The Investment Corporation is steadily moving forward with conversion to LED (installation of LED lighting and lighting equipment with human-detecting sensors) in the common and private areas of all office properties it owns, with a target of 100% LED conversion by the close of the fiscal year ending in May 2026 (41st FP.) (Assuming this target is achieved, the estimated effect between the fiscal period ended May 2021 (31st FP) and the fiscal period ending May 2026 (41st FP) is forecast to be equivalent to an approximately 11% reduction in power and an approximately 4,700t reduction in CO2 emissions.)

Environmental Pollution Countermeasures

When acquiring new properties, the Investment Corporation strives to avoid risks by checking in advance for environmental and social risks to ensure there are no problems, including hazardous substances (PCB, asbestos, etc.) and soil contamination, in addition to conducting site inspections and surveys. If hazardous substances or the like are present at a property that it owns, it will implement appropriate countermeasures, management, and disposal in compliance with the laws and regulations.

Promoting Greening of Walls and Rooftops/Conserving Biodiversity

The Investment Corporation is promoting the greening of properties in its possession as part of its efforts to address climate change and biodiversity.
One of the properties owned by the Investment Corporation, Daiwa Azabu Terrace, is notable for its stylish design with greenery on multiple levels. The rooftop level and the roof areas of the third to sixth floors, which have a terraced structure due to height restrictions based on shadow control regulations, form a rooftop garden (approx. 1,523 ㎡) with a different concept on each level. With a planting plan that takes the ecosystem network into account by using many plants native to the region, it is a green office building that leverages the appeal of the rooftop garden while also addressing the conservation of biodiversity.
