10 Southern California Gas Company Boiler Temperature Reset Controller Abdullah Ahmed Technical Development Manager September 18, 2014 Salt Lake City, UT

11 Boiler Temperature Reset Controller Drivers Energy efficiency; Multi-family stakeholder request Heating fuel costs Technology/Product Retrofit controller for boiler combo (water and space heating) systems Modulates boiler firing and staging based on season, OSA temperature Project Genesis Vendor approached SoCalGas ETP about new technology Hydronic boiler systems are underserved market (2,000+ units) Simple & eloquent innovation Prior experience with vendor Combo (Domestic HW & Hydronic Space Heating) Boiler, Typ. 1.5 MMBtu/hr 2

12 Project Screening Criteria Criteria Impact Result Energy Savings Installed Cost Economic Payback System Performance System Durability Critical: a deal-breaker if energy savings are not adequate Important: unit needs to be affordable Critical: customers require reasonable payback Important: customer comfort cannot be compromised Important: system performance needs to hold up over time Key factor in customer value proposition Key factor in customer value proposition Payback needs to be in the range of 2-3 years Most customers can tolerate slightly lower hot water temperature Durability appears to be reasonable. Operator education is the key. 3

13 The Approach Phase : (4) unit test at (2) apartment complexes. Phase : 30 unit test at (8) apartment complexes. Phase : Competitive assessment Continue phase 2 testing, collect data Develop resource program options Work Paper >> EE Rebates 3rd Party Performance Contracting Direct Install Standard Analog Controller Dual Setpoint Digital Controller 4

14 Assessment Results/Benefits Standard boiler controllers typically set to highest water temperature setting (~130ºF) Analog devices adjust water temperature according to outside air temperature New digital controller more precisely controls burner, average 19% natural gas energy savings Payback opportunity: 3-5 years System appears to be stable, reliable, ready for launch Vendor added wireless feature as a result of ETP project Next step: developing resource program features 5

16 SDG&E Multi-Vendor RTU Retrofit Controllers Study Kate Zeng SDG&E Emerging Technologies Program September 18, 2014 Salt Lake City, UT

17 Technology Overview Advanced rooftop unit controller retrofits convert single speed HVAC systems to variable speed systems that can optimize performance for varying loads. 2

18 Advanced Rooftop Unit Controller Retrofit: The Potential RTUs predominantly in retail & medium office (PNNL) Combined HVAC in SDG&E region is 514 GWh (CEUS) Assume 40% HVAC energy use savings Assume 10% market penetration Energy savings potential in SDG&E region is about 20 GWh Note: These assumptions are for illustration purposes only and not meant to suggest that these level of savings or market penetration can or will be accomplished. 3

19 Program Readiness Questions Technical readiness How does the system work? What are the energy savings? What might cause variation in energy savings? Are there opportunities to improve the technology? Market readiness What are the applicable building codes? How are these products bought, sold, and installed? 4

20 Approach Test site was a small commercial building in San Diego Install one instance each of four RTU retrofit controllers Measure energy savings over test period and estimate annual savings ARC Features Compressor cycling Compressor speed control Compressor short cycling awareness Compressor supply fan speed control Economizer control DCV FDD Applicable to packaged units Applicable to split systems Reduces energy consumption Reduces demand 5

21 Simple Payback Period Results Cost (for one device for this project) Annual Savings % Annual Savings per one device on 7.5 ton unit [kwh] Assumed blended rate [$/kwh] Simple Payback Period [years] A $3,800 26% 2,700 $ ¹ B $2,000 N/A² N/A² $0.08 N/A² C $950 13% 2,860³ $ D $8,500 N/A⁴ N/A⁴ $0.08 N/A⁴ 1. Payback period would ve been better if zone HVAC load were higher. 2. No useable data due to unforeseen installation issues. 3. Unusually high. Likely due to large area of unobstructed west facing glass. 4. Cooling savings of 27%. Insufficient heating data to calculate annual savings or payback period. 6

22 Conclusions & Recommendations Conclusions Energy savings can be substantial. RTU operation may also be improved, especially if the existing RTU is oversized or the supply diffusers are drafty. These products add complexity to an existing RTU, add potential points of failure, and may increase required RTU maintenance. A RTU must first be in decent condition before the product is installed or it will be difficult to commission. Recommendations RTU should have suitable qualities (e.g. 7.5 tons or greater, well maintained but conventional components, less than about 5 years old). Building should have suitable qualities (e.g. multiple RTUs, BMS in good condition). A la carte incentives for DCV, ADEC, and Supply Fan VFD retrofit through Energy Efficiency Business Rebates or Incentive (EEBR, EEBR). 7

31 Advanced Lighting Controls, Comprehensive Retrofits Substantial savings potential Customer satisfaction Comprehensive Retrofits Lighting redesign Higher efficiency lamps Task tuning Motion sensors Daylight sensors OpenADR enabled Controllable through user-friendly GUI Built-in energy savings tracking 2

32 Advanced Lighting Controls Research Questions What level of savings is feasible? What portion of savings is from lights and what portion from controls? How well does the on-board monitoring corroborate results? How easy are these to install? Commission? What applications make sense to target? What are the payback ranges? How do the systems perform? Are they robust? Easy to troubleshoot? How much contractor training is needed? How happy are the customers with the systems? Do they address non-energy customer needs? 3

33 Advanced Lighting Controls Pilot ARRA funded through SMUD s Smart Grid Grant 3 small demos in 2011 were followed by a pilot program approach in Qualified Products List developed (10 currently on list) Trainings conducted for industry, customers 20 projects completed Savings ranged from 50 90% Payback periods <1y - >10y depending on application 4

34 Advanced Lighting Controls Benefits Pilots showed substantial savings possible 50 90% lighting energy savings, nearly half of this from the controls strategies Target customers were identified as industrial customers with high wattage applications Office applications require fixture integrated controls to reduce costs Complexity requires substantial promotion to help contractors choose this technology Program is currently being offered through SMUD custom incentives program, uptake has been slow without dedicated promotion 5
