(Main)Ventilation for buildings - Performance measurement and checks for residential ventilation systems
General Information
- Abstract
This document specifies checks and measurement methods in order to verify the fitness for purpose of installed ventilation systems in dwellings. It can be applied to commissioning of new systems and performance testing of existing systems. It provides choice between simple test methods, when sufficient, and extensive measurements, when necessary.
Considering that this document has been developed for large scale application and considering the practical conditions of field measurements, no correction regarding ambient conditions (temperature and barometric pressure) is applied to functional measurements.
This document deals with items d), e), f), and g) of the following list giving the different stages of the design, installation, checking and measuring of a ventilation system:
a) design and dimensioning of residential system;
b) installation of system;
c) balancing and adjustment of system;
d) pre-checks on system;
e) functional checks on system;
f) functional measurements on system;
g) special measurements on system if required.
This document applies to ventilation systems (mechanical, hybrid, natural) comprising any of the following elements:
- air terminal devices (supply, extract, intake and exhaust);
- air transfer devices (externally mounted, internally mounted);
- controls;
- ducts;
- fans;
- filters;
- heat recovery;
- heating/cooling of supply air;
- recirculation air;
- cooker hood;
- cowls;
- dampers;
- sound reduction devices.
In case of multi-functional units, the checking and measuring only apply to the ventilation part. Therefore, this document does not apply to:
- heating systems and their control;
- refrigerating systems and their control;
- electrical power supply systems.
It does not cover the following points:
- airtightness of the building envelope; the whole dwelling and the individual room ventilation rates can be influenced by air infiltration through the building envelope (see EN ISO 9972);
- effect of the ventilation system on indoor air speed within the occupied zone (see for example EN 15726).

Overview
EN 14134:2019 - "Ventilation for buildings - Performance measurement and checks for residential ventilation systems" (CEN) defines practical on‑site checks and measurement methods to verify the fitness‑for‑purpose of installed residential ventilation systems. Intended for large‑scale field use, it supports commissioning of new systems and performance testing of existing systems across mechanical, hybrid and natural ventilation installations. The standard emphasizes practical, scalable procedures (simple tests where sufficient, more extensive measurements when necessary) and specifies that no correction for ambient conditions (temperature, barometric pressure) is applied to functional measurements.
Key Topics
- Scope and applicability: Covers the ventilation part of systems including air terminal devices, ducts, fans, filters, heat recovery, controls, dampers, sound reduction, cooker hoods and recirculation air. Excludes heating, refrigeration and electrical power supply systems.
- Stages addressed: Focuses on stages d–g of the lifecycle - pre‑checks, functional checks, functional measurements, and special measurements - rather than design, installation or balancing.
- Measurement procedures: Describes on‑site methods for air flow rate and direction, static pressure, running time, and specialized tests (ductwork leakage, sound pressure level, electrical power).
- Sampling and scalability: Provides sampling strategies suitable for large‑scale application and field conditions, allowing selection between simple and extensive methods.
- Practical constraints: No ambient corrections applied; requirements account for field measurement conditions and equipment uncertainty. Includes checklists and reporting templates to standardize results.
- Reporting: Specifies content for test reports including pre‑check documentation, functional checklists, measurement results and any special measurement outcomes.
Applications
- Commissioning and acceptance testing of residential ventilation systems.
- Performance verification during maintenance, retrofits, or building handover.
- Quality assurance for HVAC contractors, test‑and‑balance technicians and commissioning agents.
- Compliance checks by building inspectors, facility managers and social housing authorities.
- Product/installation verification for manufacturers and installers of multi‑functional units (ventilation portion only).
Who should use it
- HVAC engineers and designers
- Commissioning and testing professionals
- Installers and maintenance teams
- Building owners, facility managers and regulators
- Manufacturers of ventilation equipment
Related Standards
- EN ISO 9972 (building airtightness / blower door)
- EN 15726 (indoor air speed considerations)
- EN 1507, EN 12237 (ductwork strength and leakage)
- EN 12792 (terminology and symbols)
- EN ISO 16032 (sound pressure measurement from service equipment)
EN 14134:2019 is a practical, field‑oriented standard for ensuring residential ventilation systems perform as intended - useful for anyone responsible for commissioning, testing or maintaining healthy, efficient ventilation in dwellings.
