That is a link to only one of their articles. Generally pretty buildings with lots of glass are inefficient (glass has a r value of about 2). Buildings that look like windowless Boxes with no windows can have an r value up to infinity. The easiest way to make a "green building" that has glass walls is to compare it to extremely inefficient buildings in the prebuild analyses. The perfect wall (perfect order of exterior wall control layers) makes for highly energy efficient buildings. https://www.buildingscience.com/documents/insights/bsi-001-the-perfect-wall https://www.buildingscience.com/documents/insights/bsi-001-t...
