Accreditation is only open to NAESCO members in good standing. NAESCO membership must be current in order to keep a firm's NAESCO accreditation.
Companies seeking NAESCO-Accredited status must apply to a committee of industry experts who are unaffiliated with any particular ESCO or any other company under consideration for accreditation, and undergo a rigorous examination of their core competencies and business practices. The committee carefully reviews the detailed documentation submitted and consults with selected customer references.
The committee looks at criteria including the following: the precise nature of the applicant's business; the range of measures and services offered to customers; the availability of a performance-based project approach; ethical business practice commitment; project engineering and design, financing, project management, operations, and maintenance capabilities; and the capability of verifying and monitoring energy cost savings.
