5.3 Impact on Local Air Quality

Decorative gas/ethanol fires - KBCN1301

Although fires may be decorative, if they are permanent features of the home that burn fuel to produce heat, they will have an impact on local air quality. They should be assessed in the Impact on Local Air Quality issue.

Oil-fired boilers benchmarks - KBCN1293

It has come to our attention that there is an error in Table 35, relating to the NOx emission benchmarks for oil-fired boilers. The table below confirms the correct benchmarks.

Appliance type and unit	Fuel	7 credits (Low pollution location)	7 credits (High pollution location)	10 credits (Low pollution location)	10 credits (High pollution location)
Boiler (mg/kWh)	Oil	56 73	56	55 67	50

This will be confirmed in the next update of the technical manual, but can be applied immediately to HQM ONE projects.
