Optically transparent, thermally insulating and soundproofing (OTTIS) aerogel for high-efficiency window applications
Building heating, ventilation and air conditioning (HVAC) accounts for about 13.6 quadrillion BTU ("quads") per year or 14% of the total energy consumption in the United States.' Accounting for 39% of annual US carbon dioxide emissions, this consumption is directly related to the energy efficiency …
