RAU and Powerhouse Company developed H2Otel, a luxurious and completely sustainable hotel for Amsterdam, The Netherlands. The project, a prototype for luxury hotel typologies, is shown at the National Design Triennial ‘Why Design Now?’ at the Cooper Hewitt National Design Museum in New York.
How to make a hotel tower more sustainable? As a typology, the modern hotel is at odds with the concept of sustainability. Most of the time they are empty and unused, yet they have to be fully accessible, comfortable and pleasurable all the time. Guests usually enter their rooms in the evening. Large glass planes provide stunning views but also heat up the rooms when no one is there. The biggest energy consumer in hotels is usually the cooling system. So, why are the facades of most highrises the same on all sides, despite their different exposure to sunlight? Apart from that, modern hotels are increasingly build according to global formulas in brownfield locations. How do we create a local sense of place while using the particular efficiency if the hotel typology?
Water is an important theme of the H2Otel. Situated alongside the Amstel river, the hotel is overlooking the historic center with its numerous canals, the docks on both banks of the River IJ and, on a clear day, the North Sea. But the name, H2Otel, does not only refer to its scenic views. Water is the building’s main carrier of energy. Through oxy-hydrogen generators water can be used for heating, cooling, cooking and the generation of electricity.
Fluctuating occupancy rates are an obstacle in reaching efficient climate control, especially in large hotels. In order to improve efficiency, an adaptive, sensor-based climate system monitors and controls the indoor climate in real time and for each room individually. It recognizes the number of occupants in a room and adjusts the level of conditioning accordingly. Conditioning is automatically switched off in empty rooms. This climate system helps to save approximately 40% of the building’s energy consumption.
While innovative technology is an important asset in achieving energy efficiency and carbon neutrality, inventive design solutions make a crucial difference in keeping the building’s demand for energy at a minimum in the first place.
