Introduction
The set of EPB standards, Technical Reports and supporting tools
In order to facilitate the necessary overall consistency and coherence, in terminology, approach,
input/output relations and formats, for the whole set of EPB-standards, the following documents and
tools are available:
a) a document with basic principles to be followed in drafting EPB-standards:
CEN/TS 16628:2014, Energy Performance of Buildings - Basic Principles for the set of EPB
standards [1];
b) a document with detailed technical rules to be followed in drafting EPB-standards;
CEN/TS 16629:2014, Energy Performance of Buildings - Detailed Technical Rules for the set of
EPB-standards [2]; and
c) the detailed technical rules are the basis for the following tools:
1) a common template for each EPB-standard, including specific drafting instructions for the
relevant clauses,
2) a common template for each technical report that accompanies an EPB standard or a cluster of
EPB standards, including specific drafting instructions for the relevant clauses, and
3) a common template for the spreadsheet that accompanies each EPB standard, to demonstrate
the correctness of the EPB calculation procedures.
Each EPB-standards follows the basic principles and the detailed technical rules and relates to the
overarching EPB-standard, EN ISO 52000-1:2017 [3].
One of the main purposes of the revision of the EPB-standards is to enable that laws and regulations
directly refer to the EPB-standards and make compliance with them compulsory. This requires that the
set of EPB-standards consists of a systematic, clear, comprehensive and unambiguous set of energy
performance procedures. The number of options provided is kept as low as possible, taking into
account national and regional differences in climate, culture and building tradition, policy and legal
frameworks (subsidiarity principle). For each option, an informative default option is provided
(Annex B).
Rationale behind the EPB technical reports
There is a risk that the purpose and limitations of the EPB standards will be misunderstood, unless the
background and context to their contents – and the thinking behind them – is explained in some detail
to readers of the standards. Consequently, various types of informative contents are recorded and made
available for users to properly understand, apply and nationally or regionally implement the EPB
standards.
If this explanation would have been attempted in the standards themselves, the result is likely to be
confusing and cumbersome, especially if the standards are implemented or referenced in national or
regional building codes.
Therefore, each EPB standard is accompanied by an informative technical report, like this one, where all
informative content is collected, to ensure a clear separation between normative and informative
contents (see CEN/TS 16629 [2]):
— to avoid flooding and confusing the actual normative part with informative content,
— to reduce the page count of the actual standard, and
— to facilitate understanding of the set of EPB standards.
This was also one of the main recommendations from the European CENSE project [4] that laid the
foundation for the preparation of the set of EPB standards.
This Technical Report
This Technical Report accompanies and complements EN 16798-17:2017 by providing informative
explanations and guidance to support the application of the normative content of the standard, taking
into account the requirements and options of the Recast Energy Performance of Buildings Directive [11]
(abbreviated as EPBD).
Air conditioning inspection may be carried out at any time and for a variety of purposes. It may, for
example, be part of a routine maintenance programme, though this may not include every part of the
guidance in the standard or technical report. Experience shows that inspections typically identify
measures that can result in tangible energy and running cost savings that require little or no capital
expenditure. However, these measures represent only a small proportion of the savings that are
technically possible. Inspections can also confirm that some potential sources of energy wastage are not
actually present.
The focus of the EPBD inspection requirements is to prevent energy wastage. However, measures to
reduce energy consumption should not be at the expense of the indoor environment, in particular
indoor air quality.
The specific requirements of the EPBD given in the corresponding article are the following:
— Article 15 requires the introduction of “measures to establish a regular inspection of the accessible
parts of air-conditioning systems of an effective rated output of more than 12 kW. The inspection
shall include an assessment of the air-conditioning efficiency and the sizing compared to the
cooling requirements of the building.”
— Article 16 requires that “an inspection report should be issued and handed to the owner or tenant
of the building after each inspection of a heating or air-conditioning system”. The inspection report
should contain the result of the inspection performed in accordance with Article 14 or Article 15
and include recommendations for the cost-effective improvement of the energy performance of the
inspected system. These measures should take into account climatic and local conditions as well as
indoor climate environment and should not affect other requirements concerning buildings such as
accessibility, safety and the intended use of the building.
— The recommendations may be based on a comparison of the energy performance of the system
inspected with that of the best available feasible system and a system of similar type for which all
relevant components achieve the level of energy performance required by the applicable
legislation.
