Need Title 24 energy compliance documentation for your construction project?
T24 Consulting has you covered!
We use the latest open-source software to quickly and accurately model, analyze, and document your building’s performance - saving you time, money, and energy.
Bundle your compliance documentation with state-required field commissioning by a certified HERS rater from T24 Testing to receive additional discounts and ensure a seamless, streamlined process.
T24 Consulting and its sister company, T24 Testing, are owned and operated by certified California HERS Rater, Olaf Villadsen.
I founded T24 Consulting and Testing in 2024, but I have been doing mechanical and plumbing design, as well as Title 24 compliance, for clients in Santa Barbara County since I moved there in 2017. If your building was designed by Reese & Associates Architects, or if your mechanical system was installed by Anderson Systems between 2017 and 2024, there's a good chance I was involved.
My mission for T24 C&T is simple: I want to help build the housing that is so urgently needed in our state, and I want to make sure it’s done right. As a sole proprietor, I’m able to keep overhead to a minimum, and I’m committed to passing those savings on to my customers.
I handle equipment sizing, design, Title 24 compliance documents, and HERS testing—offering a complete, streamlined service.
I understand construction, constructability, and the cost implications of compliance forms and drawings, ensuring practical and efficient solutions.
I use specialized open-source compliance modeling software to reduce costs and provide more flexible compliance pathways.
I share all work products related to your project upon request, including CAD files and building energy models.
I offer remote inspection options for select HERS Rater tasks, saving time and hassle.
Q: How can you offer remote HERS testing?
A: Some HERS measures are simple inspections that can be conducted via video call, similar to a telehealth doctor appointment. Remote verification includes checking thermostat installation locations, witnessing refrigerant charge weigh-ins (performed by the contractor), and verifying the rated capacity and efficiency of installed equipment.
Q: Do you offer field HERS testing?
A: Yes, but only within Santa Barbara County. Some measures require specialized equipment and must be performed in person by a certified HERS rater. Visit our sister company, www.T24Test.ing, for more details.
Q: My Title 24 documents from another company were rejected by the building department. Can you help?
A: Maybe. It depends on the issue. Some cases require design changes, but in the past, I’ve successfully rerun calculations to prove compliance for projects that initially failed approval. It’s worth a shot.
Q: Why are your prices so low?
A: I have minimal overhead and a full-time job that covers my living expenses.
Q: How long will my compliance forms take to complete?
A: Turnaround time depends on project complexity. Simple projects typically take a day or two, while projects involving compliance, design, and drawings usually take about a week.
Q: What do you need to get started?
A: For the fastest service, please provide:
Floor plans and elevations
Project address
Owner contact information
Responsible designer contact information
Q: What if my proposed envelope design doesn’t comply?
A: I’ll analyze your building and suggest cost-effective measures to achieve compliance. You’ll receive a summary of changes along with the updated compliance documentation - at no additional cost.
Q: Do you charge for revisions if the project changes?
A: One round of minor revisions (for plan check comments or small project changes) is included free of charge. Additional revisions are billed at my standard hourly rate.
Q: Do you offer mechanical and plumbing engineering services?
A: No. To limit liability and minimize insurance costs, I only provide design assistance services. I sign compliance forms as the "document author" and offer schematic system designs and drawings, but all forms and drawings must ultimately be reviewed, signed, and/or stamped by another responsible party, such as an architect, licensed contractor, or owner-builder.
