District heating systems which off-set grid electricity

District heating systems which incinerate waste usually have NOx emissions higher than the levels set to achieve any BREEAM credits.

However, where a district heating system also generates electricity, this can be used to off-set NOx emissions from grid electricity. In such cases, the calculation methodology for CHP systems can be used to calculate NOx emissions for the district heating network.
