I have used the professional services of Beth Smithwick and CompuCalc for over 12 years and have always been impressed by her Business Orientated approach. Her service has always been prompt and accurate as the State Energy Calculation requirements are constantly changing. I know that she will keep me in the loop as a Residential Designer and I am confident that I will always be aware of any changes or upgrades required by the State Energy Commision.

As an owner builder, I used Beth (CompuCalc) to provide the Title 24 requirement for a garage conversion project I am working on. I found Beth to be knowledgeable, professional, timely and very pleasant to deal with. I am a very analytical person, retired after 35 years of supply chain management experience with Hewlett-Packard, and had many questions about my project. Beth went well beyond my expectations in providing quality answers. I high recommend CompuCalc for your Title 24 needs.

I have used Compucalc for several years on many of my small residential projects. They have always provided quick turn around of the required calculations at competitive pricing. Beth is responsive, current on the latest regulations, and offers great input. She has also helped to keep me informed about the changes affecting my projects every time the Energy Efficiency Standards have been updated.

Beth Smithwick has provided energy conservation design consultation and documentation for my projects for many years. I have found her to be most personable, responsive, timely and thorough with her professional services. She has beneficial recommendations for economic ways to save energy in construction methods and equipment selection. And her energy documentation has always received approval with the first submittal to building departments. I have appreciated and enjoyed working with Beth, and highly recommend using her company CompuCalc for building energy documentation.
