Snohomish County Public Utilities District ({\textquotedblleft}the District{\textquotedblright} or {\textquotedblleft}Snohomish PUD{\textquotedblright}) provides electricity to about 325,000 customers in Snohomish County, Washington. The District has an incentive programs to encourage commercial customers to improve energy efficiency: the District partially reimburses the cost of approved retrofits if they provide a level of energy performance improvement that is specified by contract. In 2013 the District contracted with Lawrence Berkeley National Laboratory to provide a third-party review of the Monitoring and Verification (M\&V) practices the District uses to evaluate whether companies are meeting their contractual obligations. This work helps LBNL understand the challenges faced by real-world practitioners of M\&V of energy savings, and builds on a body of related work such as Price et al. (2013).
The District selected a typical project for which they had already performed an evaluation. The present report includes the District{\textquoteright}s original evaluation as well as LBNL{\textquoteright}s review of their approach. The review is based on the document itself; on investigation of the load data and outdoor air temperature data from the building evaluated in the document; and on phone discussions with Bill Harris of the Snohomish County Public Utilities District. We will call the building studied in the document the {\textquotedblleft}subject building,{\textquotedblright} the original Snohomish PUD report will be referred to as the {\textquotedblleft}Evaluation,{\textquotedblright} and this discussion by LBNL is called the {\textquotedblleft}Review.{\textquotedblright}
