- The Carmen Hotel by sanzpont, a project inspired by the coral in the Caribbean Sea
The Carmen Hotel is located in a unique position on the seashore. This fact greatly influenced the architecture project, with a particular focus on sustainability, due to the climate and the location, to protect the basis of the tourist economy.
For the volume, the architects from sanzpont went for a modular structure, using a construction system based on frames, for simple, cost-effective completion. The architects used high-performance prefabricated panels for thermal insulation and acoustic comfort, assuring low energy consumption and comfortable interiors for guests.
The rectangular site posed its own challenge - the short end of the rectangle overlooks the sea while the longer side faces onto the street. The proposal by sanzpont involved rotating the building 30 degrees to give all the rooms an ocean view. The architects developed the hotel across three levels of rooms, in addition to a basement level with utilities, a ground ﬂoor with the reception and a restaurant, and an infinity rooftop pool on the third level.
The Carmen Hotel incorporates a series of passive design solutions to reduce the building’s environmental impact. The architects went with insulation materials that prevent solar gain, and also integrated triple-glazing filled with argon gas that has very low thermal conductivity. These options help to obtain a fully insulated system when air-conditioning is required. At the same time, the highly efficient use of cross-ventilation of natural air minimizes air-conditioning consumption. Knowing that the prevailing winds in the Caribbean come from the southeast and east, the team decided to turn the rooms 30 degrees to capture the wind and extract it through a duct in the corridor ceiling, creating natural ventilation in each space. Besides, every room in the hotel is fitted with motion detectors and door-and-window opening sensors to avoid wasting energy.
The architects analyzed the movement and angles of the sun with solar geometry, which allowed them to implement effective architectural shading. They positioned overhangs and lattices to prevent direct sunlight from penetrating into the interiors, and to block the south and west facades. And everything is based on the idea of the characteristic soft organic shapes of the Caribbean corals, making this hotel also stand out visually from the endless string of beachfront accommodation facilities.
