To whom it may concern, March, 2008

Our company has been working with Mark Lantz in several of our rental buildings over the past year. He has helped us analyze each building for its energy inefficiencies and flaws and to identify effective and immediate solutions. We have been developing action plans to best prioritize the extensive amount of energy remediation work necessary throughout every building. Mark has provided substantial improvements

We have found Mark’s work to be very effective in reducing our energy use and understanding our buildings performance better. He has shown him self to be knowledgeable and effective as a certified Efficiency Vermont contractor. We plan to continue using his services for our entire inventory of rental buildings.

Please feel free to contact me if you have any further questions.
