Ventilation for buildings - Performance measurement and checks for residential ventilation systems

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).

Introduction

The purpose of a residential ventilation system is to supply air to and extract air from rooms in a dwelling.

The ventilation system should be designed to achieve the purpose whilst minimizing energy use and

possible discomfort (e.g. noise, draught).

The performance requirements of the ventilation system are laid down by the designer in the dwelling

specifications.

1 Scope

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;

— heat recovery;
— heating/cooling of supply air;
— recirculation air;
— cooker hood;
— cowls;

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).

5 Check and measurement procedures
5.1 General
This document includes procedures for:
— pre-check;
— functional checks;
---------------------- Page: 11 ----------------------
SIST EN 14134:2019
EN 14134:2019 (E)
— functional measurements;
— special measurements.

Checks and measurements to be performed shall be defined beforehand to meet the needs.

The installation work should be completed and the system should be adjusted before starting checks and

measurements.

Safe access to the ventilation system is required for on-site checks and measurement.

5.2 Checks and measurements conditions
Checks and measurements conditions are as follows:
— the mechanical ventilation system shall be switched on;
— the system settings shall remain unchanged during measurements;
— all external and internal doors, and windows shall be closed;

— all other ventilation provisions such as externally and internally mounted air transfer devices should

be set in their intended position which shall be recorded in the report;

— as set points of control devices have an impact on the performances of the system, they shall be

recorded in the report.

— in the case of occupancy control or demand control and as the value of the relevant parameters has

an impact on the performances of the system, these parameters or any overriding of the controls

should be recorded in the report.
5.3 Sampling

Checks and measurements for ventilation systems of the same type (example of types are natural

ventilation, unidirectional ventilation or bidirectional ventilation) within apartments belonging to the

same building or within houses belonging to the same housing estate can be performed on a sample of

these apartments or houses.

NOTE The basic assumption behind the authorization for sampling is that ventilation systems that belong to

such groups (same type and same building or same housing estate) and that are considered together for the purpose

of measurement and checks (for example because of same owner or same general contractor or same installer) have

enough similarities to make sampling relevant.

The sample size depends on the selected sampling level and the total number of apartments or houses of

the considered group. Table 2 gives the sampling error for each sampling level for a level of confidence

of 95 %. Table 3 gives the sample size as a function of the total number of apartments or houses for each

sampling level. For total numbers of apartments or houses that are not in Table 3, the sample size is

calculated using Formula (1).

NOTE Details of the formula can be found in “Theory and problems of statistics” (confidence intervals for

proportions) by M.R. Spiegel edited by Schaum's Outlines (ISBN 0-07-060281–6).

By default, the sampling level is SL1. Different sampling levels may be selected for different types of

checks or measurements. Checks or measurements at the same sampling level shall be carried out within

the same sample.

EXAMPLE 1 Sampling level SL3 is chosen for flow measurements and pressure measurements. In this case these

two types of measurement are performed on the same sample.
Smaller samples shall only include apartments or houses from larger samples.

EXAMPLE 2 Sampling level SL3 is chosen for flow measurements and sampling level SL4 is chosen for acoustic

measurements. In this case the sample for acoustic measurements is chosen within the sample for flow

measurements.

Sampling is not applicable for checks and measurements within a single house or apartment.

EXAMPLE 3 An apartment with 10 air terminal devices is part of a sample for flow measurements. In this case,

all 10 air terminal devices are measured whatever the sampling level.

6 Pre-check
6.1 General

The aim of the pre-check is to collate and assess all relevant documentation relating to the building and

the installed ventilation systems with particular regard to:
— design parameters, system characteristics and settings; and
— operation, maintenance and use.
6.2 Documents for design parameters, system characteristics and settings
The following documents shall be collated:
— general building drawings with the positions and the functions of all rooms;
— ventilation system design specification;
— fiche with product technical data.

It shall be checked that the design specification contains the following elements:

— type of ventilation system (e.g. central or decentral, natural, fan assisted natural, mechanical

supply/exhaust/balanced or a combination of these);
— air flow control strategy (central, zonal or room based);
— type of controls (if any):
— manual control (the system runs according to a manually controlled switch);
— time control (the system runs staged according to a given time schedule);
— presence control (the system runs dependent on the presence of people);

— demand control (the system runs staged dependent on any indicator for the need of ventilation);

— location of the control devices;

— specification of the control devices (e.g. range and response of humidity sensor);

— design air flow rates for the ventilation system as a whole, for individual rooms and for individual air

terminals (or equivalent information for natural ventilation systems (e.g. duct sizes, equivalent areas

of air transfer devices));
— designed range of static pressure available at ATD;

— information on the different components of the ventilation system as given in Table 4.
