Questions

As an expert in visual analytics, you have been hired to help GAStech understand its operations data. In this assignment, you are given two weeks of building and prox sensor data. Can you use visual analytics to identify typical patterns of and issues of concern?

You will be asked to answer the following types of questions:

1. What are the typical patterns in the prox card data? What does a typical day look like for GAStech employees?
2. Describe up to ten of the most interesting patterns that appear in the building data. Describe what is notable about the pattern and explain its possible significance.
3. Describe up to ten notable anomalies or unusual events you see in the data. Prioritize those issues that are most likely to represent a danger or a serious issue for building operations.
4. Describe up to five observed relationships between the proximity card data and building data elements. If you find a causal relationship (for example, a building event or condition leading to personnel behavior changes or personnel activity leading to building operations changes), describe your discovered cause and effect, the evidence you found to support it, and your level of confidence in your assessment of the relationship.

HVAC Information and its Significance

Field	Units	Description
F_#_BATH_EXHAUST:Fan Power	[W]	Power used by the bathroom exhaust fan
F_#_VAV_SYS AIR LOOP INLET Mass Flow Rate	[kg/s]	Total flow rate of air returning to the HVAC system from all zones it serves
F_#_VAV_SYS AIR LOOP INLET Temperature	[C]	Mixed temperature of air returning to the HVAC system from all zones it serves
F_# VAV Availability Manager Night Cycle Control Status		On/off status of the HVAC system during periods when the system is normally scheduled off. The night cycle manager cycles the HVAC system to maintain night and weekend set point temperatures.
F_#_VAV_SYS COOLING COIL Power	[W]	Power used by the HVAC system cooling coil
F_#_VAV_SYS HEATING COIL Power	[W]	Power used by the HVAC system heating coil
F_#_VAV_SYS SUPPLY FAN OUTLET Mass Flow Rate	[kg/s]	Total flow rate of air delivered by the HVAC system fan to the zones it serves
F_#_VAV_SYS SUPPLY FAN OUTLET Temperature	[C]	Temperature of the air exiting the HVAC system fan
F_#_VAV_SYS SUPPLY FAN:Fan Power	[W]	Power used by the HVAC system fan
F_#_VAV_SYS Outdoor Air Flow Fraction		Percentage of total air delivered by the HVAC system that is from the outside

COOL Schedule Value	Example	The supply air temperature set point. Air exiting the HVAC system fan is maintained at this temperature during cooling operation
DELI-FAN Power	[W]	Power used by the deli exhaust fan
Drybulb Temperature	[C]	Drybulb temperature of the outside air
Wind Direction	[deg]	Direction of wind outside of the building
Wind Speed	[m/s]	Speed of wind outside of the building
HEAT Schedule Value		The supply air temperature set point. Air exiting the HVAC system fan is maintained at this temperature during heating operation
Pump Power	[W]	Power used by the hot water system pump
