Optimal balance between energy demand and onsite energy generation for robust net zero energy buildings considering future scenarios
Net-zero energy buildings have usually very low energy demand, and consequently heating ventilation and air conditioning (HVAC) systems are designed and controlled to meet this low energy demand. However, a number of uncertainties in the building use, operation and external conditions such as climate change and occupant behaviour can influence the energy demand. Considering these variations, the currently designed net zero energy buildings will not always be able to provide the required indoor environmental quality. A proper balance between energy demand, HVAC and renewable energy systems needs to be investigated to meet the performance requirements over the building life span. Therefore, in this work, performance optimization of various net zero energy building designs, with different energy demand and onsite energy balance, is carried out under uncertainties due to future scenarios to minimize the performance variation across all future scenarios. The design with optimal performance and low performance variation across all scenarios is identified as the most preferred robust design solution.
