Hi !


I decided I countinue my Thesis about Sustainable (energy saving) architecture. Possibly can somebody that measuring absorbtion/reflection/transmission of material in real life is possible? and how to?

It's certainly possible to do all the measurement, and is a critical part of material design, particularly optical materials. To do the measrements accurately, you need proper lab equipment, such as spectrometers and light detectors, but most information you might need for architecture, using existing materials should be available in data tables you may find online. In fact, the parameters will be programmed into the rendering engines in truespace to do the raytracing.

I am going to guess you mean in regards to light rather than sound or heat? If so, these web pages may point you in the right direction.
