About the previous site at this address

If you followed an old link here looking for commentary on climate, energy and the environment, this page explains what happened.

The previous site has been replaced

This domain previously carried a newsletter. Its author owns this domain and has chosen to replace the site. Every old address now returns a "gone" response.

Nothing from the newsletter is reproduced here, and this site does not continue it in any way.

What this site is now

A collection of notes on occupancy analytics: measuring how building space is actually used, which methods work, and where measuring space turns into monitoring people.
