High Performing Heating, Ventilation and Air Conditioning (HVAC) Systems to Provide Excellent Indoor Climate in Energy Efficient Manner

Dear Colleagues,

We have global climate goals to significantly reduce greenhouse gas emissions. Energy use in buildings accounts for 40% of the total primary energy consumption. Buildings and especially technical systems of buildings are playing an important role in greenhouse gas eduction. High-performing heating, cooling and air-conditioning (HVAC) systems are very important from both the energy economy and indoor climate point of view. It has proven that indoor climate has a significant influence on users’ productivity and wellbeing. Thus, energy-saving measures should never be carried out by sacrificing indoor climate conditions.

In the near future, buildings should be smart enough to be able to sense, interpret, communicate, and respond to changing conditions, which are introduced based on the requirements of occupants when it come to indoor climate, operation of technical building systems, and demands of intelligent energy systems. The possibility to adapt in response to the perception of the occupants and further empower end-users makes it possible to enhance users’ satisfaction to indoor climate. Merged together with smart energy systems, building technical systems should be able to adapt their operation to the needs of the occupant and the energy systems and to improve their energy efficiency and overall performance. Technical solutions will then be able to optimize dynamic energy prices in the part of demand response control and thus enhance the flexibility of energy systems.

This Special Issue introduces novel HVAC solutions that make it possible to enhance user comfort, the performance of systems, and integration with smart energy systems. Research and review papers of novel systems and services with the aim to enhance energy performance, indoor air quality and thermal comfort, and HVAC system performance and energy flexibility are welcomed.
