ABSTRACT: The paper presents the
results of the investigations into the indoor climate and energy efficiency of
ventilation devices in residential buildings and nursing homes. The indoor
climate studies discussed in the article were conducted in a nursing home where
room ventilation is based on Meltem Air Handling Units (AHU). Similar studies
have been carried out in apartment buildings where CO2 levels in
bedrooms were compared before and after renovating the ventilation with Meltem
AHU and installing exhaust fans in the bathroom/WC and kitchen. Tenants
evaluate the use of Meltem AHU in apartments very positively. The article
presents the efficiency results of Meltem AHU with different external air
temperatures conducted in apartments in real-life situations. The study shows
that skilful renovation of ventilation in old apartment buildings enables to
achieve good indoor climate and energy saving at the same time.
