One advantage of conducting after-hours building walk-throughs to collect data on office equipment power status is that more buildings can be surveyed with a given amount of time and money. On the other hand, the data collected represents a snapshot in time, and does not capture variations in user behavior over time, which would require automated long-term time series metering of equipment power state and power levels. This is our most robust sample of buildings to date for collecting data on the after hours power status of office equipment. It includes data on 1,683 computers (including desktops,.
