Ene20 Carbon intensity district heating and cooling

*contributes to 50 credits available for operational energy rating

Aim

To minimise operational energy consumption and the associated carbon emissions by employing effective energy management practices.

Question

1. If known, what is the carbon intensity of the district heating system in kgCO₂eq/kWh delivered heat? 
2. If known, what is the carbon intensity of the district cooling system in kgCO₂eq/kWh delivered cooling?

Assessment criteria

Criterion	Assessment criteria
1	The carbon intensity of the district heating and/or cooling system would be sourced from the supplier of this system.
2	The carbon intensity value should be an average annual value and should be provided for the most recent year available.
3	As a minimum, the carbon emissions from all fuels used to generate heat or to generate cooling must include all direct (scope 1) emissions and indirect (scope 2) emissions associated with any electricity used to generate heat or to generate cooling and take account of distribution losses.

Evidence

Criteria	Evidence requirement
-	The evidence below is not exhaustive, please also refer to the ‘BREEAM evidential requirements’ section in the scope of the Guidance for appropriate evidence types which can be used to demonstrate compliance.
1	Relevant literature/records/data or other information from the district heating and/or district cooling supplier stating the carbon intensity of the system.
