NRG Solutions
NRG Solutions, founded by Micah Seierstad in 1999, provides California Title 24 energy reports and precision HVAC design using ACCA Manual J, S, D & T methodology. Based in Northern California with over 25 years of experience, Micah bridges the gap between energy code theory and real-world building performance — and teaches others to do the same as an instructor with Wollin Group.
About
Micah Seierstad founded NRG Solutions in 1999 with a straightforward mission: make sure buildings actually perform the way they're designed to. For over 25 years, he's been the person builders, architects, and contractors in Northern California call when they need Title 24 energy compliance done right — and when they need HVAC systems engineered by the book, not sized by guesswork.
In 2015, Micah expanded into full HVAC design using ACCA Manual J, S, D & T methodology, giving clients precision load calculations and duct design under one roof. He also teaches energy conservation and building science as an instructor with Wollin Group, Inc. — the kind of expertise that comes from doing the work, not just studying it.
Key Features
NRG Solutions combines deep Title 24 expertise with precision HVAC engineering — a dual capability that most firms don't offer under one roof. Micah's role as an industry instructor reflects the kind of mastery that comes from 25+ years of practice.

Why Choose Us
Most energy consultants do Title 24 reports. Most HVAC designers size equipment. Micah does both — and teaches the methodology to other professionals.
