1. Introduction
Currently, there is a wide range of commercial BIPV products in the PV market. But up to
day the almost totality of BIPV products are conceived only as PV units conveniently adapted
to the use for building integration. One of the most remarkable aims of BFIRST project is the
consideration of the double energy & constructive functionality facets of BIPV from the
earlier steps of design and development.
The catalogues of BFIRST project will be preferentially aimed to architects and construction
professionals. From this point of view, the constructive functionality of the BIPV units
acquires a notable relevance, because architects and construction technical (often with limited
knowledge of photovoltaics and specific requirements to develop their building works) will be
able to access quickly and easily to the available BIPV solutions. In the other hand, the use of
the fibre-reinforced materials as matrix for the PV cells array encapsulation adds an important
innovation factor to the adaptation of BIPV products to the varied range of the architectural
scenarios. These and other aspects has been deeply worked during the design stage and
thoroughly discussed between the consortium’s partners involved in “WP2. Development of a
BIPV elements portfolio”, in order to get a good set of products for cataloguing and
demonstration aligned with the project targets and the possibilities of the demo-site buildings.
During WP2 in the framework of BFIRST projects, and taking into account the above
resolutions, it will be conceived, designed and characterized the set of Building Integrated
Fibre-Reinforced Solar elements which will make up the portfolio of products.
BFIRST designs have been thought up within WP2 to achieve double-functionality energy-
construction elements for building integration in several architectural units: façade, roofs and
closings. These will be based on fibre-reinforced encapsulation technology, which will be
developed and tested in lab during the execution of WP3; and subsequently manufactured,
installed and demonstrated under real conditions at pilot scale in demo-site buildings within
WP4 and WP5. Finally, the whole of designs, as much the conceptually developed as the
prototyped ones, will be gathered together with their technical specifications in the catalogues
and guidelines of WP6. The right focus of the catalogues will decide the success of
dissemination and exploitation of the results within WP7.

2. Objectives
The main actions in the framework of Task 2.2 WP2 are the conception of the ideas which
preliminary designs are based on, the execution of such designs and the selection of those set
aside for demonstration. During Task 2.2 it has been proposed ideas according to the original
targets of the project regarding products to develop: fibre-reinforced matrix; monolithic
structures; light weight; standardized, modular and flexible in shapes, up-scaling
manufacturing, easy setting up, competitive price, etc.
The main goals of Task2.2 are to achieve a complete set of products based on the above
requirements and grouped by families, in order to cover the wide range of applications for
BIPV. Partners involved in design stage have taken into consideration these and other
subjects, as well as the viability of selected products setting up at demo-site buildings. The
designs showed in this document and Annex attached has been analyzed from the point of
view of photovoltaics and architecture. All this efforts are addressed to ensure the multi-
functionality of BFIRST products, as photovoltaics generation and construction units, one of
the most important objectives of the project.
An additional aim has been assumed during the execution of this task: guarantee the quickly
and easily introduction of the products designs and the technical characteristics into the
structure of portfolio. This purpose will allow the execution of a high quality and versatile
catalogue and guidelines for architects, constructers and any other stakeholder. The planning
of technical templates to characterize each product is conceived aligned with this target, since
these data-sheets will be gotten the technical specification of final products of the catalogue.
In the other hand, geometrical design of products has been developed from the beginning in
CAD format in order to make easy its implementation in Building Information Modelling
tools (BIM).
Up to day, it goes on open the debate around the products proposed for cataloguing and
demonstration; and a deep and interesting discussion are taken place between the partners
involves, not only in the design process but also in the demo-sites setting up. The objective of
generating a dynamic work forum, where to reach a consensus about every option of BFIRST
product and demonstration, has been really success as will be explained in the next chapter.

3. Description of work
3.1 General distribution of work
The deliverable “D2.2 First selection of BIPV products” is the first one of the “Task 2.2
Contents of the portfolio” within the “WP2 Development of a BIPV elements portfolio”.
ACCIONA is in charge of leading this work package and all its tasks, and together with
TECNALIA, BEAR and ATERSA, of carrying out the works planned for them.
The distribution of responsibilities was thought to develop the ideas of photovoltaics building
integration taking into account simultaneously the double constructive and energy
functionality of products from the preliminary designs. In this regard, ACCIONA and
TECNALIA assumed the work to conceive the ideas and to carry out a first version of each
design. Afterwards, BEAR and ATERSA provided support to the theoretical validation,
improvement and extension of proposed designs; by means of both analyses from the point of
view of architecture and photovoltaics disciplines, respectively.

