Green Armor is a building energy compliance and decarbonization consultancy. We turn utility data and field evidence into defensible, financially quantified recommendations, grounded in metered data, not desk estimates.

The difference
Metered data and field evidence.
Not desk estimates.

Most consultants pull a benchmarking export, run a spreadsheet, and hand over a number. We trace the number back to the equipment that produced it. Every figure in a Green Armor deliverable is defensible to an owner's engineer, and that method is identical in Los Angeles and Austin as it is in Manhattan.

  • Portable method, parameters as jurisdictions. The engineering doesn't change city to city, only the caps, deadlines, and penalty math do. One consultant for a portfolio anywhere in the country.
  • Compliance is the entry point, not the product. Owners come in needing a filing. They leave understanding what their building is doing, what it will cost, and what to fix first.
  • Cut where the rules are hardest. Our home market is NYC, the most demanding building-energy framework in the country. That depth travels to every market we serve.

What we do

Three ways we show up for owners.

From the first filing to a full decarbonization plan, a single team that can read the meter and the mechanical room.

$3M+

We found $3 million hiding in one
Fifth Avenue hotel's mechanical room.

Steam consumption up 80% and electricity up 66% year over year, with no obvious cause. We traced it, quantified it, and modeled the fix, $3M+ in cumulative savings and avoided penalties through 2034.

The jump traced to a simultaneous heating-and-cooling fault: a steam-to-hot-water heat exchanger running straight through the summer while electric chillers fought it. We confirmed it with segregated house-steam meters, infrared readings, and four years of verified metered data, then modeled the full remediation.
