The exponential growth in world population necessitates 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 additionally 15 % energy is lost in distribution to the building. So it is necessary to save energy, efficiently usepower and also generate power at the site itself.

The term building-integrated photovoltaics (BIPV) refers to the concept of integrating photovoltaic elements into the building envelope, establishing a symbioticrelationship 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 installationof facilities and superstructures, which means that BIPV façades are of particular value in highdensity urban centres.

It is important to consider the potential cost benefits of off setting 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 % lightingenergy reduction, and also generates power from these areas.

Photovoltaic glass with crystalline silicon technology is madeup of an external layer of glass and an internal layer of glassor other TEDLAR materials, there being crystalline cellslaminated between both layers, according to the size of theglass. The power will be defined by the number of cells andtheir technology.

Thus, there are monocrystalline silicon cells (formed from asingle silicon crystal) and polycrystalline cells (formed bydifferent macrocrystals that are formed from differentcrystalline seeds in vertical growth ovens). These cells can inturn be either 6” or 5”.

Crystalline glass usually has power values of around 100 –170 Wp per square meter, depending on the technology, theseparation between the cells and efficiency of these cells.

In constructive solutions where electricity generation takesprecedence over aesthetic appearance, such as pergolas, brisesoleils or canopies, it is usual to choose crystalline silicontechnology.

Increase inBuilding Real Estate Value,Resale Value, Occupany Rate

In the real estate sector, energy performance may be a newasset valuation tool. This is being aided by mandatorycertification and disclosure policies in several large cities inthe United States, in Australia, and in Europe, along withvoluntary programs like ENERGY STAR and LEED,Australia’s Green Star and NABERS ratings, and EnergyPerformance Certificates (EPC) in Europe. The 2012 GRESBsurvey from the Global Real Estate SustainabilityBenchmark offers early evidence that performancecertification is an emerging trend in evaluating a real estateportfolio.

For a number of years, advocates of green buildings havestated that efficient, green buildings not only have lowerenergy bills, but their design and features improve theoccupants’ experience and worker productivity. And byextension, these green attributes should increase the value ofa building in the real estate market.

In the 2012 global Energy Efficiency indicator (EEI) surveyconducted by the Johnson Controls Institute for BuildingEfficiency, 44 percent of building executives (versus 35percent in 2011) said their organizations planned to pursuevoluntary green building certifications for existing buildingsin the next year. A good percentage of respondents said theyhad at least one certified green building. There, somebuildings are experiencing “brown discounts” for poor energyefficiency ratings.

Buildings with NABERS ratings of less than 3 starsreported significant discounts in value 10% in Sydney and13% in Canberra. (Newel 2011) These findings may haveglobal implications and may be indicative of the future ofthe real estate market where the value of buildings will bediscounted for low energy performance rating.

A report published by the RICS, concluded that a clear “linkis beginning to emerge between the market value of abuilding and its green features and related performance”(RICS, 2005, p.3). Studies done by Miller and Fuerst andMcAllister found that green buildings had a positive impacton rents and values. Though there were variances in theextent of the relationship, a positive effect of the Energy Starcertification was common among the three. They found thatthe average LEED impact on sales price per square foot is9.94%, while the Energy Star impact on sale price is 5.76%.

Energy Star certification achieved more than 3% rental persquare foot with increment selling prices as high as 16 percent. The results suggested a premium for Energy Starbuildings, but not LEED certified buildings . Fuerst andMcAllister (2007) analysed transaction prices for 292 EnergyStar and 30 LEED certified buildings. A 10% pricepremium was found for Energy Star and 31% price premiumfor LEED certified buildings as compared to non-certifiedbuildings within the vicinity.

In Singapore, Deng analysed the economic returns ofenergyefficient investments in the local housing market. Thestudy looked at 62,434 transactions of Green Mark certifiedand noncertified residential units, using a 2-stage design inits empirical analysis. The research concluded that theGreen Mark price premium commanded about a 6%premium over comparable noncertified dwellings, withhigher premiums for higher certifications, i.e. up to 14%premium for a Green Mark Platinum certification.

* Increased resale value (2-17%)

* Increased rental rates (5.8-35%)

* Higher 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%)

The expression GREEN building and SUSTAINABLEbuilding are often used interchangeably, though these termscan have different meanings too.

Green buildings can be expected to consume less energyand thus consequently generate lower CO2 emissions.The definition of a Sustainable building, according toLutzkendorf and Lorenz (2007, p.60), “goes far beyond thenarrower concept of lowering a building’s energyconsumption”, as sustainable buildings are constructedwith a higher urban planning, creative, functional andtechnical quality.

