Small sensors collect light, activity data for energy project

When are lights on in rooms throughout Belknap Campus? When do people use each room?

Small sensors collect light, activity data for energy project

Contractors working on the Belknap Campus energy audit and savings performance project need to know the answers, but rather than conduct a tedious online or e-mail survey of all units, they are relying on a small, plastic data collector to provide the information they need.

At the end of January, Eco Engineering started installation of lighting system data-gathering devices, like the one pictured in the Schneider Hall art galleries. The company also will install them in other Belknap Campus buildings.

About the size of a deck of playing cards, the sensors record only lighting levels, time of day and movement in the area. They do not record images or voices, said David Logsdon, a technical specialist in the Office of the Vice President for Business Affairs.

Faculty, staff and students should maintain normal behavior patterns and schedules so the data is as useful as possible, he said.

The devices are not permanent and will be removed.
