  The paper presents open-source computational workflows for assessing the
"Exposure to sunlight" and "View out" criteria as defined in the European
standard EN 17037 "Daylight in Buildings", issued by the European Committee for
Standardization. In addition to these factors, the standard document also
addresses daylight provision and protection from glare, both of which fall out
of the scope of this paper. The purpose of the standard is stated as
'encouraging building designers to assess and ensure successfully daylit
spaces'. The standard document proposes verification methods for performing
such assessments, albeit without recommending a simulation procedure for
computing the aforementioned criteria. The workflows proposed in this paper are
arguably the first attempt to standardize these assessment methods using
de-facto open-source standard technologies currently used in practice. The
approach of this work is twofold: establish that the compliance check can be
systematically performed on a 3D model by a novel simulation tool developed by
the authors; and highlighting the additional assumptions that need to be
implemented to build a robust and unambiguous tool within existing open-source
frameworks.
