Division 2 The annual electricity consumption per 100 m2 floor area (AEC) (in kWh/a electric per year); and the annual heating saved ((AHS), which means the annual saving in consumption of energy for heating (in kWh fuel gross calorific value per year) are calculated as follows, using the definitions in point 1, and the default values given in Table 1, for each type of climate (average, warm and cold):

$\mathrm{AEC}=t_a\times q_{\mathrm{net}}\times \mathrm{MISC}\times {\mathrm{CTRL}}^x\times \mathrm{SPI}+Q_{\mathrm{defr}}$ ;

$\mathrm{AHS}=t_h\times {\mathrm{\Delta {\rm T}}}_h\times {\eta }_{\mathrm{–\; 1}}^h\times c_{\mathrm{air}}\times \left(q_{\mathrm{ref}}-q_{\mathrm{net}}\times \mathrm{CTRL}\times \mathrm{MISC}\times \left(1-{\eta }_t\right)\right)$ .
