Facility Energy Auditing

An energy audit is like a medical check-up for your building. You wouldn’t trust the care and well being of your body to an untrained person, and you shouldn’t trust the evaluation of your building to an inexperienced engineer.

Our energy engineers have audited more than 150 million square feet of buildings. A successful energy project starts with a comprehensive energy audit. We pride ourselves on only using experienced engineers for our audits because we understand that it is critical that the person doing the audit doesn’t just check boxes and record equipment model and serial numbers. They need to understand the complexity of buildings and systems and how they work in order to identify the best opportunities.

GEI’s audit experience ranges from high level ASHRAE level 1 audits to full investment grade energy studies. We can deliver recommendations on all energy and water consuming systems, including HVAC equipment, fans, pumps, lighting, plumbing fixtures, kitchen equipment, and more. The goal of all of our audits is to provide our clients with the information needed  to make informed decisions about the future of their buildings and direction of their projects.

Client Benefits

  • Thorough building analysis
  • Increased understanding of building energy consumption
  • Identification of current system deficiencies
  • Development of recommended energy conservation measures (ECMs)

Energy Modeling

A building energy model is an invaluable tool in predicting the impact of changes to building systems and changes to sequences of operation. An essential part of any investment grade energy project, the model allows the identified energy conservation measure (ECM) opportunities to be operationally evaluated to determine their viability. Following a building energy audit, the collected information is used to build a model your facility or facilities. We use current and past utility bills and/or onsite data logging to allow calibration of our electronic models to the historical consumption of the building. This model can then be used to analyze different building envelope, HVAC and lighting systems to determine the most efficiency energy solutions. We analyze building systems and calculate detailed energy savings utilizing hourly, site-specific weather data. GEI uses a variety of modeling software packages including Trace 700, Carrier HAP, and eQUEST.

    In addition to modeling existing facilities, GEI has experience building energy models for LEED certification. As part of this service, GEI will complete the LEED forms necessary for EA credits, and provide recommendations to increase EA points. Our modeling expertise includes a variety of building types including educational buildings (both K-12 and higher education), public assembly facilities, industrial and manufacturing buildings, office buildings, military and judicial buildings, and technically complex spaces such as vivariums  and research facilities.

    Sample Projects

    Peninsula Regional Medical Center, Salisbury, MD
    Georgia Mountain Authority, Multiple Locations
    Sustainable Energy and Technology Center, Danville, VA

    Client Benefits

    • You will have a calibrated building model to use in on-going analyses of your building to analyze energy consumption impact of new improvements, additions, and/or modifications to the building and/or the building’s systems.
    • Aid in development of accurate system operation strategies.
    • Compare existing and alternative systems operational costs.
    • Calculate annual and lifecycle energy and cost savings for proposed ECMs.

    Utility Rate & Rebate Analysis

    Understanding how a building uses energy in relation to how a utility charges for energy for that building is a powerful tool that can be used to lower utility costs. Investigating utility tariff options in the context of historical demand and usage can often lead to substantial dollar savings, in turn allowing clients to reinvest their energy dollars in facility improvements.

    Examples include propane-air systems that allow a client to utilize an interruptible gas rate structure that results in lower gas costs.

    In addition to rate analyses, many utilities offer rebates or incentives for installing new energy efficient systems and equipment. GEI can help you understand and apply for rebates where available, and these rebates can often improve the financial viability of desired energy efficiency improvements.

    Sample Projects

    Avonlea on the River, Duluth, GA
    Atlantic Station, Atlanta, GA
    Savannah College of Art & Design, Atlanta and Savannah, GA

    Utility Rate Analysis Benefits:

    • Lower energy rates
    • Lower utility costs
    • Reduced cost of energy efficiency measures
    • Ability to reallocate operational funds to capital improvements

    Performance Contracting Support (ESCO/Utility)

    Developing an ESPC or UESC contract can be a time consuming and technical process, and numerous ESCOs and utilities rely on GEI to provide engineering support for these efforts. GEI understands the process required to develop these projects, and our energy engineers are a seamless addition to your team. From preliminary auditing and energy analysis, to system design, commissioning, and M&V services, GEI can provide the support you need to successfully complete your project.

    Some companies outsource the majority of their engineering tasks to GEI, while others pick and choose the skills needed augment their internal resources. Our goal in providing ESPC/UESC support is to make the life of your project developers easier and to ensure that your project is successful.

    Sample Projects

    Fort Greely, Delta Junction, AK
    Knox County Government, Knoxville, TN
    SCCPSS, Naval Air Station Oceana, Norfolk, VA
    University of Central Missouri, Warrensburg, MO

    ESCO/Utility Support Benefits:

    • Engineering team experienced with all phases of the project
    • Flexible resources based on individual needs
    • Small business partner
    • Highest quality engineering analysis
    • Additional resources to pursue more projects

    District Energy Plant Analysis

    Because we have an extensive background working with utilities and building owners in the development and evaluation of district energy options, our team brings a high level of expertise to clients evaluating system alternatives. GEI helps quantify the cost of district energy alternatives to allow clients to make more educated decisions regarding their facilities.

    Sample Projects

    John B. Shepherd Central Plant, Clark Atlanta University, Atlanta, GA
    Downtown Cincinnati, Cincinnati, OH
    Atlantic Station, Atlanta, GA

    District Energy Plant Analysis Benefits:

    • Provides a financial basis for central plant decision making
    • Provide a full understanding of the impact of a heating and cooling plant
    • Identifies a clear pathway to meet future goals

    Third Party Project Review

    Many building owners do not have significant experience executing performance contracts. GEI’s experience working with performance contracts and completing hundreds of  energy studies make us a great resource when you need third party review of your projects. We provide thorough and expert review of your proposed projects to ensure viability of the energy savings. Every ECM is evaluated for proper calculation methodology, proper assumptions and reasonable results. The measurement and verification protocols are also reviewed to  verify that they are fully encompassing and truly measure what is being guaranteed so that the owner is protected should the contract supplier not meet expectations.

    When the state of Georgia moved forward with its pilot ESPC project for the Department of Corrections, GEI was asked to provide the third party review. Our engineers identified areas where savings assumptions were unreasonable and advised the state on the risks and rewards of the proposed M&V plan. With our recommendations, the State and DOC were able to make an informed decision on how to best proceed with the project.

    Sample Projects

    Georgia Environmental Finance Authority’s Pilot ESPC
    Missouri State University, Springfield, MO
    Georgia Department of Corrections, multiple locations

    Third Party Review Benefits:

    • Expert review of savings calculation methodologies to ensure accuracy
    • Works toward protection for owner should the ESPC/UESC not deliver on promises
    • Empowers the owner to make informed, financially sound decisions
