With a challenge of creating regeneration and community development in Trent Basin, Nottingham, UK, which meets passive house requirements, the first stage winning proposal for Isover Multi-Comfort House competition focuses on the minimization of the A/V ratio of the building. Designed by Evgeni Leonov Architects, the egg shape is used as inspiration to this project since the egg is known as one of the most energy-efficient forms of nature. More images and architects’ description after the break.
Under the current economic pressure, cities are no longer able to develop the way they used to, especially in the regeneration of unused industrial areas, which have become increasingly in demand due to lack of housing and infrastructure. Although nearby, they represent disconnected areas from the city centers. Considering that city expansion and large regeneration schemes remain as unrealized masterplans due to shortage of public funds and lack of incentive to private initiatives, it’s now a challenge to devise schemes which could trigger progressive regeneration in harmony with existing urban structures.
From an environmental perspective, large amounts of infrastructure and many buildings, which could have been adopted and reused, have been destroyed. The destruction of heritage and memory, the environmental cost of willful demolition and the scale, speed of erection and brutality of the new are most of the time too much for communities to absorb. Therefore, revitalizing bits of the city that need repair, that need healing is becoming increasingly important
. Minimal external surface means minimal heat losses. Egg shape is used as inspiration to this project. As known, the egg is one of the most energy-efficient forms of nature. To make A/V ratio minimal, we blocked houses together, linked walls, chose effective dimensions, delete corners, using egg shape in section, and adopted form to site. The result is twice reduced A/V ratio (0,39). Isover materials used in proposal allow meet the Passive House standards – specific annual heat demand for the building is only 3.33 kwh/m2.
Another feature of the proposal is the design of sustainable neighborhood. Local community core is planned in the center of the development. The core is a common recreation space to all people living in the neighborhood. The common playground, swimming pool, garden and common underground parking is a cost-effective solution and as well the place for communication and socialization between the neighbors.
Sustainable community advantages: no cars inside the block, common underground parking with a common entrance, common opportunities for recreation – swimming pool, garden, playground, sustainable environment for common living, working and socialization, Built-in services in some homes: shops, galleries, offices, common space for picnics and celebrations, common kindergarten in historic building of Trent Villa.
