Public housing with zero impact located in beautiful Florence. The project will end within 3 years and the first zero impact building it will rise in the surroundings of Piazza Artusi and will house 39 accommodations. There will be playrooms and other public buildings a zero impact.
By 2014 a Florence the first will arise public house with zero impact. This new building is part of the city building plan for one Sustainable Development, developed according to criteria for full thermal insulation and with an energy requirement powered by alternative sources. The experimental building project of Casa S.p.A. it is divided into three buildings made entirely of wood: two for residential use and a third building for public use with a playroom.
The buildings a zero impact from Florence. The first building will rise in Piazza Artusi, will have six floors and will house 39 apartments. The second building will rise in via Traversari, will have four floors and will house six apartments. The playroom will be built in Piazza Gino Bartali and will be developed on two floors for approximately 600 m2.
The use of special materials such as insulated wood and cellulose fiber will allow natural ventilation and thermal insulation, which will result in energy saving, production of energy from renewable sources. The use of wooden cross-layered load-bearing panels has significant environmental advantages: they will allow faster construction times, by about half, thanks to completely dry construction and also a lower environmental impact in terms of CO2 emissions energy consumption and use of raw materials.
The wall structure will be made of wood to avoid heat loss, solar loggias will be installed in the summer to ventilate the house on hot days and to heat the air in the winter months. In fact, just to contain the energy consumption three large bioclimatic atriums have been planned in correspondence with the stairwells, with an external wall totally glazed and with opening slats.
During the winter these windows will be closed, to reduce the danger of energy-thermal dissipation and to accumulate passive heat due to the greenhouse effect. In the summer months, however, the casing will be completely open to encourage natural internal ventilation. In short, we are faced with an authentic jewel of green building!
In the zero impact buildings, ventilation towers will be installed to capture and introduce the air into an underground pipeline system that will allow summer cooling and winter heating. The building will be of energy class A + and will have a requirement of 12.04 kWh / sq m per year, thanks to energy systems from renewable sources and the little energy needed for self-sufficiency.
In summary, with the package of the building envelope in the 'basic' configuration, there will be a need for thermal energy, heating and cooling, equal to 38.22 kWh / m2 per year, but with the adoption of atriums-greenhouses, loggias-greenhouses and walls of trumpets and underground ducts and ventilation towers one arrives at a energy requirement total thermal equal to 12.04 kWh / sq m per year, only for heating as the cooling requirement is zero.
The bill collapses and at the same time the air quality improves. It is a confirmation of how sensitivity and environmental sustainability go in the direction of choices on a structural level with zero volumes. With this intervention, public housing will be at the forefront with a fort energy saving, class A, and 0 impact.
