4. BPA Residential Pipeline Highlights* 4 Technology and Application R&DLab Early Field Test Early Program Development *Program Deployment CO2 HPWH (TIP 292) Assess performance at 4 field sites. Final report December 2015. UL listed product expected in November. Production model will be tested to confirm performance and installation guidance will be provided. Further field tests probable. 2016- 2017 BPA Qualified 2016 target.Possible UES measure when sufficient data is collected. 2017+. Combined Space and Water Heating for Residential New Construction w/ CO 2 HPWH (TIP326) Assess performance in ten new homes. Final report in 2017. Lab testing of the combined system at Cascade. Further field tests probable. 2016- 2017 BPA Qualified 2017 target, depending on project results. Possible UES measure when sufficient data is collected. 2017+ Combined Space and H2O Heating for Retrofits, including DR (trad refrigerants and CO2)(TIP338) Lab and field test in PNNL homes. Field test performance in at least 5 locations. Final report 2017. Further field tests probable. 2016- 2017 BPA Qualified 2018 target, depending on project results. Possible UES measure when sufficient data is collected. 2017-2018+ CO2HPWH w DR (TIP 302) Completed testing in PNNL lab homes. Final report available soon. TBD Potential to add DR value to cost-effectiveness calculation for CO2 HPWH, but no separate DR measure. * Timelines are estimates
