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 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 Develop commissioning requirements 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 Collaborate with "Center for Built Environment" for post occupancy evaluation of comfort and behavior Paul Delaney 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.
