Energy performance of buildings - Ventilation for buildings - Part 5-2: Calculation methods for energy requirements of ventilation systems (Modules M5-6, M5-8, M6-5, M6-8, M7-5, M7-8) - Method 2: Distribution and generation
SIST EN 16798-5-2:2018

This European Standard covers energy performance calculation of mechanical ventilation systems with integrated heating/cooling generation, including domestic hot water production, using a monthly or seasonal calculation interval or a bin method. It takes into account the generation (air handling unit) and distribution (duct system) parts. It does not cover the emission part (calculation of the required volume flow rates and/or supply air conditions), which is covered in the M5-5 standard. It does not include humidification and dehumidification. This method is focussed on small, packaged ventilation systems, typically used in residential buildings, although the application is not restricted on the basis of building or space use type.
A calculation method for mechanical ventilation and air conditioning systems, including humidification and dehumidification, using an hourly calculation interval or a bin method, is provided in a separate standard, EN 16798 5 1.
Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000 1.
NOTE 1   In CEN ISO/TR 52000 2, the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation.
NOTE 2   The modules represent EPB standards, although one EPB standard might cover more than one module and one module might be covered by more than one EPB standard, for instance a simplified and a detailed method respectively. See also Clause 2 and Tables A.1 and B.1.

Energy performance of buildings - Ventilation for buildings - Part 3: For non-residential buildings - Performance requirements for ventilation and room-conditioning systems (Modules M5-1, M5-4)
SIST EN 16798-3:2018

This European Standard applies to the design, energy performance of buildings and implementation of ventilation, air conditioning and room conditioning systems for non-residential buildings subject to human occupancy, excluding applications like industrial processes. It focuses on the definitions of the various parameters that are relevant for such systems.
The guidance for design given in this European Standard and accompanying FprCEN/TR 16798-4 are mainly applicable to mechanical supply and/or exhaust ventilation systems. Natural ventilation systems or natural parts of hybrid ventilation systems are not covered by this European Standard. Reference is made to the Technical Report for informative guidance on the design of such systems.
Applications for residential ventilation are not dealt with in this European Standard. Performance of ventilation systems in residential buildings are dealt with in EN 15665 and CEN/TR 14788.
The classification uses different categories. For some values, examples are given and, for requirements, typical ranges with default values are presented. The default values given in this European Standard are not normative as such, and should be used where no other values are specified. Classification should always be appropriate to the type of building and its intended use, and the basis of the classification should be explained if the examples given in the European Standard are not to be used.
NOTE 1   Different standards may express the categories for the same parameters in a different way, and also the category symbols may be different.
Table 1 shows the relative position of this European Standard within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000 1 .
NOTE 2   In FprCEN ISO/TR 52000 2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation.
NOTE 3   The modules represent EPB standards, although one EPB standard may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively. See also Clause 2 and Tables A.1 and B.1.

Energy performance of buildings - Ventilation for buildings - Part 13: Calculation of cooling systems (Module M4-8) - Generation
SIST EN 16798-13:2018

This European Standard covers the calculation of the operational parameters and the energy consumption of cooling generation systems. The cooling generation consists of:
-   cooling generators like compression and absorption chillers;
-   other (generic) generator types such as ground or surface water or direct use of ground heat from boreholes; and
-   different types of heat rejection (dry, wet, hybrid with outdoor air, other sink types).
The methods cover:
-   the possibility of heat recovery of heat to be rejected for the use of heating and/or domestic hot water production, through the use of an interface to the M3-1 standard; and
-   a multi generator calculation.
The document does not cover the cooling emission, distribution and storage systems, which are covered by the Module M4-5, M4-6 and M4-7 standards, respectively. It is directly connected to the general part of the cooling systems, the M4-1 standard.
Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in prEN ISO 52000 1:2015.

Energy performance of buildings - Ventilation for buildings - Part 9: Calculation methods for energy requirements of cooling systems (Modules M4-1, M4-4, M4-9) - General
SIST EN 16798-9:2018

This European Standard 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 possible priorities are considered.
This European Standard defines energy performance indicators for cooling systems.

Energy performance of buildings - Ventilation for buildings - Part 7: Calculation methods for the determination of air flow rates in buildings including infiltration (Modules M5-5)
SIST EN 16798-7:2018

This European Standard describes the methods to calculate the ventilation air flow rates for buildings
to be used for energy calculations evaluation, heating and cooling loads.
This European Standard applies to buildings with:
-   Mechanical ventilation systems (mechanical exhaust, mechanical supply or balanced system);
-   Passive duct ventilation systems for residential and low-rise non-residential buildings;
-   Combustion appliances;
-   Windows opening by manual operation;
-   Kitchens where cooking is for immediate use (including restaurants)
This European Standard is applicable to hybrid systems combining mechanical and passive duct ventilation systems in residential and low-rise non-residential buildings.
This European Standard applies to buildings smaller than 100 m and rooms where vertical air temperature difference is smaller than 15 K.
The results provided by the standard are:
   the air flow rates entering or leaving a ventilation zone;
-   the air flow rates required to be distributed by the mechanical ventilation system, if present.
This European Standard is not applicable to:
-   Buildings with kitchens where cooking is not for immediate use
-   Buildings with automatic windows (or openings)
-   Buildings with industry process ventilation.
The definition of ventilation and airtightness requirements (as indoor air quality, heating and cooling, safety, fire protection…) is not covered by this standard.
The following information can be found in other standards and technical reports:
-   guidance to estimate pressure drops in ducts (CR 14378:2002)