3.2 Activity planning
The activity throughout the first phase of Task 2.2 has followed the next planning:
• Preliminary designs of BFIRST products: it was generated an “Idea Template” with a
fulfilment guideline to show the preliminary geometrical designs and main material and
functional characteristics of BIPV products (see “Figure 3” of Section 3.3 of this
document). ACCIONA and TECNALIA developed and proposed several original designs
for the portfolio of products.
• Selection of BIPV products: the proposed ideas were discussed between the partners of
consortium during the General Assembly Meeting, celebrated the 3rd and 4th of
December 2013 in Madrid. As a result of this debate 11 preliminary designs were chosen
to be included within the porfolio of BFIRST products; some of which were selected to be
prototyped and tested under controlled and real working conditions in labs and demo-site
buildings.
• Analysis of BIPV products: the proposed ideas were analysed by BEAR and TECNALIA,
under architectural and photovoltaics criteria, giving their opinions and suggestions about
the preliminary designs proposed by TECNALIA and ACCIONA. The subjects of these
analyses were the following: geometrical design, manufacturing materials, electrical and
structural configurations, etc.), as well as proposals of families of standardized products
based on the preliminary or advanced designs.
• Technical templates for the characterization of BFIRST products: the rest of labours
within Task2.2 were focused to generate a set of technical templates aimed to gather every
technical specification regarding the BFIRST products in order to make possible the
creation of the sheets for the catalogues. A “Generic Technical Template” was elaborated
with this purpose (see “Figure 4” of Section 3.3 of this document).
3.3 Documentation
Product’s designs and specifications will be reviewed, corrected and improved several times
throughout the execution of WP2, based on the conclusions of architectural and photovoltaics
analysis, and other considerations coming from the requirements imposed by the BFIRST
demo-site buildings, the results of the developments in lab testing, the manufacturing
limitations, etc.
Specifications of every product selected will be defined through the completely filling out of
technical templates at the end of the Task 2.2. The set of technical cards for each product will
constitute the Product Folder. The collection of every product folders will form the Product
Portfolio, which will be showed in a first version within the deliverable “D2.3. Specifications
for every product selected”.

Product folders will be finished taken into account the conditionings mentioned above during
the “Task 2.3 Detailed design of BIPV elements”. The final version of the Product Portfolio
will be published once finished the WP2, with detailed designs and simulations of those
products selected for demonstration.
A basic scheme of the documentation generated during the carrying out of the WP2 is showed
in the following figure:
Figure 2. Documentation generated throughout Task 2.2.
The information contained in the final version of BFIRST Portfolio of Products will be used
to manufacture the prototypes and setting up them at the demo-site buildings. It will be also
the main information source to make up the BFIRST catalogues and guidelines during the
execution of WP6.
The first documents needed to carry out the WP2 were the “Idea” and “Technical” templates.
In the next sections both of them are attached.

FULFILMENT GUIDELINE OF IDEA TEMPLATE
Fulfilment of Idea Template.
• Idea Template has been conceived to show in a quick and effective manner the products proposals, in
order to be evaluated by members of the consortium involved in Task 2.2.
• Explanations of different features of the proposed ideas must be more descriptive than numeric. Once
decided the set of products that will be included in the portfolio, they will be numerically characterized
during Task 2.3. Illustrations are also important, try to show graphically as detailed as possible the
geometrical and material configuration of the BIPV unit and integration procedure.
Generation of Ideas.
• Designer partners will have to propose at least five BIPV elements; one per every category including
in BFIRST portfolio, and fulfil an Idea Template for everyone:
- BIPV Curtain wall unit.
- BIPV Ventilated façade unit.
- BIPV Skylight unit.
- BIPV Roofing shingle unit.
- BIPV Shading system unit.
• Common characteristics to all the elements:
- PV Encapsulating must be executed by the method based on fibre-reinforced composite materials
developed within BFIRST project.
- BIPV units must have constructive and energy multi-functionality.
- BIPV units should be able successfully integrated in architectural environment and submitted to
aesthetic criteria of design.
- BIPV units should be able to meet the UE standards according to the Construction Products
Regulation (305/2011/EU-CPR).
• Some extra characteristics:
- New variants of the method based on fibre-reinforced composite materials could be proposed.
- New or extensive functionalities of BIPV units will be appreciated positively, such as: heat
collection and/or dissipation (BIPVT, Building Integrated Photovoltaic Thermal), energy passive
and/or reactive properties, structural functionality in the building, etc.
- The use of the same products like different construction unit, or in different architectural locations,
would increase the applicability of the product.
- Originality of design and aesthetical results could bring an added value to the catalogue.
- Easily scaling and standardizing would multiply the number and options of products for the
portfolio, making possible the customization of BIPV systems.
Architectural and photovoltaics analysis.
• Partners involved must to give their opinions and suggestions about the preliminary designs. In this
regard, architectural and photovoltaics analysis will be carry out about the following subjects:
- BIPV analysis of preliminary designs.
- Definition, standardization and extension of BIPV products.
- Material, constructive and electric characteristics.
- Manufacturing procedures and work conditions.
• Preliminary designs will be redesigned according with the architectural and photovoltaics analysis
within Task 2.3, with especial attention to those selected for demonstration.

