ZAG is developing monitoring of building environment, including buildings, engineering structures and infrastructure. Monitoring was included in a number of national and EU research projects with ZAG being coordinator or partner (eg. SPENS, ARCHES, SMART RAIL, SENSE, TRIMM, COST EFFECTIVE). A huge amount of data from these activities were used by a limited number of endusers for detailed analysis of particular building environment, but could also be used by any other entity for development of innovative applications supporting safe, adaptable, automated, comfortable, resilient, etc. smart cities. ZAG will support interested entities with comprehensive expert knowledge from the field of civil engineering, will continuously contribute data from existing monitoring systems and will also create new ones.
