STRUCTURE COVERED BUILDINGS OF ENERGY RECEIPT

D E S e R 1 P e ION

OBJECT OF THE RNVENTION

The invention, as expressed in the statement of the present specification, refers to an energetic structure covering energy collection that contributes to the function to which several advantages and innovative features are intended, which will be described in detail below, which represent a remarkable Improvement of the current state of the art in your field.

More particularly, the object of the invention is focused on a structure whose purpose is to integrate both solar and wind energy collectors on one, two or more buildings, also fulfilling, when one or more buildings encompasses a reinforcing function when acting as armor of the buildings to which it encompasses providing them with anti-seismic properties, with the advantage that, on the one hand, solar collectors will be easily accessible to perform supervision and maintenance operations and, on the other hand, than with wind collectors, using the hollow spaces and the strong points of the structure (knots) on which

pivot, take advantage of the tunnel effect between the sunroof and the roof of the buildings.

In this way, thanks to the studied structural characteristics of the spatial design of the proposed structure, it allows to cover large lights and overhangs with little weight and high rigidity, allowing to have larger areas and open spaces that

they allow to easily integrate an important number of energy collectors, advantageously improving the conditions of energy self-sufficiency of the buildings and, therefore, of the cities.

FIELD OF APPLICATION OF THE INVENTION

The scope of this

The invention is part of the technical construction sector, particularly in the field of building, urbanization and city construction so that they are energetically sustainable, both from the energy point of view and from the mere

15 c onstructive, covering both objectives from prefabricated elements and subsequently assembled "in situ".

20 BACKGROUND OF THE INVENTION

The idea that human activity has a controlled impact on the environment and the community, guaranteeing its sustainability over time,

25 implies the need to conceive groups of people, whether in buildings, towns or cities, with other criteria. These groups end up becoming large consumers of energy, as is the case with cities.

The consumption of electricity in the home represents, in average terms, 35% of the total demand, increasing this percentage in countries closer to the Poles and as their quality of life increases. Of this 35%, demand peaks occur in the early hours of the afternoon and evening

coinciding with the hours of lunch and dinner being the highest peak two hours after sunset.

Sustainability, from the point of view of architecture, tries to achieve, through passive systems and non-aggressive assets with the environment, that the individual interacting with the building, obtain adequate levels of comfort and habitability. To achieve this, not only technically but conomically, governments encourage solar energy collection on facades and roofs, giving priority to the price of kWh exported to the grid, in the specific case of sensors integrated in the building.

Generating "in situ", just where it is consumed, means increasing the security of energy supply, reducing losses through Lransporte and improving respect for the environment by eliminating large transport networks.

However, to ensure the supply of electricity to buildings and cities, it takes more than a law that encourages the kWh collected and exported to the grid.

On the one hand, the areas that can be used in buildings for solar collection are reduced to that of roofs or terraces, since the walls, only the medium-to-solar orientation would be usable, and solar collectors do not perform well in position

vertical,

with the which he only space Really

They are the covered. Without embargo the

buildings,

in special in the city, they have a lot

surface

enough so that the energy to be captured represents a significant part of the demand of the building itself, with which the policy of prioritizing the kWh captured and

time with maximum demand (late afternoon hours) so it will be necessary to find technical and architectural solutions that allow to expand the catchment areas to capture more energy, store it during the hours of more availability to have it when need, that is, during the peak that is generated in the evening.

On the other hand, the use of wind energy on buildings is, until now, a pending subject. The integration of both types of energy (solar + wind) in the same structure that also forms part of the building's own resistant structure, increases its stability and the security of energy supply to the building.

Thus, the objective of the present invention is to provide an innovative structure for building structures in which the criteria set forth above are integrated, and it should be noted that the existence of any other invention is unknown by the applicant. solution elaborated on the basis of these premises, nor based on these principles that present technical, structural and constitutional characteristics similar to those presented by the structure described here.

EXPLANATION OF THE INVENTION

Thus, expanding the catchment areas is to talk about expanding the available terraced areas

or covered without logically damaging the stability of the building. On the contrary, the most interesting thing is to take advantage of the new roof to increase the stability of the buildings it covers.

To increase the area, it will be necessary to cover common areas between buildings or outside the buildings by cantilevers. To increase stability, instead of supporting the entire structure on a building, we must do it on two or more buildings provided that the structure is continuous, rigid and of low weight that also exerts low wind resistance and is capable of overcoming large overhangs and lights Between supports. These characteristics correspond to those of a spatial structure design. The recommended structure based on the union of bars by means of knots forming pyramids of square base, juxtaposed, and sides formed by equilateral or isosceles triangles, meets the characteristics listed above.

TO

its time its design condition that the

distance

between the props from bliss estruct ura

(columns)

match with multiples integers from the

equidistance between nodes of the structure. Therefore the design of the resistant structure of the buildings is conditioned by the spatial structure whose distance between columns will be integer multiples of the equidistance between nodes. At the same time, the union between nodes and columns will be adequately sized, so that it is a "structural whole" that assembles the entire structure of the building from the top and when it is a structure that encompasses one, two or more buildings, will improve stability. of the set thus providing seismic constructions.

