The FRISSBE team consists of competent and highly skilled researchers with extensive knowledge and experience in fire safety science and materials engineering. The team is led by the ERA Chair Holder, Grunde Jomaas, who is a world-leading fire scientist with more than twenty years of research experience. The team gathers unique researchers in the region and it aspires to be recognised worldwide for research excellence in the fire-safe sustainable built environment. We strive to make our research of the highest international standard and pledge that our communication with users and stakeholders will be transparent and comprehensible.
FRISSBE, as part of ZAG (Slovenian National Building and Civil Engineering Institute) and with InnoRenew CoE as a close collaborator, has access to state-of-the-art technology and research infrastructure and is actively involved in research projects, interdisciplinary collaboration with other research institutes and private partners, research dissemination, innovation, and knowledge-based services (consultancy).
We recognise the challenges in achieving a sustainable built environment, where many new construction materials, systems and technologies are being incorporated to reach the sustainability goals set out at various socio-political levels. These ambitious goals bring new fire hazards and risks that are essential to address for sustainability to be truly accomplished. Thus, we aim at tackling the emerging challenges to ensure future sustainable and fire-safe built environments that contribute to local, regional and global sustainability goals.
Our mission is to use our state-of-the-art laboratory facilities for research that increases the understanding of the fire behaviour of construction materials and systems. This high-quality research – carried out at various scales – enables a fire-safe sustainable built environment. We investigate the fire behaviour of timber, biobased materials and engineered wood products, modern and innovative energy solutions, and other sustainable construction products that emerge because of the constant development in the built environment. Our research strengthens the educational programmes at the University of Primorska, and it is also used to provide safety recommendations for industry and to educate professionals through workshops and customized courses.
Our vision is to be a global center for fire research related to the development of a built environment that is both fire-safe and sustainable. We will achieve this through an interdisciplinary approach that considers all relevant aspects in a holistic evaluation of the full life-cycle contributions of fires in the built environment. Through dissemination of our findings, we want to improve the competence of professionals and the quality of educational programmes. Finally, the outcomes of our research will ensure that sustainability calculations are not optimized without considering the contributions from fire, all while making sure the built environment remains resilient and provides safety for its users.

The FRISSBE project and the newly ZAG established department with the same name strive to create and support a strong R&D centre focused on fire research in Southern and Central Europe. In FRISSBE, the key to success in terms of performance and impact lies in an integrated approach, covering R&D on methods, materials and structures, graduate and postgraduate training, complementary research on, e.g., bio-based materials and recycled materials as well as solid industrial research.
This is achieved through a broader interactive ecosystem, consisting of the FRISSBE ERA Chair as well as other units of the host institution and two strongly affiliated institutions: the InnoRenew CoE, established under the H2020 WIDESPREAD-2-Teaming: GA No. 739574, providing excellence in complementary bio-based materials research, and the University of Primorska (UP), complementing the ecosystem with wider multidisciplinary research, bachelor's, master's and doctoral degree-granting function, and stronger interaction with peers. Both institutions firmly expressed their willingness to cooperate with the FRISSBE ERA Chair in the project proposal phase, and at the moment the cooperation is successfully ongoing and is presented by mutual applications for competitive funds, research visits and other joint activities.
ZAG was established in 1949 when the People's Republic of Slovenia founded the Building and Civil Engineering Institute. In 1952, it was renamed to Institute for Testing and Research in Materials and Structures (ZRMK). After Slovenia became independent, new conditions in 1994 led to the division of ZRMK into public and private parts. The laboratories and most of the research activities were transferred to the public research institute, ZAG. One of the fundamental objectives of ZAG was to continue the tradition of the research and professional work of the ZRMK, which served since its very establishment as one of the leading civil and building engineering institutes in then Yugoslavia. After more than a quarter-century of independent operation, ZAG is successfully navigating the outlined path. We have gained recognition both at home and even more so abroad. We are an equal and active member of numerous important international associations dealing with the broader area of construction. According to the relevant indicators, we are entirely comparable to the best similar European institutes.
The InnoRenew CoE has been successful in hiring researchers and support staff from abroad (57 employees in 2019, nearly 50% from abroad, including from outside of Europe). It is supporting the beneficiary and the ERA Chair holder by transferring its practices to establish strong recruitment and retention policy that will make ZAG and FRISSBE an attractive workplace, with a culture of engagement and employee participation in the sustainability of the Institute.
Universitiy of Primorska has made the ERA Chair holder a full professor and he will contribute to the university through a part-time research and teaching position at the Faculty of Mathematics, Natural Sciences, and Information Technologies (FAMNIT), where he will organise and deliver courses in the Sustainable Built Environments MSc program and supervise students in the Renewable Materials and Healthy Built Environments PhD study programme. The beneficiary (ZAG), in turn, provides internships and research infrastructure for students from these programs to gain practical research experience and conduct their studies.

