Types of Audits

Green Energy Engineering, Inc. provides a range of energy audits that fits your needs from no charge / complimentary to comprehensive.  The types of audits and typical prices are as follows.

No charge – find your electric bills, natural gas bills, fuel oil bills, a description of your facility, and the air conditioned (or heated), square footage and give us a call for a free five-minute phone assessment of your facility.


$1,000 – one day walk through of facilities in the Tampa Bay, (Florida, USA) area. 

Once you are convinced from the free phone assessment, that your facility is consuming more energy than similar facilities around the country, let us provide you a one-day walk through of your specific site.  Our trained, licensed, and certified Professional Engineer will personally walk your plant and provide you with a written letter outlining energy saving ideas.  Provide the engineer with three years of fuel invoices (simply copy the monthly bills) and a plot plan of your facility and he will do the rest.

$1,000 per day plus expenses – one day walk through of facilities anywhere in the world.

$5,000 to $25,000 plus expenses - for one week of detailed data gathering at your facilities anywhere in the world. 

This type of energy audit may take an additional two to six weeks to compile the report, after the one week onsite visit.  The report will include historical energy use and costs along with future projections of the status quo and possible energy saving options.  Energy savings options will be developed to the feasibility level and include a capital cost estimate, estimated savings, projected cash flow, rate of return, payback period, and net present worth.  Provide the engineer with three to five years of fuel invoices (simply copy the monthly bills) and a plot plan of your facility.  While at the site the engineer will need to review other drawings, equipment specifications, and performance data and make copies of same.  The engineer (or someone on the plant staff) will take photos of specific equipment and possible construction areas.  It is expected that the plant staff would provide a knowledgeable guide with a master key to allow inspection of all areas of the facility.

$50,000 - $? plus expenses -  for a full investment grade technical energy audit anywhere in the world. 

This energy audit will require several weeks at the plant site and copies of possibly hundreds of drawings, equipment specifications, and performance data.  These audits require three plus months to perform and will involve several onsite meetings with the client after the initial data gathering site visit.  This audit is built upon a comprehensive and detailed energy simulation model like Trane Trace 700, DOE-2, EnergyPlus, or BLAST.  Five years of monthly purchased energy invoices are required along with detailed drawings and measurements of your specific facility.  The computer model provides hourly simulation of your energy use and will be calibrated to provide at least a plus or minus 10% of historical energy use data based on historical weather data base.  Once the model is calibrated and agreed to, Facility Improvement Measures (FIMs) will be coded and run in the computer simulation.  Results in both a cascaded and un-cascaded format will be provided and reviewed with the client over a three or more month period.  The final report is typically 2,000 pages in length and exceeds an investment quality technical energy analysis.
Facility may include: pulp mills, chemical plants, oil refineries, manufacturing plants, utility power generators, industrial facilities, large commercial factories, college campus, government buildings, schools, high rise buildings, etc.
Feasibility level is defined as plus or minus 50% cost estimate and expected savings based on historical energy costs rate increases and a single escalation factor.