However, in this context ‘green building’ has been used andcan be defined as those which have low environmentalimpact throughout the various phases of a buildings’ lifecycle, that is; in their design, construction and operation anda building that offers health and well being for occupantsEnvironmental characteristics generally include resourceefficiency (water, energy), design and use of materials andresources, indoor environmental quality and innovation etc.

Social factors would look at health and safety, includingcompliance with legislation, occupant satisfaction andproductivity. A balance of economic, social performancetogether with environmental protection factors should beevaluated assessment of built assets.

In addition to environmental benefits it also places a strongfocus on health and productivity. Some of the commonattributes found to promote healthier working environmentsinclude improved comfort and better ventilation,significantly better lighting quality; i.e. more day lightingand greater occupancy control over light levels, much lowersource 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 morecomfortable buildings on the value of property wouldbe difficult. Incorporating green design into anorganisation’s building may also improve its image andvisibility and thus generate intangible benefits.

According to Wasiluk (2007), sustainable commercialbuildings have a competitive advantage overconventional buildings and are able to attract higherprofile tenants, command above market rentals andthus increase capital values. These findings have beensupported by Miller et al. (2008), who conclude that EnergyStar and LEED certified office buildings in the UShave a competitive advantage over their nonratedcounterparts.

Quatifying the Benefits Some links are beginning to emergebetween market value of a building, its sustainable featuresand financial performance. This was based on case studiesin Australia that identify the economic value of certificationof sustainable buildings. The Green Building Council ofAustralia (2008) reported that sustainable buildings inAustralia commanded 5% to 10% higher rents and hadhigher 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 awardand energy consumption figures (before and after retrofit)and capital expenditure for the retrofit project. The studyconcluded that retrofitting can lead to an increase in theproperty value of about 2%, with an average expectedsavings in operating expenses of 10%.

Through extensive research, market studies andindustry reports in this area, it can be said thatthere is a general consensus that sustainablebuildings: -* 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

Studies have clearly demonstrated the nonenergy relatedbenefits of daylighting, in addition to energy savings.

The Wavelengths of Lights and the effects of Day Light onthe body has impact on building occupants psychologicallyand physiologically. Different wavelengths or spectraldistributions of light have different effects on the humanbody.

Most electrical light sources lack the spectral distributionneeded for complete biological functions, although fullspectrum fluorescent lighting does come close to that ofnatural light. Cool white f luorescent lights, Incandescentlamps, energy-efficient fluorescent lighting (Except LED)lack the blue portion of the color spectrum, which is the mostimportant part for humans and is best provided by naturallight.

The majority of humans prefer a daylit environment becausesunlight consists of a balanced spectrum of color, with itsenergy peaking slightly in the bluegreen area of the visiblespectrum, natural light also has the highest levels of lightneeded for biological functions.

The photobiologic action spectra of greatest importance tohumans ranges from 290 to 770 nanometers. Skin reddeningand vitamin D synthesis occurs in the range of 290 to 315nanometers. Tanning or pigmentation of the skin andreduction of dental occurs in response to band light in theband from280 to 400 nanometers.

Vision is the most sensitive to light in the 500- to 650-nanometer range (yellowgreen light). Billirubin degradationoccurs in response to light in the 400- to 500-nanometerrange (blue light). The human eye functions at its best whenit 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 thesource, which leads to improper functioning of the eye.

Therefore, the superior spectral content of natural lightmakes it the best light for the eye Both the central nervoussystem and the neuroendocrine hormonal system are influenced by the powerful stimulus of light - claimed thatlight has biological effects important to health and thatsome of these effects could be measured in a laboratory. Theeffects of light fall into two categories: those modifyingindividual endocrine, hormone, and metabolic state by lightreaching the retina and those resulting from light on theskin. Some effects of light on the skin are vitamin Dproduction, skin tanning, and dissociation of bilirubin.

Other studies have also supported the possibility ofphysiological benefits from light. Light falling on the retinaand being transmitted to the hypothalamus controls ourcircadian rhythms, which are responsible for synchronizingour internal clock to 24 hours. The effects of light oncircadian rhythms can be studied using physiologicalvariables such as the daily patterns of core body temperature,levels of melatonin, urine production, cortex activity, andalertness.

Occupants in daylit and full-spectrum office buildingsreported an increase in general well being. Specific benefitsin these types of office environments include better health,reduced absenteeism, increased productivity, financialsavings, and preference of workers. Benefits to the officeworker are so great that many countries in Europe requirethat workers be within 27 feet of a window.

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 on the psychological and

physiological aspects the occupants of the building.

The comforting space and connect to the environment

provide benefits to occupants as significantly as the

energy savings to building owners and managers.

Benefits of Natural Lightingand

Hazards of Artificial Lighting

Architecture is a design process which involves planning,designing, creating, erecting, constructing and executingconstruction of various types of buildings that arefunctionally efficient, economically viable andaesthetically pleasing.

