Solar Panel Paint

Questions about buildings with solid glass exteriors.?
Are buildings with solid glass exteriors harder to heat and cool, or no because the glass can be tinted and double painted? If they are harder to heat and cool, why are so many buildings built like that today? Can you make a building look as if it has a glass glaze but actually have the inside walls not be walls of windows??? Don't many green buildings have solid glass exteriors? If they are actually not green, could they be with renewable energy, Solar Panels, and stuff like that?
They can be Triple Glazed so the insulation can be better than other designs
Using glass outer layer with a heavy tint say ... bronze, will be enough for the outside to look glazed yet the inside can have plaster board walls.
Such wall can also be 'green' if they incorporate Solar Energy collection either electrically or by heating water.
