Energy Assessment and Reporting Methodology:
Office Assessment Method (CIBSE 2006)
describes a method for assessing an office building's energy and
building services performance that can be tackled by a spreadsheet
approach. The method has been extended to cover Bank and Agency
Branches, Hotels and mixed use Factory-Office and Industrial Buildings.
The approach can also be used for Schools and Residential Homes
etc with appropriate bench mark data.
primarily directed at finding out about and improving energy performance,
the results have a wide range of uses by building management and
design professionals, contributing to the virtuous circle of good
management and satisfied occupants. The method can be used:
identify poorly performing buildings and systems
indicate the cause(s) of poor performance
benchmark operating procedures including hours of use, and levels
of service provision including lighting levels and system efficiencies.
procedure has proved highly effective in use, forming a key part
of work for the PROBE investigations and the DETR's Energy Consumption
Guide 19 Energy use in offices.
Energy Assessment and Reporting Methodology Office Assessment Method
assesses a building's actual energy consumption per unit floor area,
and other aspects of performance, against established benchmarks
from Energy Consumption Guide 19, in three stages as shown below.
1: This stage provides a quick assessment in terms of energy
use per unit floor area, which can be carried out by in-house
2: If the building has special energy uses or occupancy, the
second stage is likely to be required, which can also in most
cases be carried out in-house.
3: For a full understanding of the performance of the building
and its systems, a Stage 3 assessment will require specialist
capabilities, but the results are of direct interest to building
owners and managers.
approach improves the level of understanding of building
and system performance and reduces the time taken to complete an
assessment. It provides a highly effective way of introducing feedback
into the design/construct/evaluate process as recommended in the
CIBSE Guide F: Energy efficiency in buildings.
buildings: the virtuous circle
high standard of energy efficiency is a good indication of high
management standards. Efficiently run buildings tend to have design
and operational arrangements which produce good staff relations
and satisfied occupants
assessment process can help improve not just energy management but
building design and management: the investigations and actions required
to improve energy efficiency also tend to improve building design,
management and occupant satisfaction.
