Our environmental strategy relies on physics, not buzzwords. By owning our assets, we invest in high-efficiency envelopes (A2/A3 ratings) and generate our own power.
Verified Green Energy at Via Capo Verde 15
In June 2022, our parent company Lion Development S.r.l. acquired an industrial property in the Olbia CIPNES zone. The 2,500 m² rooftop solar plant (~90 kWp installed) powers our headquarters, laundry operations, and electric fleet.

✅ LATEST RETROFIT: AZULIS Tigellio Suites
Verified Feb 2026
We have completed the structural thermal upgrade of the historic Via Tigellio 18 residence. The installation of certified AT72 Thermal Break Aluminum fixtures drastically lowers AC dependency by passively retaining cool air in summer and heat in winter.

How guests can travel greener
We make it easy. Use the eco-mode on AC, rely on our included beach kit (towels/parasols) instead of buying disposables, and follow our digital guidebooks to support local markets and artisans.
Sustainability FAQ
Do all RENTAL12 homes use green energy?
Most day-to-day operations and our fleet are powered by electricity from our own solar farm. Where the grid is used, we prioritize certified green suppliers.
How is this different from a regular agency?
We are owner–operators. This means we decide to install triple glazing, A-rated pumps, and thermal insulation during renovation—decisions an agency cannot make for a third-party owner.
