Introduction
On 1 May 2001, the Benefeu project started with a consortium managed by Warrington Fire Research
(UK) composed of CTICM (activity transferred to Efectis France), DIFT, IST, RUG and TNO (activity
transferred to Efectis Nederland).
The programme was financed by the European Commission (EC contract EDT/01/503480).
With a duration of one year, the programme aimed to identify the potential benefit of Fire Safety
Engineering in the European Union.
The CEN TC127 WG8 dedicated to Fire Safety Engineering identified a need of updating the work
performed within the BENEFU programme as a benefit for European standardization work and European
member states.

1 Scope
This document gives an overview of the evolution of regulations and application of Fire Safety
Engineering (FSE) in Europe. Based on work performed in 2001-2002, a full update of information has
been done. A global survey based on questionnaires defined in 2001, the evolution and possible
perspectives of the FSE practices within two perimeters are presented:
• The first perimeter is the same perimeter analysed in 2001 corresponding to the European Union
defined in 2001 extended to European countries with European Union agreement (Switzerland,
Norwegian and Iceland).
• The second perimeter is the European Union perimeter of 2016 extended to European countries with
European Union agreement (Switzerland, Norwegian and Iceland).
Conclusions and initiatives of the 2001 proposals were analysed 15 years after, with and without the
extension of European Union. New initiatives have since been proposed.
In addition, the state-of-the-art of Fire Safety Engineering is updated.

4 The Benefeu programme
4.1 Organization and tasks
On 1 May 2001, the Benefeu project started with a consortium managed by Warrington Fire Research
(UK) composed of CTICM (activity transferred to Efectis France), DIFT, IST, RUG and TNO (activity
transferred to Efectis Nederland).
The programme was financed by the European Commission (EC contract EDT/01/503480).
With a duration of one year, the programme aimed to identify the potential benefit of Fire Safety
Engineering in the European Union.
To satisfy this aim, this programme was organized in three key tasks:
• Task A – Current regulations in member states;
• Task B – State of the art in FSE;
• Task C – Possible initiatives and cost benefit analysis.
The final report [1] dated 19 July 2012 was presented to the European Commission.

4.2 Task A – Current regulations in member states
In order to collect information from the 15 member states of the European Union plus three countries
that signed conventions (Switzerland, Norway and Iceland), a questionnaire [2] was prepared and
produced by the consortium.
It was sent to the regulators of the member states and to FSE users with responses collected by the
Consortium.
A global overview of the European Union situation from these 18 countries was drawn. The main topics
were:
• fire regulation;
• enforcement of regulations;
• societal goals;
• functional/performance requirements;
• technical details in regulations;
• alternative approval system or derogation;
• changes to regulation;
• no regulatory obligation;
• cost-benefit analysis;
• fire safety engineering;
• education and training in FSE; and
• other points
In addition, fire experts or regulators from non-European countries (New Zealand, Australia, USA, Brazil,
Singapore, Canada, Japan, and Hong Kong) completed the questionnaire.
The consortium concludes that “the distribution of the answers is generally very similar to the
distribution in Europe, but the following main differences are noticed:
• Within fire safety regulations, the goal of business and social activity protection is covered by 30 %
of the non-European countries, instead of about 10 % in Europe.
• Concerning the type of requirements, most of the non-European countries have prescriptive or
deemed to satisfy requirements, but not both as is observed in Europe.
• Concerning the knowledge of fire safety engineering use in the different subsystems, contrary to
Europe where most of the countries consider that SS2 (66 %), SS3 (90 %) and SS4 (70 %) need little
work or are mature, 50 % of non-European countries consider that they need much work.
4.3 Task B – State-of-the-art FSE
The state of art of FSE was a worldwide overview including development, standardization and
regulations.

---------------------- Page: 8 ----------------------
kSIST-TP FprCEN/TR 17524:2020
FprCEN/TR 17524:2020 (E)
The main conclusion from this state-of-the-art review performed in 2001-2002 was:
• need for performance-based code coordination to avoid barriers to services in Europe;
• huge progress on implementation tools was made from 1990, nevertheless “operational and
unambiguous standards” are needed to have a common way to assess the safety level;
• need for coordination of standardization and pre-standardization between the various committees;
• evolution of standard tests to represent the “real world” scenario; and
• development of training and education to satisfy the future needs of Fire Safety Engineers in Europe,
with a need to mobilise global awareness to support the process.
Next a list of research needs, input data and standardization were attributed to the different technical
and scientific topics, describing the level of knowledge.
4.4 Task C – Initiatives and cost-benefit analysis
• From the previous tasks A and B, the consortium listed five main initiatives:
• To create a network of fire regulators to steer concerted action towards the transition from
prescriptive codes to performance-based codes, allowing the application of fire safety engineering
techniques. This steering should coordinate work from the four following initiatives, verify the
implementation of that work and maintain the relationship with the European Commission and CEN.
• To create a harmonized framework within which performance-based codes can function and create
a model code. The framework objectives are to define the new EU policy for Fire Safety, introduce
the common use of FSEs, share between member states a common view of the development of
performance-based codes with regulatory convergence and so avoid the creation of new trade
barriers within the EU. The framework could be based on the following scheme (see Figure 1):

