Lighting design is a crucial aspect of building design, as it can significantly impact both energy efficiency and user comfort. Lighting design for energy savings and lighting design for comfort are two distinct activities that require different approaches and priorities. Lighting design for energy savings focuses on reducing the energy consumption of a lighting system, while lighting design for comfort emphasizes the aesthetics of the light and ensuring that the general illumination levels are suitable for the intended use. To achieve energy savings, lighting designers must consider the type and quality of lighting, luminaires, and control systems. They may select energy-efficient light sources, such as LED bulbs, or use intelligent lighting controls to turn off lights when they are not needed. They may also design layouts and strategies that minimize energy consumption, such as using task lighting instead of general lighting or providing daylighting to reduce the need for artificial lighting. On the other hand, lighting design for comfort requires designers to consider the visual comfort of occupants and the atmosphere of the space. They may select luminaires that provide good visual comfort, such as those with diffusers that reduce glare and improve uniformity. They may also use light to create a pleasant atmosphere and an illuminated environment, such as using warm-colored light to create a cozy feeling in a restaurant or using colored light to highlight artwork in a gallery. In summary, lighting design for energy savings and lighting design for comfort require different approaches and priorities. While energy savings focus on reducing energy consumption, lighting design for comfort emphasizes the aesthetics of the light and ensuring that the general illumination levels are suitable for the intended use. To achieve either objective, careful consideration must be given to the type and quality of lighting, luminaires, and control systems, as well as the layout and strategies of the lighting system.

From a creative and aesthetic perspective, lighting design for energy savings and lighting design for comfort can be seen as having fundamentally different objectives. Lighting design for energy savings is focused on reducing the energy consumption of a system. This may be achieved by selecting energy efficient light sources, using intelligent lighting controls, or providing carefully designed layouts and strategies. In contrast to this, lighting design for comfort focuses on how a space is illuminated and how this influences user experience. Here, designers may select luminaires that provide good visual comfort, or use light to create pleasant atmosphere and an illuminated environment. This may include the use of different colors or intensities of light, depending on the purpose of the lighting system and the desired outcome.

Lighting design plays a crucial role in energy efficiency and user comfort. Electrical lighting accounts for the largest portion of commercial electricity use and is a prime target for energy savings initiatives. Lighting design for energy savings and for comfort can be two distinct activities depending on the priorities of the designer and the needs of the user. Lighting design for energy savings focuses on cost savings, life cycle costs, and meeting or exceeding building codes. In contrast, lighting design for comfort emphasizes the aesthetics of the light, ensuring that the general illumination levels are suitable for the intended use, and providing visual comfort to the occupants. In either case, careful consideration must be given to the type and quality of the lighting, the luminaires and control systems, and the layout of the lighting system.
