The Abu Dhabi Tourism Authority (ADTA) said it has begun piloting its green hotel guidelines across four properties which are in the early design stage. “This is the first government green hotel design guidelines for new hotels and is based on Abu Dhabi’s Estidama Pearl Rating Scheme, which is a green building rating system for all new buildings in the emirate,” explained Nasser Al Reyami, Tourism Standards Director, ADTA. “By the middle of 2011, Abu Dhabi’s hotels and hotel apartments will have a green rating included in their star rating.” Al Reyami said the guidelines are being piloted across two, four-star and two, five-star hotels representing a mix of resorts and down-town urban properties.
