Abstract

Schools are definitely among the highest densely occupied indoor environments with continuous occupation. According to the pre- sent knowledge about airborne carried diseases, the infection risk for SARS-CoV-2 could reach to significant values especially in poor ventilating conditions. The infection risk can be reduced by dilution of the viral agent concentration, provided by air-change, whether by infiltration, aeration (window opening) or mechanical ventilation. The present work, after a brief survey on ventilation requirements for schools in Italy, compares different strategies to account for dilution both in terms of infection risk control and of energetic and comfort aspects. The paper is split into two parts: this part 1 deals with energetic aspects, while the second one will examine air quality and Sars-CoV-2 risk assessment. Each part has its own specific nomenclature and methodology.
