UCEEB ČVUT - Univerzitní centrum energeticky efektivních budov ČVUT v Praze

We perform large-scale interior and exterior fire tests to evaluate the behaviour of materials and products in a fire. We carry out tests on a medium and large scale, both inside the laboratory and outside on the experimental area. We focus in particular on obtaining the fire-technical characteristics of building products and individual objects for the purposes of mathematical modeling, indicative determination of the fire resistance of non-load-bearing building structures and determination of the reaction of facade systems to fire. We also carry out tests of the effectiveness of extinguishing and cooling with low-pressure water mist on a real scale for extinguishing and cooling with water mist or evacuating people.

We are interested in evacuation from an enclosure, such as buildings or means of transport. We organize evacuation drills, during which we focus both on the reaction of people to the announcement and on the movement characteristics of people. We verify the possibility of safe evacuation with mathematical models.
We verify the behaviour of structures and products during a fire, the effectiveness of firefighting systems or the possibility of safe evacuation with mathematical models, and on the contrary, we use the data obtained from the performed tests to expand or verify the input parameters for mathematical models of fire dynamics.

We offer expert evaluation of buildings in terms of fire safety of buildings and consulting in the field of fire engineering (so-called performance-based design), fire legislation and testing.

Main Team Activities

We prioritize research and testing of specific materials, structures and systems for fire-safe buildings.

We conduct large-scale tests with real fire scenarios in interior or exterior conditions.
We determine the reaction to fire class with the Room Corner Test, where one large-scale fire test with a sample area of up to 30 m² replaces a series of normal small-scale tests in cases where it is not possible or appropriate to test the product on a small scale.
We perform calculations of fire resistance of structures and mathematical modeling of fire dynamics, extinguishing and evacuation of people.
We develop and optimize building elements from the point of view of fire safety.
We are engaged in consulting and advisory activities in the field of fire engineering.

Envilop

Envilop is a proposal for a solution for a lightweight panel-type perimeter skin based on wood. The light envelope was designed as part of the Intelligent Buildings project (CZ.1.05/3.1.00/13.0283) from the Operational Program Research and Development for Innovations of the Ministry of Education and Culture, which is financed by the EU and the state budget of the Czech Republic.
