is consumed by buildings
- for cooling, lighting,
pumps, motors, chillers
& other basic functions
More than a Billion Sq Mtrs are being built every
year in India.... which will start consuming power !!
5. Aesthetics Building-Value Compliance Comfort Incentives Save Energy
Okay, but, WHY BIPV !!
The exponential growth in world pop-
ulation over the coming years will call
into question the current energy model,
based on finite sources of fuel. It ne-
cessitates to create a NEW MODEL OF
CLEAN ENERGY and a sensible use of
alternate RENEWABLE ENERGIES.
Buildings alone consume over 40 %
of power generated, and adding 15
% energy lost in distribution to the
building.
So it is necessary to use measures which
will allow buildings to save energy,
efficient use of power, and generate
power at the site itself.
The term building-integrated
photovoltaics (BIPV) refer to the
concept of integrating photovoltaic
elements into the building envelope,
establishing a symbiotic relationship
between the architectural design,
structural and multi functional
properties of the building materials and
renewable micro energy generation.
The ratio of façade surface area to
roof surface area increases along with
the building height. In addition, the
available roof area is often reduced
due to the installation of facilities and
superstructures, which means that
BIPV façades are of particular value in
highdensity urban centres.
Most BIPV products reduce installation
costs by eliminating common PV
mounting hardware such as struts,
z-channels, and clips and associated
labor costs. BIPV modules may also
install more quickly than incumbent PV
modules. Additionally, it is important
to consider the potential cost benefits of
offsetting the use of traditional building
materials (e.g., asphalt shingles) in the
areas where BIPV is installed.
Also BIPV installations in the Curtain
Wall, Facade, Skylights and other Vision
Light Transmission (VLT) areas, offers
30 to 40 % heat reduction, approx. 10
% lighting energy reduction, and also
generate power from these areas.
• explosive growth of high-rise buildings
• more than a Billion Sq Mtrs are being constructed every year
in India alone. And all these buildings will start consuming
power - which is already deficient in most of the Indian States
• 40 % of generated power consumed by buildings
• bring down the energy needed by buildings
• can also think about NET-ZERO buildings
• no compromise on user comfort
• more KW per acre (no need for space between panels)
• every Rooftop, Skylight, Canopy, Pergola, Braise Soleil,

‘Green’ and ‘Sustainable’ Building
Through extensive research, market studies and industry
reports in this area, it can be said that there is a general
consensus that sustainable buildings: -
• are more energy efficient
• have lower operating and maintenance costs
• provides better comfort and well-being for occupants
• are more marketable than conventional buildings
• have lower risk potential
• reduced negative impact on the environment
The expression GREEN building and
SUSTAINABLE building are often
used interchangeably, though these
terms can have different meanings too.
Green buildings can be expected
to consume less energy and thus
consequently generate lower CO2
emissions.
The definition of a Sustainable
building, according to Lutzkendorf and
Lorenz (2007, p.60), “goes far beyond
the narrower concept of lowering a
building’s energy consumption”, as
sustainable buildings are constructed
with a higher urban planning, creative,
functional and technical quality.
However,inthiscontext‘greenbuilding’
has been used and can be defined as
those which have low environmental
impact throughout the various phases
of a buildings’ life cycle, that is; in their
design, construction and operation and
a building that offers health and well
being for occupants
Environmental characteristics
generally include resource efficiency
(water, energy), design and use of
materials and resources, indoor
environmental quality and innovation
etc. Social factors would look at health
and safety, including compliance with
legislation, occupant satisfaction and
productivity. A balance of economic,
social performance together with
environmental protection factors
should be evaluated assessment of built
assets.
In addition to environmental benefits
it also places a strong focus on
health and productivity. Some of the
common attributes found to promote
healthier working environments
include improved comfort and better
ventilation, significantly better lighting
quality; i.e. more day lighting and
greater occupancy control over light
levels, much lower source emissions
from building material etc. However it
also understood that the relationship
between worker comfort, productivity
and building design is complicated.
Measuring the financial impact of
greener more comfortable buildings on
the value of property would be difficult.
Incorporating green design into an
organisation’s building may also
improve its image and visibility and
thus generate intangible benefits.
