Energy Efficiency for Large buildings (over 300m2) excluding industrial
There are changes to roof, window, wall and underfloor insulation requirements and also the creation of new documents for large buildings - H1/AS2 and H1/VM2.The changes will reduce the energy needed for heating and cooling of large buildings by 23% on average compared to previous requirements.
The new minimum thermal resistance values as noted in H1/AS2 and H1/VM2 are summarised in the table.
Significant improvements for large non-residential buildings
The changes will result in a significant improvement on the energy efficiency of large buildings. Dependent on climate zone, the changes will improve the energy efficiency of various types of buildings as shown in table.
At a high level the changes will result in an average 23% reduction in energy use by large buildings.
