The Tool Lending Library (TLL) is a Public Goods funded program that loans building measurement equipment free of charge to qualified Sonoma County professionals working on short term energy efficiency projects. It also provides advice and application notes for some of the tools in the TLL. There are special considerations or borrower qualifications for most of the equipment in the TLL.
The TLL is made possible through a partnership with the Sonoma County Human Services Department. Funding was provided through a grant from the California Clean Energy Workforce Training Program for development of services to identify and train for employment opportunities in green energy occupations.
The Tool Lending Library program focuses primarily on residential projects. These tools are only made available to home performance professionals (see TLL Policy).