According to Wasiluk (2007),
sustainable commercial buildings
have a competitive advantage over
conventional buildings and are able to
attract higher profile tenants, command
above market rentals and thus increase
capital values. These findings have been
supported by Miller et al. (2008), who
conclude that Energy Star and LEED
certified office buildings in the US have
a competitive advantage over their non-
rated counterparts.
Quatifying the Benefits
Some links are beginning to emerge
between market value of a building, its
sustainable features and financial
performance. This was based on case
studies in Australia that identify
the economic value of certification
of sustainable buildings. The Green
Building Council of Australia (2008)
reported that sustainable buildings
in Australia commanded 5% to 10%
higher rents and had higher relative
investment return and asset values of
10%.
Key factors considered included the
tenure, age of property, location, size,
Green Mark award rating and year of
award and energy consumption figures
(before and after retrofit) and capital
expenditure for the retrofit project. The
study concluded that retrofitting can
lead to an increase in the property value
of about 2%, with an average expected
savings in operating expenses of 10%.

increase in building-value
In the real estate sector, energy
performance may be a new asset
valuation tool.
This is being aided by mandatory
certification and disclosure policies in
several large cities in the United States,
in Australia, and in Europe, along with
voluntary programs like ENERGY
STAR and LEED, Australia’s Green
Star and NABERS ratings, and Energy
Performance Certificates (EPC) in
Europe. The 2012 GRESB survey from
the Global Real Estate Sustainability
Benchmark offers early evidence
that performance certification is an
emerging trend in evaluating a real
estate portfolio.
For a number of years, advocates
of green buildings have stated that
efficient, green buildings not only have
lower energy bills, but their design
and features improve the occupants’
experience and worker productivity.
And by extension, these green attributes
should increase the value of a building
in the real estate market. Recent
empirical studies are demonstrating
just that – energy efficient commercial
buildings and commercial buildings
with green attributes have:
• Increased resale value (2-17%)
• Increased rental rates (5.8-35%)
• H igher occupancy rates (0.9-18%)
• Lower operating expenses (30%)
• Higher net operating income
(5.9%)
• Lower capitalization rates (50-55
basis points)
• Productivity gains (4.8%)
Interest in green buildings continues
to grow. In the 2012 global Energy
Efficiency indicator (EEI) survey
conducted by the Johnson Controls
Institute for Building Efficiency,
44 percent of building executives
(versus 35 percent in 2011) said their
organizations planned to pursue
voluntary green building certifications
for existing buildings in the next year.
Sixty percent of respondents said they
had at least one certified green building.
There, some buildings are experiencing
“brown discounts” for poor energy
efficiency ratings. Buildings with
NABERS ratings of less than 3 stars
reported significant discounts in value
10% in Sydney and 13% in Canberra.
(Newel 2011) These findings may
have global implications and may be
indicative of the future of the real estate
market where the value of buildings
will be discounted for low energy
performance rating.
A report published by the RICS,
concluded that a clear “link is beginning
to emerge between the market value of
a building and its green features and
related performance” (RICS, 2005, p.3).
Studies done by Miller and Fuerst and
McAllister found that green buildings
had a positive impact on rents and
values.
Though there were variances in the
extent of the relationship, a positive
effect of the Energy Star certification
was common among the three. They
found that the average LEED impact
on sales price per square foot is 9.94%,
while the Energy Star impact on sale
price is 5.76%.
Energy Star certification achieved more
than 3% rental per square foot with
increment selling prices as high as 16
per cent.
The results suggested a premium
for Energy Star buildings, but not
LEED certified buildings. Fuerst and
McAllister (2007) analysed transaction
prices for 292 Energy Star and 30
LEED certified buildings. A 10% price
premium was found for Energy Star and
31% price premium for LEED certified
buildings as compared to non-certified
buildings within the vicinity.
In Singapore, Deng analysed the
economic returns of energy-efficient
investments in the local housing
market. The study looked at 62,434
transactions of Green Mark certified
and noncertified residential units,
using a 2-stage design in its empirical
analysis.
The research concluded that the Green
Mark price premium commanded
about a 6% premium over comparable
non-certified dwellings, with higher
premiums for higher certifications, i.e.
up to 14% premium for a Green Mark
Platinum certification.

