NAESCO Accreditation Programs

NAESCO's voluntary Accreditation program is open to NAESCO members.  Accreditation is offered twice annually.  The Spring Accreditation process begins in January and the Fall Accreditation begins in July.

For companies participating in the full accreditation or re-accreditation process, the participation fee has been set at $5,200. Payment of the participation fee does not in any way ensure accreditation will be granted; the fee is being imposed to cover the costs of the accreditation process including the data review and reference checking by independent reviewers.

A $250 non-refundable application deposit fee is due at the time the packet request is made and will, of course, be deducted from the balance of the participation fee which should accompany your completed application. (contact for more information, an application or to arrange payment).


Accreditation Categories

NAESCO offers three categories of Accreditation for companies in the energy service business: Energy Service Company (ESCO), Energy Service Provider (ESP) and Energy Efficiency Contractor (EEC).

Energy Service Company (ESCO) 

ESCOs develop and implement turnkey, comprehensive energy efficiency projects. ESCOs offer performance-based contracts (i.e., contracts that tie the compensation of the ESCO to the energy savings generated by the project) as a significant part of their business. To gain accreditation, ESCOs must demonstrate the technical and managerial competence to design and implement projects involving multiple technologies, including:

  • Lighting
  • Motors and Drives
  • HVAC Systems
  • Control Systems
  • Building Envelope Improvements

ESCOs must also demonstrate the ability to provide the full range of services required for a comprehensive energy efficiency project, including:

  • Energy Audits
  • Design Engineering
  • Providing or Arranging Project Financing
  • Construction Management
  • Commissioning
  • Operations and Maintenance of Energy Efficiency Technologies
  • Verifying Energy Savings

Energy Service Provider (ESP)  

ESPs in most instances will offer all of the services offered by ESCOs (see above), and additionally offer energy supply options. These options can include:

  • Development and implementation of build/own/operate distributed generation, cogeneration or combined heat and power (CHP) projects;
  • Arrangement of firm contracting of energy supply.

Energy Efficiency Contractor (EEC) 

EECs offer some, but not all, of the services of an ESCO (see above). EECs typically concentrate on one energy efficiency measure (e.g., lighting) or one type of service (e.g., engineering or project management), but can offer multiple measures or services. EECs typically work as subcontractors to ESCOs or ESPs.

NAESCO Accreditation

What NAESCO Accreditation is Not

There are certain things that accreditation does not mean. It does not mean that NAESCO certifies either expressly or by implication: that any accredited company's customer(s) will, in fact, realize cost savings by that company; or that any accredited company has any particular level of financial strength or viability.

Featured Accredited Member

CTS Group has provided healthy, safe and energy efficient infrastructures and facilities since 2000, and has been NAESCO accredited since 2009. Our turnkey project implementation process begins with extensive review of existing structures and systems, development of a holistic approach to address identified needs and implementation of improvements with guaranteed savings and costs, without change orders.  Aging and inefficient systems and facilities are transformed into ones that will be viable for years to come, operating more efficiently while providing comfortable, safe, and productive environments.   The result is energy efficient and fiscally responsible projects which are designed to reap rewards far below the bottom line.

“NAESCO accreditation is like the UL stamp of approval for customers giving them the comfort of knowing they are working with a company of integrity and one that has met the rigorous standards and requirements necessary to achieve accreditation.  We are proud to be a part of the NAESCO organization and are dedicated to continuing the work of energy efficiency through high standards of quality and integrity,” Scott Ririe, CTS Group Co-Founder.

In south central Missouri, Laclede County’s 1924 courthouse was rebuilt in 1998 with traditional rooftop air handling units.  Even though the system had been updated, utility costs were extremely high.  Through our holistic approach CTS was able to develop an improvement plan that would be paid for in annual energy savings alone of $297,656 decreasing utility costs from $4.51 to $1.82 per square foot.  Factoring in annual operations and maintenance savings at a very conservative level of $45,238 resulted in immediate positive cash flow.
