California Title 24 Opportunity
The California Energy Commission (CEC) defines Occupant Controlled Smart Thermostats (OCSTs) under Title 24 JA5.
Installing Flair’s JA5-certified Puck thermostats allows builders to reduce or eliminate solar requirements under the Performance Method, cutting construction costs while improving system performance.
CEC Title 24 Basics
Title 24 mandates solar panels on most new multi-unit residential projects or allows trade-offs through energy conservation measures (ECMs), such as:
- Ductless Heat Pumps (DHPs)
- JA5-Certified OCSTs
Because solar installation can be a major cost driver, the Performance Pathway enables developers to meet energy targets through smarter HVAC and controls—reducing PV system size or eliminating it entirely.
What is an OCST?
An Occupant Controlled Smart Thermostat (OCST):
- Allows occupant control and utility demand response
- Meets JA5 standards for energy responsiveness and override capability
- Ensures real-time energy optimization
Key Requirements:
- Demand Response (DR): Must use open standards (OpenADR 2.0)
- Occupant Override: User always retains control
- Certification: Manufacturer compliance with CEC JA5
