Resumen:
Abstract: Transition spaces are characterized by possessing high gradients of luminances, which
implies a great demand for the users' visual system functioning. This work poses the hypothesis that a
satisfactory descriptive indicator for this kind of scenes could be a "modelling factor" (MF) defined
from cylindrical illuminance (Ec) and horizontal illuminance measures (Eh). That MF would provide
information about the depth and dimensionality of objects present in the scene. With the objective of
monitoring solar light behaviour and its interaction with the transition space, measurements were
taken during June, winter solstice (21 June, 2008 and 2009) under clear skies at the beginning and at
the ending of the working day (9:15hs and 13:00hs). In addition to that, another measurement was
taken under a June overcast sky at 13:00hs, to have a comparative parameter. We found that the most
unfavourable condition was produced at 13:00hs (midday) whereas for the 9:15hs we found MF
values that fall into the optimum range; except for only one point from June 2008 which was out of
range. The Modelling Factor is a valuable transitional space assessment tool which allows the
integration of the most relevant factors intervening in this kind of spaces. This tool also takes into
consideration the characteristics of the human visual system given that it proposes a certain range
where lighting conditions allow a correct appraisal of the space and object modelling
