Agenda

1. The role that C&S can play in expanding DR2. State of the Union on DR in Codes & Standards• Appliances• Building Codes

3. CA perspective: DR code triggers4. Call to Action: Opportunities for stakeholder

involvement to expand DR/ADR practices

Energy Solutions | DR and C&S Integration 3

Increasing interest in scaling up demand response and the role for C&S• “The time seems to be nigh for

demand response and I think the pressure on all of us is increasing to make it work at a scale that hasn’t been done in the past.”

• “…maybe the way [DR-enabled products] get developed is through appliance standards … or … building standards”

Code can enable participation in DR

Code can help standardize practices

What can code do?

It primes the market for broader participation

It does not mandate participation

Energy Solutions | DR and C&S Integration 5

C&S can operate in parallel with voluntary efforts to help build the market

(as opposed to a hand off)

STATE OF THE UNION ON DEMAND RESPONSE IN VOLUNTARY & MANDATORY CODE

Mandatory appliance standards have yet to incorporate DR; voluntary programs can push the market

Mandatory Can address smart grid if leads to “demonstrable” energy savings.

Voluntary Refrigerators, Freezers, Clothes Dryers – 5% credit/allowance

Anticipated Shift to

mandatory requirements with

uptake of “Green” Code.

Green codes are getting greener… and are increasingly adopted as mandatory

Voluntary Reach Codes will continue to prime code

Green building codes continue to expand incorporation of DR measures

DR Provisions primarily focus on HVAC and lightingCode Body Measures

ASHRAE 189.1

• ADR capable to drop load by > 10 % of projected peak; standby power cannot be used

IgCC • A jurisdiction can elect to require ADR capable of reducing HVAC by > 10% and lighting by > 15%

LEED • LEED Credit given to buildings that are ADR capable of dropping load by > 10 % of projected peak

CA Title 24

2008 2013 2016 – CONCEPT ONLY

• Non-res lighting: DR capability to drop 15% light load for retail >50,000 ft2

• Non-res HVAC: DR/ADR capability for DDC (

• Large Electronic Message Centers >15kW

• Non-res lighting: DR capability to drop 15% light load for all comm >10,000 ft2

• Non-res HVAC: DR/ADR capable thermostats required for buildings w/o DDC

• Res HVAC: compliance option to use DR capable thermostat

• Res: DR/ADR circuitry for 220V load

• Non-Res: DR/ADR circuitry for fork-lift charging

• Res HVAC: mandatory DR/ADR capable thermostats

TRIGGERS, BARRIERS, & OPPORTUNITIES

Energy Solutions - Standards Coordination 12

California is well positioned to adopt DR measures into code... may not be the case for other states

Loading order dictates DR before new generation

Large number of customers on Time-of-Use (TOU) rates

Title 24 cost-effectiveness evaluated using Time Dependent Valuation (TDV)

Utility ADR programs are priming code and serving to build customer confidence around DR & ADR

Advanced metering systems and protocols in place for administering events

Regulatory Triggers

Market Trigger

Technology Trigger

13

One of the largest barriers is in mitigating fear, uncertainty, and doubt (FUD)

• Title 24 - 2008 Communicating Thermostat DR Debacle– Public misinterpretation of code requirement– Codes is/will continue to be written to enable

(NOT require) DR participation

Successful participation of DR/ADR practices is dependent on stakeholder involvement

across several facets

14

Stakeholder Action

Industry, Utilities, Regulators Establish uniform protocols and terminology for DR/ADR

USGBC, ASHRAE, ICC, State Energy Commissions, Utilities

Identify new and expand upon existing DR measures

Industry, Utilities Enhance technical capacity of appliances, building equipment, and metering systems

Utilities, NGOs, Customers Reduce FUD barriers through educational programs and participation in DR

Utilities, NGOs, RegulatorsAdvocate regulators to establish DR as a necessary mechanism for grid-load-management
