At Hofwisenstrasse 48 in Rümlang, enshift is implementing a combined solar and heating solution for long-time partner Helvetica Property Group. Over the past year, we have realized multiple projects together, supporting their portfolio on the path toward more efficient and climate-friendly energy systems. The photovoltaic installation on this mixed use building is already in operation and delivers 480 kWp of solar capacity, supplying clean electricity directly to the building, with an additional pending heating installation in march.
Once fully operational, the combined installation will provide 620 kW of renewable capacity and reduce emissions by approximately 68%, corresponding to around 68.2 tons of CO₂ per year. Together, the solar installation and heat pump create a fully electrified energy system. On-site solar generation supplies part of the building’s electricity demand, while the heat pump converts that electricity into renewable heat. This integrated approach reduces operating costs, improves energy performance, and significantly lowers the property’s long-term carbon footprint.
The rooftop photovoltaic system is already in operation and delivers 480 kWp of installed capacity. The system makes use of approximately 2,880 m² of available roof area and produces clean electricity directly on site.
A share of the solar power is consumed within the building, reducing grid dependency and stabilising long-term energy costs. The remaining electricity is fed into the local grid, contributing additional renewable energy to the surrounding area.
The installation is operated through enshift, meaning we are handling financing, installation, operation and maintenance over the long term.
In parallel, a new 140 kW heat pump system is being implemented to replace the existing fossil-based heating solution. The system is designed as a monovalent heat pump, meaning the building’s heating demand will be covered entirely by renewable, electrically driven heat generation.
Construction of the heating system is scheduled to begin in March, with commissioning planned by the end of the month. After completion, the building’s heat supply will be largely decarbonised, delivering a reduction of nearly 58% in heating-related emissions.
The heat pumps provide sustainable heating in winter – independent of outside temperatures
Helvetica benefits from state-of-the-art technology and cost savings without needing to invest its own capital
Combining with a powerful PV system enables the use of self-produced solar energy, increasing self-consumption and economic viability
In addition to reducing operating costs and CO₂ emissions, the solution improves the property’s energy rating, increases marketability, and reduces long-term vacancy risk
Thanks to enshift’s PLUS model and data-driven, interdisciplinary planning, we reduced investment requirements by 25-40 % compared to conventional approaches. Our high implementation volumes, direct sourcing, and coordinated delivery eliminated risk and complexity — enabling Helvetica to maintain liquidity, preserve financial flexibility, and accelerate execution allowing operating capital to remain focused on the core business.
