Planning for existing buildings made easy

Digital twins, 3D models and maintenance software digitise existing buildings.

For modern property management, software solutions are an indispensable tool when it comes to efficiently planning construction measures and maintaining existing properties. Such programmes make it possible to analyse the condition of buildings precisely and thus provide current data, which in turn forms the basis for construction measures of all kinds. ISH, the world's leading trade fair for the sector, presents the latest developments and technologies in the field of planning software for existing buildings.

Challenges when planning for existing properties

Existing buildings pose unique challenges for planning and management. A precise inventory is crucial to assess the current condition of the building and identify any measures necessary. And this is where specialist software comes into its own because, if not already available, it permits the creation of detailed digital twins that accurately reflect the current condition of the property. With the aid of such digital copies of the building, developers and planners can determine the renovation requirements more precisely and more accurately estimate both the costs and the resources required.

In addition, software for recording the existing building-services technology and its condition plays a crucial role for building maintenance. Regular maintenance is essential to extend the service life of building-services technology and minimise malfunctions. Using modern maintenance software, work can be planned intelligently and with foresight. The software helps ensure that all necessary tasks are carried out on time without disturbing users or interrupting production processes at considerable expense.

Innovative software solutions at ISH 2025

At ISH 2025, trade visitors can familiarise themselves with the latest software solutions for planning and managing existing buildings:

  • Property-management software: These programs include numerous features for planning and managing existing properties. They help with the creation of inventories, the planning of modernisation projects and the management of maintenance activities.
  • Building maintenance and monitoring: These software solutions enable the building status to be monitored continuously and help to identify potential problems at an early stage. They include features for planning and tracking maintenance activities and help improve the energy efficiency of buildings.
  • Maintenance software: Special programs for the maintenance of building-services technology ensure that maintenance work is carried out on time and that the operational safety of these systems is guaranteed.

Software meets new technologies

Software solutions for the construction industry are now much more than just digital building plans. Planners are relying more and more on 3D planning tools to visualise even complex geometries. Planning in 3D, especially for existing buildings, facilitates collision control and improves transparency.

Digital twins, i.e. virtual copies of buildings, have advantages for both planning and building operation. Changes and conversions can be tested and optimised in the digital environment, which saves costs and has no impact on building operation. Furthermore, the digital twin provides insights into the building's condition and energy consumption during operation and generates alerts when malfunctions or defects occur.

Sustainability and energy efficiency in existing buildings

Rising energy costs and an ever-increasing number of environmental regulations are focussing more and more on the energy efficiency of buildings. Modern software solutions help optimise the energy consumption of existing properties and improve their environmental footprint. Innovative technologies that make these buildings more sustainable and cost-efficient will be showcased at ISH 2025.
