Yes, never before seen! These are the only existing records I have of the monumental task I was given when I worked for Yale University. Unfortunately they are just black and white screen shots that I printed out in our office. They are over 10 years old. I scanned them for the first time on 6/25/2016. I knew nothing about this proprietary graphics software, Yale’s computer network or even HVAC in general. I had no user’s manual and no one at the facility knew how to use this software. Somehow I figured out how to create these animated graphics, make them speak to Yale’s network in real-time and allow the user to make changes that were normally done through an archaic text based system that never even used.

1. Pretty hot that day!
All of these buttons were
clickable and often went to
other menus.
This building is more commonly referred to as OML.
This thermometer changed color
between red or blue depending
on the outside temperature. I
thought it was pretty neat when
I figured out how to do it. I
don't think many people noticed
until I pointed it out though.

2. If I could find any historical information on the building
being viewed I included it just for reference.

3. Location of Osborn Memorial Lab (OML).
Yale's President could live
in this house for free.
Building I worked in.
Kline Biology Tower (KBT).

4. All of this data was displayed in real-time.

5. Screens like this that had floor plans were
color coded depending on which Air Handling
Unit was controlling the room. It's not very
obvious because all these screenshots are in
black and white.
If any of these units had a
number in "alarm" status, the
box for it would blink red. I
also made a separate screen
(not shown) that displayed
any units in alarm.
Most of the buildings did not
have floor plans. OML was one
of the few buildings that did,
and for every floor.

9. These animated screens, which depict the air handling units,
look better in color. All the data boxes are updated in real-
time. Fans show to be spinning when they are on and idle
when off. Dampers show open or closed. The arrows move
and change color depending on the air direction. Hot or cold
water valves that are open will show red or blue dots to
indicate flow.
All these arrows move
depending on which fans
are on, dampers being
open or closed and etc.
These switches are functional. For example, this
switch selects which Supply Fan operates as the
lead. Supply Fan 1 has been selected. This can
be verified looking at this static picture. The
damper after Supply Fan 2 is closed and there
are no arrows which indicate air flow going to it.
If either Supply Fan was failing,
this box would be flashing red.

10. This particular unit is more straight forward than the one
on the previous page. It also does not have as many
pages of controls or independent data provided.
Note: This valve is partially
open. There are colored
dots to visually indicate
water flow.
Note: This valve is closed.
It has no colored dots to
indicate water flow.

13. This is just a quick overview screen of some of the more critical data that
was monitored for OML. Some of the features were adjustable (Any box
that has two buttons with arrows on them). Screens like this saved you
having to check on each unit individually.

14. This system didn't have a
lot going on when I took
this screen shot. Any pump
running would have a
section resembling a turbine
in the middle spinning.
Also, all the control valves
are shut.

15. This system shows Pump
One to be running.

16. This screen shows information about the send and return chilled water between OML and Sachem Street.

17. OML had many experimentation labs
where it was critical that the temperature
and humidity be within a certain range.
This is a quick overview screen showing
those values for each lab room. Any
value in alarm would flash red and
someone responsible for the experiment
in that lab was contacted. Generally,
things did not go over very well when that
happened.

18. Out of all the laboratories, I believe room 501 was considered to be the important and heavily monitored.
