Abstract
This study has used computational fluid dynamics (CFD) supported by field measurements to investigate the relationship between the zonal supply air strategies (natural ventilation (NV), mechanical ventilation (MV) and mechanical ventilation with heat recovery (MVHR)) and thermal comfort in the largest non-domestic certified Passivhaus building in the UK. The results show that, depending on the selected thermal comfort standard and internal heat gains, a thermally comfortable environment could be achieved by supplying air in a range of 9°C – 26°C for MVHR, versus 17°C – 29°C for NV. The findings indicate that a mixed mode approach, using auxiliary heating and cooling, may be necessary for optimal year-round thermal comfort and energy efficiency in non-domestic Passivhaus buildings in the UK climate.
