November 19, 2020 - COVID update
For the foreseeable future, the College will only allow current PNCA staff, faculty and students into the buildings. Exceptions may be made for visitors who are performing essential work, such maintenance and repairs. The COVID-19 Task Force will reconsider this policy after Governor Brown lifts the "freeze” in Multnomah County. While we recognize this is difficult, we feel strongly that this is necessary to protect the PNCA community, as well as all of our families and households.
We plan for continuous facility access throughout the semester, with structured sign-ups to reduce the number of people in each space at any given time (while circumstances could change due to state law, this is the current intent). We’ll prioritize access for making, research, and all forms of creative practice, in individual and small-group settings.
Masks and Social Distancing
Masks are required in all shared spaces at PNCA. Physical distancing is required at all times.
One of the big changes at PNCA this fall is that attendance is not mandatory. We recognize that the outcomes of your education - the way you develop the skills necessary to graduate and succeed in your career - are the most important part.
We want to acknowledge that gatherings are a big part of the experience, so we do hope you’ll attend as many as possible, but we recognize that attendance is your choice - so attendance will not be required and calculated into the course grade.
If you can’t or don’t want to attend class in person, your instructors and advisor will work with you to find a suitable pathway forward.
511 Building HVAC and Water
- Fresh outside air is filtered into building through MERV-13 filters.
- MERV-13 filtration = 90% efficient in 1.0-3.0 micron range, less than 75% efficient in 0.3-1.0 micron range.
- Hospitals use MERV 13-16.
- Air is not cycled between spaces. Air moves from core and out through windows.
- Building maintains positive pressure. Exhausting air to the outside.
- Exceeds ANSI recommended ratings (ASHRAE Standard 62.1) by 44% at full occupancy, significantly higher for lower numbers of people in the building.
- Currently no way to measure airflow on a per-room basis.
- Taken steps to ventilate stairwells.
- Stairwells now ventilate at approx. 3 ACH (air changes per hour).
- Leave stairwell restroom doors open every other floor to draw stairwell air into restroom HVAC.
- Elevators ventilate naturally via the piston action of the car within the hoist way.
- Increased water pressure building-wide by 30% for more effective hand washing and flushing.
- Currently flushing every device in the building 1x per week.
- Added hand-wash stations at utility sinks on floors 3-6.
511 Building Sanitization Plan
- Hand sanitizer stations present at every elevator stop, as well as added to classrooms.
- Classrooms supplied with cleaning caddy/kits comprised of the following:
- Paper towels.
- Surface sanitizer containing n-Alkyl dimethyl benzyl ammonium chlorides & n-Alkyl dimethyl ethyl benzyl ammonium chlorides.
- 70% isopropyl alcohol wipes for computer equipment.
- Cleaning caddy/kits for common use in the Atrium.
- Scheduled daily cleanings by janitorial staff.
511 Building Traffic Flow Plan
- Designed as guidelines for class changeover periods.
- Not designed to be enforced 24/7.
- ADA requirements supersede other concerns, driving plan layout.
- ADA also overrides other elevator use. (2 occupants per elevator)
- Staggered class scheduling will improve flow.
- Floor striping at areas prone to crowding.
- Service offices will be left to devise their own plans.
511 Building Classroom Use and Occupancy
- Recommend minimizing occupancy use concentration by implementing low occupancy per classroom, allowing classroom to “rest” in between uses, and minimize/eliminate assigning adjacent classrooms during same time slot if possible.
- Signage (yellow COVID) - Post maximum COVID occupancy rating, and do not rearrange furniture, on door and inside classroom
Glass Building HVAC and Water
- The Glass Building is a unique case in terms of airflow and ventilation. Having an approximate R value of <1 and being of mostly original construction nearly 100 years old, its envelope in terms of air retention is tremendously porous.
- While we do not actively supply outside air into the space, nor actively exhaust in any meaningful way, the building 'breathes' via the stack effect quite well.
- Being essentially a greenhouse, the interior of the space is heated via natural light infrared energy, and the air within it rises, escaping through all the gaps and voids in the envelope, while cooler air is drawn in from near ground-level.
- Air is circulated through the space by two 20' fans which run continuously during warmer months at ~30% speed (pleasant maximum speed is ~50%), and in reverse at ~15% speed during colder months.
- The Gallery/Sewing Classroom, Mezzanine Office, and Second Floor Offices are heated and cooled via a ducted heat pump. The Gallery air is directly conditioned within the room, while the Mezzanine and Second Floor Offices use recirculated air with hospital grade MERV 13 filters.
- The Break Room is heated with in-wall heaters and a window-type air conditioner.
- The Glaze Room is heated by a gas forced air heater and cooled by a window-type air conditioner.
- Water pressure is estimated to be approximately 65PSI, though no gauge is present. Supply is regulated and may possibly be increased for greater water flow.
- Toilets/urinals are all high flow type and remove waste effectively.
Glass Building Sanitization Plan
- Cleaning caddie/kits for common use have been placed in all shop and classroom spaces, and hand sanitizer dispensers installed in all entryways and corridors.
- Janitorial is scheduled for restrooms, kitchenette, and common area.
Glass Building Traffic Flow Plan
- Floors marked off for physical distancing with painted lines in Woodshop, Metal shop, and Ceramics rooms. Floor spacing markings at the entrance. Directional floor arrows in the MFA studio space.
Glass Building Classroom and shop use occupancy
- Signage (yellow COVID) – Post maximum COVID occupancy rating, and do not rearrange furniture signs on doors and inside rooms.