ELABORATION GUIDELINE OF TECHNICAL TEMPLATES
Technical Templates.
• Every partners of the “Task 2.2” will create several “Technical Templates”. These templates will
correspond to every technical aspect of the products, and they will be also used forward: in “D2.3.
Specifications for every product selected” for the characterization of products, and in “Task 2.3.2” for
the detailed characterization and simulation of the BIPV selected for demonstration.
• The collection of these templates, once filled out them for every products of the portfolio, will constitute
the information package (“Product Folder”) needed to make up the catalogues and guidelines of WP6.
The collection of “Products Folder” will constitute the “Products Portfolio”.
• Denomination of Technical Templates:
- T1. General Description, Design and Materials of BIPV Products.
- T2. Mechanical Performance of BIPV Products.
- T3. Architectural Integration of BIPV Products.
- T4. Electrical Performance of BIPV Products.
- T5. Thermal Performance of BIPV Products.
- T6. Optical Performance of BIPV Products.
- T7. Acoustic Performance of BIPV Products.
- T8. Manufacturing processes of BIPV Products.
- T9. Estimation of PV Production of BIPV systems.
- T10. Simulation of Passive Performance of BIPV systems.
- T11. Economical Evaluation and Benefits of BIPV Products.
Guideline for the elaboration of Technical Templates.
• Every template must show the technical parameters or features useful for the total characterization of
the products and their integration in architectural environments.
• “Technical Templates” must be thought to satisfy the needs of characterization of every BIPV product
of the portfolio: ventilated façades, curtain walls, skylights, roofing shingle and shading systems. Then,
it is necessary that be complete and flexible.
• The Technical Templates might content: tables, pictures, graphics, etc. in the format suggested in this
“Generic Technical Template”.
• You can define several data levels to make up the tables:
- “UNIT” and “SUB-UNIT”: correspond to building or technological units/sub-units,
manufacturing/ installing procedures, economical/ financial calculations, etc.
- “Subject”: is a unit of minor order such as: matter, issue, aspect, etc.
- “Concept/s” and “Parameter/s”: regard descriptive and numerical characteristics. There are
three cells to introduce numerical values per parameter, this has been thought to be able to
introduce values such as: geometrical dimensions, unit/m2, unit/€, unit/year, etc.
• You can define several graphic units to make up the pictures:
- “TITLES” and “SUB-TITLES”: artistic sketches, design plans, exploded drawings, manufacturing/
installing procedure, simulation screens, graphic design images, etc.
• In the cell “Observation” any additional information can be included, such as legends, explanations,
testing and measuring reference conditions, data sources, copyrights, etc.
• Some additional requirements:
- Measure units of the parameters must be expressed in metric system, except for exceptions.
- Economical parameters must be expressed in Euros, without VAT or any tax.
- Every technical template will have its own structure and distribution, make up them freely.

