A simple production methodology allows the production of this component even in small production plants, so as to be able to insert the new product easily into the portfolio of existing producers, without damaging the existing entrepreneurial fabric, indeed expanding its know-how. The study of the entire industrial cycle also makes it possible to minimize the environmental impact by assuming not a second life for production waste, but infinite lives in cyclic processes.
The idea of the product is embodied in a wooden panel that can serve as both a horizontal and a vertical closure, suitable for both structural use and use in the casing. Its particular shape makes it highly integrable with plant systems, simplifying their construction. The simplicity of installation makes realization quick and cheap. Compared to existing products, the characteristics of the product point in a significant way also to the saving of the components and to the analysis and optimization in the installation process.

LANDSCAPE ENHANCEMENT Through the enhancement policies of the landscape it’s possible to create an economic induced linked to the safeguard that can confine the advancement of the anthropized territory.
REFORESTATION Reforestation is the best remedy against soil erosion and prevents hydrogeological instability. The development of a wood supply chain would encourage the conversion of uncultivated and abandoned lands into the forest.
INVESTING IN THE INDUSTRY-ENVIRONMENT BOND Linking an industrial supply chain to an environmental process is the best way to create sustainable production and development, as the production phases will tend to follow the biorhythms and to shape the territory.

ABRUZZO
VOLUME OF SALE IN ITALIAN REAL ESTATE MARKET The temporal inhomogeneity of demand in the construction sector results in an incredibly variable volume of use. By simplifying the construction process it is possible to use unskilled labor, which can work flexibly in multiple supply chains.
HOURS OF BUILDING AID IN ABRUZZO Despite the increase in orders in the territory relating to the period following the 2009 earthquake, there has not been a recovery in employment at the local level, a phenomenon largely due to the use of extra-regional companies.

NON-SPECIALIZED LABOR The use of non-specialized labor increases the occupational flexibility of the industrial sector. In this way it is possible to cope with market variations efficiently, distributing operators across multiple production chains.
PRODUCTION SYSTEMS AND INDUSTRIAL CHAINS The production of a territory can no longer ignore the environmental context but must become an integral part of it, or a subsystem of it, positively influencing it and receiving advantages, triggering other secondary production systems and thus reducing economic and environmental costs, as well as creating a market internal that can provide a stable industrial subsistence base.
LIFE CYCLE ANALYSIS Every industrial product should be designed with the entire life cycle in mind: from the extraction phase of raw materials to disposal. Through the analytical phase it is possible to understand which are the critical processes so that the product can become less and less impactful.

Land used for grazing in the province of L'Aquila
The area used for grazing in the province of L'Aquila represents 44% of the entire agricultural area. Most of them are land located in the valley or on modest hills, which are difficult to raise by farmers.
Paulownia and Tea plantation in the Shandong region of China
The Shandong region of China is where the planting of Paulownia has had the greatest following. It is cultivated together with other crops [photo] or in pastures, since its leaves are attractive to sheep and cattle. It consolidates the soil, reclaiming it and enriching it thanks to its rich foliage.

The Paulownia, also known as the "princess tree", appears in Europe in the early 1800s, imported by the East India Company.
La Paulownia: History, Description and Vegetative Characteristics
The genus, which has been cultivated for more than 2600 years, but which began to be studied since 1972 by the Chinese researcher Zhu Zhao-Hua, was initially planted by Chinese farmers in order to protect crops from sandstorms and floods, thus ensuring excellent harvests. Technical Comparison Sheet
After years of research, thanks to the varietal selection, some characteristics that make it a plant for the future of humanity are recognized to this plant, thanks to its properties of development and regeneration. The studies had the purpose of adapting the plant to different climates with the aim of promoting its cultivation all over the world, both for reforestation, both for the use of wood and for energy.

without knots By pruning the trunk from the branches before lignification it is possible to obtain a wood without knots for a height of at least 6 meters. This allows to obtain a wood without defects upstream, without sorting and processing in the sawmill, considerably increasing the quantity and overall percentage of fine wood in the harvest.
for outdoor use Once dried, paulownia wood tends to keep its humidity percentage constant around 11%, a value that makes it unassailable by most of the typical pathogens of this material. Empirical tests [mostly historical artifacts in Japan] demonstrate the extraordinary resistance to atmospheric agents.

