New London hotel, hub by Premier Inn Covent Garden, was rated BREEAM Outstanding based on its design, Whitbread has revealed.
It's the first time this Outstanding environmental assessment has been given to a UK hotel.
In the coming weeks, the hotel will get a Post-Construction BREEAM review, which will reveal the building's final certification.
"I’d like to offer my congratulations to Whitbread. This is a real achievement at the hub by Premier Inn, Covent Garden," said BREEAM director, Gavin Dunn.
"It shows a strong commitment to innovation and sustainability and as the first Outstanding rated hotel in the UK provides an exemplar for the industry as a whole."
BREEAM is an environmental ratings initiative used by buildings around the world.
Whitbread has spent over £30 million building the hub Covent Garden venue, and it can be found on St Martins Lane.
The venue has cutting edge energy saving, cooling and heating tech as part of its design.
Whitbread Hotels and Restaurants director of CSR, Simon Ewins, said that getting the top BREEAM rating ever seen for a UK hotel represents "a real step-change for the hospitality industry".
He said the rating shows that even when guests are using a lot of energy and water, companies are able to have sustainability as a priority, as well as great service.
Those in hotel jobs at hub Covent Garden are given training about water and energy sustainability.
Other environmentally friendly moves include LED lighting and the fact that rooms use variable refrigerant flow temperature control, which leads to lower carbon emissions than gas boilers and traditional chillers would, Whitbread reports.
Whitbread's committed pipeline includes 13 hub venues, all of them in London and Edinburgh.
The Covent Garden branch is the only one which has opened so far.