Since the recommended structure is formed by a set of tubes joined by their ends forming pyramids whose vertices are outdated and juxtaposed, you can take advantage of the design of its upper base (squares) to inscribe solar panels that will constitute a sunroof. As the panels require periodic cleaning it will be convenient to look for a fixing system that allows accessibility.

The most appropriate will be to fix the panel frame

or hinged panels on the sides that form the upper base of each pyramid, so that as a window sheet you can fold down and facilitate cleaning. As the operator will have to walk supported on the sides of the lower frames, with harness, which allows him to move and secure, it will be preferable that the bars that form the sides of the lower base of the spatial structure are of square structural tube, to thus offer a flat surface of support to the feet.

For its part, the height of the structure, that is, the distance between its upper and lower bases, will be such that a man can travel between these bases and access the handle or bolts that open the panels' frames. The latter may be supported on legs that, in turn, are fixed on the lower base knots. All the nodes of the structure will be drilled in its vertical axis to serve as supports for legs or turbines.

In this way we will achieve the objectives outlined above, that is: increase in the areas available for greater solar collection, increase in the stability of the buildings covered and armed by

the

est ruct ura, low resistance to the wind, easy

integration

from the capt adores fotovolt penthouses Y good

accessibility

to the same.

Another characteristic of the structure proposed by the invention that is interesting to highlight is the large volume occupied by its gaps or empty spaces. These spaces will be used to place wind turbines that, working confined between the sunroof and the roof of the building, capture wind energy without disturbing the capture of solar origin, resulting in a hybrid energy system integrated into the same structure.

This provision will be adequate, for example, in places in the tropics where there are usually many hours of sun and its zenith close to the vertical of the place, thus prioritizing solar uptake over wind. In other locations, for example, outside the tropics or where it is of interest to prioritize wind uptake over the solar, distributed wind turbines as more interest may share the roof with solar collectors, in this case their rotor diameters and by both its power could be greater.

The wind turbine model that preferably incorporates the proposed structure starts from a self-tuning boomerang-like structure, which pivots recessed from a knot of the upper base of the structure, aided by a rudder. Said design allows the axis of the rotor rotation plane to be located on the same pivot axis. This solution eliminates gyroscopic effects and takes full advantage of the hollow space occupied by the turbine rotor.

It is, therefore, a structure that integrates within its volume two types of energy, solar on its roof and wind inside. This hybridization will help

to

decrease he volume of the system from storage

(batteries

or supercapacitors), etc. ) increasing the

security of

supply.

Likewise, the existence of a control and communications system that is responsible for managing the destination of the collected energy is contemplated, managing the whole according to the energy available at each moment, the demand and the state of charge of the batteries , that is, to decide if the energy generated at any given time is destined for the consumption of the building itself or buildings # or to complete the storage and / or sale ar ed.

For the sizing of energy storage, it will be based, preferably on a specific computer program, such as the so-called "HOMER" prepared by the NREL company, with the appropriate modifications to the application, in which it is prioritized to look for the maximum amount whose flows Economic funds could be used to finance investment.

Therefore, it is verified that the oversized solar roof with respect to the buildings' own demand together with wind integration and energy accumulation allows to achieve the objective of obtaining energy-sustainable cities by taking advantage of the common areas between buildings such as squares, parks or recreation areas, covered by structures such as the one proposed here, energy generating surfaces that represent an innovative concept of energy and architectural integration that, thanks to the accumulator system and the program

computerized will allow an energy availability that represents a new concept in the way of integrating and taking advantage of renewable sources.

The described cuhreedificio energy collection structure represents, therefore, an innovation of structural and constitutive characteristics unknown up to time for the purpose for which it is intended,

PREFERRED EMBODIMENT OF THE INVENTION

In view of the aforementioned figures, and according to the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.

Thus, as can be seen in these figures, the energetic collection structure covered by the invention consists of a tubular structure (1), based on a spatial design formed by juxtaposed square-based pyramids, whose edges converge in knots (5) of union of the different tubes that conform it, which is eminently designed and intended to be incorporated on the roof of one, two or more adjacent or nearby buildings (2), and within whose volume two types of energy collectors, collectors are integrated solar (6) and wind collectors (7), without discarding the possibility of

only have one type of them, that is, only solar collectors or only wind collectors, said collectors being trained not only to supply the energy demand of said building or buildings 5 (2), but also to accumulate the excess energy and dispose of it at the time of greatest demand, or to sell it to the network, counting for them with the connection of said sensors (6, 7) to the elements conventionally necessary for it as well as to a

10 computerized control system.

It is also important to note that, when the structure covers one or more of a building (2), it constitutes a structural reinforcement that provides the whole

15 of greater stability and anti-seismic properties.

