What is BS EN 16798-3 - Ventilation for buildings about?
BS EN 16798-3 is the third part of the European Standard that 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.
Note-
Natural ventilation systems or natural parts of hybrid ventilation systems are not covered by BS EN 16798-3.
Applications for residential ventilation are not dealt with in BS EN 16798-3.
Performance of ventilation systems in residential buildings are dealt with in EN 15665 and CEN/TR 14788.
Who is BS EN 16798-3 - Ventilation for buildings for?
BS EN 16798-3 on ventilation for buildings is useful for:
- Regulators of EPB standards  
- Manufacturer, designers, installers, of cooling systems  
- Construction industry  
- Civil engineer
- Architects
Why should you use BS EN 16798-3 - Ventilation for buildings?
BS EN 16798-3 illustrate guidance for the design and accompanying CEN/TR 16798-4 mainly applicable to the mechanical supply and/or exhaust ventilation systems. Reference is made to the Technical Report for informative guidance on the design of such systems.
BS EN 16798-3 focuses on the system aspects for typical applications and cover the following:
- Aspects important to achieve and maintain a good energy performance in the systems without any negative impact on the quality of the indoor environment.
- To design and performances data.
This will help you to achieve a comfortable and healthy indoor environment in all seasons with acceptable installation and running costs.
What’s changed since the last update?
BS EN 16798-3:2017 supersedes BS EN 13779:2007, which is withdrawn.
The revision concerns mainly the following aspects:
- New structure to clarify designing and calculation aspects
- Update of filtration aspects
- Update of heat recovery aspects and leakages in these systems
- Clear coordination with prEN 16798-1:2015, outdoor air volume flows have been shifted to prEN 16798-1:2015
- All indoor air quality aspects have been deleted; supply air quality have been introduced
- Aspects of energy performance have been updated
- Update of definitions of systems
- Update of SPF definitions and links to EU 327/2014 regulation
- The document was split into a normative part, containing all the normative aspects and a supplementary technical report containing additional information and informative annexes
- The standard allows a normative national annex
- The standard was updated to cover hourly/monthly/seasonal time-step