4.1 Selection of products for BFIRST portfolio
A set of BIPV products were proposed by TECNALIA and ACCIONA in order to configure
the BFIRST portfolio of products.
Façades and roofs of buildings will be the architectural units where placing the BFIRST
products of the portfolio. None of them will have structural functionality; so that, they will be
considered as self-supporting construction elements from the point of view or architecture
with similar requirements of façade and roofing traditional units, besides the photovoltaics
ones. In the other hand, several functions might be assumed by the products within the
architectural spaces where will be set up:
- Façades: ventilated façade unit, curtain wall, shading system unit.
- Roofs: skylight unit, roofing shingle.
Some BFIRST products offer the possibility to be used for different functionalities depending
on the location, the anchoring system chosen to fix them at the building envelop and the
energy passive features of constructive solutions. This versatility makes possible to reduce
manufacturing costs and it makes easy the execution of the building integration, even
adapting the construction units right on the building site in order to customize the product for
the final function to carry out. The energy active and passive functionalities would reduce the
energy consumption and save money to the property. Standardization and aesthetical subjects
have been also taken into account to make up the portfolio of products. Functional,
standardization and aesthetical versatility will be the main criteria to create families of
products coming from the original ideas proposed.
Several manufacturing materials and procedures to implement the BFIRST products have
been considered. The only common requirement for the whole of products proposed is the
encapsulating method of the photovoltaics array within a fibre-reinforced composite matrix,
which will be developed and improved within the Task 3 of BFIRST project. Nevertheless,
depending on the specific characteristics of the product to manufacture, different possibilities
of apply this procedure will be considered. Overall in those cases in which other material
layers to procure any certain feature are involved. In the other hand, framing and anchoring
systems have a relevant importance for the designs of products and the placement at the
building envelop. In any cases, these subjects make the difference among the several
possibilities of uses and integration typologies of the products in building.
Taking into account all the subjects expressed above, it has been generated a set of 11 BIPV
products to include in the BFIRST portfolio covering the diversity of architectural spaces and
uses, 3 ventilated façades elements and 2 elements of the rest of construction units: curtain
wall, shading system unit, skylight unit and roofing shingle:

Short description
A façade cladding element with integrated PV technologies,
manufactured in composite materials and as the outer envelope of
a ventilated façade.
Design concept: curved panel with planar regions where the PV
cells would be placed.
The ventilated façade concept allows the hybridity of the panel to
be considered.
The curved transitions between planar regions provide with
additional rigidity from a mechanical viewpoint, as well as being
aesthetically attractive, given the possibilities that composites
offer in terms of design with respect to other more conventional
solutions (i.e. glass).

VF03. Translucent PV ventilated façade
Definition
Photovoltaics construction element for ventilated façades and skylights.
Picture
Short description
Photovoltaics module encapsulated with fibre-reinforced and
resin over single glass super-stratum.
External unit of the ventilated façade. Internal one would be a
double glass unit with insulating air chamber. The façade as a
whole would be fixed to the floor building structure by means
mechanical anchoring.
Dissipation of residual thermal energy would be carried out by
natural convection through the backside of the panels, to take
advantage of the differential atmospheric pressure between the
top and the bottom of the façade. Thermal dissipation would
improve the PV performance. The PV construction element could
be also located with similar passive energy use in the roof of the
building, having a complete envelop covering the building entire.

4.2 Selection of products for BFIRST demo
As said in the description of works of the Task 2.2, some of the BIPV products ideated by
ACCIONA and TECNALIA and analyzed by BEAR and ATERSA were proposed to be
tested in laboratory and real demo-site buildings located in 3 different countries of the
European Union.
This task was the main topic debated during the last General Assembly Meeting, celebrated in
Madrid on the 3rd and 4th of December 2013. The subjects regarding the detailed designs of
products for demonstration and the requirements of integration at the demos-site buildings are
still under discussion.
At the moment, 5 BIPV products have been selected for prototyping and testing, each one of
which will be set up in one of the 3 demo-site buildings of Spain, Greece and Belgium:
• Spanish demo-site:
- CW01. PV layer for curtain-walls.
- SL02. PV ventilated skylight.
• Greek demo-site:
- VF01. Non-planar ventilated façade module.
- SE02. Folding-screen shading system.
• Belgium demo-site:
- RS02. PV sawtooth roofing shingles.
Selected products for demonstration will be designed with a maximum detail throughout the
next task of WP2. Designs, materials and procedures are being conceived to achieve products
easily adaptable to the needs of the specific buildings, in projects of new construction and
retrofitting. BFIRST products will be able to be used in a wide range of circumstances in
building works. The customization of the designs proposed for demo in the framework of
BFIRST project will be a practice example of this advantage. In this regard, some aspects of
the detailed designs of prototypes will be conditioned to the characteristics of the constructive
environment of demo-site buildings.
In the next figure it is showed the last advances regarding the constructive considerations
about the building integration of selected products. Architectural and installations plans are
being examined to procure the correct integration of the developed elements within the new or
retrofitted buildings. The presence of planned or existing elements of construction is being
taken into account.

