SECTION 110.12 – MANDATORY REQUIREMENTS FOR DEMAND MANAGEMENT
Buildings, other than healthcare facilities, that install or are required to install demand responsive controls shall comply with the applicable demand responsive control requirements of Sections 110.12(a) through 110.12(e).
(a) Demand responsive controls.
1. All demand responsive controls shall be either:
A. A certified OpenADR 2.0a or OpenADR 2.0b Virtual End Node (VEN), as specified under Clause 11, Conformance, in the applicable OpenADR 2.0 Specification; or
B. Certified by the manufacturer as being capable of responding to a demand response signal from a certified OpenADR 2.0b Virtual End Node by automatically implementing the control functions requested by the Virtual End Node for the equipment it controls.
2. All demand responsive controls shall be capable of communicating with the VEN using a wired or wireless bi-directional communication pathway.
3. RESERVED
4. When communications are disabled or unavailable, all demand responsive controls shall continue to perform all other control functions provided by the control.
5. Demand responsive control thermostats shall comply with Reference Joint Appendix 5 (JA5), Technical Specifications For Occupant Controlled Smart Thermostats.
(b) Demand Responsive Zonal HVAC Controls.
Nonresidential HVAC systems with DDC to the Zone level shall be programmed to allow centralized demand shed for noncritical zones as follows:
1. The controls shall have a capability to remotely increase the operating cooling temperature set points by 4 degrees or more in all noncritical 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 decrease the operating heating temperature set points by 4 degrees or more in all noncritical 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 noncritical 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 increase, decrease, and reset.
5. The controls shall have the following features
A. Disabled. Disabled by authorized facility operators; and
B. Manual control. Manual control by authorized facility operators to allow adjustment of heating and cooling set points globally from a single point in the EMCS; and
C. Automatic Demand Shed Control. Upon receipt of a demand response signal, the space- conditioning systems shall conduct a centralized demand shed, as specified in Sections 110.12(b)1 and 110.12(b)2, for noncritical zones during the demand response period.
(c) Demand Responsive Lighting Controls.
Buildings with nonresidential lighting systems having a total installed lighting power of 4,000 watts or greater that is subject to the requirements of Section 130.1(b) shall install controls that are capable of automatically reducing lighting power in response to a Demand Response Signal.
1. For compliance testing, the lighting controls shall demonstrate a 15 percent or greater reduction in lighting power as described in NA7.6.3. The controls may provide additional demand responsive functions or abilities.
2. For buildings where demand response controls are required, demand responsive controls shall control the general lighting that is subject to the requirements of Section 130.1(b) and may control additional lighting.
3. General lighting shall be reduced in a manner consistent with the uniform level of illumination requirements in TABLE 130.1-A.
EXCEPTION to Section 110.12(c): Spaces where a health or life safety statute, ordinance, or regulation does not permit the general lighting to be reduced are not required to install demand responsive controls and do not count toward the 4,000 watt threshold.
(d) Demand Responsive Electronic Message Center Control.
Controls for electronic message centers greater than 15 kW shall be capable of reducing the lighting power by a minimum of 30 percent when receiving a demand response signal.
EXCEPTION to Section 110.12(d): Electronic message centers that are not permitted by a health or life safety statute, ordinance, or regulation to be reduced.
(e) Demand Responsive Controlled Receptacles.
Controlled receptacles in buildings shall be capable of automatically turning off all loads connected to the receptacle in response to a demand response signal.
Exception 1 to Section 110.12(e): Buildings not required to have demand responsive lighting controls.
Exception 2 to Section 110.12(e): Spaces where a health or life safety statute, ordinance, or regulation does not permit the receptacles to be automatically controlled.
