Scope

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.

Excluded:

• 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.
