Thanks to Signa-Terre’s Energy Monitoring, Rentes Genevoises Reduce CO₂ Emissions of their Real Estate Porfolio by 50%

A visionary collab­o­ration for a greener future: Rentes Genevoises and Signa-Terre. In a world under­going an energy transition, achieving sustainable trans­for­mation requires strategic, informed choices and consistent, long-term commitment. Since 2009, Rentes Genevoises and Signa-Terre, part of the Wüest Partner Group, have worked together with trust and synergy, demon­strating that major challenges can be overcome collab­o­ra­tively.

Due to this collab­o­ration, Rentes Genevoises have been enabled to certify their real estate portfolio under ISO 50001 a decade ago — marking a European first — and to reduce its energy consumption by 50%. This tangible result under­scores the success of their shared initiative.

Rentes Genevoises: A Model of Commitment

Since 1894, Rentes Genevoises have protected and supported gener­a­tions with robust pension solutions. Their real estate portfolio, comprising 39 buildings primarily in Geneva and valued at CHF 574.4 million, lies at the heart of their mission. Managing this portfolio requires signif­icant investment and the ability to antic­ipate legislative, economic, and societal changes. With annual invest­ments of CHF 10 to 12 million dedicated to maintaining and renovating their buildings, Rentes Genevoises exemplify a model of respon­si­bility and dedication essential for the energy transition.

Signa-Terre: Trusted Guidance and Support

Since 2009, Signa-Terre has been assisting Rentes Genevoises with their real estate strategy, lever­aging its expertise in energy management and resource optimization. Through:

• detailed energy audits based on certified data collection processes and actual consumption,
• real-time monitoring solutions,
• and the devel­opment of decar­bonization pathways,

Signa-Terre provides actionable insights and recom­men­da­tions. These tools enable the trans­for­mation of regulatory constraints—such as the 60% CO₂ emissions reduction target by 2030 — into innov­ative oppor­tu­nities.

Ultimately, the primary credit goes to Rentes Genevoises. Their commitment and willingness to invest in ambitious renova­tions bring these solutions to life. For example, through consistent efforts, they improved the energy efficiency of a listed building’s envelope by 25% — a signif­icant achievement in such a complex context.

A Sustainable Collab­o­ration Focused on the Future

The long-standing relationship between Rentes Genevoises and Signa-Terre is built on a delicate balance: the strategic vision and investment capacity of Rentes Genevoises paired with Signa-Terre’s technical expertise and strategic analysis to maximize the impact of these actions. Together, they have developed a holistic approach combining environ­mental perfor­mance, economic viability, and the antic­i­pation of future gener­a­tional needs. Their annual invest­ments of CHF 10 to 12 million for property mainte­nance and renovation aim not only to meet current standards but also to antic­ipate future legal and techno­logical devel­op­ments. This continuous trans­for­mation process integrates a long-term sustain­ability vision. Pierre Zumwald, CEO of Rentes Genevoises, remarks: “Our relationship has been built on dialogue over all these years since 2009. It’s a true success”
