A few months ago Fujy of Barcelona inaugurated the pilot plan of the sustainable house.
Fujy, directed by Italian architect Luca Lancini, is dedicated exclusively to sustainable architecture and applyies one wide and articulated vision of sustainability in the building industry.
Besides the subject of planning energetically efficient buildings with low enviromental impact, Fujy introduces one virtuous dinamicity in the construction industry by choosing partners concerned in environmental sustainability.
The project demands as mandatory the environmental certificates now available in order to improve the productive chain and lower the nature impact.
Moreover a powerful campaign of envirormental awareness has been planned, in order to create environmental conscious customers, indispensable condition for the building industry to move towards sustainable modalities.
Another important point in the activity of Fujy is the collaboration with Public Institutions, O.N.G. and Universities for the creation of policies of sustainability.
The main target of the pilot plan of Fujy is to show an example of studied sustainable architecture. Fujy aims to demostrate that all necessary technologies for the creation of sustainable cities are already available and that difficulties for a sustainable conversion of architecture are mainly cultural and not technical.
In the pilot plan the architects underlined the three guiding principles of the study:
- "Goodness" that is social and envirormental awareness
- "Beauty", choice of contemporary languages that meet aesthetic and functional requirements
- "Benefit", the ability to create plans at competitive costs with low maintenance and operating costs.
The plan is a family house situated in El Escorial, near Madrid; it synthetizes the studies carried out in the last years on sustainibility architecture and is an example of a sustainable home.
The plan aims to insert armonically the structure in the land and adapt to the weather conditions answering with every facade at the specific situation given by the orientation and the land lottery conformation. The planning of external spaces aims to reduce the impermeabilization of the land by paving only the necessary paths with pine wooden plates.
The building is constructed with a selection of materials carefully chosen for their own low-environmental impact and for their specific thermal behavior. The structure is based on certified wood; the external wall envelope is constructed with blocks of termic clay projected by La Oliva company. The northern, eastern and the western walls are made of a cardboard plaster panel and recycled paper KNAUF, a layer of blocks of termic clay of 29 cm of thickness (which guarantees an acoustic isolation of 52dBA and a thermic trasmittance of 0.81 W/m2K), an inner tube of 5 cm and one external layer of 11cm of silicon-limestone blocks.
The southern side is built with blocks 14cm thick (wich guarantee an acoustic isolation of 46.5 dBA and a thermic trasmittance of 1.39 W/m2K).
The isolation cover is realized in GUTEX panels made of wood fiber, of the BioHaus company. The main characteristic of this material is the highly porous structure that concurs to a good spread of the steam and confers optimal acoustic isolation; moreover GUTEX panels don't need adhesive, have an elevated thermal inertia and are completely recyclable and compostable.
The design of the house respects the rules of bioclimatic and integrates the passive systems, i.e. the creation of a facade more isolated on the north side and of a greenhouse on the south.
Moreover a domotic system allows the building to adapt to external climate without demanding any excessive complex management, limitating wastes.
Heating is integrated: the air gets warmed in the greenhouse, heating the house for passive way in a good part of the year.
The propane high efficiency air conditioning system (CERASAMRT by Junkers) gets started whenever the domotic system relevates the necessity; heating is connected to radiating pavement.
Solar paddles can also be connected to the radiating pavement of UPONOR.
The disposition of the openings, which are also regulated by the domotic system, has been planned in order to guarantee crossed ventilation.
The sanitary warm water production is guaranteed by solar paddles SolarMaxiPlus of company VELUX, completely integrated in the design of the building.
The hydraulic system is thought in order to lower water consumption with facilities such as timed taps. It is previewed a system of collection of meteoric waters and a system of depuration of grey waters that feeds the reserviors of the toilets and the garden irrigation system.
The careful study of the natural lighting system allows a reduced necessity of artificial lighting system.
The electricity saving is also obtained by the use of high efficency lighting systems with passage sensors; all household-appliances are high energetic efficiency.
A solar clothes-dryer with opaque crystals is inserted in the inside of the south facade .
The materials used for the inside are chosen in function of the envirormental impact avoiding toxic product; most of these contains a percentage of recycled material, like walls and cardboard plaster false ceilings, with recycled paper.
Beyond the envirormental themes, Fujy aims to the social aspect of sustainability.
Therefore our architects target is the creation of the best confort and accessibility for all our clients.
