Abstract
The facility strategy of the City of Espoo emphasises
improvements in the energy efficiency and efficient use
of buildings. The design phase of a building is crucial
and when the building is in operation, it is crucial to
use control systems correctly. Further, in order to
encourage relevant efficiency efforts, it is essential to
know how to measure energy efficiency in the building
operation phase. This requires an understanding of the
correlation between building occupancy, space efficiency
and energy efficiency.
Energy efficiency is typically measured as energy
consumption per unit of area kWh/m2 per annum. The
specific energy consumption is an effective way to
measure the technical properties of a building and to
guide its design but it neglects issues related to
building occupancy and space efficiency.
This paper explores ways in which building usage and
occupancy influences the measured energy consumption in
Finnish daycare centres and school buildings. The study
adopts existing energy efficiency indicators and
introduces a new indicator for building energy efficiency
which takes into account both space and occupancy
efficiency.
