Green Key-awarded Grand Sirenis Punta Cana Resort in the Dominican Republic re-opened its doors one year ago after a thorough renovation, including the installation of the latest technologies.
Since air-conditioning and lighting are main sources of electricity consumption in the resort, LED has been installed all over the establishment as the source of lighting during the renovation. Moreover, a smart presence sensor system controls the lighting and the air-conditioning in the guest rooms shutting off all lights and returning to a pre-set comfort temperature of the air-conditioning system when finding the room empty. The sensors replace the key card and register presence when guests are entering the room. When registering presence, all lights that were on upon de client leaving the room turn back on automatically. The sensors also register when guests are opening the balcony door and the air-conditioning is turned off to avoid waste of energy and condensation.
