also it's unfortunately pretty loud, and while it was probably doing a lot of
airflow, the noise was a bit too much for it to be useful. Maybe we can find a
different kind of fan and place it on the roof nearby and duct it to the
skylight, so that it doesn't put its weight there.

All, I wanted to update re sudo’s DIY roof ventilation
exhaust fan. After
consulting with an electrician, I think this needs to come down, at least
during the rainy season. Reasons are:
- Fan power connections are not exterior rated and fairly exposed to the
- Fan chassis is mounted within a portion of skylight glazing. Fan
vibration may weaken window sealant leading to roof leaks.
- Fan extension cord has broken sheathing, exposing wires
- Extension cord left dangling down into sudo is Sudo’s most visible fire
In light of the above, unless there is any objection, power has been
disconnected from this exhaust unit, and the hanging extension cord will
also soon be removed.
In lieu, we will design a more code-conforming solution to address
ventilation needs in Sudo, which I recognize it needs. I welcome all input.

Per prior discussion, electrical maintenance will be conducted to increase
the number of available receptacles in the southeast portion of sudo room,
near sudo's fridge & stairs down to basement, in order to remove
life-safety hazards presented by excessive extension cords / power strips
in this location under/adjacent to an unrated mezzanine etc. This work is
now planned for *Monday 10/18 in the AM.*
This work will likely require temporarily de-powering one or more circuits
to Sudo Room presently feeding receptacles in this particular area and
along portions of the south wall.
Please ensure all steps are taken to save work and safely depower
equipment in this area prior to this work, *or provide me with
instruction to safely do these things*, *including the sudo mesh cage.
This work may impact internet access within the building while work is
being undertaken.* The maintenance window is not planned to last longer
than a single day.
'Small' one-off jobs like this can be difficult to affordably schedule
well in advance, as they are typically subject to electricians' squeezing
in the work around bigger jobs they have elsewhere. Therefore, in most
cases we are unlikely to get more than ~2 days advance notice as in this
Separately, on Sunday 10/17, an electrical assessment will be undertaken
to see how providing more compliant power to the ad-hoc / DIY exhaust fan
on sudo's roof (south roof area of back room) could be accomplished.
Providing more permanent electrical power to this fan will not necessarily
be undertaken sunday, but it is possible. Assessing / addressing the roof
fan issue should not directly impact power to sudo or ccl on Sunday, but if
and when this becomes required, I will notice sudo and ccl.
Thanks to everyone for bearing with these ongoing life-safety improvements
to the building and please hit me up with any questions or concerns.
