ABSTRACT. Daylight design in architecture is used to provide ade~uate lighting to the interior and to exclude unwanted light from the room. of perception has led me to the contemporary notion of light as. 'information', most . the ingeniously designed daylight concept that al- lowed the architects to. fully integrated into the architecture and conceptual design. understanding of daylight and the ranges of lighting and privacy that humans need to thrive.

They are concerned with enhancing the appearance of architectural spaces and elements.

When people go to a theater to see a play or musical, they are expecting an experience before the show even begins. They want to see a beautiful chandelier welcoming them in the lobby, lavish wall sconces lighting the hallway to their seats, and the area around the stage to be lit to accentuate statues, pillars and other architectural features.

To enhance vertical borders for example, light should be directed towards wall surfaces. If there is a wall that is a different texture, or simply one that the occupants should notice more than others, wall washing is a great tool Image A. It will draw attention to the wall and make it appear as its own architectural element instead of a piece of an entire room.

How Light and Architecture Work Together

This can be used in retail locations to draw more attention to wall displays. Horizontal borders can be emphasized by illuminating the floor and ceiling.

By lighting the floor, objects and pedestrian surfaces are lit. This is particularly important in dark spaces such as movie theaters and night clubs. The ambient and accent light levels are so low that not enough light reaches the floor, thus requiring the floor to be illuminated Image B. Executed properly, this can act as task and accent lighting.


If light needs to be diffused in the room, lighting the ceiling can be a successful strategy. It helps create a uniformity of light throughout the room and provides proper light levels without the use of direct light on objects. Lighting pillars, archways, textures, etc. Light can help with this problem by making those elements more obvious. This tactic can be used for interior and exterior lighting applications. Image A Image C Common Architectural Elements Architects use many different types of materials to alter the way light enters a building and the way artificial light interacts with interior architecture.

One of the most common structural materials is glass. Natural colors can change throughout the day as the sun reaches different points in the sky, thus altering the colors of light entering a building.

The look of a building at noon can look completely different than the same building when the sun is rising or setting. The spaces between the petals are made of transparent glass and act as skylights. The inside of the petals are lined with translucent white marble to let just enough light in during the day. At night, the artificial lights that are placed inside the petals illuminate, transforming the building. The use of reflective surfaces can also transform a space.

Architecture and Lighting Design, 1st Edition

When light interacts with reflective floors, ceilings and walls, it can be perceived as an architectural element itself. Lighting on walls that continue to the floor can create dimension in a short hallway or small room and can add a futuristic feel to a room. Images retrieved from www. A great example of the use of daylight is the Baylor University Paul L. Foster Campus for Business and Innovation.

The main area of the building is lit with skylights that cover the entire ceiling. The goal for this building was to provide as much natural light as possible, while reducing unwanted light during various times of the day. To achieve this goal, the skylights include different angles to tailor to the different angles of the sun throughout the day. This helps reduce direct light that could cause discomfort. Higher levels of the building are set back slightly, exposing the lower levels to allow light to reach them.

There are also glass stairs to help the light move from one floor to the next. Architectural lighting is just as important as the architecture itself. The others in the two previous methods because of the design is based on light reaching the window from existence of important factors which are the speed two sources, the overcast sky and the exterior and the accuracy.

These programs are surface's contribution of reflected light. The clear blue sky, with or without sunlight, highly accurate flow chart in a recordable time. Through this introduction we position and the relevant scattering constants for can conclude that the calculation method of the the atmosphere. With clear sky considered a combination of the two previous conditions it is possible to work with actual values methods but with less error rate and high speed.

The most clear sky without sunlight, the direct sun's obvious and important aspect of daylighting contribution is omitted. Fig 6. Nagwa zaki, PHD thesis] 6. The spread daylight factor value in the space and compare it sheet can be used to obtain the required value of with the estimated values in the spread sheet. The daylight factor to be achieved in the design of main equation to find daylight factor is: space According to the required purpose.

The external reflectance component ERC. The internal reflectance component IRC. It is factors to be evaluated, among them are: particularly useful when the external obstructions are complex. Daylight Protractors: Which are devised primarily to simplify the calculation of the sky 3- The Waldram Diagram: This gives the sky component to enable daylight measurements to be component and the externally reflected component made From architect's drawings, In this respect under CIE sky and uniform sky.

It is particularly they are not design methods but merely useful when the external obstructions are complex an aid to design. Nagwa zaki, PHD thesis]. Robbins,] Fig 6. In the last 50 years, the institution of the daylight as it recommended those method of the daylight simulation has been programs as the best three programs in We developed to calculate the daylight factor.

These will review and talk about the following programs programs use the different conditions of the sky Ecotect, Daysim, Radiance. It features a designer-friendly 3D modeling interface fully integrated with a wide Generating vital performance-related design range of performance analysis and simulation information before the building form has even.

What really sets ECOTECT apart is the visual nature of calculation feedback and its support for very early stage conceptual design as well as final design validation. Designers can start Fig 6.

As the design environmental impact. The need to provide climatic control inside buildings to improve comfort levels and hence productivity is very desirable. However, the cost now gaining the attention of building designers of design or redesign to achieve the desired around the world. The problems associated with comfort levels has to be economically evaluated.

Fig 7. An area of this application will be a classroom daylight level in space depth the classroom located in Alexandria University, Faculty of leading the users to close the windows and use the Engineering, Architecture Department, in electrical lighting.

Administration building, fourth floor. This classroom has several problems such as low Fig 7.

Also the unequal distribution of natural reviewed and compare it to the other seasons to illumination due to the space, the daylighting know the best and worst time for the daylight in cannot reach in to big depth in the space so the the space, informing about or determining the daylighting covering small areas and users Fig space location is one of the required data in this 7.

The question is how to increase application or program to do the simulation daylighting level in the space? How to reduce heat process accurately or appropriately in order to Load for lighting?

These are the the year, it also can be reviewed throughout the required percentage to achieve the visual comfort different seasons. The simulation program will be used in this study to know the places which have poor and high lighting levels to find out the weakness points which need treatment and increase the daylight percentage and how to do it. The second step in this application after collecting data about the case study and problems facing it is to prepare This application works by entering the longitudes and latitudes and specifies the city location from the list of cities that lies in this region.

In order to have an accurate simulation process, all the input data like the drawings must be correct. This model should reflect the Fig 7.

Simulation results in March:- Fig 7. Simulation results in December:- Fig 7. Simulation results in June:- Fig 7. While well known to domestic applications that have roof space to floor area available, vertical light pipes VLPs and skylight technologies are now playing a part in rooftop locations such as supermarkets and where substantial savings in lighting have been achieved Fig 7.

The previous results of the simulation process in the classroom, and the counter maps show the main problem that face the classroom which result from the low rate of daylight especially in the Fig 7. Final conclusions process and which is the current fact.

The usage of The following points can be concluded from the the simulation programs output result in the previous results, the comparisons between desired objectives.


These techniques trend of architecture in the whole world to reserve increase the daylight rates in the classroom, and the non-renewable resource, make use of the the places that suffer from the lack of daylight.

The solar array of such off-grid PV system charges a rechargeable battery , which powers a fluorescent or LED lamp during the night. The use of heliostats , mirrors which are moved automatically to reflect sunlight in a constant direction as the sun moves across the sky, is gaining popularity as an energy-efficient method of lighting.
