BS EN 16798-9 is the ninth part of the multi-series standard that defines energy performance indicators for cooling systems.
BS EN 16798-9 covers the energy performance calculation of complete cooling systems. It gives a calculation method that defines how to collect the cooling energy requirements from the thermal zones and from the air handling units connected to a distribution system, and how to aggregate multiple distribution systems to an overall system energy requirement.
It incorporates the calculation of the emission and distribution losses and auxiliary energy. The required cooling energy to be extracted by the cooling generation system is calculated, and the cooling energy storage is considered. It gives a method on how to dispatch the cooling energy provided by the cooling generation to different distribution systems, and priorities are considered.
BS EN 16798-9 on ventilation for buildings is useful for:
BS EN 16798-9 aims at international harmonization of he the methodology for the assessment of the energy performance of buildings, called EPB set of standards which follow specific rules helpful for installers, engineers, regulators, programmers to ensure overall consistency, unambiguity, and transparency.
BS EN 16798-9 aids EPB standards to provide certain flexibility about the methods, the required input data, and references to other EPB standards
BS EN 16798-9 helps the installer to apply and combine the calculation methods given in the different cooling-related standards covering sub-system calculations, to get a consistent overall calculation of an envisaged cooling system. Also, to express the energy performance of cooling systems as a technical system-related energy performance indicator.
Different modules specified in BS EN 16798-9 help the producer to examine an overview of the relation to modules, boundaries, and involved indices and help the user to apply the EPB standard to assess the energy performance of a building and thereby using the choices made by the regulators.
BS EN 16798-9:2017 supersedes EN 15243:2007 which is withdrawn
EN 15243:2007 was produced to meet the requirements of Directive 2002/91/EC 16 December 2002 on the energy performance of buildings referred to as “EPBD”.
