Abstract
The building sector contributes up to 30% of global
annual greenhouse gas emissions and consumes up to 40% of
all energy. Failure to encourage energy-efficiency and
low-carbon in new builds or retrofitting will lock
countries into the disadvantages of poor performing
buildings for decades. The journey towards low-carbon and
energy efficient buildings starts with good design,
commissioning and measuring. The share of energy costs
can be up to 50% of all maintenance costs [7] in Finland.
In the studied buildings the average costs were 39% for
daycare centres and 45% for schools. Since the share of
energy costs is remarkable in maintenance, it is
important to find out the most concrete indicators to
measure energy efficiency in practice. This study
explores ways in which building usage and occupancy
influences the energy cost in Finnish daycare centres and
school buildings. This study shows that energy costs vary
a lot between different energy efficiency indicators,
i.e. there is great variation in energy costs regardless
of the building age and when child or student density
varies. Results indicated that actual use of space is
profiled in the operational phase where the energy costs
variation is remarkable.
