Section 1. Creating New Urban Spaces

On the basis of this mindset, Daibiru has established plans to invest more than 10 billion yen over the next 10 years to upgrade the Shin-Daibiru Building and Midosuji Daibiru Building in Osaka and the Yaesu Daibiru Building in Tokyo, all of which were 25–35 years old.

The renovation plans were carried out through the cooperation of tenants on the basis of the following four principles: meeting tenant needs to achieve a high level of appreciation, adopting the latest, most reliable, and most durable equipment, conserving energy, and reducing maintenance labor.

The Yaesu Daibiru Building, which had been completed in 1967, had been in operation for 26 years and was in need of equipment upgrades, so the decision was made to renovate the building. Upgrades to the electrical equipment, air conditioning system, and common areas began in January 1994, and the renovations were completed in September 2001. Renovations of the Midosuji Daibiru Building began in August 1994 and were completed in March 1999. They included upgrades to the electrical, air conditioning, and sanitation equipment as well as renovation of the ceilings and windows of the rental offices on floors three through eight. The renovation of the Shin-Daibiru Building was a major upgrade project that began in 1997 and lasted six years. This is because the Shin-Daibiru Building was much larger than the Yaesu Daibiru Building and Midosuji Daibiru Building. The flooring of the rental offices was changed raised access flooring. The ceilings were upgraded to sound-absorbing mineral wool, the electrical and air conditioning equipment were replaced, and the entrance and other common areas were renovated. These renovations were completed in 2003.
