVAC generator subsystems.
