Starting in June, California’s latest version of its Title 24 building code kicks in, requiring several systems come with demand response capability. Every new or retrofit thermostat, HVAC system, networked lighting controller, and building automation system in the state will come ready for two-way, automated utility-to-customer energy management. They are required to be “capable of receiving and automatically responding to at least one standards-based messaging protocol” to receive signals from utilities.
