Standardization in the field of building and civil engineering works

  • of thermal and hygrothermal performance of materials, products, components, elements and systems, including complete buildings, both new and existing, and their interaction with technical building systems;
  • of thermal insulation materials, products and systems for building and industrial application, including insulation of installed equipment in buildings;

covering and including:

  • test and calculation methods for heat and moisture transfer, temperature and moisture conditions;
  • test and calculation methods for energy use in buildings, including the industrial built environment;
  • test and calculation methods for heating and cooling loads in buildings;
  • test and calculation methods for daylighting, ventilation and air infiltration;
  • in-situ test methods for thermal, hygrothermal and energy performance of buildings and building components, input data for calculations, including climatic data;
  • specifications for thermal insulation materials, products and systems with related test methods and conformity criteria;
  • terminology; and
  • general review and coordination of work on thermal and hygrothermal performance within ISO.


  • building environment design (ISO/TC 205);
  • methods of testing and rating the performance of building environmental equipment for application in the design of new buildings and retrofits (ISO/ TC 205); and
  • design methods and criteria for daylighting, ventilation and air infiltration (ISO/TC 205)

Covering also:

Standardization of the holistic assessment of the energy performance of new and existing buildings as well as building retrofits, in close collaboration with ISO/TC 205 by means of the ISO/TC163/WG4 Joint working group TC 163 & TC 205 Energy performance using holistic approach, including:

  • terms and definitions;
  • system boundaries for buildings and technical systems;
  • assessment of the overall energy performance of buildings, taking into account
    • the energy performance of building elements;
    • building related systems (heating, cooling, domestic hot water, ventilation, lighting, system controls, transport, and other energy related systems);
    • indoor and outdoor conditions;
    • local energy production (on site and at district level);
    • (use of) energy sources (including renewable);
    • building commissioning;
    • assessment of overall energy efficiency; and
    • means of expressing the energy performance and energy performance certification of buildings.
