By nature, Hotels tend to be energy inefficient as they often maximize views at the expense of solar exposure. They also tend to have high cooling loads — rooms need to be ready to go at any moment for potential guests, so they are often cooled even when no when is there. RAU and Powerhouse Company want to change that with a more efficient hotel that still provides luxurious views and a comfortable climate. H2Otel, which is situated along the Amstel river, is a carbon neutral, net-zero hotel for a modern world that harnesses solar passive design to minimize heat gain in the rooms.
A creative arrangement of wooden lamellas on the building’s facade protects it from overheating, but still provides the wonderful views coveted in high-rise hotels. The interval of lamellas spreads out towards the northern facade, allowing more lighting and views of Amsterdam below. The edges of the wooden façade panels are clad with copper, reflecting light into the rooms and creating the ‘golden glow’ known from the paintings of the Dutch masters.
Besides the innovative facade, the highly energy efficient building is centered around the use of water and oxy-hydrogen generators for heating, cooling, cooking and the generation of electricity. Additionally, rooms are monitored closely with an adaptive, sensor-based climate system that can be adjusted to accommodate the number of people in a room — if no one is present the air conditioning is shut off completely. This climate system helps to cut the building’s energy consumption by approximately 40%.
Besides the energy-efficient design, the hotel’s materials were chosen for their environmental friendliness and are either biodegradable or can be reused without loss of quality. The wooden lamellas are made from thermally-treated softwood. The project is currently on display at the National Design Triennial ‘Why Design Now?’ at the Cooper Hewitt National Design Museum in New York.
