Angsana Quan Lan Ha Long Bay Hotel & Villas

EDGE Advanced

Angsana Quan Lan Ha Long Bay Hotel and Villas is a new resort on Quan Lan Island. The resort was designed to complement the natural beauty of the island.

The hotel utilizes resource-efficient design features and technologies to reduce its environmental impact and save on operating costs. LED lighting, external shading devices, and an energy-efficient air conditioning system reduce the building’s energy use, while low-flow showerheads and water-efficient plumbing fixtures reduce the building’s water use.

The Angsana Group of hotels and villas has been developed by Banyan Tree Holdings, a leading hospitality group in the region. By certifying its Quan Lan Ha Long Bay resort with EDGE, Banyan Tree is demonstrating its commitment to sustainable development.

Angsana Quan Lan Ha Long Bay Hotel and Villas has received an EDGE Advanced certificate from SGS Vietnam.
