The team pushed the design further by slicing open the vast roof and building a series of carefully placed light shafts. The design will provide daylight for 100% of the interior, a far cry from the cave-like working conditions in the building now. The energy savings start to really add up when artificial lighting is minimized but to get to net zero the team proposes to eliminate all desktop computers and use efficient cloud servers for data management.
Of course, a solar array on the roof and a deep energy retrofit is also in the cards including shading, natural cooling and efficient user controlled heating. Many proposals for net zero energy buildings exist now but few retrofits go so far, especially retrofits that improve the environment rather than just degrading it at a slower pace.