RADICAL APPARATUS
low conductivity The paulownia wood has a particularly low conductivity, with average values equal to about half of those found in other woods typically used in construction such as pine and fir. This performance would make it possible to significantly reduce thermal losses even with reduced building envelope thicknesses.
dimensional stability After harvesting, paulownia wood suffers in a very limited way from the phenomenon of wood shrinkage so that it can be almost neglected. Once the sawn pieces are obtained, they are particularly stable dimensionally, undergoing negligible variations over time.
inter-row crop The taproot roots allow the inter-row cultivation of other crops, excluding the arboreal ones and the grasses, as their root system could present problems of removal.
lightness The paulownia wood is particularly light in all its species and its varietal clones. This characteristic makes this wood the best in aeronautical applications, thanks above all to the remarkable relationship between lightness and resistance.
stabilizes land Extending in depth, the paulownia roots could consolidate the soils that are critical in the hydrogeological structure.
biomass The excellent calorific value of this plant makes it comparable to poplar, although it emits less ash and fine dust.
land remediation This plant is able to absorb large amounts of heavy metals from the soil and water contained in it, which nevertheless remain metabolized in the roots, not affecting the quality of the rest of the tree.

The rapid rotation plantations [KUP] represent a valid alternative to the woodland crops already present in Italy and could in the future become an important economic and environmental opportunity for the local productive tissues managing to start, starting from the woodland heritage, a series of production cycles virtuosos.

Comparison with Traditional Systems
Recycling and Decommissioning of Components
The underlying graphic clearly indicates how much paulownia wood can be decisive in achieving high thermo-acoustic performance, obtained however by laying the only construction element without further insulation or finishing work.
To privilege "reversible" construction techniques means to aim at the complete recovery of the building which can be totally disassembled in order to recover the components for other urban interventions. The absence of adhesives in the components makes any waste-to-energy treatment more sustainable.

Summary
ADVANTAGES - Reduction of the workings of the construction process
sealing tape
Each connection of the construction system is composed of staggered joint profiles and shear joints such as self-tapping TPS screws and improved adhesion nails. This makes the sealing tape typical of prefabricated panel building systems superfluous, in particular XLAM and MHM. Thanks to these design features, savings can be made in terms of construction site time and therefore labor.
Optimum air tightness thanks to staggered joints
glue
The solid wood boards that make up the building system panels are connected to each other by means of beech blocks previously dried and inserted at high pressure in undersized holes made in the boards. Once the pieces have reabsorbed the surrounding humidity, they will dilate by fitting into the boards, becoming integral with them. This system makes it possible not to use adhesives, making the envelope 100% breathable and hygroscopic, as well as perfectly suitable for waste-to-energy treatment.
Absence of adhesives thanks to the plug connections, therefore 100% breathability
insulation
The high thickness of the casing [360 mm] and the low conductivity of the paulownia wood allow obtaining high insolating performances [0.18 W / m2K]. This, at least in the climatic zones that characterize Italy, makes any type of insulation superfluous. A further advantage resulting from the absence of insulation lies in the homogeneity of the casing: this avoids the risk of interstitial condensation, as there are no variations in density and permeability in the section.
Transmittance value U 0.18 W/m2K
counterwall technological
The particular shaping of the edges of the building system panels are designed to create a network of horizontal and vertical channels inside the enclosure, connected to each other, even on several levels, without interruption. This makes the counter-wall unnecessary for housing the pipes typical of framed and solid wood systems [above all XLAM and MHM]. The whole net has a constant square section both vertically and horizontally 120x120mm, a dimension that allows the passage of any pipe.
Absence of technological counter-wall thanks to the network of infra-wall channels
thermal bridges
The insulating material nature of the wood and the particular joints that make all the fibers of the casing are perpendicular to the thermal flow effectively cancel any thermal bridge in the casing. Another fundamental aspect is the monomaterial nature of the construction system, whose walls, in solid wood, do not present differences in density and permeability, allowing the thermal flows to pass through the envelope in a homogeneous manner, avoiding the risk of partial wear of any external coatings .
Monolithicity and nature of wood lead to the absence of thermal bridges
vapor barrier
The generous thickness enhances the thermal and hygroscopic behavior of the wood so as to make the vapor barriers superfluous, usually installed in other homologous construction systems [XLAM, MHM] and not [framed structures] in order to avoid surface and interstitial condensation, depending on the presence in the outer layers of the section of less dense or less vapor permeable material. Without the vapor barrier the building envelope gains in breathability and the internal environment is healthier, with considerable labor savings.

