Artificial lighting in buildings pdf

At the meeting room that is by using general lighting system. The general lighting system provides good enough light spreading to illuminate the reading and writing areas above the workbench. In the bedroom is by using a combination of direct lighting in the form of general, task, and accent lighting.

One important part of lighting is the armature, which houses a lamp that embodies the light source. The function of the armature is to manipulate the light produced by the lamp as desired.

Some research results prove that the armature design can be the attraction of visitors to commercial buildings. Here are the results of research in some commercial buildings: A. Unique armature design, eyecathing.

The establishment of this room center is a point of interest, a hanging lamp mounted using a custom made design, made of woven rattan that extends into its own beauty and adds a traditional touch Nabella Alatas, Anwar Subkiman, Figure 3. General Lighting in section d implements a decorative armature of Japanese culture-shaped paper ball, as well as adequate lighting, good for eye health, as well as the element of romantic atmosphere by showing the aesthetics of the lamp Nugraha Saputra, Edwin Widia, Figure 3.

Lighting decorative lighting is able to create a warm atmosphere and dramatic shadow effect so that more visitors are interested Anastasha Oktavia et. Artificial lighting has the effect of making a product look more memorable.

The use of spotlight lights with moderate lighting is able to provide visitors with a comfortable atmosphere; With such psychological circumstances will invite interest to buy the product Mohamad Putra Rianto Effendy, Abraham Seno, Figure 3.

Spotlight illumination the effect of the lighting focus on the object and wallwash the lighting that is highlighted on the wall, the effect is evenly on the collection object as a space shaper. Artificial lighting is not only to illuminate collectibles, but also affect the atmosphere of the room and its appearance, it implies that lighting will affect the appreciation of the gallery visitors Muhammad Fauzi, 3.

The elements included in the category include interior lighting, walls, floors, ceilings and colors. From various studies proves that the color of light raises the perception of visitors to commercial buildings.

One of the results of research conducted to see the role of artificial lighting in the formation of atmosphere and image of commercial space case study on the interior of some thematic restorant in Bandung concluded that: "Selection of yellowish light color will create a warm atmosphere, the use of white color from the source Neon or fluorescent light will produce a clean and bright atmosphere, while the use of light blue, red, or green will produce a fresh atmosphere Mila Andria Savitri, The same thing was also conveyed by Nabella Alatas and Anwar Subkiman based on their research at Sambara Bandung restaurant that "color halogen lamps create a warm and inviting impression".

Research on other commercial building objects also yields the same conclusion. Jocelyn Hadianto, et. Lighting as an atmosphere builder can help in influencing the visitor's desire to buy the products sold B. The predominantly yellow artificial lighting creates a pleasant, intimate atmosphere and makes the room feel more cramped. A review of the lighting system that affects visual comfort is also performed by Nur Laela Latifah, et.

The study was conducted with the aim to know the visual comfort that is formed so as to know the worth and not the showroom. Special color of light and reflection of the color, concluded that: "The application of artificial lighting system is good enough, because the use of white light color neutral light, so the color on the object looks like the original". The study of artificial lighting effects for commercial buildings was also carried out by Muhammad Fauzi , he observed the Jakarta textile museum and Pekalongan batik museum as the object of his research.

Artificial lighting analysis described as follows: for special lighting task lighting , the type of lights in the Jakarta textile museum using spotlight and downlight, while the Pekalongan batik museum using spotlight lamps. As for general lighting general lighting type of lights in the museum textile Jakarta is ideal, while the Pekalongan batik museum using the ideal light but not maximal.

From the observation and assessment of the researchers concluded that "Jakarta Textile Museum and Pekalongan Batik Museum has not been ideal on all elements - interior elements and lighting". The important researcher's recommendation is "Lighting using LEDs makes the light clearer and focuses gently on visibly improved artwork, color and depth and no harmful UV rays emitted. Artificial lighting properties that can be manipulated, in addition to strong light and light colors, as well as direct, indirect light direction.

In a study titled lighting review at Sambara Bandung Restaurant, Nabeela Alatas and Anwar Subkiman observed lighting system in several areas such as reception area and reservation. In this area the applied lighting is the arrangement of the recessed lights on the ceiling. Based on the results of the research, it can be understood that the directed lighting becomes one of the ways to produce optimum lighting quality. Research conducted by Nur Laela Latifah, et.

