for GAStech employees?
Limit your response to no more than 6 images and 500 words.
Most employees come in, go to their office and stay there
except for meetings, lunch and occasional restroom stop:
Security
Floor one security: 8a-5p, staggered lunch out
(12-1 and 1-2). Both visit the deli in morning and at 3:00. After 3:00 convene
in 1010
Floor two security: 8a-5p, lunch out 12-1. Spend
most of their days in 2170.
Floor three security: 8a-5:30, lunch out
12:30-1:30.
Security has meetings on Tuesdays and Thursdays
8:10a-8:54a. First floor security alternate who comes up for the meeting. Mihalis Vollan takes an early
lunch and covers 1010 while Stenig Fusil is at lunch.
IT
First shift:
8:00-5:00, lunch 12:00-1:15 in the deli, two meetings a day with engineering in
2700, 10:30a-11:30a and 2:00p-3:00p
Second
shift: 4:00p-12:00a, meal 8:15-8:45 in the deli, two meetings a night with
engineering in 2700, 6:30a-7:30a and 10:00p-11:00p
Engineering
First
shift: 7:30a-5:00p, lunch 12-1 in the deli, two meetings a day with engineering.
Second
shift: 4:00p-12:00a, meal 8:00-9:00 in the deli, two meetings a night with
engineering
Facilities
First
shift: 12:00a-7:00a, mostly stay in office, going to 1030 for 2:30-3:30 and
6:00-7:00 every morning
Second
shift: 7:30a-5:00p, lunch 12-1 in the deli, breaks at 10:30 and 2:30 (they go
to the prox zone with the break room)
Third
shift: 4:00p-12:00a, meal 8:00p-9:00p, breaks at 6:30p and 10:00p
Administrators
8:00a-5:00p,
varies when they take lunch, but it is typically an hour and usually at the
deli.
HR
8:00a –
between 4:30p and 5:30p, irregular meals, possibly eating in offices, meetings on
Wednesdays 2:30-4:15
Executives
7:30a/8:00a
– 5:00/6:00, irregular lunches, less constancy in schedules
MC2.2 – Describe up to ten of the most interesting
patterns you observe in the building data. Describe what is notable about the
pattern and explain what you can about the significance of the pattern.
The temperature and REHEAT Coil power are placed into a wild oscilations in room 3000 shortly before the first major hazium spike. This is notable because the swings are large
(32 is quite hot and 8 is quite cold), and it is left uncorrected for the
remainder of the period. The fact that this occurs in room 3000 where we have
our first major spike in hazium readings cannot be
ignored either.
Most of the HVAC systems display very regular daily patterns.
This is key, because when they are disrupted around the spikes in hazium, the changes stand out and are observable.
MC2.3 – Describe
up to ten notable anomalies or unusual events you see in the data. Describe
when and where the event or anomaly occurs and describe why it is notable. If
you have more than ten anomalies to report, prioritize those anomalies that are
most likely to represent a danger or serious issue for building operation.

Patrick Young's prox
card is stolen
- After getting second prox
card his first card is only used to enter server room 3440 from the second
floor
- the prox card registers in the server room at 10:20 on the 2nd,
3rd, 8th, and 10th while
the
second prox card shows Young in his office
- The mobile prox
registers the missing card with lbennet while the
static system shows it elsewhere
- This
suggests that Young's prox card was stolen in order
to conduct suspicious business in the server room
HVAC abnormalities during hazium
spikes on June 7th and 8th
- During
the hazium spikes on floors 2 and 3 (June 7th/8th),
the following HVAC sensors exhibit unusual behavior:
- The
temperature swings in F2Z2 and F2Z4
- The
VAV Damper Position in the server room oscillates
-
Spike in HVAC Electric Demand Power
- SYS
Supply Fan: Fan Power (Floor 3) becomes lower than usual and oscillates
- SYS
Supply Fan Outlet Temp on Floor 3 spikes, on Floor 2 drops
-
Outdoor airflow fraction spikes and oscillates on Floor 3 and spikes on Floor 2
-
Cooling Coil Power on Floor 3 drops
- Airloop Inlet Temp on Floor 3 spikes and oscillates, on
Floor 2 drops
-Reheat Coil Power spikes
- This
demonstrates a clear HVAC relationship with rising hazium
levels
HVAC abnormalities during Hazium
spike on June 11th/12th. While these also seem to accompany the rise
in hazium levels, the effects are different.