---------------------- Page: 9 ----------------------
kSIST-TP FprCEN/TR 17524:2020
FprCEN/TR 17524:2020 (E)


Figure 1 — Framework example
A ten-year plan was identified to reach a common framework (two years), a model code (one year)
and national performance-based codes (five years).
• To set up an advisory committee on research, which will list and prioritise the most urgent and
important research needs in support of performance-based regulations. To promote the allocation
of sufficient research funds to this subject, use should be made of the European Research Framework
programmes. This initiative for FSE was compared to the Reaction to Fire research programme that
led to new standardization and European harmonization from 1988 to 2000. A new ten-year plan
was proposed to include the development of research in standardization (identification two years,
execution six years, introduction in standardization two years)
• To develop a mandate for standardization, building on existing knowledge and the results of the
identified, targeted research. This initiative promotes the use of ISO TC 92 SC4 standardization work
to avoid duplication of work and identifies the need for standard tests to create extended application
data for the performance of construction products to use in FSE calculations. To perform that work,
the initiative identifies a need for a mandate for FSE development in CEN. A timing of three years was
given to identify standardization requirements and publish specific mandates.
• To undertake all necessary action to define the professional education needs and the conditions for
professional recognition. The objectives were the production of structured education and a structure
for professional recognition. Practitioners and enforcers should be included in the process. A code of
ethics should be part of the structure. A timeframe of about ten years was anticipated to yield the
first educated Fire Safety Engineers (four-year programme) based on a common core curriculum,
and thus to reach a full organization of the profession.

FprCEN/TR 17524:2020 (E)
From all these initiatives, the consortium presented its cost-benefit analysis for the implementation of
FSE in Europe. They concluded:
“Under the condition that fire safety engineering is fully implemented in the EU area, this would
correspond to a saving in the order of €0,3 B to €1 B on an EU scale. Compared to these savings, the costs,
necessary to introduce and maintain fire safety engineering in the EU (i.e. costs for research, education
and standardisation) are marginal” (estimated to €28 M).
5 Additional programme
CEN TC127 WG8 was created in 2014 with the aim of pre-standardisation and standardisation of Fire
Safety Engineering. At the time, no mandate had been published for these topics.
The transfer from the CEN TC127 TG1 to CEN TC127 WG8 demonstrated the wish of the European
Commission to highlight Fire Safety Engineering in Europe.
Several programmes for pre-standardization have already been identified by CEN TC127 WG8, including
a performance-based framework, recognition of the profession, identification of needs, strong
relationship with the ISO TC 92 SC4, review of conferences and international exercises, identification of
national trends and feedback from some countries.
Thus the work made by the Benefeu Consortium and the initiatives promoted by it were a strong basis
for CEN TC127 WG8. Nevertheless, 15 years later (2001-2016), an update of the situation was necessary.
Therefore the tasks performed within the Benefeu programme were updated with a revision of the
questionnaire initially completed in 2001. This is presented in Clause 6 for the results of the revision of
the questionnaire in the context of EU in 2001: the update concerns the European countries assessed in
2001. The analysis will identify the work performed in the past 15 years in these European countries.
Since 2001 the European Union has been enlarged from 15 to 28. Thus the questionnaire has also been
completed by the new member states in the European Union. Clause 7 will analyse the situation across
the 28 countries of the European Union in 2016 (some countries did not respond, so the number of
countries was reduced to 22).
Clause 8 will identify the state of the art of Fire Safety Engineering in 2016 compared to the state of the
art in 2001. It includes examples from the SFPE Performance-Based Conference in 2016 that are
representative of the application of FSE in performance-based codes in many countries.
6 Updated survey of EU member states in 2001
6.1 Survey conditions
All the questionnaires filled in 2001 were available as original Excel files. Then the questionnaires were:
• Given to the participants to WG8 in order that they update the content of the questionnaire filled by
the regulators of their country in 2001. Members of the WG8 were free to contact any person to help
complete the questionnaire
• Sent to TC127 members or regulators to the other countries that are not represented by a member in
the WG8.
Then, an updated version was returned to the convenor of WG8 and listed in the WG8 documents.
The members mentioned sometimes that they disagree with some answers given in 2001, indicating that
the answers may include some subjectivity.
In 2001, the questionnaire included the regulators’ position and the practitioners’ position. In this
updated version, a single view is taken into account, considering that only “changes” are indicated.

