Phase I: Determination of Unit Energy Savings and Measure Cost

The Ground Source Heat Pump subcommittee guided the work of the RTF contractor Ecotope as they developed draft recommendations for the update of the RTF deemed measures and presented findings and recommendations. The recommendation was determined to involve one of the following outcomes: a) continued use of the current measure definitions, input assumptions, and analysis methods, with revisions made only to the cost-effectiveness analysis; b) revisions to one or more measure definitions, input assumptions, or analysis methods, and update to the cost-effectiveness analysis; or c) re-classification of the measure as not deemed.


Phase II: Technical Specifications

At the August 2, 2011 RTF meeting, the RTF adopted final unit energy savings and costs for GSHP measures (Phase 1 is now complete), and the RTF asked the GSHP subcommittee for their review of the proposed measure technical specifications (pre-existing specs) along with a public review period. The process and dates for this review are as follows:
