Opening later this year, the Ragon Institute of MGH, MIT and Harvard in Cambridge, MA is an essay in the tuning of building façades for performance. The aluminum sunshades that veil the building began as a concept tested by scoring Bristol paper. The team utilized tools from all modalities: paper models, CNC-mills, parametric studies, solar analysis, wind and water simulations and full-scale mock-ups to inform the design and drive energy use down. The ultra-high performance building is tracking a 61% reduction in energy use compared to the 2030 baseline.
