Introduction
The term daylight is defined as the act of considering and adjusting windows, the light of the sky and the other remaining openings, and have the surface which reflects the sunlight whether directly or indirectly, can help and provide with efficient and effective atmosphere with lighting. The special emphasis is being placed on the daylight or direct sunlight at the time of designing the infrastructure of the particular building when the purpose is to optimize and improve the direct comfort and to eliminate or reduce the use of the energy to a considerable extent.
The energy consumption can be eliminated and decreased to a considerable extent when the consumption of artificial or man-made sources of electricity are decreased and this objective can be achieved by reduced consumption or by installing the requisite and fewer lights at the time when daylight is available, or by the practice of dimming or turning the lights off when not required, or at the time when daylight is present, this particular process of optimum utilization or sustainable use is known as daylight harvesting. The percentage of availability of daylight in the interior space of the building can be discussed and determined by the process of analyzing and measuring illuminance on the part of the grid or by considering the factor concerning the calculation of the daylight. Various computer technologies and programs that be like radiance permits the interior designer and architect to efficiently and rapidly measure and calculate the merits of the specified design. The response of human eyes to the light in the daylight is non-linear, so that the even and equal distribution or allocation of the light in the room results in the appropriate availability and
ightness of the light and it seems
ighter. The major and most appropriate source of daylight is the sun. The appropriate and efficient ratio of the direct light to diffuse the light directly affects the quality and percentage of light or the daylight (Christoffersen, Petersen, et.al., 1997).
Literature review
According to the perception of the various professors and authors and also the numerous departments related to the offices of energy have proved that approximately 32% of the total energy is consumed by the commercial buildings and residuals in the united states, and in the same more than one-third of the percentage is consumed because of the lights and substitutes of lights. The author is of the view that the consumption or to put it in another way, the usage of system of day light and putting the lights off when not required can help the society and will make it march towards the sustainable development and will ultimately conserve and save the natural resources and energy and will decrease the load on the energy generation. The cost of utility can be reduced to an extent when the system of daylighting is properly designed and implemented which will help both the users and generators as a whole.
Building background
The design of the building is a complicated and complex procedure at the time when the important and crucial decisions related to the various distinct systems concerning the building are to taken at the prior stage or to put it in another word at an earlier stage before the construction. For the spaces being particularly being the perimeters, a critical and integrated thermal and analysis being the lighting in the day time is requisite while designing the infrastructure, since the domains of the same are co
elated with one another. The consumption of the sunlight and daylight will lead to a critical saving in the utilization of the electricity of the lighting. As the technology is mending regularly and the various advancement in the technology in the building is transparent facades, and the numerous designs have been transformed to consume the changing fenestration and the various systems in used in the shading for optimistic control over the daylight and the benefits and gains from the solar systems. Presently, with the immense developments in the architectural sector have provided with numerous benefits and merits of the daylighting is re-engineered or re-defined and the requirement for the programs of simulation that combine and co
elate the thermal performance of daylighting is efficient and strong. This has resulted in the process of various research’s has integrated the thermal simulation and daylighting.
However, the various potential changes concerning the shading devices used in the operations with the help of the various systems in the automation while building is usually being avoided, this directly affects the respective shading design and supervision in the control process and examining the performance in the building is neglected and is not considered at the designing level, though the optimum and sustainable cooling and lighting balance in the energy among the lighting and fenestration can be consumed or utilized and recognized. Cu
ent researches have proved that proper design of shading and sway, when attached along with the various lighting components and various HVAC components, will crucially decrease most of the load on cooling and the level of utilization of the energy for cooling and lighting, just to ensure the optimum and best thermal and great conditions in the indoor.
Building dimensions
A completely air-conditioned outdoor office was situated in the northwest region i.e. 320° was being opted for building the same. The office is being constructed on the fifth floor in the seventh storied building with the following considered dimensions of 5.88 m (width) * 10.29 m (at the façade of the window) * 2.39 m (height). The working space is the considered monitored room for the staff members to work and operate the management of the office. an approximate of 14 ceilings are being mounted with the new and recessed fluorescent luminaries along with the diffusers with the set standard are being installed in the rows and specifically 4 rows in a parallel series on the facade of the window panel. The leftmost side of the office has a layout plan and a suitable design of the office. Each luminaire is unique and have its characteristics but is common in few regards like each one of them consist of about two 36 watt tubes made of fluorescent or to put it in another words is made up of fluorescent tubes with a unique and exclusive dimmable ballast present in the electronic tubes, which helps them reduce the light of the lamp smoothly and...
