Eco Friendly Buildings


Founded in 2017, the mission of Delta T Energy is to help homeowners, architects and contractors achieve their green energy design goals. 

OUR MISSION   is to help people implement green design practices in residential and commercial building space. We will ensure our customers are informed regarding the benefits of integrated green building design. We will construct comfortable modern homes and commercial spaces in a way that is minimally invasive to the earth all while keeping the expenses to a minimum. It is our hope that through these practices we can help create buildings which work symbiotically with both our surroundings and budgetary goals.  

IN THE FUTURE   Delta T Energy will branch off into a sustainability driven developement firm where we will create passive/carbon neutral homes using recycled and natural materials. Additionally, we are in the process of researching and designing a solar powered aquaponics system for low input food cultivation. This system can be integrated into custom homes for fresh, low cost food and vegetables. We hope that in the future we will be fortunate enough to design and build Zero Net Energy green communities where neighbors can live together on shared-space properties in a supportive, conscientious, and environmentally friendly way. 

Brick Wall Building

     After graduating from Sonoma State I immediately took a position at the green building consulting firm at which I had interned during school.  Luckily they were the best of the best in the industry.  Throughout my first year at that company I studied like crazy and earned my California CEA license, HERS rater license, ACCA J, D, & S license, and CALGreen special inspector license.  The experience that I gained from my time at the green building firm was invaluable and led me to eventually starting my own firm.  I like to stay busy looking to broaden my horizons and gain knowledge. For that reason I'm currently continuing my education through BPI certifications and mechanical design courses.


We understand that navigating building codes can be difficult. Our clients find peace of mind knowing that our energy consulting team is here to guide the way. We use the newest integrative technologies to assist in commercial and residential designs, making them both green and affordable.
