1. Through the use of nationally recognized open

communication standards, the value of installed AutoDR

infrastructure persists over time.

2. Without open standards at the facility level, risk of vendor

lock-in which reduces value of AutoDR investment.

3. Though national open standards may change or beenhanced over time, the open development process ensures

that solutions are available from many vendors and that a

low-cost or no-cost upgrade path is available to keep the

building stock up to date with the latest software patches.

1. ~ 50 companies have integrated AutoDR client software

into their products.

1. Automated Logic Corp., Honeywell, Echelon, Cisco, Tridium

and many mid-sized and smaller manufacturers of controls andcommunications equipment

2. Hardware retrofit solutions

1. Device receives signal via Internet, triggers relay contacts.

2. Existing EMCS initiates demand shed strategies.

3. Software solutions

1. EMCS receives signal via Internet, triggers software points

Sect i on 101 ( b ) D ef i n i t i ons

DEMAND RESPONSE is short-term changes in electric usage by end-use customers from their

normal consumption patterns in response to changes in the price of electricity over time, or to

incentive payments designed to induce lower electricity use at times of high wholesale market

prices or when system reliability is jeopardized.

DEMAND RESPONSE PERIOD is a period of time during which electricity loads are curtailed in

response to a demand response signal.

DEMAND RESPONSE SIGNAL is a signal sent by the local utility, Independent System Operator(ISO), or designated curtailment service provider or aggregator indicating a price or a request to

their customers to curtail electricity consumption for a limited time period.

DEMAND RESPONSIVE CONTROL is a control that is capable of receiving and automatically

responding to a demand response signal sent via a third-party network or device

Sect i on 101 ( b ) D ef i n i t i ons (continuted)

ENERGY MANAGEMENT CONTROL SYSTEM (EMCS) is often a computerized control system

designed to regulate the energy consumption of a building by controlling the operation of energy

consuming systems, such as the heating, ventilation and air conditioning (HVAC), lighting and

water heating systems. The EMCS is also capable of monitoring environmental and systemloads, and adjusting HVAC operations in order to optimize energy usage and respond to demand

response signals. (See DEMAND RESPONSE SIGNAL)

SECTION 122 REQUIRED CONTROLS FOR SPACE-CONDITIONING SYSTEMS

(h) Automatic Demand Shed Controls. HVAC systems with DDC to the Zone level shall be programmed to

allow centralized demand shed for non-critical zones as follows:

1. The controls shall have a capability to remotely setup the operating cooling temperature set points by 4 degrees

or more in all non-critical zones on signal from a centralized contact or software point within an Energy

Management Control System (EMCS).

2. The controls shall have a capability to remotely setdown the operating heating temperature set points by 4

degrees or more in all non critical zones on signal from a centralized contact or software point within an EMCS.

3. The controls shall have capabilities to remotely reset the temperatures in all non critical zones to original

operating levels on signal from a centralized contact or software point within an EMCS.

4. The controls shall be programmed to provide an adjustable rate of change for the temperature setup and reset.

5. . The Automatic shed controls shall be capable of the following modes:

i) Disabled by authorized facility operators.

ii) Manual control by authorized facility operators. Allows operators to adjust heating and cooling

setpoints globally throughout the facility from a single point in the EMCS.

iii) Automatic Demand Shed Control. Upon receipt of a remote DEMAND RESPONSE SIGNAL, the

space conditioning-systems shall conduct a centralized demand shed for non-critical zones during the

DEMAND RESPONSE PERIOD, as described in 122 (h) 1. and 122 (h) 2. above.

(proposed) SECTION 135

DEMAND RESPONSE SIGNAL. Demand response signals shall conform to a communications

standard from Table 4-1 in NIST Framework and Roadmap for Smart Grid Interoperability

Standards.

Future compliance manual language:

Acceptable standards include OpenADR (Open Automated Demand Response) and ZigBee Smart

Energy Profile.

OpenADR is defined by the following standards development organization:

Organization for the Advancement of Structured Information Standards (OASIS), Energy

Interoperation Technical Committee.
