Two questions, not one
Sustainability in exhibit design raises two separate questions. The first is about the exhibit itself: how much energy it uses, what it is made of and what happens to it afterward. The second is about content: how an exhibit about climate, nature or resources explains its subject accurately. They are related because an exhibit that preaches restraint while wasting energy sends a mixed message, but they need different kinds of care.
Where the footprint usually comes from
A digital exhibit’s environmental impact generally comes from three places, though their relative size varies by project.
- Electricity during use. Displays, projectors, computers, amplifiers and lighting all draw power for every hour they are on.
- Manufacturing the equipment. Producing screens, computers and metal or plastic enclosures takes energy and raw materials before the exhibit opens. This is often called embodied impact.
- Disposal and replacement. Equipment that is replaced early, or thrown away at the end of a show, adds waste.
It is hard to give general figures, because they depend on the devices, the electricity supply and how long things are used. If you want numbers for your own project, work from manufacturer data sheets and your own operating hours, and treat the results as estimates.
Reducing energy during use
The simplest step is to run equipment only when visitors are there. Scheduled startup and shutdown, motion-activated wake, and sleep modes during quiet periods can all help. Remote monitoring can confirm that the schedule is actually working, since equipment left on overnight is a common and invisible waste.
A hypothetical example shows how it adds up. Suppose ten displays draw 100 watts each, a total of 1,000 watts. Running 12 hours a day uses 12 kilowatt-hours, while running 8 hours uses 8, a difference of 4 kilowatt-hours a day. Real devices vary, so check actual ratings, but the principle holds: hours of use often matter as much as device choice.
Other practical choices include:
- Setting screen brightness to suit the room rather than leaving it at maximum. Managing screen glare with room lighting can allow a lower brightness.
- Using efficient display types where they suit the content, and avoiding larger screens than the content needs.
- Choosing media players that suit the workload rather than the most powerful machine available. Power-hungry computers running simple slideshows are a frequent mismatch.
- Using dark, simple interfaces carefully. On some display technologies, darker content can use less power, but this varies by screen type, so check before relying on it.
Materials and lifespan
Because manufacturing contributes to the footprint, keeping equipment in use longer is often among the most effective moves. That means choosing durable hardware, using enclosures that protect it, and planning for repair. A sound maintenance plan and attention to technology obsolescence can extend working life by keeping software and hardware compatible.
For physical structures, consider reusable or modular builds, simple finishes, and materials that can be separated and recycled at the end. Designing a show so that stands, frames and screens can move on to another exhibit is a form of sustainability as well as a saving. This links naturally with the approaches to touring exhibits, where reuse is built in from the start.
At the end of a show, plan what happens to equipment before it closes. Options usually include redeploying it, storing it, passing it on to another institution or school, or sending it for responsible electronics recycling. Small organizations in particular may find that small museums and community groups welcome a gently used display, though condition and compatibility should be checked first.
Content and file choices
Digital content has a footprint too, though a smaller one in most gallery settings. Well-prepared files, with sensible image resolution and compressed video, reduce storage and, for online components, data transfer. For web material, designs that work on slow connections tend to be lighter and use less data as well.
A reasonable rule is to avoid unnecessary features. A simple, well-made exhibit that does its job with fewer devices is likely to use fewer resources than an elaborate one.
Presenting environmental topics honestly
Exhibits about the environment carry a responsibility to be accurate. A few habits help.
Distinguish what is well established from what is uncertain. Say clearly where science is settled and where estimates are ranges. Avoid dramatic numbers without a source, and name the kind of source in the label (for example, a national statistical agency or a scientific assessment) so visitors can look it up.
Avoid greenwashing. Claims such as “eco-friendly” or “carbon neutral” are easy to make and hard to prove. If your exhibit uses efficient equipment, say specifically what you did, not that it is “green.” Mention trade-offs where they exist, such as the energy cost of the screen displaying the message.
Show scale and context. A single large number can mislead without a comparison. Present quantities with units and a reference point, and be careful with visual tricks that exaggerate differences. Good exhibit writing and clear motion graphics can help, as long as the graphic does not distort the data.
Balance worry with agency. Content that leaves visitors only anxious tends to be less useful than content that shows what individuals, communities and institutions can realistically do. Be careful not to imply that visitors alone can solve large systemic problems, or that they are to blame for them.
Respect local knowledge. Where an exhibit covers land, water or communities, consider consulting source communities and present their perspectives in their own words, with permission. Sensitive subjects such as disasters or displacement call for the care described under sensitive content.
Measuring what you claim
If you say your exhibit saved energy, record the before and after. If you hope it changed attitudes, test that with a simple method from visitor surveys or observation, and be modest about conclusions, since short visits rarely prove lasting change. Setting evaluation goals early avoids vague claims later.
