The EMIS Audit

What Why
Information regarding the tariffs
applying to utilities (Fixed
charges, unit consumption
charges, billing periods, taxes,
demand and distribution
charges…etc)
Demand profiles if available
showing typical summer, winter
weekday and weekend demand
for utilities such as gas or
electricity.
Sub-meter Information
Sub-metered consumption and
demand (if available) data.
Depending on the frequenc y of
the data – if monthly then 3
years, if weekly then one year.
Production Data:
Monthly / W eekly production
rates (either tonnes
manufactured, sales tonnes,
sales units, raw materials inputs,
etc) of key product groups.
Ideally over the same period /
frequenc y as the sub-meter data
Management System Information
Details of any production or
environmental management
systems in place, e.g. Six Sigma,
TPM, TQM, ISO14001, e tc
Details of any environmental
legislation pertinent to the site at
a Federal, State or Municipal
level and impact on site
3.3 Preliminary Analysis
W ill be used to calculate the cost savings from
EMIS implementation. Knowledge of the split
between consumption and demand charges is
critical in terms of calculation of cost sav ings.
Are there opportunities for load profile
management to reduce demand charges? Is
there evidence of excessive consumptio n
during non productive periods?
This is to provide sufficient data points to allow
regression analysis with a degree of
confidence. W ill allow calculation of savings
potential at an EAC or sub-meter level as well
as at a site level.
In order to do the data analysis required to
estimate savings potential, the auditor will
require a consistent data set. Having energy
data at a different timing or frequenc y to the
production data will limit their ability to derive
valuable insights.
EMIS should be embedded within the context of
an energy management s ystem. The objective
of this request is to understand whether the
site has experience with operation of formal
management s ystems. If Yes, then EMIS
should be integrated within the ex isting
systems and structures
These may act as either stimuli or constraints
for EMIS implementation. Knowledge of the
regulatory context is useful to understand the
regulatory drivers that the organization is
facing
There are a number of types of analysis that are useful to do prior to arriving on
site:
� Breakdown of consumption by Utility – this will help define which utilities
should be the focus for expenditure on new metering;
