# Commission Decision of 1 March 2013 establishing the guidelines for Member States on calculating renewable energy from heat pumps from different heat pump technologies pursuant to Article 5 of Directive 2009/28/EC of the European Parliament and of the Council (notified under document C(2013) 1082) (Text with EEA relevance) (2013/114/EU), Division 4: CALCULATION EXAMPLE

Extent: E+W+S+N.I.

The table below show an example for a hypothetical Member State located in average climate conditions, which has 3 different heat pump technologies installed.
The Member State in this hypothetical example did a survey of installed reversible air to air heat pumps and concluded that the equivalent of 48 % of the installed reversible heat pump capacity were used fully for heating, instead of the 40 % assumed in these guidelines. The HHP value is therefore adjusted up from 710 hours, which assumes 40 % and set out in Table 1, to 852 hours, which is representative for the estimated 48 %.