Many building owners and architects have reported energy
savings received from daylighting. Looking at the energy
consumption of commercial buildings in the United States
demonstrates the importance of saving energy. According to
the Department of Energy’s Office of Building Technology, State
and Community Programs (BTS) 2000 Databook, commercial
buildings consumed 32% of United States electricity in 1998,
of which 33% went to lighting. Not only is electrical lighting
responsible for a significant amount of the electrical load on
a commercial building, but it can also cause excessive cooling
loads. Utility costs for a building can be decreased when
daylighting is properly designed to replace electrical lighting.

ONYX BIPV offers Natural Lighting & Daylighting
Along with the importance of
energy, studies have demonstrated
the nonenergy related benefits of
daylighting.
The Wavelengths of Lights and The
Affects of Light on the Body the impact
daylight has on building occupants.
Each building section includes the effect
daylight has on the building occupants
psychologically and physiologically.
Economic data have been cited in the
categories in which information was
found.
Before the 1940s, daylight was the
primary light source in buildings;
artificial lights supplemented the
natural light.
Now, Daylighting is often integrated
into a building as an architectural
statement and for energy savings.
However, benefits from daylighting
extend beyond architecture and energy.
The psychological and physiological
aspects of natural light should also
be considered. The comforting space
and connection to the environment
provided to occupants provide benefits
as significant as the energy savings to
building owners and managers.
Different wavelengths or spectral
distributions of light have different
effects on the human body.
Most electrical light sources lack
the spectral distribution needed for
complete biological functions, although
full-spectrum fluorescent lighting does
come close to that of natural light. Cool
white fluorescent lights, Incandescent
lamps, energy-efficient fluorescent
lighting (Except LED) lack the blue
portion of the color spectrum, which
is the most important part for humans
and is best provided by natural light.
The majority of humans prefer a daylit
environment because sunlight consists
of a balanced spectrum of color, with
its energy peaking slightly in the blue-
green area of the visible spectrum,
natural light also has the highest levels
of light needed for biological functions:
The photobiologic action spectra of
greatest importance to humans ranges
from 290 to 770 nanometers. Skin
reddening and vitamin D synthesis
occurs in the range of 290 to 315
nanometers. Tanning or pigmentation
of the skin and reduction of dental
occurs in response to band light in
the band from280 to 400 nanometers.
Visionisthemostsensitivetolightinthe
500- to 650- nanometer range (yellow-
green light). Billirubin degradation
occurs in response to light in the 400-
to 500-nanometer range (blue light).
The human eye functions at its best
when it receives the full-spectrum
of light provided by daylight. Many
fluorescent lights are concentrated
in the yellow-green portion of the
spectrum to obtain the most lumens
per watt; this unbalanced, narrow
spectrum limits the blue in the source,
which leads to improper functioning of
the eye. Therefore, the superior spectral
content of natural light makes it the
best light for the eye
Both the central nervous system and the
neuroendocrine hormonal system are
influenced by the powerful stimulus of
light - claimed that light has biological
effects important to health and that
some of these effects could be measured
in a laboratory. The effects of light fall
into two categories: those modifying
individual endocrine, hormone, and
metabolic state by light reaching the
retina and those resulting from light
on the skin. Some effects of light on
the skin are vitamin D production, skin
tanning, and dissociation of bilirubin.
Other studies have also supported the
possibility of physiological benefits
from light.
Light falling on the retina and being
transmitted to the hypothalamus
controls our circadian rhythms, which
are responsible for synchronizing our
internal clock to 24 hours. The effects
of light on circadian rhythms can be
studied using physiological variables
such as the daily patterns of core body
temperature, levels of melatonin,
urine production, cortex activity, and
alertness.
Occupants in daylit and full-spectrum
office buildings reported an increase
in general well being. Specific benefits
in these types of office environments
include better health, reduced
absenteeism, increased productivity,
financial savings, and preference of
workers. Benefits to the office worker
are so great that many countries in
Europe require that workers be within
27 feet of a window.

Aesthetics - art of beautifying the buildings
Architecture is a design process which
involves planning, designing, creating,
erecting, constructing and executing
construction of various types of
buildings that are functionally efficient,
economically viable and aesthetically
pleasing.
