In class today I will discuss the WWW-based Building Occupant Survey developed by our own Center for the Built Environment (CBE). These links lead you to results from two previous surveys of Wurster Hall occupants.

Using historical trend data from the Broadwind system, I was able to get some higher resolution data for the operation of the Wurster fans. The table below represents the opperation on a Weekday (Thursday 3 December) and a weekend (Saturday 5 December).
This post describes the technique to get historical data out of the Broadwind Building Management system. This historic data can be used to generate plots like the one below, that supported my analysis of the December 7 curtailment. Read on for step-by-step instructions.

Objective According to the October 2008 Wurster Hall occupant survey, 33% of occupants with a workspace in one of the design studios in the North wing of the building1 are often cold during cool weather. The objective of this study is to determine the cause of thermal discomfort in Wurster Hall’s 9th floor studio space [...]
During the first curtailment week, Mark and Jeff deployed CO2 monitors in four Wurster Hall locations: the Architecture Office (232), the 9th floor studio (900), the auditorium (112), and the 9th floor seminar (tube) room (901). Each of the CO2 monitors was sending readings to a HoboVolt programmed to record data at 10-minute intervals. Each [...]
After the class’ discussion about using a bag of known volume to characterize ventilation rates, Jeff developed a prototype that seemed to work quite well. I became curious about whether this method had been tried before. I started making inquiries and was quickly directed to Darry Dickeroff, a Principal Research Associate, at Lawrence Berkeley National [...]
We will be observing the number of occupancy and percentage of lighting…
