6.2 Signing an entrusted audit agreement
The auditing unit and the auditing entrusting party sign an agreement entrusted
to conduct an energy audit, as the basis for the auditing unit to conduct an
energy audit.
6.3 Implementing an energy audit
Perform data collection, collation, verification, conduct relevant calculation
analysis and review in accordance with the requirements of the task proposal;
make necessary on-site examination and testing of the audited unit.
6.4 Proposing an energy audit report
After the audit is over, the auditing unit shall submit an audit report to the
auditing client within 15 days.
7 Preparation of enterprise energy audit report
7.1 The enterprise energy audit report is divided into two parts. the abstract and
the main text.
7.2 The summary of the corporate energy audit report shall be placed in front
of the text and the number of words shall be within 2000 words.
The summary shall include a brief description of some of the following.
a) The main tasks and content of enterprise energy audit;
b) The enterprise energy consumption structure (in the audit period);
c) Various energy consumption indicators,
d) Evaluation of energy costs and energy use effects,
e) Financial analysis and economic evaluation of energy-saving
technological renovation projects;
f) Problems existed and energy saving potential analysis;
g) Audit conclusions and recommendations.
7.3 The main text of the enterprise energy audit report shall be prepared in
detail. The report shall include a detailed description of the contents listed in
7.2. In addition, the following shall be included.
a) Enterprise profile (including the main process characteristics of the
enterprise, the position of the enterprise in the domestic and the same
Ri - The total cost of the ith energy consumed by the enterprise, 10000
yuan/year.
Note. Usually it is in the unit of year; if the audit period is not 1 year, the auditing
unit or personnel may determine the calculation unit by itself based on actual
conditions.
A2 Direct production process unit product energy cost
A2.1 The energy cost per unit of product in the direct production process is
calculated in accordance with the physical energy consumed per unit product
and the unit price.
A2.2 The physical energy consumption per unit of product can be calculated
based on the physical energy consumption of the production system and the
output of qualified products during the audit period.
A3 Indirect energy consumption and energy loss
A3.1 Enterprise energy audit shall examine the level of indirect energy
consumption of enterprises, analyze the proportion of the indirect energy
consumption in the total energy consumption of enterprises.
A3.2 Enterprise energy audit shall analyze the magnitude and cause of energy
loss.
A3.3 When calculating the enterprise product unit comprehensive energy
consumption and the enterprise exit-factory product unit energy cost, it shall
allocate the indirect energy consumption and energy loss to the energy
consumption indicators of each product in accordance with the proportion of the
direct production energy consumption of the product.
