The Corona global pandemic, which emerged in the last quarter 
of 2019, has affected the global economy, resulting in many 
sectors such as energy, buildings, and industries being seriously 
affected by the epidemic. Studies of COVID- 19 transmission 
have indicated a direct relationship between the number of 
occupants and the risk of infection. The aim of this study is to 
focus on the work density strategy as one of the main overlooked 
factors affecting energy consumption, the risk of transmission of 
viruses within buildings, and to determine optimal works density 
to reduce energy consumption in buildings, especially 
educational buildings. 
To this end, the application approach has been used by using the 
COVE-TOOL and COVID-OCCUPANCY projects to apply the 
proposed occupant density after new design considerations to one 
of the classrooms and to evaluate their stays to reduce the spread 
of epidemics and rationalize their energy.
