4 Current Code Requirements 4 Standard Design for Hydronic Space Heating Res hydronic heating system compared to central furnace with duct loss Air Dis Table R3-1 Summary of Standard Design HVAC System Proposed Design Standard Design Heating System Cooling System Heating System Cooling System Detailed Specifications Through-the-wall heat pump Gas wall furnace with our without ducts and/or circulation fan Any other electric heat including electric resistance, water source heat pump, etc. Any Any Same equipment as proposed design with no air distribution ducts Same equipment as proposed design with no air distribution ducts Split system AC with air distribution ducts Split system heat pump with air distribution ducts All other gas heating Any Split system air conditioner with gas furnace and air distribution ducts. Equipment efficiency determined by CEC Appliance Efficiency Regulations SEER per Package D Verified refrigerant charge (prescriptive requirement) No credit for sizing No credit for cooling coil airflow No credit for reduced fan power Note: The standard design cooling system is also used for the proposed design if the proposed design has no air conditioning

5 Current Code Requirements Standard Design for Hydronic Space Heating N Res hydronic heating system compared to 4-pipes fan coil system with duct loss 5

6 Current Code Requirements 6 VRF technologies not recognized by ACMs Treated as heat pump with minimum compliance efficiency Waived from federal testing requirements

7 Typical Practice 7 Hydronic heating, including combined hydronic heating, are used in MF and in nonres. Buildings (18% in Low Rise, 7% in High Rise according to PG&E California Multi-Family New Homes program) DHW and hydronic system control technologies are commonly used VRF technologies have relatively low market share; they have high part-load efficiencies and have no duct losses

8 Code Change Proposal #1 8 Distribution Pipe Heat Loss Hourly pipe heat loss calculation Consistency DHW and Hydronics Space Heating Algorithms for controls Temperature modulation Flow variation Default distribution system layout Hydronic system fuel consumption calculation

9 Data / Findings PIER DHW Research 9 In-depth understanding of central DHW distribution system based on field performance study of 30+ MF buildings Monitoring of HW & CW flows, temperatures, and pressures; gas flows System controls study and cool down tests System heat balance and energy flow analysis DHW recirculation loop modeling 30% Water Heater Losses Recirculation Loop Losses 30% Branch Losses* Distribution Losses End-Use Energy Include pipe inside and outside of dwelling units

10 Data / Findings Pipe Heat Loss Model 10 System model includes two heat transfer modes with consideration of transition Pipe heat transfer with HW flow UA, water temp & flow, ambient temp Pipe without HW flow - cool down UA and pipe/water thermal capacity

11 Data / Findings Model Validation Based on actual building DHW recirculation loop configurations Compare modeled vs. measured HWR Temp, and energy losses

13 Specifics of Code Change Proposals Distribution pipe heat loss Existing DHW ACM 13 Hourly Adjusted Recovery Load Hourly Standard End Use Distribution Loss Multiplier Solar Savings Multiplier Hourly Recirculation Distri. Loss Hourly Jacket Loss Implement monthly variation Inside dwelling unit: Proposed Improvement DLM k =1 + (SDLM k -1)*DSM k DSM k =1 for MF SSM k should be applied to HRDL k as well; however, it depends on how SSF is rated Recirculation Loop Plumbing layout based on building geometry HW Draw patterns; or HW flow rates for hydronic heating HW temp: 135F for HW; vary for hydronic heating & Control Branch Depend on HSEU k should be a multiplier to HSEU k Modify DLM k to include heat loss from branches outside of dwelling unit

14 Specifics of Code Change Proposals Proposed Recirculation Distribution Pipe Heat Loss Assess hourly average pipe temperature to calculate heat loss - Replace the table of UL with explicit calculation 14 Hourly average water temperature for pipe section, n Hourly ambient temperature for pipe section, n Average pipe temperature is weighted between two modes, which depend on control schedule Weighting factor depending on control schedule Average water temperature during pump-off period Each control strategy has a 24-hour schedule Average water temperature during pump-on period

15 Specifics of Code Change Proposals Continuous Pumping Hour p Pump off Time T S T S With cont. monitoring p TIMER Pump off Time T S p DEMAND CONTROL Pump off Time T S p TEMPERATURE MODULATION Pump off Time T S T S With cont. monitoring

16 Specifics of Code Change Proposals Current ACM requires user input of pipe length for three pipe sections Proposed changes Supply and return each has three sections Unconditioned, conditioned, (semi-conditioned), underground, Return pipes behave dramatically different from supply pipes under controls ACM generate default system layout to check/adjust user input (details to be discussed after ACM algorithms) 16 Boiler Room Supply Return n=1 n=2 n=3 n=6 n=5 n=4 CA Hydronics Utilities 2013 heating Title and 24 Stakeholder Central DHW Meeting ACM update for Proposed Code Changes 12/13/2010