The two most important factors in
the design of a building are Form and
Function. Functionality is the most
important aspect of building design.
The other aspect is building form or
aesthetics.
Aesthetics is the branch of philosophy
that deals with the nature and
expression of beauty.
Aesthetics is one of the major principle
of Architecture that students and
professionals alike have to worship.
It concerns beauty or appreciation of
beauty. In other words, it is a philosophy
behind a pleasing appearance.
A set of principles followed by the
Architecturaldesignersoranydesigners
for that matter for the evolution of
the end product that is aesthetically
pleasing to the eye, is called aesthetics.
It is directly influenced by the artistic
taste of an individual.
Aesthetics is concerned with bringing
art into the daily lives of the people. Like
people need colorful, designer clothes
to wear and taste and presentation of
food. Likewise, people like to live and
work in places that are beautifully
designed and are aesthetically pleasing
to the eye.
When a building is designed, the
aesthetic aspects can be satisfied using
elements such as sloped roof, decorative
columns, roofs for window elements,
and semicircular and segmental arches.
Color is an element of our visual
perception that is related to how our
eyes perceive light. We differentiate
these perceptions and name them red,
blue, yellow, etc.
Architects use color in the choice of
materials used to construct a building.
These color choices can be quite subtle,
such as using a warm, yellow toned
concrete instead of a cold gray base, or
using a brownish brick instead of the
traditional red.
However, the architect must consider
the color effect of every element of
a building’s construction, from the
earthy colors of primary construction
materials like wood, stone, brick
and marble, to the expansive variety
of colors available for paint, doors,
windows, siding, and trim.
Light and dark are relative perceptions
of light. Architects use the concept
of light and dark as they create visual
interest on a building by choosing
shapes that create a sensation of depth.
When some shapes stick out, they leave
others in shadow. Narrow openings
often appear dark, as in a tunnel, and
broad, flat spaces look light.
Materials can be used to vary the light
quality of a building. For instance,
a band of tinted windows gives the
illusion of a dark space wrapping
around a building.
Space is the relative position of one
three-dimensional object to another.
Space is one of the most important
considerations an architect must think
about while designing a building,
because the sizes of rooms and
hallways, the height of ceilings and the
ease of entering and exiting each living
area must carefully match the function
of the building.
Architects chose dimensions of rooms
to match the number of people who
will occupy the space and the amount
of activity that will occur in it. To make
a building more interesting, architects
will experiment with aesthetic qualities
of space by varying the width and
height of rooms through which people
will move. Architects also speak of
space as the amount of land that will
be occupied by a building on a site. The
remaining area is called open space.
In much of contemporary architecture,
the notion of expressive exteriors
becomes tempered by new materials
such as: high performing glass that
conveys literal openness in an age of
digital communication via the Internet
or alternative roofing technologies that
can extend the livable areas to the top
of buildings proving a green space that
can hold storm water and offer new
amenities.

The appearance of the amorphous
silicon glass is different from the
exterior and the interior side of the
PV glass.
Viewed from the distance the
exterior side is similar to the
TINTED GLASS, whereas from the
interior, the views outside are clear
& unobstructed, which ever side is
brighter will be more visible from
the opposite side.
Taking an example of an Office building
with an A-Si curtain-wall :
• you will have a clearer view of the
outside from the office during the
daytime, when the light is more on
the exteriors than the interior
whereas,
• during the night time, the opposite
is true when the office spaces are lit
in the evening / night and the exte-
rior are lit low.

Onyx Solar have developed a unique
construction material that combines
active and passive properties in a
single element. This is why the main
characteristic that defines ONYX
Solar’s photovoltaic glass its MULTI-
FUNCTIONALITY.
There is no direct exclusive correlation
between a type of glass and an
integration, since this depends on many
factors.
Onyx Solar photovoltaic glass
behaves like any other glass used in
construction. The big difference is the
ability to generate power.
Have a wide range of glass formats,
sizes, thicknesses suitable for every
need, depending on the impact
resistance values or any other values
that are necesary in order to comply
with local regulations, the project’s
technical requirements, etc.
