3. Designer Unfamiliarity with VCHP Technology misapplication Technology misapplication can affect deployment Lack of education in design and construction fields on technology Unfamiliar with controls Proprietary equipment makes it hard to understand or commission Some applications are not appropriate for VRV e.g. large OSA with not many zones Engineers are designing systems around the technologies that they are more comfortable with VCHP does not fit into standard design process Not all applications of VCHP systems with simultaneous heating and cooling capability are cost effective Codes and standards were not available until recently Questionable cost effectiveness of economizers and ground coupled applications Develop designer training and outreach Lack of robust design and modeling tools Lack of performance data to validate manufacturer claims Get early copies of ASHRAE VRF Handbook Chapter, which is scheduled to be available Spring of 2012 Document operation in lab tests Develop commissioning requirements Develop best practices to ensure energy savings Daikin provides online classes (http://www.daikinac.com/commercial/trainingOverview.asp?sec=training) Develop screening tool for cost effective opportunities Collaborate with "Center for Built Environment" for post occupancy evaluation of comfort and behavior Paul Delaney Lessons learned from ASHRAE Headquarters VRF demonstration project Investigate lessons learned from Oakridge residential DHP field testing Get early copies of ASHRAE 90.1 2010 VRF mechanical tables Investigate new products and features, including US-centric controls, heat pump boilers, data center rack cooling, etc. Mike Cundiff EWEB commissioning case study TI Project 216 EPRI Lab Testing AHRI 1230 Mike Cundiff Investigate lessons learned from Energy Trust New Buildings program has provided incentives for new community college buildings in Southern Oregon, installing Mitsubishi VRFs.

4. Owner Unfamiliarity with VCHP Perception of risk, uncertain owner and user, occupant acceptance There are a lot of HVAC options in the market so this may not be perceived as the best option for a given application Unsure of system operation Owners are not familiar with the systems Lack of data and market knowledge to promote technology Uncertainty in the market about the benefits of the system over the other systems Develop best practices to ensure energy savings Develop owner training on utility incentives and VCHP benefits Lessons learned from ASHRAE Headquarters VRF demonstration project Investigate lessons learned from Oakridge residential DHP field testing Get early copies of ASHRAE 90.1 2010 VRF mechanical tables Investigate new products and features, including US-centric controls, heat pump boilers, data center rack cooling, etc. Mike Cundiff Collaborate with "Center for Built Environment" for post occupancy evaluation of comfort and behavior Paul Delaney NEEA and BOMA owner training Investigate lessons learned from Energy Trust New Buildings program has provided incentives for new community college buildings in Southern Oregon, installing Mitsubishi VRFs.

5. Lack of Information to Prioritize Measures Uncertain cost effectiveness for some applications Hard to define baselines to make comparisons Select and define highest priority measures Identify when and where designers include electric resistance heat with VRF systems Quantify savings for replacing electric heat Preliminary screening of cost effectiveness of measures Understand engineering, Installation, ownership, utility barriers Investigate savings for baselines that do not have cooling Screen for where VRF HR systems are cost-effective Evaluate top identified applications Evaluate whether the amount of VCHP refrigerant is an issue Develop cost database Verify the significance of duct losses and feasibility of M&V Identify installations where savings can be verified ASHRAE 90.1 2010 Appendix G Distribute and post EPRI VRF market studies, commissioned by BPA, when they are available Mira Vowles Mitsubishi VRF analysis based on EnergyPro model Nick Fernandez VCHP measure potential research and studies (Power plan) 5

6. Uncertain Energy Savings, Costs and Cost Effectiveness Uncertain savings Uncertain cost Unknown equipment life Incremental costs of VRF systems could be higher or lower than baseline systems Skepticism about savings and real cost/benefit ratio Condensate piping and pumps are a costly oversight Utilities can not incent if incremental cost is negative Quantify savings and costs over a specific baseline Select baseline Establish measure life Develop models to quantify savings for top priority measures Quantify non-energy benefits (O&M, gas savings, productivity due to improved comfort, etc.) to fully account for additional cost effective measures Quantify energy savings for night setback Quantify annual energy savings, benefits, costs TI Project 216 EPRI VRF HR Lab Testing Use AHRI 1230 equipment performance ratings (EER, COP, IEER) to estimate savings, including water cooled VRF system savings over air cooled VRF systems Mike Cundiff Distribute and post EPRI VRF market studies, commissioned by BPA, when they are available Mira Vowles Mitsubishi VRF analysis based on EnergyPro model Nick Fernandez Document savings trade-off for VRF HR without economizers, Paul Doppler Jim Benville Investigate lessons learned from PNNL/NEEA work to disaggregate electrical loads, and use to determine actual VRF system energy use Nick Fernandez Investigate savings and lessons learned from Corvallis Wild Life Preserve VRF system with HRV and economizers Mark Jerome Investigate new products and features, including US-centric controls, heat pump boilers, data center rack cooling, etc. Mike Cundiff Investigate life of Asian systems Investigate lessons learned from BC Hydro VRF office building retrofit in Vancouver; combination of modeled/measures savings.

7. M&V for Uncertain Energy Savings Existing M&V approaches like energy modeling and deemed savings are not proven for VRF systems Complex systems-hard to accurately measure and quantify savings Challenges metering commercial VCHP systems Develop high consensus M&V protocols Identify installations where savings can be verified Possible opportunity for field testing in a set of test bed commercial buildings that are being constructed in Richland, WA at PNNL's headquarters.
