Energy balances, thermal performance, and heat stress: Disentangling occupant behaviour and weather influences in a Dutch net-zero energy neighborhood

•High resolution data from a Dutch net zero energy neighborhood is analysed.•Most buildings are positive energy, emit less carbon than they offset.•Large occupant differences in energy demand are visible across the households.•Occupant preferences and weather conditions greatly influence thermal energy demand.•Due to the high thermal efficiency, there is a high risk for summer overheating.
