GOOD CYCLE BUILDING 001 Asanuma Corporation Nagoya Branch Office Renovation by Nori Architects and Asanuma Corporation
The Asanuma Corporation is promoting its first flagship project, the GOOD CYCLE BUILDING, a project to renovate a 30-year-old building into an environmentally friendly building. The existing building frame was utilized and modified to increase accessibility to natural light and wind, and new materials were added as much as possible using natural materials such as earth and wood, enabling the building users to participate in the construction and maintenance process.
The Asanuma Corporation is promoting its first flagship project, the GOOD CYCLE BUILDING, a project to renovate a 30-year-old building into an environmentally friendly building. The existing building frame was utilized and modified to increase accessibility to natural light and wind, and new materials were added as much as possible using natural materials such as earth and wood, enabling the building users to participate in the construction and maintenance process.
Inside and outside the building, soil materials were used for floors, walls, ceilings, and furniture. Raw materials were obtained from leftover soil in Aichi Prefecture. As long as amateurs participate in the finishing process, such as making marks with their fingers or throwing soil, the wall will be expressed "naturally" through human movement. Aside from the fact that earthen walls are not impure (petroleum-derived materials and cement are sometimes added to improve durability), they can also be applied for painting in the future and eventually returned to nature. In addition to the interior and exterior of the building as well as for furniture, fittings, and products, Japanese cedar from the Yoshino forest in Nara, which Asanuma Corporation manages sustainably, wharvested.ed. To minimize the amount of scrap wood generated, the front façade is built from Yoshino cedar logs with the largest diameter from a single tree. Existing stones and other materials used in existing buildings were repurposed as interior surfaces. Others were crushed into small pieces and hardened with plaster to be used as furniture surfaces. Urban waste was also used as a resource. A surface material made of waste plastic flakes that have been crushed and hardened by heating has been used to cover existing furniture, and a knitted fabric made of recycled polyester yarn has been used to wrap existing furniture.
A building functions as a "material bank" and is a transit point in the flow of materials. To maximize the possibility of re-using materials, it is imperative to use natural materials in a way that allows them to be separated from artificial materials, in order to maximize their effectiveness, and eventually return them to the earth. It is necessary to process existing man-made materials so that new materials can be created, making the most of their characteristics. By creating a delightful environment connected to the changing nature of light, wind, soil, trees, and plants, this project attempts to reconstruct buildings as part of the new material flow in the city, and to reposition architecture in a cycle that is good for people and the earth.

REVZO Toranomon was designed to minimize waste generation in the architecture
Sustainable architecture is often referred to as green architecture or environmental architecture. To achieve minimal negative impacts to the ecosystem and the communities, architects must produce smart designs and use available technologies. Norihisa KAWASHIMA, Principal at Nori Architects, Senior Assistant Professor at Meiji University, and his team of architects have minimized the amount of waste generated from the construction of a new mid-scale rental office series to achieve sustainability.

Norihisa KAWASHIMA, Principal at Nori Architects, Senior Assistant Professor at Meiji University, and his team of architects have minimized the amount of waste generated from the construction of a new mid-scale rental office series to achieve sustainability.
In June 2020, the REVZO prototype has been completed at Toranomon, Tokyo, as part of a planned series by a Japanese real estate company. Through improving the physical and mental well-being of its occupants, and fostering a creative atmosphere, this office aims to foster a delightful environment where one can connect with the ever-changing "nature" around them. The core configuration includes two wide openings, with the street-facing side allowing natural light to penetrate fully into the 17-meter deep tenant workspace. The floors have operable windows to facilitate natural ventilation. There is a balcony with a planting strip along the street-facing side of the building. The planting strips will be filled with cherry blossoms, hydrangeas, and color-changing seasonal plants, as well as edible plants such as blueberries, lemons, and herbs, creating a place where tenants can observe seasonal changes and harvest them as well. In addition to providing footholds for plants, stainless steel mesh along the side of the balcony protects residents and objects from falling. An outdoor escape staircase is located at the end of a balcony, which can serve as an extension of the balcony. On one side of the building, air conditioners are located, blowing horizontally into the room, eliminating the need for ductwork from the ceiling. This allows for a high ceiling while keeping the floor-to-ceiling height low. In addition to reducing waste generated during construction, semi-skeletonized finishes also provide for immediate occupancy and reduced environmental impact.
The entrance is covered in a variety of wild vegetation, including red pine and agave. The arrangement makes seasonal changes visible to visitors and office workers alike. Plants are arranged and displayed on earthen walls, mirrors, and displays depicting images of nature throughout the lobby area. Displays of furniture creations are also on display. Due to the natural lighting and well-ventilated stairs, and art and speakers on every floor, one would prefer to take the staircase instead of taking the elevator. A communal lounge with high ceilings, decorated with wood, earth, and vegetation, can be found on the top floor. Labels on furniture and accessories indicate where they come from, creating an environment that demonstrates the craftsmanship put into the furniture.
