Graboyes Efficiency Tenant LLC is a Philadelphia-based energy services company that helps create net-zero buildings by combining the groundbreaking metered energy efficiency transaction structure (MEETS) with onsite generation and ancillary grid services.

MEETS is a powerful financial tool that allows energy efficiency to be generated, bought, and sold much like electricity. The transaction structure of the MEETS concept provides building owners with a long-term, rent-paying tenant that leases the privilege of making deep energy efficiency improvements to buildings – beyond those typically attainable via conventional financing approaches. The tenant then sells the newly created efficiency to a utility company. Graboyes Efficiency Tenant is the first company in the world formed specifically to serve as such a tenant to building owners.  

Graboyes Efficiency Tenant works in collaboration with its sister companies, the architectural glazing and window installation firm Graboyes Commercial Window and Glass Solutions and the building performance firm Graboyes Smart Buildings, helping to create net-zero buildings by combining MEETS with building envelope improvements, onsite generation including building-integrated PV and roof- and ground-mounted solar PV, and ancillary grid services.

The Efficiency Tenant team cumulatively has more than 50 years of experience in energy services project development and implementation, having been involved in the design, development, construction, and operation of net-zero, passive house, and high-performance buildings throughout the United States.
