Why Climate Zone 8 Matters Here
Climate Zone 8 covers Whittier and is characterized by hot summer afternoons moderated by some coastal influence. Title 24 software accounts for this automatically, but it changes which upgrades make the most sense for your project.
Estimated from proximity to the nearest CEC reference station — we confirm the exact zone for your project's address before preparing your report.
Frequently Asked Questions

In most cases, yes — we can review an existing report and prepare a revision rather than starting from scratch, which is typically faster and less expensive than a brand-new report.
No. The Title 24 report (CF1R) is the energy design document submitted with your permit. HERS verification is a separate field inspection process — required only for certain compliance credits — performed by a certified HERS rater during construction.
