Making Waves

A floating hotel that operates on tidal energy

“Enabling travellers to challenge themselves and to engage with conservation efforts, positively contributing to protecting ecosystems, will be a transformational travel experience. This could mean anything from offering an off-the-grid meditation retreat to facilitating volunteer work with non-profit organisations.”

Hotels have long been a metaphor for modernity, a bastion for unique experiences in the tourism and hospitality industry. How might architecture be used to change the hotel typology from becoming redundant?

The lighthouse hotel sits on a tension leg platform which works in the same way as a taut, moored buoy.

Reinvention is imminent for hotels to stay ahead of the game. Forward thinking architect Margot Krasojević believes a cross-programmatic approach will ensure that sustainability and renewable energy remain at the forefront of design criteria and programs. Hotels frequently innovate, and they can accommodate experimental design approaches catering to individuals who want to experience a unique getaway.

The tethered buoyant structure is a large, semi-submersible floating vessel, which uses a heavy gravity vacuum anchor that fastens it to the seabed. The tension force is maintained in these vertical cables by adjusting the buoyancy of the floating platform, ensuring positive tension at all times.
The lantern room, located at the top of the hotel, is revealed when the elevations lower during storms.

Krasojević envisions the Lighthouse hotel to be located off the South Korean coastline; offering opportunities for guests to engage with biodiversity and renewable energy.

“Enabling travellers to challenge themselves and to engage with conservation efforts, positively contributing to protecting ecosystems, will be a transformational travel experience. This could mean anything from offering an off-the-grid meditation retreat to facilitating volunteer work with non-profit organisations,” says Krasojević.

The structure utilises an existing oil rig, using the current platform for structural support onto which the offshore hotel is designed. Guests would access the accommodation by boat from the coast, making for a unique travel experience.

Futuristic & Green Design

The lighthouse hotel design is made up of three main sections: the guest rooms, the lobby and various social areas. The lantern room, which is at the top of the hotel will have a Fresnel glass lantern that projects light rays out to the sea. The refracted light will also beam through the interior of the hotel, creating a vibrant, light-filled atmosphere.The hotel’s design will be comprised of multiple flowing volumes made out of layered aluminum surfaces and a series of partly inflated membrane sections. These materials were chosen for not only their durability, but also their light weight. In case of emergency or rogue waves, the airlock sections split apart and float.Wrapped around the structure’s main core, a number of flip wing turbines will harvest the tidal power. As seawater crashes over surfaces, the turbines will pivot in accordance with the wind and wave motion, converting kinetic water energy into electrical energy.According to the architect, the turbines will generate enough clean energy to run the hotel and the structure’s desalination filters. Any surplus energy will be stored. The process also aims to reduce water consumption by storing rainwater, desalinating seawater, implementing grey-water systems and reclaiming water.

Water Levels

A primary concern with this design approach is the different heights of the water reservoirs, which requires water to be pumped into the elevated reservoirs during periods of low demand, to be released for generation when demand is high or system generation is low, thus reducing the overall process efficiency because of this energy consumption.On the other hand, the most significant factor that determines new technology is whether it effectively addresses the energy production output vs the energy input for a sufficient amount of energy produced.As with all technological applications, these designs need to be tested in order to recalibrate them to be a more energy efficient and comprehensible presence in design.

The Fresnel glass lantern light projects out over the entire area, creating an illuminated glass canopy lobby. The refracted light intensifies as it beams through and out into its surroundings, blurring the edges between interior and exterior space.
