Questions worth asking there

A claim at a show is a starting point. These questions help you test it.

  • Is the energy or carbon figure from post-occupancy measurement or from a design model?
  • Which certification or third-party review supports the performance claim, and at what stage?
  • Which completed building can be visited or documented to test this claim?
  • Which assumptions about occupancy and operations does the projected performance rely on?

Plan it

Guides for any show

First time at a major show

A show floor rewards a plan. Decide what you need to learn before you see the program, then let the program fill the plan.

Show planning checklist

The same checklist works for a payments summit, a marketing conference and a machine tool show.

Parking and getting there

Parking and transit change by event and by day. The venue and the transit agency are the sources to trust, close to the date.

Hotels and travel

Use the organizer's official housing page as your starting point. Third-party offers that use a show's name are not always connected to the organizer.

During the show

A claim on a show floor sounds as firm as a published figure. It usually is not. Keep the same few questions in your pocket, and class what you hear.

Meeting planner

A meeting earns its time when both sides know the question before they sit down.

After the show

The value of a show is decided in the two weeks afterward, when notes turn into decisions or get lost.
