Renewable energy will soon help power the operations of one of Glasgow's best-known city-centre hotels, following a rooftop solar panel installation project.

The Glasgow Marriott Hotel recently completed a multi-million pound refurbishment, and investment continues as work is currently underway to install a new solar panel system. Once operational, the 600 solar modules installed by Sustain Commercial Solar will generate clean electricity to support the hotel's day-to-day operations. The initiative will reduce its annual grid electricity demand by 11.4% and deliver a significant and measurable cut in operational carbon emissions of 35,812 kg per year.

The installation is the latest step in a wider sustainability programme for the four-star deluxe Glasgow Marriott Hotel. As one of the first hotels in the city to achieve Green Key certification—a leading international environmental benchmark for tourism businesses—the Glasgow Marriott has already demonstrated a strong commitment to environmental standards. The hotel has also secured Gold Certification from The PLEDGE™ on Food Waste, using Winnow AI technology to track food waste in real time and improve kitchen efficiency.

Further green initiatives introduced across the hotel include:

• EV charging points in the guest car park

• Motion-sensor lighting installed throughout the building

• Water-conserving fixtures in bathrooms and facilities

Complete removal of single-use plastics, including plastic straws and stirrers, from all hotel operations

The Glasgow Marriott also recently installed a voltage optimisation unit. This technology reduces and stabilises incoming grid voltage, which ultimately improves energy efficiency, decreases carbon emissions, and extends the lifespan of electrical equipment throughout the property.

Chris McGuinness, General Manager of the Glasgow Marriott Hotel, said: "Sustainability is something our guests increasingly expect from the places they choose to stay, and it is something we are taking very seriously as a business. Installing solar panels is a practical step towards reducing our environmental impact while continuing to deliver the high standards of hospitality we're known for and are proud to provide.

"Since the Marriott Hotel became a part of Glasgow's skyline 40 years ago, the city has continued to attract global conferences, major sporting competitions and culturally significant international exhibitions. It is important for hotels to play their part in supporting the city's reputation as a bustling, dynamic destination with plenty to offer, in a manner that sustainably supports the pursuit of further growth."

Situated in the city centre just off the M8, the award-winning Glasgow Marriott Hotel features over 300 bedrooms, extensive meeting facilities, and premium food, beverage, and leisure facilities.

The solar PV installation project is being delivered with the hotel's day-to-day operations fully protected throughout, ensuring no disruption to guests or staff during the installation process.

Nick Elbourne, Director at Sustain Commercial Solar, added: "The Glasgow Marriott presented a genuinely interesting installation. Working across mixed roof elevations in a live city-centre hotel environment requires careful planning and tight coordination with the operations team. The result is a high-performance system that will deliver clean energy to this building for decades, and a real statement of intent from a major hospitality brand."
