Invisible information a) The amount of traffic at peak hours and the average delay because of the traffic jams b) The amount of sunlight during the day in the beginning of February 3. Case -> how invisible information can become knowledge and contribute to the planning of a more livable urban space. Let us take the amount of sunlight during the day in the beginning of February: it can help us calculate if it would be possible and profitable to install solar panels to extract energy from the sunlight for the needs of the city or the particular building. To make this decision we will also have to consider other information, such as the amount and type of fall-outs, construction of the buildings to see if they are suitable for solar panels instalments, etc. All this information combined and analysed will provide us with the necessary knowledge about energy consumption in certain area and how we can meet energy requirements while using more clean energy.
