Smart energy supply & e-mobility for a modern housing development
7 Lerchen Kloten, a new-build project that looks to the future of living
The seven residential blocks are being built in phases, with the first two buildings (Blocks E and F) already successfully in use. Even at this early stage, it has become clear just how important a well-thought-out energy and mobility strategy is for a development of this scale: high efficiency, clear billing processes and a smart infrastructure that grows with the residents’ needs.
Two ZEVs and a smart solution for two building clients
A distinctive feature of this project is the implementation of two separate ZEVs.
This became necessary because two different client organisations are active on the site, meaning that two independent energy management models are required.
A ZEV enables locally produced energy to be used efficiently within the building and ensures that all energy consumption is billed transparently. Thanks to the project’s dual structure, both client groups nevertheless benefit from a uniform technical architecture that integrates seamlessly into the overall development.
For residents, this means:
- Fair billing for locally generated and purchased electricity
- Reduction in unnecessary grid charges
- Clear meter readings for each household
- A sustainable energy ecosystem that reduces costs and CO₂ emissions in the long term
Once the overall project is complete, the processing of ZEV electricity purchases will be handled by Infrastruktur Zürichsee AG, a professional partner that ensures accurate billing and structured consumption data.
Energy reports for heating & hot water – transparency at the touch of a button
In addition to electricity, the recording of heating and water consumption also plays a key role in ensuring transparency regarding operating costs.
Here, the development relies on the Invisia energy management system, which automatically collects all data, validates it and transmits it to the management team in the form of structured reports.
This offers a clear advantage for property management:
- Significant simplification of the annual service charge statement
- Transparent data that tenants can understand
- Less manual data entry and fewer sources of error
- A precise basis for internal optimisations and cost savings
Thanks to this digital transparency, energy management becomes a daily support tool, rather than something that only comes into play once a year as part of the billing process.
E-mobility with amina: a scalable charging infrastructure with a future
A charging infrastructure for electric vehicles has already been implemented in the first construction phase. amina charging stations are being used, which impress with both their robust technology and their flexible scalability.
As experience shows that demand for charging points in residential developments is constantly rising, the system has been designed so that additional parking spaces can be easily electrified. The charging infrastructure thus grows in line with residents’ mobility patterns, without the need for structural alterations or costly retrofitting.
At the same time, the Invisia system ensures:
- Intelligent load management
- Fair and transparent billing per charging point
- Stable operation even as utilisation increases
- Optimised use of ZEV electricity for charging electric cars
This creates a sustainable mobility solution that combines environmental benefits with practical everyday use.
Elektro Life, a reliable implementation partner
Elektro Life is responsible for the electrical installation of the entire system.
With their structured project management, they ensure that the infrastructure is implemented smoothly, from the sub-distribution board right through to final commissioning.
A reliable installation partner is a crucial factor for success, particularly for projects spanning several years and construction phases.
