Abstract

This paper elaborates a new energy performance benchmarking method to
support green tenancy agreements and other energy performance contracts.
The existing national energy reporting method does not categorise systemic
variations in patterns of use.

Results of a case study monitoring operational data of a multi-tenanted office
building are presented. The data reveals the actual designed spectrum of
occupant density accounts for a 44% increase in tenant energy demand per
square meter and a 112% increase in tenant energy demand per full time
employees [FTE], dramatically affecting the buildings internal gains, heating
and cooling requirements. The study highlights how low levels of occupancy
and extended operational hours can give a false representation of energy
efficiency.
