At the recent CIBSE Presidents Awards night and 125th anniversary celebrations held at the Institute of Directors, the Napier Shaw Bronze Medal for Research was won by Modelling elevator traffic with social distancing in a university classroom building, by David Swinarski, which studied the potential negative impact of social distancing on vertical traffic in a university building, and the effect of four interventions to improve it. David developed a simulation tool to assess the impact of various interventions on traffic carrying capacity of lift groups during the COVID-19 pandemic, when occupancy of lifts was curtailed as a means to reduce transmission risks.
