10.3.2 GreenhouseGasEmissionReductionandAvoided Emissions The emission reduction are calculated based on the recorded actual energy con- sumption for both the non PSH and PSH. The results extrapolated for the whole winter season considering110daysof heating arepresented in the following table (Table 10.4). These results showanemission reductionpotential fromthePSHtechnologyof 0.366 tCO2e/year. However this does not take into account the higher indoor temperature in the PSHcompare to nonPSHand the emissions avoided using the PSH technology.
