Its a heating load calculation based on Heating Degree Days (HDD) at a baseload of 15.5oC (Standard for Ireland/UK)

TAi - internal required temp
TAo - Outside temp
Q - Heat Input Power
Nseasonal - seasonal efficiency of the heating unit (e.g. boiler, CHP)
Correction Factors - Assume heat losses, wind ...etc....
E - heat load over period (based on HDD, Ta)

I remember the calculation but cant find the linkfor the explanation
