Heating plant emission rate
According to the Domestic Building Services Compliance Guide published by HM Government in 2013, the term ‘Heating plant emission rate (HPER)’ refers to:
… the annual carbon dioxide emissions from fuel and power consumed by the heating plant, offset by the emissions saved as a result of any electricity generated by the heating plant, divided by the heat output over the year. It is measured in units of kg of carbon dioxide per kWh. To calculate HPER it is necessary to know the plant size ratio.
The plant size ratio (PSR) is the nominal heat output of the heating plant divided by the design heat loss (the average heat loss of the building on a cold day with a temperature differential of 24.2°C).
Note: The heating plant emission rate includes any auxiliary space and water heating that may be necessary, i.e. it represents the performance of all heating plant needed to provide space and water hating service to the building, assuming a standard demand pattern.
Note: For a given heat demand, the plant size ratio determines the part-load condition for the heating plant.
