    Environmental Management: Phases

    ▶ Set-up

    ▶ Understand the problem

    ▶ Why is the environment important?

    ▶ Assemble documentation

    ▶ Build team

    ▶ Define objective

    ▶ Deploy instrumentation

    Building and Room Envelopes

    ▶ Heat loads and sources of moisture:▶ Solar load

    ▶ Transmission through exterior

    ▶ Infiltration from surrounding spaces

    ▶ Openings (windows, doors, holes, structural design)

    ▶ Construction materials

    ▶ Presence of insulation, vapor barriers

    ▶ Within space (lights and electronics, people)

    Types of Collection Spaces

    ▶ Exhibition

    ▶ Storage areas

    ▶ Cold storage

    Zoning issues

    ▶ Multiple units that serve one space

    ▶ One air handling unit serving both occupied spaces and

    collection spaces is not recommended

    ▶ Directors office, restrooms, galleries, server rooms, etc.. tied with

    collection spaces

    ▶ Staff offices in collection spaces

  • | 26

    Human Comfort Control Issues

    Human comfort requires different conditions than collections

    Human comfort, according to ASHRAE: ▶ 68-75°F in the winter

    ▶ 75-80°F in the summer

    Collections need cooler conditions

  • | 27

    Define Objective

    Data Analysis

  • | 28

    An optimal storage environment is one that achieves the best possible preservation of collections with the least possible consumption of energy, and is sustainable over time.

  • | 29

    Extremes

    ▶ What: highs and lows of temperature and relative humidity

    beyond what is usually experienced in the space

    ▶ Where: unconditioned spaces, lack of environmental

    controls, areas with additional loads, change in operation

  • | 30

    Extremes

    ▶ How to Identify:

    ▶ Reports from staff

    ▶ Temp gun

    ▶ IR camera

    ▶ Environmental data

  • | 31

    Extremes▶ Consequences: Accelerated chemical deterioration,

    increased risk of other forms of damage; operational costs

    ▶ Mitigation: Depends on cause▶ Secure building and room envelope

    ▶ Reduce moisture loads (landscaping, outside air)

    ▶ Reduce heating and cooling loads▶ Use shades, etc.

    ▶ Remove occupancy

    ▶ Reduce lighting

    ▶ Relocate/ buffer sensitive materials

  • | 32

    Harmful Microclimates

    ▶ What: The climate of a very small or

    restricted area that differs from the

    climate of the surrounding area

    ▶ Where: By supply diffusers, within

    compact shelving, against exterior

    walls/windows, inside containers, etc.

    ▶ Any place where differences exist

  • | 33

    Harmful Microclimates

    ▶ How to Identify:

    ▶ Reports from staff

    ▶ Temp gun

    ▶ IR camera

    ▶ Environmental data

    ▶ Anemometer

    ▶ Moisture meter

  • | 34

    Harmful Microclimates

    ▶ Consequences: Mold outbreaks can

    occur, increased risk of other forms of

    damage; operational costs

    ▶ Mitigation: Depends on cause▶ Arrange boxes and storage furniture to

    promote air mixing▶ Identify and eliminate sources of

    dampness▶ Relocate/ buffer sensitive materials

  • | 35

    Sustainability ▶ Depends on:▶ Local Climate

    ▶ Building Envelope

    ▶ Mechanical System

    ▶ Collection Needs

    ▶ Institution’s Goals

    ▶ Achievable with:

    ▶ Knowledge of Collections

    ▶ Team Approach

    ▶ Reliable Data

    ▶ Experimentation

    Risk Management: Teamwork

    Team members:

    ▶ Those who create the environment (Facilities staff)

    ▶ Those responsible for preservation of collections (Collections staff)

    ▶ Those who work in and around collections (Curatorial, Interpretation)

    ▶ Those responsible for administration and finances (Administration, Finance)

    ▶ Those who direct the sustainability mission and goals (Sustainability officers)

    Institute Actions

  • | 46

    DO:

    ▶ Assemble Documentation

    ▶ Collections

    ▶ Building Envelope

    ▶ Mechanical System and Downstream Equipment

    ▶ Build team

    ▶ Define objective

    ▶ Deploy instrumentation

    ▶ Begin data collection, analysis

  • | 47

    DO NOT:

    ▶ Institute certain actions without awareness of the consequences

    ▶ Open windows

    ▶ Install window A/C unit

    ▶ Arbitrarily lower temperatures

    ▶ More outside air/economizer

    ▶ 2012 Energy Conservation Code recommends an economizer to be capable of supplying 100% outside air

    ▶ 5°F temperature dead band

    ▶ Can lead to significant change in RH

  • | 48
