Mt. Angel Abbey

• Abbey founded in 1882 by Swiss Benedictine monks.
• In 1887 the monks established the Mt. Angel
  college High school.
• In 1889 under direction of the Archbishop of
  Oregon City, seminary was established.

The Library

• Designed by modernist Finish architect Alvar
  Aalto ( Famous for designing M.I.T. Baker House
  residence hall)
• Completed in 1970
• 44,000 sq ft., three-story
• Over 5000 Rare book collection and antiquities

5
The Issue

• Under built HVAC system
• Over 40-years old system. Almost end of its life
  cycle.

During the original mechanical design work for
this project, consideration was given to minimum
provisions for future air-conditioning (i.e.
cooling) -OKelly and Schoenlank

The Issue

• Occupant discomfort in Carrels, Auditorium,
  and Catalog room.

7
The Solution

• Evaluate and model an efficient HVAC system.
• Select a monitoring system for a vault that has
  temperature/humidity sensitive materials.
• Estimate a payback period for the new system.

PDS

• Primary requirements
• Thermal comfort for occupants defined by ASHRAE
  Standard 55-2004(General occupancy standard)
• Ventilation and Indoor Air Quality defined by
  ASHRAE Standard 62.1-2004(General occupancy
  standard)
• ASHRAE requirements for preservation of public
  collections.(Library specific standard)

9
PDS

• Secondary requirements
• Low lifecycle cost
• Low Energy cost
• The system needs to generate less than 40
  decibels of background noise
• Design Constraints
• No changes to the interior or exterior design
• Minimal changes to ducting system

Major Risks

• Failure to control temperature and humidity in
  vault and otherrare book rooms
• Reduction
• Collect data about current environment
• Research ideal conditions for books and
  antiquities
• Failure to control thermal comfort in library
  zones
• Reduction
• Set up sufficient temperature and humidity
  sensors
• Model library in more than one program

12
Major Risks (continued)

• Errors in computer model
• Reduction
• Do sensitivity analysis on computer model
• Calibrate model with collected data
