The densification of urban areas without proper planning limits access to daylight. This study evaluated the influence of distance between buildings and solar orientation on the availability of natural lighting in a deep environment in Santa Maria, in the state of Rio Grande do Sul. A room of dimensions 2,55 m (facade) X 4,80 m was evaluated, located on the second, fourth and sixth floors of an eight-story building. The surroundings presented two distances between buildings and four orientations. The mean daylight factor (MDF), spatial daylight autonomy (sDA) and useful daylight autonomy (UDI) were evaluated by computer simulation using the DIVA plug-in for Rhinoceros. The parameter with the greatest influence on the metrics was the height: higher floors had better availability and distribution of daylight, while lower floors had less availability and worse distribution. The solar orientation with the best availability was to the South, due to the contribution of indirect lighting, reflected in the surroundings. The increase in distance between buildings positively contributed to the levels of daylight, with greater influence on the lower floors. The work can contribute to the design of buildings and urban planning of medium-sized cities in the process of urban densification.
