Green roof: the urban nature and sustainable design

  • / “Ion Mincu” University of Architecture and Urbanism, Bucharest, Romania

Rezumat:

The link between man and nature, so suddenly interrupted within the city, gained an extra chance with the appliance of sustainable principles from which have resulted in large greenhouses on the top or on buildings facades, or the concept of green terrace, resulting in large surface of green 100% controlled by man. Restoring the link between man and the "natural" has beneficial effects on our health. This is visible by reducing stress, decrease muscle tension and obtaining a more relaxed and quiet environment that enhances social relations including the buildings.

Given the lack of vegetation in cities, the presence of green spaces on the top of the buildings alongside with public spaces produce positive effects in people's minds and on the economic layer. These spaces end up being put on the market more easily, being sold or rented at a better price because they are perceived as more pleasant and with the possibility of improving people’s mood. Giving up square meters of building area or greater investment in terraces and green roofs is a way to get spaces that are easy to rent or placed on the real estate market.

The emergence of green roofs allows solving issues of large horizontal surfaces, adding them an aesthetic value. Green roofs are used on a larger scale in order to lower energy consumption (by enhancing thermal insulation), reduces the heating effect due to large terrace areas and the reduction of the greenhouse gases effect.
