Where a mandatory planning condition exists (eg to attach to a District Heating Scheme), this will clearly affect the number of options available in a feasibility study. In such cases, compliance can still be achieved where evidence on the planning condition restrictions is provided, and it is clarified how this excludes other technologies from being considered.
The feasibility study will still need to be carried out to cover the remaining energy needs of the building (eg Electrical and lighting load in the case of a district heating scheme).
