          The EU Building Energy Performance Directive
          sets new norms that are hard to meet without
          making buildings smart. Smart buildings require
          smart  engineering  systems  able  to  adjust to
          buildings’ needs. HVAC accounts for about 40%
          of the total energy use in most buildings. Making
          HVAC systems more efficient can bring substan-
          tial improvements in the overall building’s energy

          The smart building concept implies a set of
          communication technologies enabling objects
          within a building to communicate and interact
          with each other and be managed, controlled and
          automated remotely. A study by the American                                                     © ABB
          Council finds cost savings of 24 – 32% when
          using smart HVAC and smart lighting. So, it
          does make sense to consider the “smartness” of
          components for successful smart HVAC system