In line with the customisation criteria
that make ONYX unique and through
the use of colored PVB sheets,
Onyx Solar is able to offer a full range of
color options that will vary depending
on the transparency degree.
It is a product patented by Onyx Solar
and This range of colors does not
prevent the glass from maintaining its
photovoltaic or luminous properties,
which is a clear example of Onyx Solar’s
multi-functionality.
The BIPV constructive solutions
recommended for the incorporation
of color into the glass are skylights and
curtain walls, since the color goes onto
the inner player of the glass and will be
seen in their exact tone from the inside.
However, the tone will be much darker
from the outside of the building due
to the natural color of the amorphous
silicon.
Amorphous Silicon (Thin Film)
The Thin Film or amorphous silicon
technology which is formed by
depositing different kinds of treated
siliconontoaglasssubstratum,followed
by laser etching to establish the edges
of the cells (and, if applicable, of the
transparency). In constructive solutions
where the aesthetic appearance and
the transparency and/or homogeneity
of the glass take precedence, such as
curtain wall or skylight, it is usual to
select amorphous silicon technology.
Advantages of A-Si (Thin Film)
• Greater Energy production (kWh)
at the same installed power (kWp)
• Low Temperature Coefficient. The
yield of A-Si PV glass module is
better under Higher Temperature
than with Crystalline PV Modules.
(In Singapore, a 10 kWp - a
Crystalline Module glass gives
around 11,000 to 12,000 kWh only,
whereas A-Si Module gives 12,400
to 14,000 kWh, with the same 10
kWp System - at around 40 deg C)
• Better behavious in the presence of
SHADOWS
• Less Dependance on TILTS
• Enable a more AESTHETIC
Integration
• Shorter amortization period
Transparency
Oneofthemostimportantcharacteristics
of Onyx Solar’s photovoltaic glass is its
rangeoftransparencies.Itmanufactures
photovoltaic glass that enables the
passage of natural light into the interior
of buildings and does not reduce indoor
habitability.
Onyx Solar recommends different
transparency degrees depending on the
climate and geographical conditions
of the facility, as well as the location
and tilt of the photovoltaic glass in the
building.
In glass with amorphous silicon
technology, transparency is achieved
through the removal of amorphous
silicon layers using a laser etching
process, in other words, part of the
silicon deposit is removed through a
controlled process, thereby gaining a
degree of semi-transparency.
Logically, when transparent gaps are
made in the glass removing some
of the active photovoltaic layers, the
generation is reduced in proportion
to the degree of semi-transparency
achieved, therefore, a compromise
must be found between the desired
passive properties and expected active
properties.

Photovoltaic glass with crystalline
silicon technology is made up of an
external layer of glass and an internal
layer of glass or other TEDLAR
materials, there being crystalline
cells laminated between both layers,
according to the size of the glass. The
power will be defined by the number of
cells and their technology.
Thus, there are monocrystalline silicon
cells (formed from a single silicon
crystal) and polycrystalline cells
(formed by different macrocrystals that
are formed from different crystalline
seeds in vertical growth ovens). These
cells can in turn be either 6” or 5”.
Crystalline glass usually has power
values of around 100 – 170 Wp per
square meter, depending on the
technology, the separation between the
cells and efficiency of these cells.
In constructive solutions where
electricity generation takes precedence
over aesthetic appearance, such as
pergolas, brise soleils or canopies, it
is usual to choose crystalline silicon
technology.
Advantages of Crystalline Cell based
BIPV :
• Applicable to Rooftop, Canopy,
Power Farms & Spandral Areas
• Greater Nominal Power per sq mtrs
• Lesser installation area required
for equal power (compared to thin
film)
• Greater Efficiency - 15 to 17 %
• Easier Installation - electrically &
structurally
• Proven Technology
• Easier to Maintain & Service
• Wide range of Size & Power range
• Easily available with vendors
• more than 90 % market share
world-wide
With regard to crystalline silicon based
technology, the colors can be from
the encapsulation (in a similar way to
amorphous silicon) combined with
transparency; playing with opaque
color backgrounds through tedlar or
ceramic frits or using colored cells with
the consequent of loss of efficiency,
depending on the colour.
