ANTI-SEISMIC

The results of a study conducted by Prof. Franco Braga, Professor of Structural Analysis and Design at La Sapienza

University of Rome, Chairman of ANIDIS (Associazione Nazionale Italiana di Ingegneria Sismica/Italian National Association of

Earthquake Engineering), Member of the European Anti-seismic Commission and Member of the World Anti-seismic Commission,

have confirmed the earthquake-resistant quality of the IBS Construction System by Aurea.

ANTI-SEISMIC


The use of the IBS construction system involves a significant reduction of the structural weights, with consequent

reduction of the seismic stresses substantially linked to the forces of inertia and therefore the mass and weight.

With the IBS system from AUREA it is possible to obtain up to 30% savings in terms of weight of

the constructed building.

A careful energy design makes it possible to construct Class “A”, “A+” and Gold (Casa Clima) houses,

where energy efficiency means:

•High living comfort•High quality construction

•High real estate value of the building

ENERGYSAVING


The IBS building envelope plays an important role of a temperature regulator: the structural elements of which it is made make it possible to achieve optimum level of internal comfort and

low energy requirements of the building, so as to provide for the use of thermal installations with low operating temperatures and

electrical systems with low power consumption.

ENERGY SAVINGStratigraphic analysis of the

construction elements


ENERGYSAVING


For correct energy design of a building element it is necessary to evaluate the stratigraphy in order to determine the ideal thickness

of the component materials in relation to different climate zones.For Climate zone “E” taken as an example, the thermal features of the outer walls and slabs were calculated for a residential building

constructed using the IBS.

In the design of the energy efficiency of a building with the IBS system, hygrometric tests are conducted on the opaque parts of

the envelope, as required by Italian legislation, to avoid damage to the construction elements (walls, floor, roof) and especially in order

to check the condition of the air inside the building(Indoor environment quality).

No interstitial condensation was found inside the IBS outer wall and no surface condensation is generated since the dew point is never

reached on the inner surfaces of the construction element (IBS outer wall).

In terms of indoor environment quality, it was ascertained that conditions do not exist for the proliferation of fungal spores and the

spread of mould.



ENERGYSAVING


The structural elements of the IBS system are constructed on site: IBS means environmental safety.

A building constructed using the innovative IBS system is eco-sustainable not only because of the low CO2 emissions in

the atmosphere but also because of the low use of energy for the production, transport and disposal and recycling, if necessary, in case of demolition; careful analysis of the amount of embodied

energy was therefore used throughout the building construction process.

ENERGY SAVINGIBS sustainability:

Life cycle and embodied energy


ENERGYSAVING


Constructing a new building using the IBS system according to the principle of energy efficiency helps to avoid unnecessary

emissions of greenhouse gases into the atmosphere and makes it possible to avoid tapping into the ever dwindling supplies of fossil

fuel sources (oil, natural gas, gas and coal).The design, construction and use of a building in IBS have the

objective of obtaining an extremely low environmental impact taking into account also the maintainability cycles.

ENERGY SAVINGEnvironmental sustainability


ENERGYSAVING


The use in the IBS construction system of polystyrene, a material with remarkable thermal insulation and sound insulation properties

means that the houses constructed using this system are in accordance with regulations:

•Framework law 447/95, D.C.P.M. 14/11/97 •D.P.C.M. 5/12/97

SOUNDPROOFING

The IBS system uses four materials for the construction of the structure:

•Fibre-reinforced structural mortar •Electro-welded steel mesh

•“C”-shaped elements made of bent and galvanised sheet •High density polystyrene

The ease of assembly of all the elements, the standardisation of the materials used and the simplicity of the IBS system make it possible

to limit the construction times (A quarter of the time compared to the traditional system).

CONSTRUCTION SPEED

TIMESAVING


In the IBS building system, all the vertical and horizontal surfaces are connected to one another by means of electro-welded metallic

mesh, inside and outside the building and a structural mortar, creating a continuous, elastic and monolithic structure.

The resulting structure is like a shell, or even better a tree, which, through a mixed structure with a high level of elasticity, owes its

resistance to the entire set of its elements.

ANTI-CYCLONE

ANTI-CYCLONE


The structure of the IBS system possesses a strong elasticity modulus also in the presence of extraordinary

atmospheric events such as cyclones.Owing to its high dynamic compensation index, the structure is

able to withstand hard knocks and the water hammer caused by stray bodies and scattered vectors.

ANTI-CYCLONE

ANTI-CYCLONE


The load-bearing structure is self-protected with a fire-resistance REI 120.

The materials used are all Class “A” and therefore self-extinguishing.

FIREPROOFMaximum Safety

FIREPROOF


The IBS construction system is economicalcompared to the traditional system due to:

•Lower labour costs•Low cost of materials used with better final quality

•No machines or fixed installations required, no heavy handling operations on site

•Reduction of insurance costs•Lower safety costs

•Reduction of investments risks and financial exposure