NEW BUILDING, STATE-OF-THE-ART EQUIPMENT, YEARS OF EXPERIENCE…
The Slovenian National Building and Civil Engineering Institute (ZAG) has been dealing with fire engineering and testing for more than 40 years. Over time, the expansion of work areas and work itself lead to a strategic decision: the existing laboratory in Gameljne near Ljubljana needed to be replaced with a new laboratory, which would also strengthen the scientific and research excellence of the staff.
The newly established Fire laboratory is now located in Logatec and it offers state-of-the-art fire research with high-fidelity measurements. The new building is home to ZAG’s new Department for Fire-Safe Sustainable Built Environment (FRISSBE) that consists of two units:
%%SLIKA_1%%
The FRISSBE team is a part of a larger group at ZAG’s Fire laboratory and thus works closely with The Fire Laboratory and Fire Engineering Unit which consists of the following employees:
The Fire laboratory is equipped with facilities for standard testing for building and maritime industry, which is, together with some other special equipment, also used for research purposes. In general, testing is focused on pre flashover fire conditions considering reaction to fire properties of different building materials and fully developed fire conditions at fire resistance tests. The laboratory boasts a unique façade research set-up which allows fire testing of different large scale mock-ups with real time heat and smoke measurements along with FTIR analyses of exhaust gases of up to 10 MW of released heat. Furthermore, the laboratory offers bespoke small, intermediate and large scale experimental designs with oxygen calorimetry and FTIR measurements.

This project supported the National Fire Protection Association (NFPA) Electronic Safety Equipment Technical Committee in assessing image quality evaluation methods for thermal imagers used in the fire service, as defined in NFPA 1801 and NFPA 1930.
The work addressed limitations of the current “Image Recognition Test,” which has shown inconsistencies and limited alignment with perceived image quality in operational conditions. A review of existing metrics was conducted alongside a survey of image quality assessment approaches from other industries, focusing on models that correlate with human perception.
The study found that advanced perceptual image quality models could be applied to thermal imaging; however, their implementation is constrained by the lack of suitable infrared datasets. The project therefore recommends the development of representative fire service thermal image datasets to enable validation and adoption of improved evaluation methods.

This research project addresses fire risks associated with lithium-ion batteries (LIB) across a range of applications, with particular focus on e-mobility, battery energy storage systems, and their integration into the built environment. The growing adoption of these technologies and the increasing frequency of related fire incidents present critical safety challenges for industry, fire brigades, and regulators alike.
The project combines analysis of existing statistical data, review of the regulatory framework, development and validation of new methodologies for quantifying LIB fire risks, and experimental fire testing in a controlled laboratory environment. Key areas of investigation include thermal runaway mechanisms, toxic gas emissions, re-ignition behaviour, and the risks posed to firefighters during intervention.
The research is closely linked to the development of practical, operationally applicable solutions, including assessment of the effectiveness of different suppression systems and firefighting tactics, and the definition of criteria for safe post-intervention handling.
The project is carried out in collaboration between the Slovenian National Building and Civil Engineering Institute (ZAG) as lead research partner, and operational and academic partners (Ljubljana Fire Brigade and the Faculty of Industrial Engineering Novo Mesto) ensuring direct knowledge transfer from research into practice.
Outcomes will be consolidated into a comprehensive safety and recommendations framework to support improvements to existing guidelines, potential regulatory updates, and targeted training for both professional and volunteer firefighters.

Societies are becoming more aware of climate change, and there are many efforts to create a more sustainable planet. One of these efforts is the development of lithium-ion batteries and their integration into various applications, such as electric vehicles (EVs). Lithium-ion batteries are increasingly present in our daily lives, and they pose fire and explosion hazards for several reasons. The consequences of such hazards can be extensive, affecting society, particularly the population, first responders, and maritime communities, as well as the built environment. Understanding the fire behaviour of Li-ion batteries is paramount for designing effective mitigation strategies to deploy this technology safely. The specialised communities undertake significant efforts to understand the hazards posed by batteries and develop guidelines for safer use. The purpose of this project is to:

This initiative will increase the already rising rate of new PV installations. However, putting a PV system on the roof has been shown to increase the extent of damage in case of a re,2 both because it can be the source of a re (including the DC and AC parts of the installation) and because the consequences of a roof re increase. Current estimates show that the annual expected number of res related to PV systems is 29 res/GW of the installed power.3 Many causes (in cases where the PV systems were the source of re) were related to the processes of installation and maintenance of the PV installation.

