Decarbonizing Europe by 2050 requires in-depth renovations of existing buildings to reduce their energy needs. High quality refurbishment processes (design, construction and maintenance) must narrow down the to-day’s building measured energy performance gaps between what is foreseen by design and the real performance of refurbished buildings when used. BulldozAIR (http://www.bulldozair.com/
) is an innovative, low entry cost, easy-to-use software suite developed by BLOCKBASE, now commercially accessible under a SaaS (Software as a Service) purchase mode within the Apple, Microsoft and Google operating systems. From their existing French customer base, the project aims at validating the routes that BLOCKBASE must follow to open European and US markets for the BulldozAIR software suite serving the whole refurbishment value chain.
