The Context
Mr. Steffen, owner of a commercial building in Le Landeron, was facing significant energy costs and an aging oil heating system. Rather than enduring these expenses, he chose to invest in a sustainable transformation, combining cost reduction, improved comfort, and long-term property value.
Already a Neho client for a real estate transaction, he took advantage of the new energy renovation service developed in partnership with Nao Energy. This collaboration allowed him to be supported at every stage: technical diagnosis, financing plan, administrative procedures, and project management.
The Renovation Work
The renovation was designed in a consistent way to maximize the building’s performance:
-
Installation of bifacial HJT photovoltaic panels, capable of producing 32,000 kWh/year thanks to their high efficiency.
-
Replacement of the oil heating system with a modern, high-performance heat pump, reducing emissions and dependency on fossil fuels.
-
Addition of an eco-friendly air conditioning system, optimized for the building’s professional use.

A High Value-Added Project
Thanks to this work, the building is now partially energy self-sufficient, offering significantly reduced operating costs and improved thermal comfort. This strategic choice enhances its attractiveness to tenants and ensures better long-term value.
This renovation perfectly illustrates how a well-planned energy project can generate both substantial savings and lasting property value, while also contributing to Switzerland’s energy transition.
