existing controls to match actual requirements of occupancy, or installation of
small items (e.g., thermostats, insulation of sections of pipework, fi xing cracks
in window frames).
Medium-cost measures may require little or no further study and design
and will consequently take longer to implement. The approximate range of
capital cost is between $500 and $10,000 per ECM. Common investment mea-
sures include installation of new and replacement of old controls for heating,
cooling, or lighting; changing of lighting fi xtures to more effi cient ones; insu-
lation of sections of pipework, and insulation or refurbishment of roofs, win-
dows, or fl oors to reduce solar gains and drafts.
High-cost measures are expected to need further detailed Level II study
and design. These measures may require an executive level of approval before
implementation. Such measures could include building walls insulation, re-
placement or upgrading of plant and equipment, boilers, and chillers; installa-
tion of BMS; or decentralization of the boiler plant or its replacement for CHP
scheme.
5.12.6 Report Quality Check
The project manager (or the report coordinator) should pay special attention
to the following issues when reading the fi nal draft version of the report:
The data is logical and benchmarking fi gures match (building volumes, ■
energy consumption, etc.)
The saving potential is realistic
■
The proposed measures are appropriate for the building type concerned ■
The technical content is okay ■
The technical specifi cations of the saving measures are okay ■
Rough check on how the savings have been calculated ■
There are no “ghosts” or cut-and-paste errors from previous reports in ■
the text
5.13 Summary Data for Monitoring
When energy assessments are being carried out in large numbers for large sites
with many buildings, there are usually dozens of energy conservation measures
for each site. To keep track of the saving measures during the reporting phase
and also to make the decision-making and implementation of the measures
easier, a summary table of all the suggested measures is recommended.
The table should include the following data:
Name of measure and what building or area it deals with ■
Saving potential in heating, electricity, and water consumption ■
