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)
| 10
Types of Collection Spaces
▶ Exhibition
▶ Storage areas
▶ Cold storage

Helpful Tools: Zone Maps
| 25
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)

Risk Management: Options
Factors to consider:
▶ Timeframe
▶ Cost
▶ Impact
▶ Sequence/relationship with other options
▶ Goals/priorities preservation plan
| 45
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
Advocacy
With effective team management, you can:
▶ Define realistic, sustainable preservation and operational goals
▶ Reduce operational inefficiencies
▶ Reduce the number of human comfort calls
▶ Improve communication and understanding between collection and facility staff
| 49
Advocacy: Collections
Experiences Metrics
