"Good lighting elevates mediocre architecture, and bad lighting ruins even the best design." This famous quote by Oscar Niemeyer says it all about the importance of lighting in environments. In fact, lighting is a very powerful element in architecture and interior design. With it, we can highlight architectural details or prominent features, we can focus or blur parts of the space, and it has the power to transform an environment, creating light or scenic settings, depending on the amount and intensity of light used.
Another crucial feature of lighting is its ability to influence our bodies, causing changes in mood, well-being and health, as well as affecting our decision-making. Light conveys sensations: through its correct use, we can create environments of relaxation, stimulation, spaciousness or even focus.
What other element available to interior architecture and design has this power to alter our feelings and state of mind? Through well-planned lighting techniques, we can influence audiences to be happier or more relaxed, creating countless scenarios. It is incredible how much control lighting design can have over us!
In order for lighting to create differentiation and achieve its objectives, it is essential to take three technical factors into account:
Control over light levels should always be coordinated with the daily routines of users, their habits, and usage schedules.
Colour temperature is a determining factor in how we see objects and interpret colours throughout the day.
Along with temperature, light intensity is also directly related to our emotions.
Although seemingly technical in nature, lighting design is a fundamental aspect of any project. When well executed, it is a powerful ally for interior designers and can be a great asset.
A project that has a professional dedicated to lighting design benefits from:
That said, it is clear that an interior architecture or design project must always be accompanied by a good lighting design, executed with detail and care, with specific attention to the experience of the environment and the correct use of lighting.
It is essential to consider this component right at the start of the renovation or construction, together with the interior design, to facilitate efficient execution and proper use of the products. A well-researched architectural design makes a huge difference in the end. Specific light fixtures with efficient bulbs, positioned in the right places, can work wonders.
Even in later stages of an interior design project – which includes defining the layout, choosing furniture and other aesthetic elements – lighting remains an important consideration. The designer's role is to balance natural and artificial lighting to provide the greatest aesthetic and sensory comfort.
When the project is no longer undergoing major structural changes, it is necessary to make creative adaptations to what already exists, correcting errors that could have been avoided if they had been thought through in a timely manner. At this stage, the work is surgical and precise, requiring technical expertise in choosing the colour and temperature of the light, according to the emotions that one wishes to arouse or calm in each environment.
A lighting design project involves the study and planning of a space’s lighting, defining the location, type, intensity, color temperature, and orientation of the light sources. In an architectural and interior design project, lighting is conceived in conjunction with the architecture, materials, fixtures, and intended use of each space. The goal is to create lighting that is functional, comfortable, and aesthetically integrated—lighting that enhances the space and the experience of those who inhabit it.
Lighting directly influences how we perceive a space—its volumes, materials, colors, and architectural elements. A lighting design allows for an integrated approach to lighting from the very beginning, combining general, task, indirect, and accent lighting according to each space. A well-planned solution improves visual comfort, enhances the architecture, and creates different atmospheres, making lighting an essential part of the language and experience of an interior design project.
Direct lighting falls directly on a surface or area and is suitable for tasks that require greater visual precision, such as in a kitchen or work area. Indirect lighting is reflected off walls, ceilings, or other surfaces, creating a softer, more enveloping light. Diffused lighting distributes light more evenly, reducing harsh shadows. Accent lighting, on the other hand, is used to highlight specific elements, such as works of art, decorative pieces, textures, or architectural details. Combining these types of lighting allows you to create balanced and dynamic environments.
Color temperature should be chosen based on the function and desired atmosphere of each room. Warm light, typically around 2700K, is suitable for spaces where comfort and coziness are desired, such as living rooms, bedrooms, and sitting areas. More neutral color temperatures may be appropriate for kitchens, bathrooms, or workspaces, where a more accurate and clear perception of colors is important. The choice should, however, always take into account the architecture, materials, and natural light of the space.
The lighting design should be planned during the early stages of the architectural or renovation project, before the electrical work, ceilings, and other elements that may affect the lighting are installed. Defining the location of light fixtures, controls, equipment, and lighting solutions in advance allows for the integration of lighting into the architecture and helps avoid changes later on. This advance planning is especially important when there are crown moldings, recessed lighting, indirect lighting, custom woodwork, or other custom solutions.
Yes. A well-designed lighting plan can significantly improve visual comfort and contribute to a more efficient use of lighting. By determining the appropriate number, location, and intensity of light sources, you can avoid installing too many fixtures and reduce energy waste. The use of different circuits and control systems also allows the lighting to be adapted to the needs of the moment, creating more comfortable, functional, and efficient environments.
