Adaptability has been in consideration while designing the floorplans. With a shared common space, kitchen and living room, every apartment has two units consisting of one bathroom, a standard bedroom and a smaller room for different purposes. These units are designed so that they can be used independently. These solutions together with the shared spaces at the roof top are meant to increase the social interaction and the usability of the rooftop extension in the long run.
The additional rooftop extension’s main material is wood, which benefits this particular project by its different capacities, considering the fact that it is relatively light-weighted which means less reinforcement on the existing building is needed. The walls are out of prefabricated solid CLT-elements, it stores more Co2 and the load bearing capacity of it is good enough to avoid thick wooden pillars.
Facades and the roofs are covered with translucent marble gold solar panels, to take maximum advantage of the location of the building but also to avoid overheating during summer.
Cross ventilation:
During summer, the heated air inside the courtyard leaves through the openings at top causing negative pressure which lets the cooled air from the courtyard, which is in shadow, breeze in through the openings at the bottom. The vegetation helps through evaporative cooling to cool down the air even more and contribute to a pleasant atmosphere inside the building.
During late winter/spring when the temperature outside is still below the comfort zone, the sun will heat up the courtyard through greenhouse effect, this heated air will be caught inside the courtyard (buffer zone) and used by the resilience if needed.
The apartments have a big opening towards the courtyard in order to take advantage of the natural cooling/heating system when convenient.
