The bill arrives and nobody can say which nights ran it up.
CrossVenue reads the building controls, the meters and the event calendar as one picture. Out comes a short list of decisions for today. Each one shows its arithmetic.
Before the doors open
It runs on the building's operations machine and reads systems you already have.
Building management data, the meters, and what is booked.
It writes no setpoint and overrides no schedule. Nothing is actuated.
A gap in the meter data lowers the confidence, and the missing hour is never interpolated away.
The building ran all day for an event that used two floors.
Ventilation and conditioning run to a schedule that was set when the building opened and has not been looked at since. The calendar knows the event was in one hall. The controls do not.
The bill arrives thirty days later as one number, and by then nobody can say which nights were the expensive ones or why.
It compares the air being moved with the crowd that is in the building. Air moved for an empty hall becomes a line on tonight's list.
A short list, with the arithmetic under each one.

It puts the calendar next to the meter.
The controls, the meters and the bookings, for the same hours.
Where the building is running for space nobody has booked, or running short for space that is.
Every recommendation carries the calculation behind it, so somebody can argue with it.
A gap in the meter data means no forecast.
A missing hour stays missing. It lowers the confidence and gets named, because a forecast built over a hole is how you lose an argument with finance.
- 1Find the meter that keeps dropping out
The report names it. One flaky meter is usually behind most of the gaps, and fixing it lifts the confidence across every recommendation.
- 2Then get the calendar in properly
Half the value is knowing what was booked. A calendar that is right two days ahead is worth more here than one that is right in hindsight.
- 3Then argue with the arithmetic
Every number shows its working, so somebody who knows the building can point at the assumption that is wrong.
Does it control the building?
Does it control the building?
No. It reads and it recommends. A person makes every change.
What systems does it need?
Building management data, metering, and the booking calendar. Where one of the three is missing it says which, and what that costs the answer.
Is this an energy management system?
No. An energy management system tells you what happened. This turns what is happening into the two or three calls somebody has to make before tonight.
Where does the arithmetic come from?
It is shown on every recommendation, with the assumptions named. If an assumption is wrong for your building, you can see that it is wrong.
See it work
Four in the afternoon, and there is a full house tonight.
A real run: eleven calls, seventeen things broken, a number in dollars, and a search across thirty recorded nights. The building here is a ballpark, because that is the venue the engine ships a sample for. It is a real one and its name is withheld, so the physics are somebody’s and the identity is nobody’s.
Start here. You will take a decision, open the arithmetic under it, read what is broken, look at the money, and see what the search refused to recommend. It takes about a minute.
Eleven answers, and a count of how much it is allowed to claim.
It ends on the feeds because that is where every figure above it comes from. Nine sources, none of them connected in this sample, and the product says so on the screen, not in a footnote.
Sample data, from a real venue whose name is withheld. Every figure is the engine’s own output.
When the question is the network under the building
CrossVenue runs one site at a time. Whether the network under that building is right is a question for CrossConnect.
CrossVenue next to the other sevenCrossVenue hands you tonight's decisions, with the arithmetic under each, which is where CrossConnect picks up: “Is it right, and what breaks if it fails?”
Bring one event and one utility bill.
Bring one event from the calendar and the utility bill for that month. In thirty minutes we show you how CrossVenue lines the two up, and where each number comes from.