The solar collectors (6) are integrated into the square frames that form the upper base of the structure (1), being tied to its sides

20 articulated by hinges (8) and bolts, so that they form a practicable sunroof, an articulated leg having support for solar collectors having been provided on the lower base knots.

25 For its part, the knots (5) of the structure

(one)

they serve as support and pivotal support of the gondolas

(9)

of the wind collectors (7), which, in the form of a bent tube like a boomerang, integrate into

30 its lower end is the generator (10) and the turbine rotor (11) which rotates describing a plane whose center of rotation is in the orientation axis on which it pivots, assisted by a rudder (12), thus eliminating the gyroscopic moments.

35 It should also be noted that said turbine (ll)

it will preferably be a microturbine and that. The wind collectors (7) are preferably arranged, alternatively, occupying the hollow spaces of the spatial structure (1) being located between the roof of the building (2) and the upper base of the structure (1).

Also, when interested, the wind collectors (7) may be located outside the structure (1) mounted on the nodes (5) of the upper base, properly distributed on its upper base, alternating its spaces with the sunroof, or over the overhangs, to prioritize wind uptake over solar.

On the other hand, it should be noted that the inclined tubes or crossbars (13) that join the upper and lower bases of the structure (1) are dimensioned in number, in addition to supporting the structural loads to be supported, so that the wind causes the smallest possible wake to. pass between them, in order to improve aerodynamic behavior in turbines (7).

Likewise, it should be noted that said crossbars (13) and, especially, the forming tubes of the lower base of the structure will preferably be of

section

quadrangular for to ease he displacement

and / or maintenance.

Finally, it is important to note that, preferably, the separation between the nodes (5) that are part of the lower base of the structure (1) determines the existing separation or that is given to

the columns (4) that form the structure of the building

(2), on which the structure is fixed, encompassed and assembled, so that said separation must be integer multiples of the separation between nodes (5) of the structure (1), resulting in a "structural whole."

In accordance with Figure 1, it can be seen how the recommended structure (1), in a specific example of embodiment of the invention, is installed so that it covers and encompasses two contiguous buildings (2) of four floors of the height, whose intermediate zone is take the opportunity to locate the common stairs (3) that give access to each floor. The columns (4) of both buildings (2) are equidistant, keeping three distances between

knots (5) of the structure (1).

The photovoltaic collectors (6) that are hidden by the bars of the spatial structure are located in the upper base of the structure (1). From the upper nodes (5) and alternatively, the wind turbines (7) occupy the hollow spaces between bars of the structure, at the rate of four rows of four turbines on each building (2) that will total 32 turbines throughout the structure .

In this specific example, the separation between columns (4) of the building (2) will be 7m, each of the buildings having four floors of 196 ml, which will house two houses of 98 ml, per floor. The set will have 8 + 8 16 homes of 98 ml. The structure (1) will fly on each side of the building 4, 66 m, equivalent to two inverted tetrahedra, having a total area of 44, 32 x 23, 32 1033, 5 ml, where the solar collectors (6) will be installed, whose panels will occupy 80% of the total, which is at a rate of 130 Watts / ml, an installed solar power

1033, 5 x 0.8 x 130 107.484 Watts. If the building is located in an area of the planet located

between

tropics We consider a potential from 1300 hours

the Energy annual captured by he ceiling

solar would be:

1300 x 107, 484 139, 729 kWh.

The diameter of the rotor (11) capable of rotating within the volume occupied by the gaps of this structure (1) shall be 2, 2 m. This rotor working at A = 4.5, will rotate at 508 rpm, when the incident wind is 13 mIs, driving a permanent magnet generator (10) that would give an instantaneous power of:

2,233 Watts ~ 2.2 kW

Being 0 = rotor diameter in ro v = wind speed in mIs

Considering a site of regular wind potential with 1200 equivalent hours, the 32 wind turbines (7) will produce an annual energy of:

32x2,2x1200 84,480 kWh./year

10 Once the annual available energy is verified, we will compare it with the demand of the building in order to evaluate the energy balance.

In any case it will be housing

For t ant or if the available energy amounts to

179,637 kWh / year and the energy consumed amounts to

64. 073 kWh / year, the energy to be exported will be 115,294 kWh. /year

This represents a very positive energy balance and can export the remaining energy.

If the example used had corresponded with the element or represented in figure 2 to the result previously expressed and expressed, it would be necessary to increase by 68% more, since, as observed in said figure 2, the example represented in it consists of a structure (1) that encompasses two buildings (2) of the same characteristics as those in the example of figure 1, but in this case faced and separated by a busy road, and in which the dimensions of the

The structure with respect to the number of dwellings in the buildings is much higher (28 openings instead of 19), which represents 68% more, on the previous example, of energy surface. Outside the volume of the

5 structure, 7 rows of wind turbines have been arranged above its upper base. This alternative will be the most appropriate when seeking sustainable cities.
