Residential and Commercial Energy Code Compliance


As Title 24 experts, we specialize in recommending efficient building design features that comply with California's Building Energy Code.  Our experience with the code lets us guide you through Title 24 energy requirements. Abbay Technical Services will inform and advise throughout the project.


With California having ambitious sustainability goals, the building energy code plays a key role in the permitting process. Our goal is to allow flexible building design while maintaining comfortability and efficiency. We help navigate California's Energy Code for you.


Abbay Technical Services keeps communication clear when it comes to the modeling process. We understand the building process can be expensive. We collaborate with designers, engineers, homeowners, and contractors, to find the best options for short and long term savings.


Established in 1985 by William N. Abbay, Abbay Technical Services was founded with the objective of offering California Title 24 energy calculations and consulting services. In 1990, Anne M. McQueeney joined the team and apprenticed under Bill for 11 years until she acquired the business in 2001. Over the years, Anne conducted numerous energy calculations for residential and commercial buildings across all 16 climate zones in California. After a successful career, Anne has retired, passing the reins to her son, Anthony K. McQueeney, who now leads the office.


Since 2020, Anthony has been immersed in the intricacies of the Energy Code and has earned the certification of a Certified Energy Analyst through the California Association of Building Energy Consultants. Abbay Technical Services will continue its commitment to providing accurate and invaluable T24 Services throughout the state of California.


At Abbay Technical Services, our primary focus is finding the most cost-effective approach to building design while adhering to California's energy code. We take our time to discuss options with our clients to guarantee accurate and efficient reports. We collaborate closely with architects, builders, contractors, developers, engineers, and homeowners, ensuring the necessary documentation is prepared for permit submittal. Effective communication plays a crucial role in the compliance process, and we make certain that all involved parties are well-informed throughout the duration of the project. We pride ourselves on having a customer service quality that goes unmatched.
