"Sampling is intended to provide certification that a group of new homes meets a particular threshold such as ENERGY STAR, energy code compliance, or qualification for an energy efficiency lending program."
Every home within a given sample set shall be assigned the HERS Index Score as determined by the worst-case analysis and threshold specification for the floor plan for that home
Sampling controls may be applied to any sample set of homes within the same subdivision, community or metropolitan area and climate zone:
Depending on the energy program being used, we will follow a checklist to inspect certain items for compliance.

Once first 3 has been completed, sampling can begin.
Homes are put into sample sets (see above) based on start date. The max number of homes in a batch is 7.
Sampling is at a rate of 1 home tested out of 7 homes.
Each item on the field checklist is inspected based on phases of inspection.
