Abstract: The Brazilian National Standard for the assessment of residential buildings' performance presents limitations regarding metrics and methods recommended for daylight assessments. This paper presents the proposed updates for the standard, along with the development of a simplified simulation-based tool - DL Abacus-. The spatial Daylight Autonomy of 36,000 parametric cases was obtained through CBDM simulations. The abacuses were developed based on the most restrictive cases meeting the proposed targets. We developed a set of 9 abacuses, separated by latitude and visible transmittance. The tool will be useful for the standard application, especially in low-budget projects and remote regions of the country.
