Resumo: | The development of the urban space has a great impact on daylight availability. Urban design can improve the use of daylight in buildings. Climatic conditions influence the availability of daylight considerably and should be taken into account by Urban Codes. In the humid tropic, the sky factor may decrease due to the use of the solar protection. That has been the main parameter to control the influence of obstructions on daylighting of buildings. This loss can be compensated by the considerable availability of reflect light. The present work aims to analyse the influence of the reflect light on luminous performance of buildings in the humid tropic. It was evaluated the efficacy of the sky factor parameter, the influence of opening orientation and the contribution of the reflect light on ground and obstructions. The methodology is a comparative study for different urban space models by computer simulation with TropLux. The simulations were done for Maceió-AL with partly cloudy sky. Results showed a great contribution of the reflect light for tropical daylighting. The use of sky factor parameter showed more effective when used together with opening orientation. More appropriate approach for Daylighting Code in the humid tropic should pay more attention to reflected light on the ground and obstructions as well as to opening orientation. This work aims to contribute in some way to create urban design guidelines that help designers and planners to develop urban models that allow a proper use of daylight in the humid tropic. |
