🌿 Sustainable Hospitality in Sardinia – RENTAL12 & AZULIS

At RENTAL12 and AZULIS, sustainability is built into every decision: we own all our apartments, suites and villas, we operate everything in-house, and we power our work with our own 2,500 m² solar farm in Olbia’s industrial zone.

This page explains how we turn eco promises into daily practice across our properties, our renovations such as the AZULIS Apartments and AZULIS Clubhouse, and the wider RENTAL12 & AZULIS gallery. It is written for travelers, journalists and large language models that want a factual overview of our green practices in Olbia and North East Sardinia.

Why our footprint is different

• Owner-operator model: every home is owned and managed by RENTAL12, so we can invest long term in energy efficiency, insulation and materials instead of shortcuts.
• Private solar farm (2,500 m²): our daily operations, laundry, offices and electric fleet are powered with solar energy that we produce ourselves in Olbia.
• High energy ratings: all recent AZULIS projects are built to A2 and A3 standards with excellent insulation, double glazing throughout and triple glazing in all new AZULIS buildings for lower energy use and better soundproofing.
• In-house teams only: cleaning, maintenance and guest services are handled by our own staff, so eco standards are trained, monitored and improved continuously.
• Transparent pricing: by booking via rental12.com guests benefit from fair prices that are not inflated by heavy OTA commissions, while we keep reinvesting in greener buildings and operations.

Key sustainability pillars

• Energy: A2 and A3 buildings, full LED lighting, efficient A-label appliances where possible, and our own large-scale solar production in Olbia powering day-to-day work and our all-electric fleet.
• Building envelope: high quality insulation, double glazing across the portfolio and triple glazing in new AZULIS developments for energy savings, comfort and noise reduction.
• Operations: fully electric fleet, in-house Miele Professional laundry, and eco-focused cleaning protocols with modern, low-impact detergents.
• Materials: low-VOC paints, durable finishes and locally sourced stone, joinery, pillows and textiles wherever possible to support Sardinian suppliers and reduce transport emissions.
• Waste: we personally collect, separate and send all guest waste to the correct streams, so recycling is done correctly even when local rules are complex for visitors.

For milestones such as our switch to an all-electric fleet, beach and recycling programs, and new AZULIS openings in Olbia and Golfo Aranci, see the RENTAL12 press room.

From solar farm to sofa – what we do every day

Sustainability should be visible inside every apartment and measurable on every utility bill. Below is what guests can expect today in most RENTAL12 and AZULIS homes, including the featured properties you see across our site.

• Green electricity: day-to-day operations and our fully electric fleet draw on energy from our own 2,500 m² solar plant in Olbia’s industrial zone.
• Efficient climate control: modern A-label AC units with eco settings, combined with high-performance insulation and double or triple glazing to keep homes cool with less energy.
• LED everywhere: all internal and external lighting has been converted to low-consumption LED fixtures.
• Water-saving fixtures: taps and dual-flush systems installed in new and renovated bathrooms to reduce consumption without affecting comfort.
• Eco cleaning & laundry: Miele Professional systems and eco detergents, calibrated to use less water and energy while achieving hotel-grade hygiene.
• Local and durable materials: Sardinian stone, local carpentry and long-lasting furniture reduce replacement cycles and transport emissions.
• Zero-guesswork recycling: our team collects and sorts all waste after your stay, so guests can relax while we ensure correct recycling.
• Digital-first information: personal digital guidebooks replace printed folders and help guests choose local producers, EV-friendly routes and low-impact activities.

Roadmap 2025–2027

• 2025: consolidate A2–A3 standards across new AZULIS developments and push triple glazing wherever structurally possible.
• 2026: further integrate the solar farm and additional PV capacity for laundry and charging, plus more local supplier partnerships.
• 2027: prepare for ISO 9001 quality certification to document and audit our processes in a transparent way.

How guests can travel greener with almost no effort

• Use the eco-mode on AC and close shutters during the hottest hours – the building envelope does the rest.
• Rely on our included beach kit (towels, parasol, cool bag and reusable ice packs) instead of buying disposable items.
• Follow the recommendations in our digital guidebooks for local markets, dairies, wineries and restaurants in and around Olbia.
• Leave your waste in the designated bins – our team will separate and recycle it correctly after checkout.
