Get StartedT24 Consulting and its sister company, T24 Testing, are owned and operated by certified California ECC Rater, Olaf Villadsen.
The mission is simple: help build the housing that is so urgently needed in California, and ensure it's done right. As a sole proprietorship, overhead is kept to a minimum, with those savings passed directly to clients.
Complete streamlined service handling equipment sizing, design, Title 24 compliance documents, and ECC testing
Deep understanding of construction, constructability, and cost implications ensuring practical and efficient solutions
Specialized open-source compliance modeling software to reduce costs and provide more flexible compliance pathways
All work products shared with upon request, including CAD files and building energy models
Remote inspection options for select ECC Rater tasks, saving you time, money, and hassle
Expert knowledge of the microclimates found in Santa Barbara County, and years of experience leveraging that for more sustainable and comfortable systems
Provided mechanical and plumbing system sizing and full "existing + addition" Title 24 energy simulation to prove compliance using existing 2x4 framing, saving the homeowner significant cost and preserving the full useful square footage of the limited space available.
Provided design assistance and "performance approach" modeling to prove compliance for mixed-use commercial building utilizing several innovative approaches to reduce energy consumption, including passive night cooling, on-demand water heating, heat pumps, and engineered metal-foam sandwich panels to achieve a low carbon footprint while meeting the client's tight budget constraints.
Provided mechanical and plumbing system sizing and energy modeling for new high-efficiency all-electric standalone ADU utilizing high-performance envelope assemblies, PV, ERV, and heat pumps for water heating and space conditioning to achieve very high energy efficiency exceeding code requirements by over 50% without increasing costs over a typical design that would have required costly electrical and natural gas service upgrades.
Performed multi-dimensional finite element calculation for custom roof and wall assemblies that had accidentally been installed with only 1/10th of the originally prescribed thermal break insulation. The project had been abandoned by the original energy consultant who was unable to analyze the building in its as-built condition due to the assemblies not being available in their simplistic compliance software. T24 Consulting proved compliance, saving the general contractor tens of thousands in rework, and allowing the client to receive building department approval in time for their required opening date.
"I use T24 Consulting for all of my projects. Not only do they provide fast service and reasonable prices, they also manage to stay on top of the latest technology and ever-changing Title 24 rules. Their documentation is the most detailed and accurate I have seen, passing scrutiny by even the most rigorous plan checkers without corrections!"
"T24 Consulting helped size and select a high-efficiency mini-split air conditioning system for our ADU project, and when we decided to modify the building design they adjusted their calculations and provided the revised compliance forms free of charge.
We couldn't be happier with the service we received."
Bundle compliance documentation with state-required field commissioning by a certified ECC rater from T24 Testing to receive additional discounts and ensure a seamless, streamlined process.
Using the latest open-source software, T24 Consulting quickly and accurately models, analyzes, and documents building performance. Services include energy modeling, compliance documentation, equipment sizing, ventilation system design, and ECC testing coordination.
