Eco Friendly Glass Clad Buildings

The Green Design Award 2011 Winner in the USA

Visually dynamic, or a blot on the landscape? You be the judge. But the clever use of grey Low E glass and blue insulating glass had it being selected as the winner of the above award.

Let us look at it from the inside:
The property showcases 9.5 foot high, floor-to-ceiling glass allowing for 92% natural light and unobstructed mountain views, and also affording sweeping city views for the tenants.

In the words of Ron Izzo, associate principal at architectural firm RNL and project designer on the building:

“. . . We began our studies by looking at the building in the uniform skin of precast and glass. Using a subtractive design process, we created voids and filled them in with the contrasting blue glass. This gave us the right visual balance with the grey glass set in a precast spandrel. Each blue glass module is a repetitive derivative of the smallest module within the building, which on a standard office building is typically five feet. The modules then combine to fill the column bay; this is typically 30 feet from column-to-column and 14 feet from floor-to-floor. The pattern grows or shrinks in multiples of these structural bays, evolving around all four sides and spreading across all elevations. All of the blue glass modules stand off the skin.”

To create pleasant, day-lit interiors without glare or thermal discomfort, the glass fabricator helped create a unique glazing solution: Grey Insulating Glass with a Low E coating is the primary glass. The glass has a visible light transmission of 23% to allow enough light inside without glare or significant solar heat gain. This glass is broken up by large squares of Blue Insulating Glass. The blue glass has a lower light transmission (8%) than the grey, but casts a beautiful contrasting light into the building. The grey glass has a solar heat gain coefficient (SHGC) of 0.23 while the blue has a SHGC of 0.16. This high solar performance was chosen to reduce overall internal energy consumption.

I can appreciate that from the point of view of the persons working inside the building it could have a pleasant ambience, but IMHO, from the outside, it is still a not-particularly-attractive glass box.
