Turkuaz Nacafi - Erik Zanetti
At the micro scale, the local heating and cooling is addressed by means of devices such as those developed by Carlo Ratti and the MIT Senseable City Lab. Both use movement and proximity sensors to understand the position of the person in space and therefore activate the proper device. The placement of these sensors needs to be correctly mapped in the building since three sensors are needed at the time to locate a person.
1. Local cooling is achieved by using evaporative cooling. This system requires a tank where to col- lect rainwater which is then sprinkled on a pad. By means of a fan air is then drawn through the pad and cooled air is created, which is then stored in a chamber. From this chamber a system of pipes brings to each outlet, which is free to rotate in multiple directions. In addition, electrical cables are required in order to power their movement. In order to create niches in the wall where to place the devices, the beams are thickened in cor- respondence of the devices.
2. Local warming is achieved by using a system of infrared lamps that, similarly to the local cooling system, are free to rotate in multiple directions. In order to create niches in the wall where to place the devices, the beams are thickened in cor- respondence of the devices.
3. Openings are differentiated between those solely for light and those that allow sight to the exte- rior. The former are smaller in size and more densely packed, while the latter are larger and more sparse. Enclosed surfaces are instead created by widening the beams.
Cables and pipes integration
These devices require pipes and tubes, whose location differs according to the production meth- od. In the case of laser cut they would be hidden inside the beams, whereas in the case of milling grooves would be cut on the sides of the beams. The latter is here showed.
