The entry of natural light into environments has always played an important role in architecture. With the increasing search for more sustainable solutions that promote well-being, this aspect has started to receive even more attention in residential projects. Among the alternatives used to increase the brightness of the home is overhead lighting.

For architect Isabella Nalon, who implements the resource to add this privilege to projects, bringing natural light into the home is part of a set of strategies that seek to improve the performance of environments, both from a functional and sensorial point of view.

How overhead lighting works

Zenithal lighting is a technique that implements openings in the roof of buildings to allow natural light to enter. Unlike conventional windows, which capture from the side, this type of solution contributes to the light directly from the sky, creating more homogeneous and, often, more intense lighting.

It is based on this logic that different elements can be applied, such as sheds, lanterns, domes and the skylights themselves. “Each of them responds to the specific needs of the project, varying in shape, light intensity and thermal behavior”, comments Isabella Nalon.

Where it is usually applied

In residential projects, overhead lighting, through skylights, is usually recommended for areas with shorter stays. Bathrooms, corridors, entrance halls and internal courtyards are frequent examples, as they benefit from the natural light without requiring constant light control.

In commercial and industrial buildings, the architect explains that the solution gains relevance by compensating for the absence of side openings, contributing to a better distribution of light over large areas.

Benefits beyond aesthetics

In addition to the benefits already mentioned, Isabella Nalon reports that overhead lighting enhances the architectural design, reduces dependence on artificial lighting throughout the day and contributes to the well-being of residents.

“When well applied, natural light transforms the experience within the space and also contributes to the energy efficiency of the building”, he observes. Another relevant point is the appreciation of the property, as well-lit environments tend to be more attractive to buyers.

Technical care makes a difference

Within the overhead lighting strategy, the skylight requires attention based on several factors. According to the professional, solar orientation, the size of the opening and the materials chosen directly influence the thermal and lighting performance of the building. environment.

She also says that the continuous incidence of light is positive, but requires control in some cases. In environments such as bedrooms and living rooms, installing curtains is a common solution to regulate the volume of light throughout the day. Lighter fabrics allow partial filtration, while options with a blackout effect guarantee total blocking when necessary.

With regard to maintenance, the architect recommends periodic cleaning of surfaces to avoid loss of efficiency in the entry of light. Furthermore, it is necessary to provide, even in the design phase, access to coverage to facilitate this care over time.

Materials and trends for overhead lighting

Glass remains the most recommended material for skylights, mainly due to its durability and thermal performance, although it presents a higher cost. Polycarbonate and acrylic are more affordable alternatives, but they may require maintenance over time, especially depending on weather conditions.

In the field of design, skylights follow the evolution of architecture and also begin to assume a more striking aesthetic role. “Metallic structures, varied formats and solutions that create light and shadow effects in environments are among the current trends”, reinforces Isabella Nalon. In some cases, it can also incorporate ventilation systems, expanding its functionality and contributing to environmental comfort.
