Energy and Environmental Effects of Human Habits in Residential Buildings Due to COVID-19 Outbreak Scenarios in a Dwelling near Rome

The COVID-19 pandemic and resulting containment measures have shown that energy consumption in buildings is linked to several factors, such as living habits, occupancy profiles, heating ventilation air conditioning (HVAC) systems. This paper addresses the influences of factors on a residential building, analysing different scenarios (pre-COVID-19, lockdown, post-COVID-19), terms discomfort needs, through new hourly calculation method (UNI EN ISO 52016). Energy environmental effects were studied real case study near Rome by varying lighting appliance schedules, HVAC Results show that, during period, lockdown scenario led lowest hours (−29% average), but highest cooling period (up +154%, +28% average). same reasonable reduction needs for (−14%), also highlighted significant increase (+60%) period. underlines how has influenced behaviours buildings. Moreover, points out importance systems, discomfort, which could provide results are more reliable.
