The refurbishment of older apartment buildings in the Czech Republic is increasingly raising questions about the condition of infrastructure beyond heating, insulation and energy consumption. Entrance systems, internal communication equipment and building access controls are among the installations that may require attention as residential properties age. While these improvements are not directly required by European building energy legislation, they can form part of broader renovation programmes intended to extend the operational life of existing properties.
A substantial proportion of Czech residential accommodation was constructed several decades ago, and many buildings continue to operate with electrical and communication systems installed during earlier periods of occupation. Equipment that was originally designed for basic voice communication between entrances and apartments may no longer meet current management requirements. Older installations can also present maintenance difficulties when replacement components become unavailable or when technical faults affect several apartments simultaneously.
The implementation of the European Union’s revised Energy Performance of Buildings Directive is expected to influence renovation activity across the Czech property market. Although the legislation concentrates on reducing energy consumption and improving building performance, refurbishment projects can also provide opportunities to examine other infrastructure. For apartment owners’ associations and property managers, the decision involves determining which existing systems remain functional and where replacement would be justified by maintenance costs, operational requirements or equipment condition.
Michal Kratochvíl, CEO of Czech building access technology company 2N, believes that refurbishment decisions should be based on a technical assessment rather than automatically replacing existing infrastructure. “Renovating a building should not mean discarding everything that is already there. A successful retrofit begins by identifying which parts of the infrastructure can continue serving the building and which need to be modernised,” he said. This approach requires installers to examine the condition of existing wiring and assess whether it can accommodate newer communication equipment.
An example from Prague involves an apartment building approximately 50 years old, where the existing vertical wiring was retained during the installation of a replacement entrance communication system. New entrance panels and apartment devices were connected to the available infrastructure, while additional software enabled communication through mobile telephones and remote administration. The project illustrates one possible approach to refurbishment, although the suitability of retaining older cables depends on their technical condition and the requirements of the replacement equipment.
Where existing wiring cannot be reused, alternative systems may allow entrance calls to be transferred through mobile networks or wireless connections. Some buildings may require a combination of conventional cabling and newer communication technologies, particularly where different sections have undergone renovation at different times. These arrangements can reduce the need for extensive construction work, but their reliability depends on network availability, equipment compatibility and the continued operation of supporting services.
For residential property owners, the cost of replacing entrance systems extends beyond the equipment itself. Installing new cables may require work in stairwells, corridors and occupied apartments, creating additional expenses and temporary disruption. Maintenance requirements, software updates and equipment replacement cycles also affect long-term costs. According to 2N, its equipment is supported by a five-year warranty, with repair services and software maintenance available under the company’s applicable support arrangements. Property managers must assess these conditions alongside the initial installation costs.
The introduction of network-connected access equipment also creates responsibilities involving cybersecurity, resident information and administrative control. Building managers need procedures for granting and withdrawing access permissions, maintaining software and responding to technical problems. Remote administration can reduce the need for some maintenance visits, but it also requires appropriate safeguards against unauthorised access. As renovation activity continues across the Czech residential sector, decisions about communication and entrance infrastructure are likely to become part of wider discussions about maintenance expenditure, building management and the continued use of older housing stock.
