Building automation and control systems - Part 7: BACS contribution on the energy efficiency of buildings prEN ISO 16484-7

Scope

This international Standard specifies:
– a structured list of control, building automation and technical building management functions which
contribute on the energy performance of buildings;
– a method to define minimum requirements regarding the control, building automation and technical
building management functions to be implemented in buildings of different complexities;
– factor based method to get a first estimation of the effect of these functions on typical buildings
– detailed methods to assess the effect of these functions on a given building. These methods enable to
introduce the contribution of these functions to the calculations of energy performance ratings and
indicators calculated by the relevant standards;
This international Standard is defined for:
– building owners, architects or engineers, defining the functions to be implemented for a given new building
or for the renovation of an existing building;
– public authorities, defining minimum requirements for BAC and TBM functions for new buildings as well as
for renovation as defined in the relevant standard;
– public authorities, defining inspection procedures of technical systems as well as inspectors applying
these procedures to check if the level of BAC and TBM functions implemented is appropriate;
– public authorities, defining calculation methods which take into account the effect of BAC and TBM
functions on the energy performance of buildings as well as software developers implementing these
calculation methods and designers using them;
– designers, checking that the effect of all BAC and TBM functions are taken into account when assessing
the energy performance of a building.
NOTE The terms BAC (Building Automation and Control) and BACS (Building Automation and Control System) are
equivalent in view of energy calculation and energy efficiency. In this case BACS will be used in the English version and
BAC (German term: "GA Gebäudeautomation") in the German version.
