Division 2 DEFINITIONS

For the purpose of this Decision, the following definitions apply:

• ‘Q_usable’ means the estimated total usable heat delivered by heat pumps, calculated as the product of the rated capacity for heating (P_rated) and the annual equivalent heat pump hours (H_HP), expressed in GWh;

• ‘annual equivalent heat pump hours’ (H_HP) means the assumed annual number of hours a heat pump has to provide heat at rated capacity to deliver the total usable heat delivered by heat pumps, expressed in h;

• ‘rated capacity’ (P_rated) means the cooling or heating capacity of the vapour compression cycle or sorption cycle of the unit at standard rating conditions;

• ‘SPF’ shall mean the estimated average seasonal performance factor, which refers to the ‘net seasonal coefficient of performance in active mode’ (SCOP_net) for electrically driven heat pumps or ‘net seasonal primary energy ratio in active mode’ (SPER_net) for thermally driven heat pumps.
