近年来，使用木材作为建筑材料已变得流行，特别是用于住宅。其使用的先决条件之一是足够的消防安全。技术措施，特别是喷水灭火系统和烟雾探测系统，装备精良的消防队和更好的知识，在木结构的结构防火设计领域允许在更广泛的应用领域使用木材。在自然火灾条件下，对木制模块化酒店进行了全尺寸测试，以了解不同消防安全概念的效率。在第一个系列中，研究了技术措施的效率，特别是快速响应喷水灭火系统。第二个系列展示了结构防火安全措施的可能性和局限性。特别注意易燃房间表面对房间内外火灾增长和火灾蔓延的影响。这些测试扩大了用于验证自然火灾模拟（温度、火灾蔓延等）的实验数据。并对木结构耐火极限计算方法进行了验证。
In recent years the use of wood as a building material has become popular, especially for dwellings. One of the preconditions for its use is adequate fire safety. Technical measures, especially sprinkler and smoke detection systems, well equipped fire brigades and a better knowledge in the area of structural fire design of timber structures allow the use of timber in a wider field of application. Full scale tests on wooden modular hotels were performed under natural fire conditions to look at the efficiency of different fire safety concepts. In a first series the efficiency of technical measures, especially fast response sprinkler systems, was studied. The second series showed the possibility and limits of structural fire safety measures. Special attention was given to the influence of combustible room surfaces on fire growth and fire spread inside and outside the room. The tests enlarged the experimental data for validation of natural fire simulations (temperatures, fire spread etc.) and for verifying the methods for the fire resistance calculation of wood constructions.