The most common type of façades used in new construction and renovation projects are ETICS (External Thermal Insulation Composite System, 65%), cavity walls (19%) and ventilated facades (12%). ETICS systems are also the predominant type of façades installed in Slovenia for renovation of existing buildings and for new constructions. Considering the significant market of ETICS systems throughout Europe, along with the fire risk associated with façade systems, it is of great priority for the society and research community to increase the understanding of the fire behaviour of ETICS. The project will carry out an extensive experimental study that combines large-scale and mid-scale experiments to identify the sensitivity to failure of ETICS systems in a fire scenario.

The project will be focused on developing a Thermo-hydro-mechanical (THM) densification process in combination with other suitable wood modification treatments in order to add value to low quality wood species that traditionally weren’t use in construction. Then the optimized wood modification procedure will be applied into engineered timber products (EWPs) with construction element size to verify its improvement of mechanical properties and performance under fire.

This project investigates the mechanical vulnerability of intumescent coatings used for fire protection of steel structures, particularly bridge cables and profiles. Through ambient mechanical tests and coupled thermo-mechanical experiments, it aims to quantify how steel deformation, profile geometry, coating type, and coating thickness influence cracking, detachment, or fall-off of the insulation. The results will help define admissible deformation limits that designers can use to select suitable coating systems and improve fire safety.
The focus of the new fire research laboratory building in Logatec is to offer state-of-the-art fire research with high-fidelity measurements through ZAG’s new department for Fire-Safe Sustainable Built Environment (FRISSBE). The building is equipped with experimental facilities for reaction to fire and fire resistance research. In addition, it offers a unique façade research set-up with measurements of combustion products and heat release rate. Furthermore, the building can offer bespoke experimental designs with oxygen calorimetry and FTIR measurements in rooms and under hoods. Although the building is new, the two teams that runs it are both very experienced in terms of standard testing and fire science research.
Areas of work in the fire laboratory:
Key equipment in the fire laboratory:
The safety and performance of battery technology for space exploration are highly relevant as they are used for several applications (mobility devices, energy storage, crewed-space vehicles, small gadgets, satellites, etc.). Primary (non-rechargeable) and secondary (rechargeable) battery technologies would operate under extreme operational conditions, such as vacuum, vibration during launch and orbit, a wide temperature range, ionising radiation, and so on. According to NASA, the technological specifications of energy storage technologies for future planetary science missions must have high specific energy (≥250 Wh/kg) and long lifespan (15 years, 50,000 cycles) for rechargeable batteries, and more than 500 Wh/kg for primary batteries. Lastly, both primary and secondary batteries must operate under extreme conditions (-40 °C to 460 °C). Lithium-ion batteries are widely used in spacecraft applications; however, LIB technology still requires substantial improvement, as significant challenges remain in component degradation, thermal stability, and safety. Hence, studying and testing the thermal stability and safety of LIB and other battery technologies is indeed of high importance for future space missions.
The fire laboratory at ZAG-FRISSBE offers the opportunity to conduct thermal stability and safety studies on battery cells of various technologies for spacecraft applications.

Figure 1: The Acceleratory Rate Calorimeter (ARC) assembly (left), and the standard and EVx combustion chambers (right). The assembly comprises combustion chambers that enable testing of cell components, from small cells (coin) to large battery cells (up to 100Ah). Both chambers sit in the blast box (left), where the experiments take place. The electronic cabinet (left) has the PC workstation, the ESU/OSU (for control and data acquisition from the calorimeter and add-ons), the PSU/PSU+ (provides power to the ARC system), and the CPU (for specific heat capacity measurements).

Figure 4: Flames appearing after thermal runaway during the test with a battery pack. The duration of the flaming was very short, corresponding to the combustion of the gas released during the forced thermal runaway. The flames were confined to the gas phase and did not ignite any materials in the battery pack or the test setup.

Figure 5: Heat-seek-wait (HSW) test conducted in the ARC on LIB coin cells. In the HSW test, the cell is heated up in steps in semi-adiabatic conditions. That is, for each heat-up step, the ARC waits an additional step until self-reactions occur in the LIB cell, thereby identifying the onset of thermal runaway and other characteristic properties (e.g., delay time).
For any interested parties using the facilities, administrative and logistical coordination is handled by ZAG, which provides the specifications for all equipment available to investigators interested in utilising the facility. The respective research teams implement and conduct the experiments. The ZAG Technicians, who have been trained on the various apparatus, will introduce them and support the implementation of the experimental campaign.
Any proposed research projects can be funded by ESA, taking into account the operating costs of the laboratory facility. The ESA Continuously Open Research Announcements (CORA) programme offers funding for researchers from ESA member states or through the OSIP Platform. Note that ESA can fund up to € 50,000 per proposal, which includes the utilisation costs of the testing equipment and laboratory (excluding consumables and travel expenses). Before submitting any application to ESA, please don't hesitate to contact us for further details and information on the scope of the desired experiment or other activities.
