Advanced Building Analysis, LLC

After 18 years of HERS Rating and supporting Phius Verification in Massachusetts, Advanced Building Analysis, LLC has exciting news to share and much thanks to give to all of our clients and our ABA team and everyone who has supported us over the years.

ABA has assigned all of its multi-family Phius Verification work to RDH Building Science (Building Enclosure, Engineering & Consulting Services – RDH | Making Buildings Better™,) and assigned all of our other HERS Rating work to the most capable care of Home Energy Raters (HERS Ratings | Building Performance Testing | Home Energy Raters.)

This was not a decision made lightly. Gail and I felt we needed to do this to best support ABA's growing client base. We came to this decision only after considering many different options to best support overall growth in HERS Ratings plus particularly fast growth anticipated in Phius Passive Building Verification and large building air leakage testing.

Half of our team has joined Home Energy Raters where Gail is currently deeply involved in this transition. Home Energy Raters is the largest HERS Rating Company in Massachusetts and is most able to absorb our HERS Rating clients and continue to help them achieve their HERS Rating performance goals.

Meanwhile, I am excited to join RDH to lead a team whose primary job will be Phius Passive Building Verification. Matt Nardone from ABA has also joined RDH to continue serving our Phius Verification clients.

At RDH, we will happily continue to support all of the Phius Verification projects that have been transferred from ABA, as we continue to expand and support Phius Verification and large building air tightness testing in Massachusetts and beyond.

For Gail and I, ABA was a deep commitment and a very important part of our lives. We greatly appreciate everyone who was involved with ABA over the years.
We wish you all a meaningful and fulfilling 2026!

We are thrilled to help our clients pursue "energy positive" building performance - meaning their buildings produce more energy than they consume on an annual basis. This can be cost-effective when this is a central part of the design criteria, and it can be done even with large multi-family projects in urban areas. The DOE Zero Energy Ready Home program is a great basis for achieving this.
