Purpose
Gathering the right data, with the appropriate amount of detail, is a key component to
realizing the maximum savings from an energy audit. However, the process for audit
data collection is currently non-standardized, and crucial data can be overlooked or the
level of detail is insufficient for the required energy and financial analyses. To address
these issues, we have created these template data collection forms. The purpose of
these sample forms are to assist building energy auditors collect data required to
complete comprehensive energy and financial analyses of proposed modifications to
the building. These forms are best suited to Level II and Level III audits.
Energy conservation is the practice of decreasing the quantity of energy
used. It may be achieved through efficient energy use, in which case energy use is
decreased while achieving a similar outcome, or by reduced consumption of
energy services. Energy conservation may result in increase of financial capital,
environmental value, national security, personal security, and human comfort.
Individuals and organizations that are direct consumers of energy may want to
conserve energy in order to reduce energy costs and promote economic security.
Industrial and commercial users may want to increase efficiency and thus
maximize profitIn these guidelines an energy audit and an energy analysis mean
any comprehensive analysis related to energy conservation, which is performed at
an industrial site. An energy audit model means a procedure that is used to reflect
the extent of the auditing work, its performance and reporting. In Finland, audit
models have been developed for surveying objects of different type, size and age.
These guidelines apply to auditing models applicable in the industry sector. In
these guidelines the field of application is the foundry industry that represents an
energy intensive sector of industrial production. The guidelines for audits are to
be updated within this project.
Energy Audit Guidelines:
In general the guidelines for energy related audits are designed in three
stages. The first stage gives the general guidelines for energy-related audits
defining the general and administrative procedures.
The second level is composed of the performance and reporting guidelines,
developed, which include instructions and requirements tailored to fit a particular
auditing object and must be complied with taking into consideration the special
features of the particular object.
The third level is the Energy Auditors Manual that describes good auditing
practices, and provides instructions for performing the actual audit. This level is
the key issue in the publication containing production technology, maintenance,
building installations and constructions and gives practical guides to accomplish
auditing tasks and offers proper hints for auditor to create options of energy
savings.
of the saving actions in energy supply can be taken into account with accurate
costs. It is important to know who is responsible for which energy cost and to aim
the proposal and saving actions correctly. Of particular importance, is to know
and to include in the energy audit report, the rate of electricity use for different
times of the audit site (different usage targets) and to calculate the savings actions
with real energy prices (taking into account also the other electrical consumption
components, among others reactive power demand charges).
If the electricity supply of the audit site has been competed in the market,
and it is not possible to display the real purchase price in the report, the accurate
prices should, however, be presented (preferably close to the real situation) at
different times. Cost and savings calculation are based on these prices. These
savings calculation can then be specified with correct price information at the
audit site. Also, this issue has to be clearly presented in the report. If the price
competition in the market is carried out for example, yearly, the price will vary
from year to year. The real price for cost savings of saving actions, therefore,
does not exist.
In the electricity supply part of the audit report will be presented at least the
following: an annual average price from the energy charges of electricity use in
the audit site (excluding the fixed charges), an average energy price at different
times (dates are determined in accordance with definition of tariffs), power
charges in the effect tariff site and their determination and an annual average
price of electricity supply including power charges.
In reporting the prices, it must be clearly remembered to tell whether they
are value-added taxes or tax-free prices.
If the electricity supply price of the audit site varies at different times, it is
not enough that average prices are observed in the savings calculation. For
example, the cost impact of energy use and savings calculation from different
devices or device groups can be noted the following:
Energy consumption of outdoor lighting is scheduled mostly during the
wintertime when the electricity cost is calculated using wintertime prices.
After this audit, you have 18 months to make some or all of the upgrades
your energy advisor recommends. After completing the work, you need a postretrofit audit. Here is the actual audit specifying Appliances, Wattage and Total
