The BTS (Higher National Diploma in Building Technology) is a key step for anyone aspiring to work in the construction and architecture sector. With its challenges related to technical mastery, project management, and risk assessment, it’s essential to be well prepared for the exam topics. In 2025, we’ll see a variety of topics, ranging from real-life case studies to the analysis of modern materials or techniques, particularly with the integration of innovative resources such as those offered by major players such as Saint-Gobain and Leroy Merlin. The diversity of topics reflects the richness of the field, where understanding standards, mastery of digital tools, and knowledge of companies such as Bouygues Construction and Schneider Electric play a key role.
What are the traditional and innovative topics covered in the BTS (Higher National Diploma in Building Technology)? Over the years, certain topics have recurred regularly, reflecting their fundamentals, but they have also been enriched with more innovative themes to meet the challenges of 2025. These often include questions on the strength of materials, the design of building envelopes, and energy performance assessment.
Recurring Topics in Strength of Materials and Structures
Exams frequently offer topics related to the strength of reinforced concrete beams, structural stability, or load calculations. For example, a topic might involve designing a reinforced concrete beam based on given forces, while complying with applicable standards. The key to success here lies in mastering calculation rules and the ability to interpret technical specifications.
To succeed in these tests, it is recommended to practice with corrected questions such as those from TEHUA or to consult the documentation available on platforms such as
BTS Construction Many students encounter exercises requiring them to apply RDM (Resistance of Materials) formulas, create tables with numerical values, or justify their technical choices.Discover the BTS Construction program, a program that prepares you for careers in construction and public works. Learn the essential technical skills to design, build, and manage construction projects while acquiring a solid theoretical foundation.

Another popular topic involves the study of materials such as concrete, wood, or rock wool. Questions may focus on their composition, their behavior in a climatic context, or their environmental impact. For example, how do you choose between Knauf or Isover for insulation in a public building, considering thermal resistance and durability?
Students often have to prepare a comparative table of properties, including thermal conductivity, compressive strength, or compatibility with other materials such as those from Saint-Gobain or Rocamat. These topics require a good understanding of technical data sheets and the ability to quickly synthesize information.
Material
| Thermal Conductivity | Durability | Cost | Examples | Reinforced Concrete |
|---|---|---|---|---|
| Type I: 1.4 W/m·K | Very Good | High | Rocamat, HeidelbergCement | Rock Wool |
| 0.036 W/m·K | Good | Medium | Isover, Knauf | Wood |
| Variable | Very Good | Variable | Leroy Merlin | Building Envelope Case Studies |
There are also numerous topics related to the design of a building’s thermal and acoustic envelope. For example, candidates may be asked to study a specific case: the renovation of the perimeter of a high school or gymnasium. The key is to evaluate insulation, ventilation, and energy management, using recommended materials such as those offered by Bouygues Construction or Schneider Electric.
Required skills include reading plans, performing heat loss calculations, and proposing innovative solutions, particularly using recycled or low-carbon materials, in collaboration with suppliers such as Saint-Gobain or Leroy Merlin.
