“…Directly related to primary energy savings, decarbonization, and indoor air quality, decentralized ventilation is a modern solution for many houses, apartments, offices, schools, and kindergartens [1]. Decentralized ventilation with heat recovery has become a reliable energy-saving measure that reduces heat energy consumption in buildings by about 2 to 10% [2]. Most new and renovated old residential buildings that meet European energy efficiency requirements still create airtight conditions for building occupants [3].…”

The article presents an experimental field study of the influence of environmental factors on the functionality of a commercial decentralized ventilation device for regenerative utilization of heat from the exhaust air, intended for installation in an external wall of buildings. The experiments included measurements during the winter and summer seasons. Real operating situations with two regenerative heat exchange matrices are presented and tested. The results of the experiments show that the functionality of the ventilation and heat recovery device does not meet the characteristics that the device shows under standard laboratory conditions.

Mechanical ventilation systems have acquired relevance in the past years in order to guarantee the hygrothermal comfort and indoor air quality (IAQ) in highly retrofitted residential buildings. The optimization of control strategies could provide a solution to this existing trade-off between energy efficiency, hygrothermal comfort and IAQ. In this publication, we propose a co-simulation approach (using EnergyPlus and Modelica) and a mathematical approximation of the discomfort of the occupant (namely, quadratic for relative humidity and exponential for CO2), and apply them to a demand controlled ventilation (DCV) scheme. Results show that this approach provides around 10% energy savings, while improving the thermal comfort, without compromising the humidity comfort or the IAQ. Finally, the developed functions could allow the control schemes to adapt to different occupant preferences, showing potential for future work.
