EN 15239:2007 – Ventilation for buildings – Energy performance of buildings – Guidelines for inspection of ventilation systems

1 Scope
This standard develops the methodology required for the inspection of mechanical and natural ventilation systems in relation to its energy consumption.
This standard applies to both residential and non residential buildings.
The inspection may include the following issues, in order to determine the energy performance of the building and its associated mechanical / electrical plant:
The system conformity related to the original and subsequent design modifications, actual requirements and the present building state.
Correct operation of the mechanical, electrical or pneumatic components.
Provision of an adequate and pure supply of ventilation air.
The functioning of all the controls involved.
Fan power absorbed and specific fan power.
Building air tightness.
It is not the intention of the standard to provide a full ventilation system audit. Its purpose is to assess
its functioning and its impact on energy consumption. It includes recommendations on possible system improvements.
NOTE The inspection, performed by an independent person to assess the system performance relating to energy consumption, is different from the maintenance that is performed to the owner’s requirements to maintain the optimum system performance.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 12792:2003 and the following apply.
3.1
centralised ventilation
ventilation of a space or spaces within a building by means of supply ductwork, extract ductwork or a combination of both, from a centralized plant room
3.2
inspection
inspection, in the manner of this standard means to examine the ventilation systems in buildings
3.3
local ventilation
ventilation of a set area of a space by means of supply ductwork, extract ductwork or a combination of both
NOTE Local ventilation can also be achieved by means of natural wall or roof inlets or outlets or by mechanical means by a fan or fans in the perimeter wall, internal wall, or roof.
3.4
assumptions
set of descriptions to be considered by the person in charge of the inspection, if the actual requirements are difficult to identify in the analysis
3.5
building system control
measures taken in ensuring the system operates in accordance with the specified conditions
3.6
commissioning
sequence of events necessary to ensure the building and its associated heating, ventilation and air conditioning systems are functioning in accordance with the design parameters
3.7
design criteria
set of descriptions based on a particular environmental element such as indoor air quality, thermal,acoustical, and visual comfort, energy efficiency and the associated system controls to be used for assessing the plant operation
3.8
control parameters
set values of the internal environmental conditions related to the external conditions
3.9
design documentation
written description of the essential design elements of the plant
3.10
self regulating valve
terminal component (for example: self adjustable air transfer device) or aerodynamic ductwork (for example: regulator of flow rate) allowing to insure a constant flow rate on a pressure operating range in
NOTE Some valves are designed with two flow rates (a nominal flow rate and a reduced nominal flow rate).