The result of research is only based on the opinion and observation of the researcher, so the value of subjectivity is quite high. Based on these observations, the researchers concluded that "the glare that occurs in this gallery is not dazzled, so it does not interfere with visual comfort to visitors".

Although the results of the research are less accurate, it is understood that the limitation of light is not blinding the eye into one of the lighting factors that simultaneously influence each other in producing optimal lighting quality. Conclusion 4. Good lighting system and design B. Spatial conditions and atmosphere C. Light color and color reflection D. Limitations for light not to dazzle the eye 4. Factors that have not been subject to study by researchers include: A.

Light density distribution luminance distribution B. The quantity or amount of light on a particular surface lighting level 4. Artificial lighting systems and design are good B. Limitations for light not to dazzle the eye E. Light density distribution F. Quantity or amount of light on a particular surface G.

Other factors that may affect the optimization of the role of artificial lighting in commercial buildings. With comprehensive research it is possible to strengthen or even the occurrence of anomalies of existing theories. References Alatas, Nabeela dan Anwar Subkiman.

I Saputra, Nugraha dan Edwin Widia. I Savitri, Mila Andria. Sometimes called tubular day lighting devices or TDDs , their day lighting effect relies on their ability to capture direct-beam sunlight, transmit it down a highly reflective light well and diffuse it at ceiling level around the room.

Its diameters ranging from about 10 inches for residential applications to 22 inches for commercial buildings. Materials - Made from acrylic or polycarbonate formulated to block ultraviolet rays.

An aluminium tubing system is there where the dome captures and redirects light rays. Figure 7 Tubular skylights 3. It provides maximum daylighting and air circulation. It evolved in India during Mughal, Portuguese and European influence.

In the southern states of Kerala most ancestral house have courtyard according to the vaastu shashtra. Orientation of the building is an important factor to get ample amount of day lighting in the workspace.

Solar passive architecture should be taken into considerations so that the use of artificial lighting will be reduced and energy conversation can be done. Energy-efficient windows and also advance lighting design helps to scale back the requirement for artificial lighting during daytime without causing heating or cooling problems. Obstructions block motion detection and reduce its effectiveness.

Ultrasonic sensors transmit sound above the range of human hearing and monitor movement patterns. Hybrid Occupancy Sensors utilize both passive infrared and ultrasonic technology, but are usually more expensive.

Time controls save energy by reducing lighting time of use through pre-programmed scheduling. Advantages of daylighting Energy conservation - Day lighting minimize the use of artificial light source, reduces electricity and HVAC heating, ventilation, and air conditioning costs. Day lighting does not generate heat when controlled properly whereas electrical appliances produce high level of heat.

This leads to energy conservation. Which one is better for workspace and home — day lighting or artificial lighting? According to the typology of the building daylight and natural light is determined.

In office space more light is required to do work so more lighting is required. And in residential building less lighting is required as compared to office building. So sustainable strategies can be used in both to decrease the energy load of the building. As it is understand that in the residence plan courtyard planning is done so daylight is available in the building while in office plan it is understand that day lighting is covered at places where openings are there and at some areas it is not sufficient to do work.

So hence we can say that in office combination of both daylight and natural light can be done so that energy is conserved.

Energy efficient lighting fixtures should be used. In residential proper amount of daylight is provided by using sustainable strategies which help in energy conservation. In conclusion, this study presents a serious endeavour to apply sustainable architectural design strategies to utilize natural daylight. The concept of sustainability has to go beyond the exclusive optimization of ranging energy performance factors which lead to a reduction of consumption and environmental impacts.

It must also acknowledge the physical, physiological and psychological human needs. Sustainability calls for long-term changes through the interplay of several interconnected systems, adopting an integrated approach to architecture where a decision in one area can influence another. In this context, daylight is an intriguing aspect of design in which environmental, energetic, aesthetic, social, cultural, financial and human aspects simultaneously work together.

Thus, this first study makes it possible to develop various evaluation methods that are simple to implement and provide easily workable results for the natural lighting from a quantitative and qualitative point of view. Workplaces that are dependent on artificial light is less productive, less healthy and far less energy efficient than their natural counterparts.

Combination of artificial and natural lighting are being used in most energy efficient building. Day lighting cannot completely replace artificial lighting in workplace. Penny, Janelle.