5. Elaboration of Technical Templates
“Technical Templates” are a set of index-cards useful for the complete characterization of
BFIRST products of the portfolio. Every technical aspect of the products will be showed in its
respective technical template.
They will be used during the execution of “D2.3. Specifications for every product selected”
and in “Task 2.3 Detailed designs of BIPV elements”, They will gather all the information
coming from the data sheets of commercial materials and devices used for the implementation
of the products, or generated by means of software simulations or direct testing in lab. They
will also content the guidelines for manufacturing, installing and operate the elements. As
well as environmental impacts; financial data regarding the products and their manufacturing,
integration and maintenance; and economic benefits foreseen for active power generation and
passive energy saves.
Once filled out, the collection of these templates regarding a product will form the product
folder, an information package needed to make up the catalogues and guidelines of WP6. The
set of products folder will constitute the portfolio of products, as explained in Section 3.3.
In order to carry out this task it has been generated a “Generic Technical Template”, attached
in Section 3.5, to make easy the subsequent creation of every technical template. Proposed
technical templates for the characterization of products are the following:
- T1. General Description, Design and Materials of BIPV Products: it will gather the
geometrical and material design and measures of the products including all their
components and occasionally, if necessary, additional pieces involved in the anchoring
or construction systems recommended as structural support. Together with the 2D and
3D plans of designs, a general description of the product will be also showed.
- T2. Mechanical Performance of BIPV Products: it will gather the mechanical and
dynamical behaviour of the elements. As said in Section 4.1, BFIRST products do not
make structural function from the point of view of architecture, but have to follow the
mechanical requirements of self-supporting construction units for façades or roofs
envelops. In any case, it might be possible to introduce details of management of hand
positioning or automatic solar tracking.
- T3. Architectural Integration of BIPV Products: it will gather all the information
needed to make an effective integration, within the architectural units of façade or
roof, from the functional and aesthetical points of view. Interaction with the rest of
construction elements will be taken into account for new buildings, and with the
existing elements for retrofitting projects. Details of setting up, maintenance and
removing procedures will be also explained.
- T4. Electrical Performance of BIPV Products: it will gather the whole of the electrical
data usually available in photovoltaics products data sheets, including those aimed to
calculated thermal losses and other parameters useful for the estimation of power

production. Other electrical devices used will be also described in this section, as
optimizers, connectors, cables, diodes, etc.
- T5. Thermal Performance of BIPV Products: it will gather all the thermal properties of
the elements as construction units for façade or roof envelops. Some of the designs has
material insulation layer to protect the building inside of the solar radiation and the
heat dissipated by the photovoltaic generator. Some others have vacuum chambers to
make similar functions. This subject will be essential to simulate the thermal
behaviour of the building in order to achieve a comfortable inside environment.
- T6. Optical Performance of BIPV Products: it will gather the optical features of units,
aimed overall to evaluate the element as an energy passive unit able to absorb, reflect
or let the light of sun to go through. The optical performance will be especially
interested for shadowing systems proposed. These subjects will be also important to
understand the aesthetical possibilities of the products, as much from outside as from
inside of the buildings.
- T7. Acoustic Performance of BIPV Products: it will gather that information relevant to
control the acoustic insulation of the building inside. The measures to avoid the impact
of noises will be taken in junction with thermal insulation as usually in fitting out of
building envelops.
- T8. Manufacturing Processes of BIPV Products: it will gather all the instructions and
requirements for manufacturing the BFIRST products with the purpose to make
possible the implementation of products in factory and make easy the manufacture
works of the prototypes for demo. All the elements proposed have in common the use
of a matrix in fibre-reinforced composite, but there will be variations regarding the
rest of components involved in the making up and assembly of final products.
- T9. Estimation of PV Production of BIPV systems: it will gather the estimation of the
photovoltaics production for generic cases of integration in a building model, at
different locations of Europe and under several work conditions. Software tools of
photovoltaics estimation will be used for this task. It will be also estimated the
generation in the BFIRST demo-site buildings, with the purpose to compare the results
with those coming from the demonstration tests.
- T10. Simulation of Passive Performance of BIPV systems: it will gather the results of
passive energy simulations for a building model at different location of Europe. The
simulation will consider heating and lighting effects over the building envelope and
the influence of these factors at the building in order to ensure the wanted insider
comfort conditions.

financial rates relative to the BFIRST products; such as manufacturing materials and
procedures, installation, maintenance and removing works, etc. This document will
also content data of economic benefits foreseen for active power generation and
passive energy saves.