The two most important factors in the design of abuilding are Form and Function. Functionality is themost important aspect of building design. The other aspectis building form or aesthetics.

Aesthetics is the branch of philosophy that deals with thenature and expression of beauty.

Aesthetics is one of the major principle of Architecturethat students and professionals alike have to worship. Itconcerns beauty or appreciation of beauty. In other words,it is a philosophy behind a pleasing appearance. A set ofprinciples followed by the Architectural designers or anydesigners for that matter for the evolution of the endproduct that is aesthetically pleasing to the eye, is calledaesthetics. It is directly influenced by the artistic taste ofan individual.

When a building is designed, the aesthetic aspects can besatisfied using elements such as sloped roof, decorativecolumns, roofs for window elements, and semicircularand segmental arches. Color is an element of our visualperception 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 constructa building. These color choices can be quite subtle, such asusing a warm, yellow toned concrete instead of a cold graybase, or using a brownish brick instead of the traditional red.

However, the architect must consider the color effect of everyelement of a building’s construction, from the earthy colors ofprimary construction materials like wood, stone, brick andmarble, to the expansive variety of colors available for paint,doors, windows, siding, and trim.

Light and dark are relative perceptions of light. Architects usethe concept of light and dark as they create visual interest ona 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, andbroad, f lat 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 adark space wrapping around a building.

Space is the relative position of one three-dimensional object toanother. Space is one of the most important considerations anarchitect must think about while designing a building,because the sizes of rooms and hallways, the height of ceilingsand the ease of entering and exiting each living area mustcarefully match the function of the building.

Architects chose dimensions of rooms to match the number ofpeople who will occupy the space and the amount of activitythat will occur in it. To make a building more interesting,

architects will experiment with aesthetic qualities of space byvarying the width and height of rooms through which peoplewill move. Architects also speak of space as the amount ofland that will be occupied by a building on a site. Theremaining area is called open space.

In much of contemporary architecture, the notion of expressiveexteriors becomes tempered by new materials such as: highperforming glass that conveys literal openness in an age ofdigital communication via the Internet or alternative roofingtechnologies that can extend the livable areas to the top ofbuildings proving a green space that can hold storm waterand offer new amenities.

Onyx Solar have developed a unique constructionmaterial that combines active and passive properties ina single element. This is why the main characteristic thatdefines ONYX Solar’s photovoltaic glass itsMULTIFUNCTIONALITY. There is no direct exclusivecorrelation between a type of glass and an integration, sincethis depends on many factors.

Onyx Solar photovoltaic glass behaves like any other glassused in construction. The big difference is the ability togenerate power. Have a wide range of glass formats,sizes, thicknesses suitable for every need, depending onthe impact resistance values or any other values that arenecesary in order to comply with local regulations, theproject’s technical requirements, etc.

ColourIn line with the customisation criteria that make ONYXunique and through the use of colored PVB sheets, OnyxSolar is able to offer a full range of color options that willvary depending on the transparency degree. It is a productpatented by Onyx Solar and This range of colors does notprevent the glass from maintaining its photovoltaic orluminous properties, which is a clear example of OnyxSolar’s multi-functionality.

The BIPV constructive solutions recommended for theincorporation of color into the glass are skylights andcurtain walls, since the color goes onto the inner player ofthe glass and will be seen in their exact tone from theinside. However, the tone will be much darker from theoutside of the building due to the natural color of theamorphous silicon.

Amorphous Silicon (Thin Film) The Thin Film oramorphous silicon technology which is formed by depositingdifferent kinds of treated silicon onto a glass substratum,followed by laser etching to establish the edges of the cells(and, if applicable, of the transparency). In constructivesolutions where the aesthetic appearance and thetransparency and/or homogeneity of the glass takeprecedence, such as curtain wall or skylight, it is usual toselect amorphous silicon technology.

TransparencyOne of the most important characteristics of Onyx Solar’sphotovoltaic glass is its range of transparencies. Itmanufactures photovoltaic glass that enables the passage ofnatural light into the interior of buildings and does notreduce indoor habitability.

Onyx Solar recommends different transparency degreesdepending on the climate and geographical conditions of thefacility, as well as the location and tilt of the photovoltaicglass in the building.

In glass with amorphous silicon technology, transparency isachieved through the removal of amorphous silicon layersusing a laser etching process, in other words, part of thesilicon deposit is removed through a controlled process,thereby gaining a degree of semi-transparency.

Logically, when transparent gaps are made in the glassremoving some of the active photovoltaic layers, thegeneration is reduced in proportion to the degree of semi-transparency achieved, therefore, a compromise must befound between the desired passive properties and expectedactive properties.

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

Amorphous Silicon Thin Film

Child Care Centre

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 exterior are lit low.

* Useful for Restaurent, Show rooms etc....
