ISO/TC 163

Thermal performance and energy use in the built environment

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; andgeneral 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); anddesign 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 accountthe 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; andmeans of expressing the energy performance and energy performance certification of buildings.
