“…Moreover, much attention is brought to the problems with energy conservation in standardised fire testing of combustible elements 10,18 and their potential impact on the development of compartment fires. 19,20 This aspect is essential, as in a real building, the parameters of the walls will affect the growth of fire (in positive or negative). However, in furnace testing, these effects are not quantified, which may promote materials and assemblies that have a higher value of fire resistance rating (and not necessarily lead to a safer building).…”

“…While this is well known for compartment fires, these effects are entirely disregarded in standardised furnace testing, due to the prescribed nature of the thermal exposure. Moreover, much attention is brought to the problems with energy conservation in standardised fire testing of combustible elements and their potential impact on the development of compartment fires . This aspect is essential, as in a real building, the parameters of the walls will affect the growth of fire (in positive or negative).…”

Summary The paper aims to explain the differences found in the heat release rate measurements in a large sample of standard fire tests (EN 1363‐1). A total of 379 tests of vertical assemblies was investigated, all performed in furnace SPARK of the ITB Fire Testing Laboratory, in 2015‐2018. The assemblies were subdivided into two groups—wall assemblies and fire‐rated doors. These assemblies were also compared with the results of the test of a wall built with aerated autoclaved concrete blocks that was considered as the benchmark test. It was observed that walls built with highly insulated sandwich panels require less heat to maintain standard thermal exposure conditions (20%‐30% less) than their counterparts built from gypsum plasterboard or aluminium and fire‐rated glass. In case of doors, it was observed that combustible samples required significantly less heat than the benchmark case (40%‐70% less), which indicates that the combustion of the sample inside of the furnace was an additional, significant source of heat release, that may skew the qualitative assessment of their performance in fire. A more in‐depth discussion of the results is provided, with some ideas on the direction of further developments in fire testing.

versy: the requirement of durability (over 50 years) versus the risk of progress. We need to ensure that construction elements meet the requirements not only at the time of testing, but also that they will be good enough after tens of years of service life. The nature of an applied science involves the problem of equilibrium between simplicity and accuracy. The "breaking even" in the meaning of probably approximately correct model and value. The risk of estimation error, even a small one, could cause in consequence a catastrophic result.All these problems are discussed in the invited paper opening the section, entitled: "Scientific basis and rules of thumb in civil engineering: Conflict or harmony?", examining the meaning and justification of "the rules of thumb" [3] in the construction field, in which science and engineering are so intermingled. Shortly speaking, how much "it is better to be roughly right than precisely wrong" (J. M. Keyness). All the other papers in the Section illustrate those problems in various but very obvious ways. The topics of the papers could be assigned under the headlines that follow. The seminar accompanying the anniversary of ITB, entitled "The Strategy of Construction Research Institutes", presented a compendium of knowledge and strategy of building institutes that co-shape the European construction space. The regulations of ITB stated that the Building Research Institute was established to conduct comprehensive research in order to improve and increase production of construction and road materials, as well as to improve construction technology using all scientific advances. Of course, to create trends in the discipline development is not the task or mission of ITB only. Risk of performance evaluationIn this context, the word "ongoing" in the Section title has been treated both literally and figuratively. All current waiting papers from the editorial civil engineering portfolio have been included into the Special Section. The papers which are presently in the editorial process will be published in the Special Section Part II. In such case we have not only obtained a cross-section of the present publishing activity, but also the characteristic picture of the civil engineering in a flash. Although very randomly created, this picture is a surprisingly comprehensive one.Civil engineering as a discipline of applied science is always seeking for its place on the map of knowledge. Each of the papers included in this Special Section consists of two components: science and engineering balanced in various ways. One of the dilemmas of the civil engineering is the following contro- (W. Węgrzyński, P. Sulik) [8] illustrate a dynamically developing sub-discipline -fire safety engineering. How fire safety requirements shape the development of civil engineering has been considered and documented. The frost resistance is one of the basic attributes of concrete durability. This problem is discussed by J. Wawrzeńczyk et al. [9], focusing on the concrete with granulated blast furnace slag. The subjec...
