Frequently Asked Questions
In Part 3.12 in Volume Two of the NCC it gives two options for compliance. One option is to achieve an energy rating (or star rating) using house energy rating software. The other option is to comply with the requirements listed under the Part for building fabric, external glazing, building sealing, air movement and services.
Note: the requirements for services must be complied with even when an energy rating is used. Further information can be found in the NCC Volume Two Energy Efficiency Resource Kit.
Once the classification of the building is determined, the rise in storeys must be calculated under C1.2. Once the classification and rise in storeys is known, these can be applied under table C1.1 to show the type of fire resisting construction required (i.e. type A, B or C). Further information can be found in the NCC Volume One Fire Safety Resource Kit.
