PROJECT GOALS

Evaluate the existing lighting system of the room to check FIUNmeets the average levels established by the technical regulation ofpublic lighting (RETILAP) in ColombiaCheck the parameters that inefficient and dysfunctional thesystem in the room FIUNAnalyze possible alternatives to improve the lighting system.Include a lighting system with intelligent control and add thesunlight as the key to energy saving. Develop a comprehensive proposal to implement a moreefficient system and lower energy consumption with the same or

better levels of illumination.

Submit a proposal with a budget and control chart tocomplement the lighting design.

WORK PROPOSAL

A preliminary design is performed FIUN room, with thecurrent lighting system, for which an energy analysis isperformed, and lighting.

The possibility of a change in the architecture, and thelighting system including alternatives to improveenergy consumption while improving levels of lux inthe room FIUN is then evaluated.

Finally, an emergency lighting system will beproposed, and lighting control system considering thedaylight factor and automated control system.

PROBLEMS ENCOUNTERED IN CURRENT SYSTEM

Ceiling uneven: The current ceiling is irregular and therefore some

luminaires are installed incorrectly and thus its light doesnot fail properly

Limitations on maintenance The false ceiling complicates lighting maintenance

Dark areas and damaged lights Control complicated lighting and misplaced

Energy spent lighting up the sky Ecological damage to birds and insects

Limited use of natural lighting to enhance interior lighting Control bad location and poor lighting.

ROOM FOR IMPROVEMENT FIUN

It is implemented in the architectural environment with the roomat floor level parallel uniform and false ceiling.Modification of the control elements is done, which should beindependent columnsThe idea of using a single technology T5 and / or LED luminaires

2x32 to 1'x4 'for the main lighting (the Cooper Lighting technologyis used, and General Electric that is already in the country) isproposed.Given that the room is FIUN class meetings and special lightingfor the board, create an environment that allows and keep othersoff the lighting used for presentations. The day use natural light to save energy is proposed, twosections of lights off.

Lighting calculations are performed with the chosen proposaland below.

ANALYSIS MAIN LIGHTING

Alternative 1 meets 500 lx levels and averaged 0.627 anduniformity UGR 21. Its energy efficiency is 9.62 W / m2With 10luminaires.Alternative 2 provides search results to levels of 500 lx onaverage and uniformity of 0.708 and UGR 20. Its energy efficiency

is 8.41 W / m2

With 10 luminaires.Alternative 3 also meets the standards of 500 lx and averaged0.692 and uniformity UGR 20. Its energy efficiency is 10.31 W / m2With 12 lights, why not improve the situation of Alternative 2.Alternative 4 does not meet the levels of 500 lx and averaged0.692 and uniformity UGR 21. Its energy efficiency is 6.21 W / m2With 10 lights, however it can not be used in this type of enclosure.Considering the above results, by power consumption andresults using the alternative two (GE 48 W LED 1'x4 ') .

SYSTEM ANALYSIS AT DAYLIGHT


27/37

SYSTEM ANALYSIS AT DAYLIGHT

Two control groups are conducted to verify the use of daylight tokeep some lights turned off, allowing the light to be used on

maintaining light levels and save energy. In this case the controlgroup which is located off of the top, and is located on the bottom ..

SYSTEM RESULTS IN DAYLIGHT

29/37


Considering the alternative chosen GE 48 W LED 1'x4 ' andenergy efficiency of 8.41 W / m2 With 10 lights and 500 lx on

average can be obtained with day light, an energy efficiency value4.08 W / m2, With 5 lights in operation, and five luminaires off tothe day, with an average illuminance of 695 lx, which representsthe evolution in savings of up to 50% of energy consumption.

You can turn an additional fixture near the board, with this value of692 lx on average is obtained, however, by turning off all otherlights, there is a considerable decrease in luminous flux reachingthe opposite side where it is the window, it is not recommended toturn them off in the day.It is also considering the use of a curtain or attenuation system that

prevents sunny days in the glare of the students in the room FIUN.

EMERGENCY LIGHT


30/37

EMERGENCY LIGHT

Being a hall of small dimensions, but with a defined circulationarea, it is proposed to use a self-contained emergency luminaire,

and supplementing with LED bulbs, which have lower energyconsumption, which means longer operating in an emergency.

EMERGENCY LIGHT


31/37

EMERGENCY LIGHT

Emergency lighting values of 5 lx,

sufficient for effective evacuation of

students who are in an emergencyroom in FIUN are obtained.

CONTROL SCHEME


32/37

CONTROL SCHEME

The control system consists of three circuits 2, one general lighting and emergencylighting. In the latter automatic battery charger within the luminaire 3 fordownloading system used. Initially control is manual with a dual switch switchable.

CONTROL SCHEME


33/37

CONTROL SCHEME

SE adds a custom control scheme for classrooms, which is ele AP ClassroomSolution Cooper Controls, which allows attenuation or dimerization to the requiredsettings, using an occupancy sensor, daylight sensor, and two controls manuals,

one for input and one with predefined settings, for board and work area located nextto the board, which can be easily checked by the teacher.

EMERGENCY LIGHTING CONTROL SCHEME


34/37

EMERGENCY LIGHTING CONTROL SCHEME

At the proposed control system can add a module called Cooper CEPC EmergencyPower Control Sample One-LineWhich allows use some normal lighting circuits, asystem of emergency lighting, or also use the usual emergency system, connecting

the hotline (ups, battery bank) to the team.

ANALYSIS COST


35/37

ANALYSIS COST.

Then the difference between the budget shown excluding and including automaticcontrol of lighting in the room FIUN:

Estimated Cost Subtotal Facilities Electrical(without light controlAuto)

$ 14,002,120

AIU (25.3%) 3542536

TOTAL COST 17544656

Estimated Cost Subtotal Facilities Power (withlight controlAuto)

$ 15,574,354

AIU (25.3%) 3940312

TOTAL COST19514666

Considering the use or control system, there is a difference of $ 1,970,000 (about $1200) so that it can be said that it is a relatively low cost compared to the reversal ofthe lighting. (See attached budget).

CONCLUSIONS


36/37

CONCLUSIONS

In the selection of alternatives is chosen alternative 2 (GE 48 W LED 1'x4 ') sinceit presents better results with levels of 500 lx on average and uniformity of 0.708and UGR 20. Its energy efficiency is 8.41 W / m2With 10 luminaires.

Adding daylight to the design, you can get a value of energy efficiency of 4.08 W /m2, With 5 lights in operation, and five luminaires off to the day, with an averageilluminance of 695 lx, which represents the day saving up to 50% of energyconsumption.When automatic control of lighting FIUN room, could increase energy savings,since a more accurate and real-time monitoring would be conducted according to

the minimum requirements set illuminance, and even could dim or turn off all lightsin case sufficient to cover the entire room daylighting is present.The emergency lighting system can be done with the same normal lighting, takinginto account the recommendations given by the manufacturer.Considering the use or control system, there is a difference of $ $ 1,970,000(about $ 1200) so that it can be said that it is a relatively low cost compared to thereversal of the lighting, so worth investing.The modernization project lighting the room FIUN National University can be aviable project, given their future savings.
