Watt-Lite by the Interactive Institute

Watt Lite by Loove Broms and Li Jönsson

Loove Broms and Li Jönsson of Sweden's Interactive Institute have devised a system of lamps that visually indicate a factory's energy consumption through spotlights.

The design uses three lamps in conjunction, with the diameter of the orange, blue and white projections indicating the maximum, minimum and current energy consumption respectively.

The relative sizes of the spotlights allow the current energy usage to be quickly compared to the maximum and minimum values of energy consumption for the factory.

The lights are currently being tested in eight factories across Sweden.

Here are more details from Broms and Jönsson:


Watt-Lite: Energy Statistics made more tangible in factories in Sweden

The Watt-Lite have the exterior shape of an over dimensioned torch and is delivered in a set of three. The size of the light beam projected from the torches indicates a company's electricity consumption in real time. The dimension of the spot-light expands and contracts during the day depending on the energy usage of the factory.

The dark grey Watt-Lite with a white projection is a real-time electricity meter providing instant feedback of the current electricity usage.

The light grey Watt-Lite with a blue projection and cable shows the smallest effect (min) used during the day.

The other light grey Watt-Lite with an orange projection and cable shows the highest effect (max) used during the day.

By using three torches that shine in different colours, the real-time consumption can easily be compared to the max and min values. The Watt-Lites can be used where seen fit; hung in their cables projecting on the floor as well as placed on there handles projecting towards a wall.

A regular torch shows what is hidden in the dark, the Watt-Lite shows the hidden use of electricity. Without passing any judgment of certain kinds of behavior the factory workers are given the opportunity to reflect on their every day actions, set goals and better understand the otherwise hidden world of electricity.

Research has shown that technical solutions alone will not suffice to reduce the environmental impacts caused by mankind. Changes in habits are very important factor in reducing our excessive use of energy. This holds true for all parts of society, the private home as well as for the industry. In the research project IndustryWise, conducted at the Interactive Institute, the focus has been towards industries seeking to create interest and engagement around the topic of electricity to reduce unnecessary use. In total 30 Watt-lites have been produced and are currently being tested by eight different Industries in mid-Sweden.

The Watt-Lite is designed by Loove Broms and Li Jönsson at the Interactive Institute.

The service was developed by the Interactive Institute in collaboration with Eskilstuna Municipality, Eskilstuna Energi och Miljö. The project was funded by the Energimyndigheten. The Industrial companies participating are: Nike Hydraulics AB, Alvenius, Eskilstuna-Kuriren Printing AB, Södergren Metal AB, Solo Mechanical Solutions AB, Car-O-Liner AB, CH & Industry AB Gense.

    So they are going to turn on lights to show how much energy they are saving….. grreeeaattt.

  • Josh

    Interesting that you an energy consuming light to educate on the importance of efficiently using electricity. What’s next? Pamphlets to tell us he importance of minimizing our paper comsumption? Otherwise pretty clever.

    @ josh and steve – I completely agree – if you are trying to make very big factories consume less energy, you should do so using only dry leaves and sticks that have fallen off trees naturally. Thank you for your insightful comments.

    Nice, but why not just read the electricity meter?

    seriously, I can't wait for this lame "green" fad to pass and people to come back to reality. I thought these days that consumers and people in general were more educated and could see through marketing schemes and clever ways to make a buck or grab some power.

    The way green has been laid out just about everything we do is harmful to the environment. So short of slitting our throats there is little we can do to truly be "green."

    • Steve

      Exactly… but more optimistically… We need a paradigm shift towards sustainability, not a patch-job using green gadgets.

    I think in a factory 'naked-lady' type poster that is covered by steam depending how much power is being used would help in saving power, it might also drop productivity drastically.
