Mt. Angel Abbey 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 LibraryThe 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

The IssueThe 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)”

The IssueThe Issue• Occupant discomfort in :

Carrels, Auditorium, and Catalog room.

The SolutionThe 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.

PDSPDSPrimary 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)

PDSPDSSecondary 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 RisksMajor Risks• Failure to control temperature and humidity in vault and other

rare 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

Major Risks Major Risks (continued)(continued)

• Errors in computer model

Reduction: Do sensitivity analysis on computer model Calibrate model with collected data