— Alternatively, Member States “may opt to take measures to ensure the provision of advice to users
on the replacement of air-conditioning systems or on other modifications to the air-conditioning
system which may include inspections to assess the efficiency and appropriate size of the air-
conditioning system.”

5 Description of the inspection procedures
5.1 Purpose of the inspection
EN 16798-17:2017 requires that the recommendations include an indication of their probable cost-
effectiveness.
These recommendations are meant to encourage the system owner to undertake actions but they do
not require action from the owner.
To increase the likelihood that the proposed improvements are implemented, the inspection report
should stress improvements that are obviously needed to allow the system to function well and that are
cost-effective over a relatively short time period.
Detailed cost-effectiveness studies are outside the scope of EN 16798-17:2017. However, the advice can
include recommendations for detailed costs analyses, in particular, when an opportunity for
improvement is not obvious as a result of the inspection.
5.2 Methods
5.2.1 Features affecting the frequency and duration of inspection
5.2.1.1 General
The minimum contents and frequency of mandatory inspection is defined on national level, with a
recommended default value of five years for ventilation and air-conditioning systems. Inspection
including the buildings is recommended every ten years. On voluntary basis, more extensive and more
frequent inspections are possible.
The inspection may be more or less frequent, depending on the following:
— type of building;
— energy impact of the system;
— type of equipment;
— quality of system documentation;
— availability of records of measurements and/or energy check consumption metering; and
— quality of maintenance.
For centralized systems for cooling and ventilation, different parts and system components may require
more frequent checks, and in this case the corresponding records should be available for inspection.
After the initial inspection, the time for the next inspection may be longer or shorter depending on the
results from the initial inspection and on the level of maintenance.
The outcome of the inspection is to generate advice for the owner or manager to improve the system, or
improve system maintenance. A part of that advice is to recommend more frequent routine inspection
and maintenance, for a good practice maintenance programme. The advice should be integrated and
balanced with other energy conservation recommendations.
The time taken for the inspection obviously depends on the following parameters:
— size and age of the system;
— type of building;
— time since latest inspection;
— quality of documentation; and
— maintenance of the systems installed.
5.2.1.2 Ventilation-only systems
The health aspects might influence the energy performance of mechanically ventilated supply; therefore
inspection should focus on maintenance periods for:
— air filters;
— heat exchangers;
— sensors/controls where they are used.
For filters, heat exchangers and sensors/controls, a certification or a technical agreement should give an
advice on the maintenance period.
The frequency of the ventilation inspection depends on the system and its susceptibility to drift, fouling
and ageing. It might also depend on quality of maintenance.
A simple natural ventilation system is normally very robust in terms of ageing and fouling (large
apertures, simple grilles, no moving part) nevertheless; it is very sensitive to any change in the design
(some grilles may be tapped for instance, or the window changed) or to improved air tightness.
Conversely, an exhaust and supply with heat recovery system is susceptible to fouling and ageing but
less to any change of the building (provided the changes improve the air tightness which is the general
case). The system components are not as critical when changed due to the improved thermal comfort
they provide.
Some systems may provide self-detection of faults or issue a diagnostic warning, in which case a
monthly or annual report should be taken into account in determining the actual inspection frequency.
The influence of parameters on system components hence on inspection frequency is given in Table 1.

5.2.1.3 Air-conditioning systems
This technical report gives recommendation for:
— defining system categories, see 5.2.2;
— the extent of the inspection for ventilation-only systems, see 5.2.3.1; and
— the extent of the inspection for air conditioning systems, see 5.2.3.2.
The checklist given in 7.4 is suitable for a relatively “simple” inspection for a combined system.
However, this inspection does not provide a complete picture of the system energy performance
including the performance of controls.
5.2.2 Examples of elements to define system categories
5.2.2.1 Ventilation-only systems
The criteria that can be used to define the categories include the following:
— type of ventilation system: mechanical exhaust/supply, mechanical exhaust and supply, natural,
hybrid;
— nominal air flow rate;
— date of installation; and
— age of the building.
5.2.2.2 Air-conditioning systems
The criteria that can be used to define the categories include but are not limited the following:
— type of the air conditioning system (generation and emission);
— cooling capacity;
— annual running time;
— age of the installation;
— use of the building (e.g. residential, office, etc.); and
— location of the system (e.g. outdoor/indoor) and the building.
Table 2 gives an example on how to classify the system category.
