A double-glass skin: cost / benefit equation (066)
Beyond the indisputable formal possibilities of a double skin glass facade: blurring the structural and / or functional order, giving uniformity, vanishing the volume limits melting them with the sky, and so on; a double skin glass facade contributes little to improve thermal aspects in our climate.
In the case of this building, its disposition in the southwest and west facades clearly indicates that the objective when placing the second skin was protecting from the excess of solar radiation. Is it a second quite transparent glass the best option for that? Maybe the fact that those two facades face noisy streets is the point. Or maybe the objective was as simple as disguising the facade of the pre existence in the ground floor.
