If your building fails to meet Part O compliance using the simplified method, dynamic thermal modelling is required.
Dynamic thermal modelling is able to offer the designer additional flexibility over the simplified method by factoring in additional mitigation measures such as solar shading.
It is therefore ideal for buildings with glazed facades or with a high percentage of glazing to floor area. Particularly where it is undesirable to compromise the original design.
To demonstrate compliance using dynamic thermal modelling, the CIBSEs TM59 methodology should be followed in accordance with the Part O mitigation hierarchy.