---------------------- Page: 11 ----------------------

FprCEN/TR 17524:2020 (E)

A large percentage of the eighteen 2001-member states (given as 2001-MS in the following clauses)
completed the updated questionnaire:
• 16 countries updated their questionnaire:
• France;
• Luxembourg;
• Germany;
• UK;
• Sweden;
• Norway
• Finland;
• Switzerland;
• Austria;
• Spain;
• Italy;
• Denmark;
• Ireland;
• Portugal;
• Greece; and
• Netherlands.
• Only two questionnaires were not updated, despite several contacts with experts in those countries.
In the analysis it was assumed that no changes occurred in these countries in the past 15 years:
• Iceland; and
• Belgium.
From the different updated questionnaires, the analysis focussed on the changes. If no change was
recorded, or very few changes (for example if only one country made changes), the report will not present
it.
The reader should refer to the Benefeu final report [1] to find the analysis made in 2001.
6.2 Fire regulations
The date of the main fire regulations in the countries is mentioned. A date later than 2001 shows that a
change of the regulation has been made. Figure 2 indicates the number of countries mentioning a date
later than 2001, so introducing a change in regulations since 2001.

kSIST-TP FprCEN/TR 17524:2020
FprCEN/TR 17524:2020 (E)
Where countries updated their regulations but without fundamental changes, the initial date is
mentioned, as in France, with the 1980 decree.
It appears that 11 countries of the 18 substantively changed their regulations since 2001. These national
initiatives indicate possible regular adaptation of the regulations to the latest knowledge, to the
innovative construction and systems, field experience and data from fires.

Fire regulation - Is there a new regulation since 2001?
Key
1 Yes
2 No
3 No answer
Figure 2 — Change of regulation
6.3 Enforcement of the fire regulations
The enforcement of the regulations was already in place in 2001 by all countries at the planning stage.
Nevertheless, it is noticed that controls have been strengthened by some countries during construction
and use. Figure 3 shows that three new countries (Denmark, Portugal and Norway) have introduced
controls during construction and two countries have introduced controls during the use of the building
(Italy and Denmark). Thus a very limited number of countries have no controls during the construction
phase (Italy) or during use (UK, Finland and Austria).
This indicates the current mandatory controls to ensure the application of the regulations. None of the
countries has reduced its level of controls.

The type of supporting documents (plans, tests, calculations, expert judgement) or supporting
assessment (third-party) required by the regulation was already strong in many countries in 2001, but
has been reinforced 15 years later in some countries (Italy and Greece) by introducing in the regulations
requirements for calculations, expert judgement and third-party assessment (see Figure 4).

6.4 Societal goals and functional requirements
While the main regulatory goals (safety of occupants, firefighters and neighbours) are unchanged in all
countries, other possible goals were not covered in the 2001 report. Few changes in the regulatory goals
were recorded since 2001. Denmark has focussed the goals of its regulation by excluding property and
structure protection as a regulatory goal. Finland has extended its regulatory goals to include protection
of business, heritage and social activity (see Figure 5).
Descriptions of the conditions to achieve these goals have been reinforced in the regulations by a better
description of the functional requirements (see Figure 6).

6.5 Technical details in the regulation
Figure 7 shows that the regulations have evolved to include more technical details in the regulations. In
2001, less than half of the countries included technical details in the five fire safety-based subsystems.
Now at least half of them have included in their regulations the technical details for fire prevention and
protection. However, technical details for firefighter intervention remain low, although they have
increased by 40%.
This may indicate that there remains a lack of technical knowledge that limits the introduction of these
details in the regulations.

6.6 Alternative approval system or derogation
The application of prescriptive regulations requires flexibility to justify architectural/innovative
solutions that do not comply with the regulations.
Where the regulations do not always include guidance on how to address such issues, the authorities
must assume responsibilities without a framework.
In 2001, most of the countries (17 of 18) approved designs based on calculations, only 14 accepted ad-
hoc tests and 15 expert judgements (see Figure 7). 15 years later, the use of calculations is now accepted
by P
