Discover EnergyDesign software basic features and take a glimpse of its user interface.


Complex 3D models of a building's shell can quickly be constructed without advanced CAD skills. The model defines geometry, shading, construction types and materials, openings, thermal bridges, energy flows (heating, cooling, lighting, ventilation), DHW and renewables.


All the input is fed into the calculation engine which implements the ISO 13790 methodology to calculate the annual energy consumption and class.


Energy saving scenarios can then be easily added to study improvements in efficiency and calculate Return On Investment.


Energy performance results are visualized with graphs and charts, detailed drawings of insulation, shading, shell facades and openings.
EnergyDesign produces a large number of reports that document the building's energy characteristics and the calculation results.


EnergyDesign has been designed from the ground up to allow for easy parameterization of national standards.



Correct mistakes earlier – spend less time later with more complicated changes, offering improved customer satisfaction.

No time wasted importing/exporting data into/from different tools. Simulation and calculations tools, 2D and 3D visualization, drawings, reports, libraries and documentation within the same application.

Minimize the time spend browsing materials and equipment. The libraries come preloaded with a large number of data (materials and equipment available on the market). New data can be easily added to the libraries.

Every new project has default values (where possible) for its most important parameters. These values have been carefully selected and significantly speed up the building modeling.

Frequent references to the standards textbooks can be distracting and interrupt your workflow. Important information, formulas and excerpts from the standards are included in the help.


Ensure that your design satisfies regulations without oversizing equipment.

Prevent numerous changes later once the build is in progress.

Ability to take off material volumes and amounts means less overspend – which in turn leads to less waste on unnecessary materials being ordered and not wanted/ used.


TiSoft EnergyDesign helps you assess energy efficiency and performance of any building according to the standard ISO 13790, make all the necessary calculations ensuring standard compliance, and produce a variety of drawings, floorplans, schematics and reports. It will also provide a wealth of information that will assist you in creating energy saving scenarios for sustainable design.
