Daylight is an essential element for both the built and natural environment. A careful design that acknowledges daylight performance can improve energy efficiency and environment protection, thus making construction more sustainable. However, allocating time to deeply evaluate all the aspects in a project might be challenging. In this framework, the aim is to analyze, through a specific designed case study, the different available options when it comes to manage daylight as a building material. Climate adaptation as a base for an architectural project is essential to achieve a regenerative evolution of the built environment. It should be holistically considered from the very outset, to conclude in a livable, sustainable and quality-designed space.  The aim of the present research is to thoroughly analyze daylight in order to use it as an input at the very early stage of an architectural project. Analyzing two different latitudes, Uruguay and Sweden, provided with a wide range of information, evidencing that assessing daylight is as complex as crucial.  Hence, the combination of academic methods with professional practice is key to design the built environment. By using an experimental cabin as case study, and with the support of the program Climate Studio, daylight is analyzed in these two different locations.
