"thank you Roy and Lawrence!"

I don't remember how I came across this company, but I am glad that I did. I moved into my condo about seven months ago, and I was curious about how energy efficient my place is. Thanks to Delta T Energy, I now know what to do in order to make the condo more energy-efficient; conserving energy and money, and making the home more comfortable. They performed an energy audit of my condo. They found many leaks in my place, using a blower-door test, and an infra-red camera for thermal imaging. Also, they tested my furnace ducts, and found that, although the ducts are tight, the furnace itself has a lot of leaks. Now, I know what I need to do to my place. I am very pleased with the energy audit of my place by Delta T Energy Consulting. Thank you Roy and Lawrence! I appreciate all of your advice. I will definitely call Delta T again. I recommend this company.

I have been working with Adrian the founder for a few years and now Roy and Whitney as well. The entire team is knowledge and a joy to work with. They are highly responsive and helpful with the latest code information, as well as product recommendations and they turn reports and documentation around very quickly. I highly recommend Delta T Energy as your one stop shop energy experts!

Builders' Studio

I have worked with Delta T for the past year completing a range of projects from remodels to new construction and have nothing but positive things to say. The team over at Delta lead by Adrian has provided great support and analysis to our clients. This has enabled our clients to meet requirements with options to exceed those requirements. I highly recommend Delta T to not only design professionals but to builders and home-owners as well.

"strong technical knowledge, sound advice and thoroughness"

I am extremely impressed with the strong technical knowledge, sound advice, and thoroughness of the consulting services at Delta T Energy Consulting. I am very pleased to be working with Delta T on my Sonoma Clean Power Advanced Energy Rebuild rebate project. My consultant, Roy, has been an excellent advisor – his command of energy principles, regulatory requirements, and product performance has been invaluable and his judgment on decision tradeoffs and incentive programs has been critical. I’ve appreciated the way Delta T can guide a project from planning, through Title 24, to testing, including CALGreen and HERS, through verification and submittal to TRC, or county permitting. On several occasions, Roy, has made extra efforts to work with other partners on my project to discuss methods or coordinate linkages. I highly recommend Delta T Energy Consulting.
