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.

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

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.
