Coupling Natural with Human Made Lighting, a predicament in which accuracy is at stake

Nature has the power to be destructive with its unlimited force.  In terms of lighting, sun has the power to be destructive as to the visual comfort in rooms of a building.

Yet, sun-shading constructions, which indiscreetly block even the diffuse light of the sky do not fulfill the objective of our connection to the natural environment and of the stimulation of the sense of time, induced by daylight dynamics.

Thus, when it comes to adjusting electric lighting to a daylighting ambience, a proper control of the deprived of solar radiation abundant lumen package of the sky is of pivotal importance, mostly with regard to the maximum values of daylight. These values shouldn’t strikingly exceed respective target values of illuminance in rooms adjacent to an atrium for the sake of balanced lighting, as the latter can’t be acceptably acomplished, if electrical lighting adapts to a prohibitive for conservatory aspects in museums and exceedingly high illuminance level of daylight.

In this precarious predicament; accuracy is at stake. This is why, we are inserting Bidirectional Scattering Distribution Function – BSDF information into the 3D simulation model to gain a truly representative insight into the real interaction of light among materials of various optical properties.

On the other hand the above accuracy-minded approach to lighting design for the New Archeological Museum of Sparta has been just a means to an end, in this culturally specific case dictated by the aspiring vision of mor-architects, s. here.
