The physical properties of glass are invaluable and unequaled when it comes to the architects material palette. From the time of the cathedrals and the the brilliantly colored stained glass that served a functional and didactic purpose, to the modernist liberation of the floor plan and the exquisitely-framed horizontal views provided by ample windows, architects have turned to glass to achieve not only aesthetic but performative conditions in their projects.

Today, Architects face an increasing array of choices in specifying and designing with glass for building facades, as glass manufacturers propose a greater variety of colors, textures and patterns than ever before. A wider range of coatings and treatments has also been developed, allowing for a finer selection of glass panes with a combination of light transmittance, reflectance and absorption to meet the needs of outstanding architectural projects. These options affect the aesthetics and energy performance of the glass, and therefore of the overall building.

Thanks to advanced calculation tools, energy performance can now be anticipated accurately, but the graphic representation of glass is still a challenge, and yet a crucial need for architects.