Comparison with Traditional Systems
Delivery Type Telematic Application Completely reversible modular construction system in wood, formed by boards in spruce or paulownia wood, overlaid and cross-fiber warp, whose main elements consist of two types of panel, one that acts as a vertical structural element, the another that acts as a horizontal structural element (floor). A peculiar feature of this constructive system is the particular shaping of the edges of the panels which, after assembly, at the junctions, form internal and surface cavities having a homogeneous cross section both along the floors and along the vertical walls, so that the aforementioned channels are connected to each other both horizontally and vertically on multiple levels without interruption. This feature allows both the assembly of the entire structure from the inside of the same (without the need for scaffolding and only through dry mechanical connections) and the possibility of passing pipelines of technological systems considerably simplifying the work for the installation of the same allowing however their modification or removal in the simplest and fastest way possible. Should this not affect the structural response of the construction system, the panels and any other component of the system can be cut, re-shaped, milled in the surfaces directly in situ. The thickness of the panels and the construction wood allow excellent thermo-acoustic as well as structural performance, without any additional intervention.

Plant Network The assembly of the construction elements creates along the joints a network of channels inside the casing formed by vertical channels passing internally to the wall elements and by horizontal pass-through channels both along the internal surfaces of the horizontal elements and along the wall-floor node, with section quadrangular continuous and connected to each other without interruption. This internal network of channels is particularly useful in the design and execution of plant engineering works which can thus be designed and arranged in a manner similar to the concept of plug n play, with a drastic reduction in the timing and production of demolition waste.

Ecocompatibility
The seismic behavior of a building made with this construction system is typical of a box structure, with floor diaphragms and walls connected by staggered joint joints and metal mechanical elements, where the walls have the task of absorbing vertical and horizontal stresses such as vertical loads, wind and seismic stresses.
The remarkable thickness of the panel allows obtaining high thermo-acoustic performance, so as to be sufficient for the achievement of any energy containment objective without the addition of any type of insulation. The massive nature of the system is particularly beneficial in the summer thanks to the thermal inertia of its components.
The entire production process is designed through a holistic approach aimed at inserting into existing production and environmental fabrics: starting from forestry, component manufacturing of this construction system is designed to trigger a series of good practices aimed at strengthening the symbiosis between economic and environmental sustenance.

POSSIBILITY OF INTERVENTION
The simplicity of installation and assembly of the entire system is one of the keys to solving the problems, which are no longer negligible, of work in the construction sector. Simple assemblies in fact allow the use of unskilled labor perhaps coming from other production chains, which can work in this sector only when necessary, when there is a real production requirement of the building sector, thus avoiding thirty-year cycles of expansion and collapse of the real estate sector.

"NEARLY ZERO" WASTE
Trying not to produce waste is easier than looking for an ecological value. The high level of prefabrication, the completely dry assembly and the presence of arrangements for housing the systems reduce the need for building demolition on the building site to a minimum, minimizing the production of demolition waste from problematic disposal and saving costs transfer to landfills, in recent years still on the rise.

The rapid rotation plantations [KUP] represent a valid alternative to the woodland crops already present in Italy [fir, pine, beech] and could in the future become an important economic and environmental opportunity for local productive tissues, managing to trigger off the heritage woodland, a series of virtuous production cycles.

Forests can be considered real carbon sinks as the carbon dioxide absorbed by the foliage is broken down by returning oxygen to the atmosphere and storing the carbon in the plant. The use of fast-growing tree crops mixed with the care of existing woods can increase the amount of stored carbon and therefore not released into the atmosphere.
From here it is easy to deduce that managed forests cannot reduce pollution, but can mitigate it.

The Energy Problem Today energy is the voice of greater consistency in the vast majority of production processes. The environmental impact that energy expenditure may imply is directly related to multiple factors, one of which is the type of energy source. The reality of Abruzzo, in some ways better but substantially in line with the national energy landscape, presents a heterogeneous package but composed largely of non-renewable sources [over 54%] and imported, of which it is problematic to establish their nature [13%]. This means that even an energetically ecological form such as electricity loses its environmental compatibility, as it is produced through fossil fuel power plants [above all diesel] that act as enormous generators.

Significantly increasing the percentage of renewable energy is therefore the only way for electricity to truly become an environmentally friendly form of energy. This would also have a positive impact on the price per kW that could, in the summer season, combine zero cost with zero impact.
In conclusion, drawing on renewable energy sources taken near the air used is the best way to reduce the environmental impact of energy in the production process.

Decommissioning of the entire system by dismantling, recovering the metal parts and re-using the panels for a new building or thermovalorizing them
Recycling
1 panel 150x300x36 cm
Recycling and Decommissioning of Components The construction technique, completely removable, allows the complete dismantling of the building recovering all its elements. The metal connections can be completely recovered and reused or recycled through a new fusion. The wooden panel can be easily disassembledfrom artifact to end of life and reused in new construction sites as it is or after preparatory work. Waste to Energy
Thanks to the mass of the building component it would also be possible, where necessary, to obtain wood to be introduced into new production cycles.
In this way the panel or its derivatives would continue to act as carbon sinks.
Another possible process would be to prepare for the waste-to-energy process, even if in this case all the carbon stored in the wood would return to the atmosphere.

