Aware Project by the Interactive Institute

AWARE is a design oriented research project that aims to increase people's awareness of how energy is being used in everyday life, especially in our home environment. The objectives are to develop strategies and artefacts that make people attentive of their energy use, as well as offer them control and possibilities of making their energy use more efficient.



The Aware project consists of six objects: a clock, light switch, chandelier, radiator handle and two lamp designs. The Laundry Lamp and Energy Aware Clock are currently on show as part of an exhibition called Visual Voltage at the House of Sweden in Washington.

The Aware Laundry Lamp (above) aims to encourage people to hang-dry their clothes as opposed to using a tumble dryer, one of the greatest consumers of energy in the home. Clothing hung on the frame diffuses the light and acts as a lamp shade.

The Aware Chandelier (above) explores the aesthetic qualities of compact fluorescent light bulbs.

The Energy Aware Clock displays household energy consumption in real-time and allows comparisons with the previous day’s consumption to be made through overlaid graphic visualisations. It also functions as an ordinary clock.

The Aware Puzzle Switch (above) is a household light switch that aims to encourage people to turn off lights by exploiting our “built-in desire for order”. The puzzle only appears complete when in the off position.

The Aware Handle is a radiator handle with teeth in the surface, designed to be more comfortable to use when decreasing temperature than increasing.

The Share Aware Lights (top image) are a series of portable, radio-controlled lights which divide a fixed amount of energy between them. As one light is made brighter the other lights in the series dim to compensate.

How to Add Solar Power to Your Home

Adding solar power to your home does not have to be difficult, or expensive. By slowly adding in solar power to your home electrical system, you can slowly, and affordably convert your home to run from the power of the sun. Choosing appliances to convert first is a simple matter of figuring out which appliances you can benefit from having run on solar power.

1. Purchase a Watt -O- Meter

This little guy will tell you how much electricity each appliance or plug is using during the day, and can help you figure out what your power requirements are. 2-3 days to a week is a suggested time frame for your power usage survey per plug, so you can get an average usage over a few days time.





2. Purchase a solar array that is within your budget.












3. Purchase a Battery for Power Storage
The battery is the thing that will be supplying power to your appliance during the night when there is no sunlight. The battery (or battery bank) should be more than your daily Watt -O- Meter
value for amp hours.




4. Purchase a Sine Wave Converter (DC to AC Converter)
These can vary in price from cheap to expensive, but again, you should choose one that is within the Watt values you got from your Watt -O- Meter
.




5. Put it All Together
Mount the solar panels on your roof, balcony, or even in the backyard on the ground. Just make them stable and face them towards the South in Northern Hemisphere, & in the southern hemisphere, they should face North; with a tilt of 60% in the winter, and 30% in the summer for fixed installations. This page has some good suggestions for Optimum Orientation for Solar Panels.

6. Power it all Up
Connect the Solar Panel(s) to the Charge Controller and the Charge Controller to the Battery. Now connect the battery to the Inverter, and turn it on. If all is working fine, plug a small lamp into the Inverter, and turn it on. Your lamp should now be running on battery/solar power.

7. The Electrical Tie-In
From here, you can either re-route outlets, or whole circuits from your Electrical Panel Box to your Sine Wave Inverter, or you can run extension cords to the appropriate plugs (much more dangerous, but acceptable in short wire run situations.)
