In recent years, energy conservation and carbon reduction have become central themes in global environmental discussions, and the hospitality industry is increasingly embracing eco-friendly architectural designs. Among these innovations, the Itomachi Hotel 0, designed by Kengo Kuma Architects, stands out as Japan's first zero-energy hotel, setting a new standard for sustainability in the country.
Located in Saijo City, Ehime Prefecture, this hotel seamlessly integrates with the surrounding natural landscape and harnesses the region's abundant resources, revitalizing the local community. The hotel comprises three distinct structures: a two-story Reception Café building, the main Hotel building, and a standalone Villa featuring an outdoor hot spring. In total, Itomachi Hotel 0 offers 57 guest rooms, including 50 rooms in four different configurations within the Hotel and 7 Villa rooms equipped with outdoor baths.
The architecture showcases a continuous, segmented wooden roof that echoes the majestic peaks of Mount Ishizuchi, while a central courtyard with a fountain symbolizes Saijo City's natural spring, "Ueki." This design creates a garden-like atmosphere that warmly welcomes visitors. To achieve its zero-energy goal, the hotel is outfitted with high-performance double-glazed windows, energy-efficient systems, and solar panels on the roof, enabling it to generate its own energy. As a result, Itomachi Hotel 0 has received the Zero Carbon Emission Building (ZEB) certification from Japan's Ministry of the Environment, solidifying its status as an environmental benchmark.
In terms of interior and landscape design, Dugout Architects drew inspiration from the local natural spring "Ueki" and Iyo granite, incorporating wooden elements to create soft, light tones that harmonize the indoor atmosphere with the outdoor scenery. The hotel's restaurant and café prioritize healthful dining by utilizing seasonal vegetables and fruits from Ehime Prefecture, aligned with the nutritional standards set by the Ministry of Health, Labour and Welfare. This approach allows guests to engage their senses with the local culture and cuisine.
The establishment of Itomachi Hotel 0 highlights the visibility of natural wooden materials, which are inherently carbon-negative. Wood can sequester carbon throughout its lifecycle, whereas the production of steel and concrete generates substantial carbon emissions, exacerbating global warming. Wooden structures require less energy for heating and cooling compared to concrete and steel, and they are biodegradable, allowing for material recycling and reducing waste. Itomachi Hotel 0 injects new green vitality into global environmental protection and calls for more industries to embrace sustainable development.
