The architects were challenged to design a scheme which delivers the least A/V ratio of the building. The first stage winning proposal for Isover Multi-Comfort House competition includes a design proposal from Evgeni Leonov, which has given the scheme an egg-shape, the shape associated with highest energy efficiency.
The architect has designed the scheme in a way that it demonstrates minimum A/V ratio. To offer this, the houses have been blocked together, and walls have been linked. Attention was paid on the effective dimensions to further reduce its A/V ratio.
Egg-shape was used in the sections, with corners completely deleted from the houses. All these have resulted in twice the reduced A/V ratio (0.39). Further, the choice of materials as well as specific annual heat demand of 3.33 kwh per square metre allows Isover to meet the Passive House standards.
The Evgeni Leonov proposal also include a community core in the centre of the development, which will serve as the recreation space for the residents. The community core will consist of common playground, swimming pool, garden and common underground parking. No cars will be allowed inside the housing block. Various services, such as shops, galleries and offices will also be incorporated into certain homes.