100% of the biomass needed for the district's needs can be recovered within a radius of 250 m by growing Paulownia to obtain biomass from uncultivated or abandoned land. The rest of the energy production can be used to reduce the dependence on fossil sources in the rest of the urbanized area, fed by the planting of paulownia, wood maintenance and the biogas produced by the phyto-purification plant.

PRIVATE PARKING: Using the example of the Bedzed project in Sutton, London the use of private cars is reduced by 70%, consequently the superficial quota destined to private parking is considerably reduced thanks to the intermodal use of alternative means to private transport such as cars sharing, bike sharing and public transport. In conclusion, this surface can be reduced by 70%. BIKE SHARING: Collective rooms on the ground floor are used for the storage and management of bicycles that can be used for individual mobility.
PHYSICAL AND ENERGETIC FACTORS
COLLECTIVE LAUNDRY: The presence of common rooms used as laundry influences positively both energy saving [as there are fewer machines but larger ones] and space available to tenants in their housing units.
NATURAL LIGHTING: The overall width of the transparent surfaces and the correct relationship between this and the volume of the rooms reduces daytime lighting requirements. NATURAL VENTILATION: The orientation of the openings and the layout of the rooms is fundamental for summer cooling.
NEIGHBORHOOD SERVICES COWORKING HUB: Environments used for collective work offer workstations suitable for professional activities or start-ups in an embryonic stage that cannot sustain the logistic costs deriving from entrepreneurial activity. COLLECTIVE STUDY: Environments used for the collective study in order to give the possibility to youth groups to interface with each other in the learning process.

>>CONCLUSIONS Conclusions on the Construction System Design and its Applications
GENERAL CONSIDERATION
IL COMPONENTE EDILIZIO
In a context of urban regeneration of the existing heritage, the use of a wooden building component was experimented hypothesizing its local production and the repercussions on the territory involved.

LIFE CYCLE The equivalent CO2 balance shows how sustainable the building component is compared to traditional productions. Two factors predominantly affect the result: the raw material chosen and the concept of the set chain. The wood used in the production processes fixes a large quantity of carbon removing it from the atmosphere, while the setting of the short chain in a radius of 50 km drastically reduces the pollution deriving from transport.

THERMO-ACOUSTIC The results and the stratigraphy of the building component show excellent thermo-acoustic performance, mainly due to three factors: - low material conductivity - thickness of the element - mass of the element These factors in fact make the workings typically required in high performance index walls [insulation, vapor barrier, etc.] superfluous. The comparison with a wall made with traditional technologies highlights the greater amount of work and the overall thickness of the latter.

-91% The production cycle of the Paulownia wooden building component was found to be sustainable as: - The nature of the raw material has resulted in a passive CO2 balance [-1272 kg CO2eq.] - The short chain has drastically reduced the consumption of fossil sources necessary in transport.
intervention: building envelope replacement
In the redevelopment of existing structures, the Construction System PE2014A000026 has proved able to adapt to the existing building heritage and its problems without losing the performance characteristics of the system. existing structure: reinforced concrete frame
It is therefore possible to upgrade existing structures to an optimal performance level, like a new generation building.

COSTS The computations of the construction costs of a building with this construction system show a cost reduction of 60%. The keystone of this result lies in the drastic reduction of work in progress: in fact, compared to a higher cost in the initial phase of raw production [63.10 € / m2] it becomes far more convenient in the finishing phase. The high installation costs of the insulation and the vapor barrier are reduced thanks to the high thermal and acoustic performance of the component, which makes any other type of intervention superfluous.
ENERGY The energy performances of the existing buildings redeveloped with this construction system show an optimal wrapping performance, where to the insulating power is added an excellent thermal inertia added to the complete wall perspiration, so much the demand is so small as to be able to hypothesize an under-sizing of the plants with respect to the standards. WATER The results of a correct sizing of a phytodepuration plant highlight the sustainability of this choice. The plant is able to cover most of the water needs of buildings, making it therefore a valid solution for water treatment in medium and small urban agglomerations.
RETRAINING From the project it is possible to understand the potential of the construction system even in redevelopment operations. The system was in fact tested both as a casing and as a prevailing thermo-regulating function, and as a "core" hosting the serving spaces of the rooms that were able to find in the underground channels great functional simplicity.
