Climate change sensitive sizing and design for nearly zero-energy office building systems in Brussels

As climate change continues, it is expected that the risk of overheating will rise in both new and existing buildings mixed humid zones Europe. This study introduced a novel sensitive sizing design approach for cooling heating systems nearly zero-energy office Brussels, Belgium, different weather scenarios. considered long-term effects on building performance. The were assessed using current future data from regional atmospheric model, MAR. To demonstrate approach, case Brussels was conducted. reference model first calibrated monthly energy use year 2019 ASHRAE Guideline 14. Then, evaluated with HVAC strategies their performances quantified. results indicated an increase as high 1.2 °C 13.5 kWh/m2 decrease overcooling low 0.3 10.9 by end century. In addition, due to coupled optimal sizing, resistant towards worst-case scenario century up 3.7 resistivity 20.2 resistivity. Finally, paper provided recommendations practice research based findings.