- Hazium levels begin to rise June 11th at 12pm, peaking at
6pm, and falling back to minimal levels by June 12th at 6pm
- Floor
1 and 2 supply Fan power is high until peak and then begins to oscillate, while
Floor 3 remains high the whole time
-
Supply Fan Mass Flow Rate is higher than normal on all floors
- Floor
1 and 2 Outdoor airflow drops
- Floor
1 and 2 Cooling Coil Power spikes
- Floor
1 and 2 Air Loop Inlet Mass Flow Rate oscillates
- Floor
1 and 2 Reheat Damper Position oscillates
- Floor
1 Mechanical Ventilation Mass floor Rate is high
-There
is abnormal fluctuation in Total Power levels
-
Reheat Coil Power oscillates
- The
breaking of normal HVAC patterns demonstrates a connection between building
atmosphere and Hazium levels
Four facilities employees leave their prox cards behind when they leave for the night
- Dante Coginian leaves his prox card in
F2Z1 (potentially in break room) on Tuesday nights (May 31st, June 7th)
- Effie
Davies also leave her prox card in F2Z1 on Tuesday
night, May 31st
- Valeria
Morlun leaves her prox card
in F2Z1 on Tuesday night, June 7th, while Adan Molrun
leaves his in the elevator/stairs (F2Z4) on the same night
Lost Prox Cards
- those
who have lost their prox card receive additional prox card IDs that are registered in the building
- most
employees lose their prox cards in the lobby or in
their office
- Jae
Unger loses his prox card on June 9th
- Lucas Alcazar loses his prox
card on June 6th
- Valeria
Molrun loses her prox card
on June 3rd
- Patrick
Young (who has one of his prox cards stolen) receives
a new prox card on June 2nd
- Geneviere Florez loses one prox card on the 1st, another on the 2nd, and a final on
the 3rd
- Twana Quirox loses her prox card on the 7th
(
Half of the security employees never show up in
the data
-
Dorothea Bartley, Mi Canada, Summer Holiday, Paulita Kemp, Mathias Notaro, Alcide Pherigo, Dong Rhoads,
Selma Salvay, Xiomara Sowell, Edvard
Vann
Coming in
on the weekend
- both Orhan Strum and Mat Bramar come
in on Saturday, June 11th (the day of a major hazium
spike)
- Interesting
because this is unusual and marks the beginning of a large spike in hazium levels.
MC2.4 –– 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.

When meetings occur, we can
detect them through upswings in CO2 levels and temperature. The most obvious
instance of this occurs in the daily meetings at 10:30a
and 2:00p of the joint Engineering and IT departments. We are very confident of
this as we can see when the departments go to prox
zone F2Z6 and we can see clear bumps in the HVAC levels of 2700 at these
points.
Light power and equipment
power show when employees arrive and leave. This is most obvious in single room
HVAC zones such as the conference rooms and the corner offices. We are highly
confident of this.
We speculate that increased
levels of hazium or related effects to the HVAC
system are causing discomfort. Several employees break their patterns around
the time of spikes in hazium activity. Rachel
Pantanal, who has an office on the third floor, goes home
early during the first major spike in hazium levels. Ruschella Haber and Linda Lagos change their lunch habits, leaving the
building for lunch on the day of the first spike (and Linda also leaves the day
of the second one). The connection here is weak, but merits further
investigation.
