VLL: for conducting complex lighting analysis in comparison to full-scale physical measurements.


	It does not require physical space;

	It does not require expensive equipment;

	It does not require laborious measurements;

	Reproducibility of the reference task is not a problem;

	The measurements are free from operator, who screens off the parts of the environment during measurements.

Slide 28

VLL: for simulating expensive laboratory equipment in virtual environment


	Perfectly diffuse material;

	Physical requirements, such as aperture in the sphere wall for the measurement purposes are not needed in virtual environments;

	Flexible size.

Slide 31

"To demonstrate that photopic luminance..."


	To demonstrate that photopic luminance is not sufficient alone to analyze luminous environment;

	To transform the recent research findings into current lighting practice;

	To devise a new luminous environment indicator

Remarks


	Restructuring in Architectural Lighting Analysis with:
		Transformation of complex indices from laboratory environments to real architectural applications;
		Transformation of expensive lighting equipment to general usage;
		Transformation of recent research findings into current practice;
		Generation of new indices;
		Transformation of psychophysical experiments from simple scenes to real architectural applications; and
		Transformation of lighting analysis from static lighting indices to dynamic lighting indices.
