Type I Energy Audit
This audit consists of performing a walk-thu inspection of the facility to identify maintenance, operational or deficient equipment issues and to also identify areas which need further detailed evaluation. The focus is on energy savings opportunities, and is based on the existing condition of the facility.
The audit is primarily a visual inspection of operational procedures in the facility. An attempt to observe all major energy consumers within the building will be made.
The audit itself takes anywhere from ½ to 1 day to complete. The subsequent report (approximately 1-2 weeks following the audit) is a guideline for the company documenting the areas of the facility which could benefit from upgrades or improvements. The report does not detail what the energy usage is nor does it list the amount of savings that the particular company would realize. The report is intended to be used as a tool to point out the areas of energy usage which should be investigated and why.
The cost is $1,500 plus travel expenses to the client site for the audit and for the report read-out.
For large facilities, this price could increase depending on the time required for the audit.
Type II Energy Audit
This audit begins with an analysis of the utility bills for the previous 2-3 years. Then an inspection of the facility is performed. Monitoring / metering / testing are done in order to determine the precise usage of equipment as well as actual energy consumption and losses in various areas.
Detailed analysis is frequently done on items such as:
- Lighting (including levels, replacement options, sensors, etc)
- Air compressors (systems analysis and leak detection)
- HVAC systems
- Building Envelope
- Large Motor operation
- Other wastes
To do the analysis, the typical tools used include:
- Thermal Imaging cameras
- Ultrasonic Leak Detectors
- Flue gas analyzers
- Light level detection
- Data loggers for long term data collection
The report generated consists of economic calculations of current state usage and future state energy / dollar savings for a list of recommended improvements. The analysis takes into account any planned expansions or changes to the operation of the facility. Options for improvements will be provided and a recommended selection will be discussed.
The report takes about 2 to 3 weeks to complete following the audit. The report will list energy savings opportunities that include:
- Recommended changes to best practices
- Standard improvements with known energy savings
- Capital intensive changes that may require more/extensive research prior to commitment (potential economic impacts may or may not be included in this report).
- The simple payback is not normally included because quotes for equipment, labor, and maintenance have not been obtained under this audit. If quotes are available, then simple payback will be included.
The cost of a Type II Energy Audit is based upon one full day of auditing in an average sized facility. A large complex operation could require additional time so please let the client know that this price is limited to the above time in plant.
The cost is $4,950 plus travel expenses to the client site for the audit and for the report read-out. For very large facilities, this could go up depending on the time required for the audit.
Type III Energy Audit
This audit begins with a Type II Energy Audit. All of the investigation and analysis of the Type II Energy Audit is performed and the report is delivered.
At this point, the company being audited will need to decide which energy saving project(s) they wish to implement.
Missouri Enterprise will assist in developing the RFP which the company will use to obtain quotes for the implementation and installation of the improvement. Missouri Enterprise can assist in obtaining quotes from outside vendors if requested, or search for vendors if none are known.
Concurrently to obtaining quotes, the specific areas of the plant which will be effected by the new project are given a very detailed audit and documentation of existing conditions. If needed, the audit can go as far as to add additional sub-meters to areas of the facility to capture usage data. Data loggers on specific equipment may be utilized again. In some cases, computer modeling may be used to calculate precise savings.
Once the quotes are obtained, Missouri Enterprise will work with the company as needed to select a vendor. Missouri Enterprise will participate in the installation by confirming that the materials and installation are the correct and most efficient available.
Once the project is complete, a second analysis of the areas effected will be performed. This secondary analysis (or sub-audit) will confirm the expected savings by documenting the true savings realized by the project.
A final report with all information will be delivered to the company at the completion of the project.
It is not possible to determine the length of a Type III Energy Audit until the project is defined. Additionally, the project length depends on subcontractors and installers. Estimates will be given at the start of the project.
The simple payback is typically included in the final report since true payback and expenses will be known.
The cost of a Type III Energy Audit is dependent on the project(s) undertaken, the information requested by the company and the total amount of assistance provided by Missouri Enterprise.
