AI summary The table presents data on the relationship between percent flow and percent full load power for different control methods, including inlet guide vanes, discharge dampers, and variable frequency drives (VFD). It shows how each method affects power consumption at varying flow percentages.
s shut off for 1,512 hours during the winter. Free cooling operation is a weather variable and will shut off the condensing unit when outside air temperatures drop below the temperature in the cooler. 5.0 On-Site Methodology The evaporator...
AI summary The document outlines the on-site methodology used to assess cooler systems in Truro and Dartmouth stores. It describes observations of equipment, data collection, and interviews with store managers regarding new installations and baseline operations. Managers reported no issues with the new equipment but had limited knowledge of baseline operations.
t but were not completely sure. They had no knowledge of baseline condensate heater operation. They have seen the outside air dampers open to provide free cooling but are not sure how often they work. 6.0 On-site Observations and Findings...
AI summary The on-site observations found that nameplate data matched tracking values for evaporator fans, condensing units, and door heaters. Cooler temperatures were satisfied during the visit, so outside air supply fans and compressors were not operating. Anti-condensate heaters were not on, and evaporator fans were off in most locations, with no indication of override or future shutdown issues.

AI summary The text presents a table summarizing verified and M&V fixture counts for various intersections, including details on traffic signals and pedestrian features. It provides quantitative data on the number of fixtures across different categories at each intersection.
In the M&V analysis, it was assumed that circular traffic signals were green for roughly 50% of the time in any direction and left turn arrows were green for 30% of the time. In order to illustrate why this is a problem, consider the persp...
AI summary The M&V analysis overestimated the time traffic signals were green and underestimated the time they were red at intersections with protected left turns. New operating fractions were devised to address these issues, distinguishing between protected and permissive intersections.
5% of the time; drivers traveling in the other two directions are moving the other 49.5% of the time. During the remaining 1% of a given cycle, all lights are red. Within the 49.5% of the time that drivers traveling in either direction A o...
AI summary The text discusses the distribution of traffic light cycles, with 50% of the time allocated to one direction of traffic, 49.5% to the opposite direction, and 1% where all lights are red. The lighting cycle is further divided into three combinations during the 49.5% period when traffic moves in directions A or B.

AI summary The text presents a table showing the distribution of business types across different years, with varying percentages and counts for each category. It includes data from 2008 to 2010, highlighting changes in the number of businesses in sectors such as service, retail, office, and manufacturing.
