This topic did not generate much discussion. At least one stakeholder indicated that this was not a good candidate for EPA sponsored ETV performance verification. It was felt that government agencies focused on agricultural issues would be more effective and credible at increasing the penetration of these technologies. These technologies will not be actively pursued by the Center. Again, there was not much discussion on this topic.
Geothermal heat pumps.
Although not discussed much, support for examining these systems was voiced by one stakeholder member. Gas-fired residential heat pumps. Although not discussed much, support for examining these systems was voiced by one stakeholder member. Based on comments from several stakeholders and one expert presenter, technology options associated with this area are typically implemented by the semi-conductor manufacturers, and may not require ETV services. It was suggested that PFC mitigation in the aluminum and microelectronics industries were likely not good candidates for ETV verification.
