A new prototype for a hotel that is powered by water has been designed by architecture firms RAU and Powerhouse Company – based in the Netherlands. Called the H2Otel, this could be the beginning of a new type of hotel that uses water in oxy-hydrogen generators for the hotel’s cooling, heating, cooking and power generation.
The prototype is for a luxury hotel that boasts of being highly efficient as well. Apart from using water for all the functions mentioned above, the hotel also uses a lot of other techniques to maximize energy efficiency – including passive design, advanced climate control systems and smart fixtures and appliances.
In the hotel industry, it is generally the rule that energy efficiency is always considered to be secondary to ensuring a good view from the rooms. Also, a certain number of rooms are generally kept ready for the eventuality that gests may arrive. This leads to a lot of energy wastage, which has come to be considered as an unavoidable hazard in the hospitality business. This is precisely what the designers of the H2Otel wish to change.
Situated along the Amstel river, the new prototype has been designed without compromising on view availability at the site, and has incorporated solar passive design to ensure that the rooms are not heated up by the sun, thereby reducing the need to cool them again. The protection from overheating is provided by the wooden lamella arrangement that runs all along the façade of the hotel, without blocking the view at any point. The edges of the lamella are tinged with copper, which ensures that the sunlight that is reflected back into the room is a soft sunny glow. The corners of the hotel are rounded to give protection from sound and wind and add to its compactness. The tower also rotates slowly to ensure none of the rooms miss out on the view.
