Useful energy requirement per m2 per degree-day for space heating
The efficiencies by fuel are the following: electricity (97%), heat (95%), LPG (75%), heating oil (72%), fuel oil (76%), hard coal (65%), lignite (65%), , wood/renewable (55%), gas (80%), the values were endorsed at an ODYSSEE meeting, following a review of the values used by different countries, in particular Denmark.
The difference of variation between unit energy consumption in useful and final energy show the impact of fuel substitutions.
