How This Works
The Right Information, at the Right Moment

Every property decision has an MEP dimension — energy cost, system age, compliance exposure, carbon trajectory. These tools give you a clear starting position before you engage a design team.

01
Screen

Run any tool with the information you already have. Building type, age, floor area — that's usually enough to get a clear starting position.

02
Understand

Get a clear output with flags, benchmarks, and context. Every result tells you what it means, what it costs, and what it can't tell you.

03
Decide

Use the screening to shape your next conversation — whether that's with a vendor, a design team, or us. You set the pace.
