Monitoring energy usage in the building is a key component in maintaining an efficient
operational building environment with energy use target set within 140kWh/m

/annum
and emission of less than 1007 tons of CO2/ per year. The building has sub metering
technology to monitors gas and electricity consumption at quarter–hour intervals allowing
the building manager to assess whether the building was on course to meeting the
targets. In addition, the data center within the McClay is sub metered separately due to
the large number of high-energy demand computer processes and other plant and
hardware equipment (RICS, 2010).
The metering data combined with the “footfall” i.e. number of people within the building
at any one time, allows the identification of direct links between user behavior and
energy usage allowing for opportunities to reduce energy load. A strategic response to
this is the limiting of the opening hours on certain floors of the library or reducing the
number of computers in operation at any one.
Results
Detailed results of the questionnaire, issued to employees in the case study building, are
available on request and displayed here are the breakdown of responses with respect to
each statement contained within the questionnaire. The following pages display figures
detailing the breakdown of data gathered from respondents in the McClay library, with
respect to the structure of the questionnaire. The first selection of graphs, seen in table 2
details the breakdown of characteristics of employees in the McClay library, including
status of employee, years experience in current position and time spent in front of a
computer screen each day.
