Dron Kaushik’s abstract to the CIBSE Technical Symposium to be held in April 2027 was accepted. The paper will be based on the simulation work using the newest CIBSE weather files to study the impact of urban context and climate change on the energy use for heating and cooling for a primary school placed on a site in London. The site was selected to be in the same area studied (via measurements and simulation) under the Urban Albedo EPSRC project.
