CD-DTU

CD-DTU by CSTB is a software tool developed by the Centre Scientifique et Technique du Bâtiment (CSTB) for the calculation and design of thermal bridges in buildings.

The purpose of CD-DTU is to evaluate the thermal performance of building components, specifically addressing the issue of thermal bridging which can lead to energy losses and potential condensation problems.

CD-DTU can assess various types of thermal bridges, including those occurring at interfaces between building elements (such as floors, walls, and roofs), as well as details within those elements (such as connections and openings).

CD-DTU utilizes the finite element method (FEM) to simulate heat transfers through building components. It takes into account material properties, geometrical configurations, and environmental conditions to provide accurate calculations of thermal bridges.

Yes, CD-DTU can be used to determine compliance with building energy standards and regulations by helping designers optimize the thermal performance of building components and ensure compliance with energy efficiency requirements.

Yes, CD-DTU is applicable to both new constructions and renovation projects. It can be used during the design phase to optimize thermal performance, as well as in retrofit projects to assess potential improvements and evaluate their impact.

CD-DTU is designed to be user-friendly and accessible to non-experts. It provides a graphical interface that simplifies the input of data and interpretation of results, making it easier for architects, engineers, and other building professionals to use.

Yes, CD-DTU can handle complex building geometries and evaluate thermal bridges in various types of constructions, including residential, commercial, and industrial buildings.

Yes, CD-DTU allows for the assessment of different thermal bridge mitigation measures and their impact on the overall thermal performance of building components. It helps designers evaluate the effectiveness of various design strategies.

Yes, CD-DTU is widely used in the building industry by architects, engineers, energy consultants, and researchers. It has become a standard tool for the evaluation and optimization of thermal bridges in building designs.
