What is BS EN 16798-17- Ventilation for buildings about?
BS EN 16798-17 is the 17th part of the multi-series European Standard that specifies the common methodology and the requirements for inspection of air conditioning systems in buildings for space cooling and/or heating and/or ventilation systems from an energy use standpoint. It can be used to fulfil the EPBD requirements (Energy Performance of Buildings Directive 2010/31/EU [9]) as well as in other contexts where such inspections are specified. The methodology specified in BS EN 16798-17 deals with indoor climate problems that can be due to the systems inspected.
BS EN 16798-17 applies to both residential and non-residential buildings equipped with:
- Air conditioning system(s) without mechanical ventilation
- Air conditioning system(s) with mechanical ventilation
- Natural and mechanical ventilation system(s)
Note-
The inspection of systems includes but is not limited to the following components:
- Reverse-cycle operation of air-conditioning equipment
- Associated water and air distribution and exhaust systems that form a necessary part of the system
- Controls that are intended to regulate the use of associated water and air distribution and exhaust system
BS EN 16798-17 is not applicable to:
- Qualification of the persons or organization in charge of inspections
- Frequency of the mandatory inspection (defined at the national level)
- Components supporting the heating function (specified in EN 15378-1:2017 [8] and the accompanying technical report CEN/TR 15378-2:2017 [8] covering the inspection of heating only systems using boilers)
Who is BS EN 16798-17 - Ventilation for buildings for?
BS EN 16798-17 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 16798-17 - Ventilation for buildings?
Air conditioning systems differ among the member countries due to climate, traditions and national regulations. In some cases, requirements are given as levels so national or individual needs can be accommodated. So, the Member States are free to choose between different objects and the extent of inspection, within a harmonized framework.
BS EN 16798-17 deals with the following points that will help you to:
- To establish a regular inspection of the accessible parts of air-conditioning systems of an effective rated output of more than 12 kW
- Assess the air-conditioning efficiency and the sizing compared to the cooling requirements of the building
- Replacement of air-conditioning systems or on other modifications to the air-conditioning system
- Inspection of ventilation systems, and of the associated air distribution and exhaust systems taking into account general indoor climate conditions, in order to avoid negative effects such as inadequate ventilation
What’s changed since the last update?
BS EN 16798-17:2017 supersedes BS EN 15240:2007 and BS EN 15239:2007, which are withdrawn.
In addition to a number of editorial revisions, the following main changes have been made with respect to EN 15239:2007 and EN 15240:2007 which were developed during the first EPBD mandate [9]:
- Formatting in accordance with the new rules set in CEN/TS 16629 [6], this includes the transfer of all informative points in the associated technical report CEN/TR 16798-18
- Merger between the previous standards (EN 15239:2007 and EN 15240:2007) dealing with the inspection of ventilation and air conditioning systems into a single document. The general aspects of the inspection that concern both ventilation and air conditioning systems are covered in Clause 5. This includes the description of the pre-inspection procedure prior to the on-site visit
- Clarification of the outputs of each inspection phase (pre-inspection, on-site inspection methodology, report). Clause 8 includes checklists of items to be included in the inspection report
- Introduction of three inspection levels (level 1, level 2 and level 3) taking into consideration the results of the Concerted Action, lessons from research projects and practical applications. The less demanding level (level 1) does not require measurements and is sufficient to comply with the requirements of the EPBD recast [9]
- Clarification of the inspection of air filters (6.4.2.4)
- Emphasis on advice for improvement to be included in the report (including economic justification)
