2. Layered design[2]​

Layered design provides a framework for understanding and achieving composition and aesthetics in lighting design. A designer must first determine which objects and surfaces require lighting and develop a visual composition using multiple layers of lighting. To understand the importance of the layer, it is important to recognize how humans interact with light.

The following light layers are identified in order of importance and visual impact. Each layer has unique responsibilities for illuminating certain visual tasks; however, the layers often work together to illuminate parts of the space.

- Spot Light: Typically used to highlight vertical surfaces and three-dimensional objects, including architectural features and details.

• Work light: It is used to illuminate specific activities that are carried out in a certain space.

- Daylight: The daylight available in a space must be taken into account, so that opportunities to reduce artificial lighting can be realized in the early design process.

• Decorative light: its main purpose is to decorate the space and attract attention.

- Ambient light: Provides background lighting that helps create the atmosphere of the space.

3. Selection

The first two steps have provided enough information for a designer to begin selecting the appropriate light sources and luminaires for the space that will meet the established criteria.

Light sources are selected in terms of the qualities of the light they produce and how the light is generated.

Achieving the designer's aesthetic vision may involve techniques ranging from the simple to the complex, and luminaire selection must be compatible with the intended approach.

4. Coordination

The designer brings together all the design criteria established in the previous steps and coordinates those elements with the work team, to ensure that the lighting is designed and installed to comply with all applicable codes and with the needs and expectations of the clients.

A starting point for lighting design[4]​ is knowing how much light is required. All countries have different standards for the lighting levels required to carry out different activities, from lighting a hallway, an office, a school, to what is needed to do very specific jobs.

The amount of light on a surface or illuminance is measured with a lux meter, its unit of measurement is the lux (lumens per square meter).[5]​.

Generally, as a regular measure, 100-150 lux are needed for hallways, 300-500 lux for tables in offices and schools, 500 lux for a soccer game, etc. A lighting designer must always consider these minimum requirements, however this is not a formula for a lighting design since people's perception and their visual comfort is the most important thing for a good design.

The starting point of the lighting design is to set the illuminance—measured in lux (lm/m²) with a lux meter—: 100–150 lux for hallways, 300–500 for office tables and schools, and ~500 for a soccer game; are normative minimums, because perception and visual comfort rule a good project, according to Mariner 1893").

Since lighting was invented, the switch has been essential. Even the candles and gas lamps were turned on and off and sometimes even dimmed. Lighting controls allow occupants of a space to adjust the level and quality of light based on their personal preferences and needs. In addition to improving the ambiance of a space, controlling light helps save energy.

To ensure that lighting meets all safety, accessibility and energy requirements, there are five types of similar codes and regulations that affect building lighting.

• Electrical codes: are designed to ensure that buildings are safe.

• Building codes: are designed to ensure that buildings are structurally safe.

• Energy codes: are designed to ensure that buildings use the minimum amount of energy to operate.

• Accessibility codes: are designed to ensure that buildings can be used by all people, including people with disabilities and mobility issues.

associated with aging.

• Health Codes: Hospitals and nursing homes require health codes to provide minimum light levels in certain locations.

In any design experience, there are no correct or perfect solutions to solve lighting design problems. In most cases, several solutions can be successful. The designer must strive to find viable solutions that satisfy the functional, aesthetic and psychological needs of the client and users.[2]​.
