BS EN 16798-3:2017

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BS EN 16798-3:2017 supersedes BS EN 13779:2007, which is withdrawn.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
