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.

Put Numbers on the Performance Path

Wondering how much a JA5 OCST is actually worth on your project? Use the Title 24 JA5 OCST Savings Calculator to estimate avoided PV, battery storage, and HVAC interface CAPEX based on your unit count, conditioned floor area, and California climate zone. It auto-sizes the mandatory PV and battery baselines per §150.1(c)14, applies CEC default reduction bands, and lets you layer in SEER2/HSPF2 equipment-efficiency credits when you've picked specific ductless models. Outputs are shown total, per unit, and per square foot, with a low/base/high sensitivity table so you can quote a range with confidence.

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

Solution | Flair Puck + Bridge
