Lighting is one of the most important aspects of a buildings design. Lighting affects everything from the way we interact, to how comfortable we feel in certain spaces. Furthermore, its also one of the most energy-consuming elements of a building, so its important to design it properly from the start. There are many different types of lighting that can be used, such as natural lighting, artificial lighting, and accent lighting. Natural lighting is a free and environmentally-friendly source of lighting that is available from several sources, such as sunlight and skylights. Artificial lighting, such as fluorescent and LED lighting, is generally used in areas that do not have access to natural lighting. Accent lighting, such as spotlights and recessed lighting, is used to draw attention to certain aspects of a room. Designing a lighting plan requires careful consideration of the buildings design, as well as the specific needs of the people who will be using the space. Task lighting, for example, should be provided in work areas so that users can see what they are doing. Ambient lighting is also important, as it helps to set the mood in a room and can generate a feeling of comfort. The proper use of lighting can have a great impact on the overall design of a space. By carefully considering the types of lighting that are used, designing an efficient lighting plan for a building can result in a more pleasant and productive environment.
