Software for Building Science

Software for Research and Practitioners

The Institute for Building Climatology at Dresden University of Technology (Faculty of Architecture) investigates the theoretical basis of combined heat, moisture, air, and salt transport in building materials, and also researches other areas of building science. An important goal of our research work is the dissimination of new knowledge to other research institutes, and practitioners. Therefore, we continuously integrate new findings in our user friendly software and calculation tools.

Our software programs shall help other research institutes in their work, assist students in learning fundamentals of builing physics, and support the work of civil engineers, architects, and others working in the field.

The longterm experience in the area of combined heat, moisture, and salt transport processes also benefits expertises and research reports. For instance, our software can be used during the planning phase to estimate the condensation risk of a construction under various environmental conditions, or to investigate the impact of thermal bridges. The software can be used to determine the causes of damage to constructions or materials, or to test new materials for potential application areas and limits and help optimize materials accordingly.

Available Calculation Tools

Our software is designed and implemented such, that a very short learning phase should suffice and results can be obtained quickly. The programs COND and DELPHIN cover simulation-based analysis and optimization of constructions, assemblies of building materials, and construction details. The focus of the hygrothermal room model THERAKLES lies on simulating thermal comfort in summer for checking code-compliance, as well as annual building energy simulation.

COND is a software for the hygrothermal evaluation of building envelope constructions, which uses an analytical calculation method that considers the redistribution of internal condensate.


DELPHIN is a comprehensive numerical simulation tool for the combined heat, air, moisture, and matter (e.g. salt) transport in porous building materials.



THERAKLES is an easy-to-use simulation tool for predicting thermal comfort in summer and winter, and energy gains and losses for room spaces. It is a physically detailed model and has a powerful numeric solver engine for efficient calculation.

NANDRAD is a building energy performance simulation, specialized on large massive buildings with many zones and detailed construction models (walls, floors, ceilings, ...).

MASTERSIM is a simulation master for coupled simulation of models encapsulated in Functional Mockup Units (FMU), and a program library with FMU import and simulation functionality.
