Reach out to us: [sales@flair.co](mailto:sales@flair.co) ## California Title 24 Opportunity The California Energy Commission (CEC) defines Occupant Controlled Smart Thermostats (OCSTs) under [Title 24 JA5](https://www.energy.ca.gov/rules-and-regulations/building-energy-efficiency/manufacturer-certification-building-equipment/ocst). 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**](/content/pages/title-24-calculator "Title 24 Calculator"/index.html) 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.
