20、ber bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmen

21、tal and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Direct

22、ives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies

25、capacity Part 3: Design and dimensioning Part 4: Dimensioning and calculation of the dynamic heating and cooling capacity of Thermo Active Building Systems (TABS) Part 5: Installation Part 6: ControlPart 1 of this International Standard defines the comfort criteria which should be considered in desi

26、gning embedded radiant heating and cooling systems, since the main objective of the radiant heating and cooling system is to satisfy thermal comfort of the occupants. In Part 2, steady-state calculation methods for determination of the heating and cooling capacity are provided. Part 3 specifies the

27、design and dimensioning method of radiant heating and cooling systems to ensure the heating and cooling capacity. Part 4 provides a dimensioning and calculation method to design Thermo Active Building Systems (TABS) for energy-saving, since radiant heating and cooling systems can reduce energy consu

28、mption and heat source size by using renewable energy. Part 5 describes the installation process for the system to operate as intended. Finally, Part 6 describes a proper control method for the radiant heating and cooling systems to ensure the maximum performance which was intended in the design sta

29、ge when the system is actually being operated in a building.1) Parts 1, 2, 3, 4 and 6 are to be published.iv ISO 2012 All rights reservedBS EN ISO 11855-5:2015INTERNATIONAL STANDARD ISO 11855-5:2012(E)Building environment design Design, dimensioning, installation and control of embedded radiant heat

30、ing and cooling systems Part 5: Installation1 ScopeThis part of ISO 11855 establishes guidelines on the installation of embedded radiant heating and cooling systems. It specifies uniform requirements for the design and construction of heating and cooling floors, ceiling and wall structures to ensure

31、 that the heating/cooling systems are suited to the particular application. The requirements specified by this part of ISO 11855 are applicable only to the components of the heating/cooling systems and the elements which are part of the heating/cooling surface and which are installed due to the heat

32、ing/cooling systems.This part of ISO 11855 is applicable to water-based embedded surface heating and cooling systems in residential, commercial and industrial buildings. The methods apply to systems integrated into the wall, floor or ceiling construction without any open-air gaps, but are not applic

33、able to panel systems with open-air gaps which are not integrated into the building structure.2 Normative referencesThe following referenced documents are indispensable for the application of this document.
