Abstract

The present work is an investigation of some project variables such as geometry, windows size, quantity and distribution of artificial light. The parametric analysis tool is the ECOTECT software, that makes possible the spaces adequacy study and optimization of the energy used on artificial light. This parametric investigation is developed to an indoor 36m² office environment, where daylight is provided by one face, varying the size of the void; environment width and depth are the variables that makes difference on the illumination quality. As a starting point demanded by the NBR 54131 for workstations and circulations lighting levels were accessed. From these values were done analysis of energy consumption related to daylight availability and energy demand to artificial lighting to reach the regulations. To attribute evaluation levels to space related to geometry, activity and energy consumption was generated a matrix that relates geometry to consumption. From this matrix, limit proportions were established to wich the incident daylighting levels are suficient and from wich values adequation is necessary. From the study is possible to evaluate the better relation between geometry, lighting and energy.
