Abstract
In the wake of the worsening of the energy crisis in winter 2022, several public administrations in Italy recommended simple energy systems operation control measures, to be implemented in the local building stock to reduce energy consumption and produce economic savings in the short term. In particular, in the municipality of Bolzano, Italy, these measures ranged from lowering the heating setpoint temperature, implementing systems setbacks or ON/OFF setting and reducing ventilation rates. However, these measures were applied to all buildings, without distinguishing vintage and type, with the risk of worsening the indoor environmental quality (IEQ) in some of them. In this context, this study focuses on the analysis of two kindergartens of dated and recent construction in the city of Bolzano, with the aim of evaluating the applicability of the proposed energy-saving control measures on buildings representative of “old” and recent constructions. Results proved the importance of carefully considering building specific features to design effective HVAC systems operation measures, able to optimize the systems performance and guarantee adequate IEQ conditions.
