The kindergarden draft design is based on a special energy saving proposal, aiming to achieve a reduction of 30% energy needs compared with a common Kindergarden, as well as enhanced comfort and spatiality. In this phase of the project have designed high spaces in order to allow natural air ventilation and illumination through them. An enveloping ceramic ventilated skin protects the interior of the building from temperature and noise and hosts solar panels on the south and windows on the north.
