Energy Audit Services & Assessments

To provide our clients with the information they need to make smart decisions with their energy efficiency initiatives, we offer a variety of different levels of audits and assessments to meet nearly every requirement – from a lighting only audit, to a DOE Energy Star Benchmarking to compressed air studies, or a specific assessment of process equipment.

Our Services & Assessments

Interior and Exterior Lighting Audits

If your company qualifies, Worldwide Energy will do a complete lighting audit of your facility, and develop a custom retrofit plan to upgrade everything to energy saving LEDs.

DOE Benchmarking

We will compare the measured performance of your facility against established norms, with the goal of informing and motivating performance improvement.

ASHRAE Level 1, 2, and 3 Audits

American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) outlines three different levels of energy audits.

Compressed Air studies

Applying best energy management practices and purchasing energy-efficient equipment can lead to significant savings in compressed air systems.

Energy Modeling

Digital modeling of a building structure simulates all aspects of energy use within the building. The systems are modeled using data gained from a building audit. This is the assurance that the digital model is accurate and can be used confidently.

Commissioning, Retro-Commissioning, Re Commissioning

From new buildings, existing buildings or commissioning a building that has already been commissioned, our process improves a building’s operations and maintenance (O&M) procedures to enhance overall building performance.

Mechanical Assessments

The evaluation about energy consumption status, energy consumption processes and energy efficiency of the system. As the premise of reducing the system's energy consumption and improving energy efficiency.

ENERGY STAR Benchmarking and Certification

ENERGY STAR certified buildings and plants meet strict energy performance standards set by EPA. They use less energy, are less expensive to operate, and cause fewer greenhouse gas emissions than their peers. Starting with the first ENERGY STAR certified building in 1999, tens of thousands of buildings and plants across America have already earned EPA’s ENERGY STAR for superior energy performance.

Both tools calculate a 1 to 100 ENERGY STAR score. Facilities that score a 75 or higher are eligible to apply for ENERGY STAR certification. Before facilities can earn the ENERGY STAR, a professional engineer or registered architect must verify that the information contained within the certification application is accurate

Types of Energy Audits

Level 1

  • Brief on-site survey of the building
  • Savings and cost analysis of low-cost/no-cost Energy Conservation Measures (ECMs)
  • Identification of potential capital improvements meriting further consideration

Level 2

  • More detailed building survey
  • Breakdown of energy use
  • Savings and cost analysis of all ECMs
  • Identification of ECMs requiring more thorough data collection and analysis

Level 3

  • Attention to capital-intensive projects identified during the Level 2 audit
  • More detailed field analysis
  • More rigorous engineering analysis
  • Cost and savings calculations with a high level of accuracy

Energy Modeling

Digital modeling of a building structure simulates all aspects of energy use within the building. The model is built based on current building plans. The existing lighting and mechanical systems are modeled using data gained from a building audit. The model provides virtual visual models of the building and its floor plans. Operating cost of various options is based on local weather data and is run for each hour of a typical year.
The base model (current building layout use and systems) is calibrated until the model matches actual utility bill for the past two years (provided by you). This is the assurance that the digital model is accurate and can be used confidently.

Digital energy modeling of the facility will:

  • Determine actual heating and cooling loads for the building.
  • Determine the proper sizing of boiler and condensing units needed to meet those loads.
  • Allow for evaluation of various scenarios of Energy Conservation Measures (ECMs) for the building.
  • Determine the energy savings resulting from the various ECMs

Building commissioning

Commissioning ensures that a new building operates initially as the designer and owner intended and that building staff are prepared to operate and maintain its systems and equipment. When a building is initially commissioned it undergoes an intensive quality assurance process that begins during design and continues through construction, occupancy, and operations.


The application of the commissioning process to existing buildings. Retro-commissioning is a process that seeks to improve how building equipment and systems function together. Depending on the age of the building, retro-commissioning can often resolve problems that occurred during design or construction, or address problems that have developed throughout the building’s life. In all, retro-commissioning improves a building’s operations and maintenance (O&M) procedures to enhance overall building performance.


Another type of commissioning that occurs when a building that has already been commissioned undergoes another commissioning process. The decision to re-commission may be triggered by a change in building use or ownership, the onset of operational problems, or some other need. Ideally, a plan for re-commissioning is established as part of a new building’s original commissioning process or an existing building’s retro-commissioning process.
