Longer Life Buildings

Standardization of 100 Year Buildings

The Company formulated the Hulic Guidelines for Longer Life Building (the Guidelines) in 2011 to standardize specifications for development and reconstruction projects. The Guidelines are composed of three ideas, 1) high earthquake resistance and high durability; 2) smoother updating and renewal; and 3) high serviceability. We use only high-grade building frames that ensure the buildings are durable and used safely for over 100 years as well as make it possible to modify layout or change of intended use to fit with diversifying work styles in the future and reform building exteriors. Furthermore, longer life buildings reduce waste generation and resources used for reconstruction by 50% or more, and reduce life cycle CO2 by 6% compared to the cases where buildings are conventionally reconstructed every 40 years (standard plans).
Based on this evaluation, we have introduced longer life designs as standard specifications in all development and reconstruction completed or under development since formulating the Guidelines in 2011.

Environmental Advantages of Longer Life Buildings

Hulic Guidelines for Longer Life Building

1 High earthquake-resistance and high durability

Structural frames shall be strong and solid so they can be safely used over 100 years.

  • We apply our internal earthquake-resistance standards where building performance can safeguard human life and enable continued use of the building with post-earthquake repair in the event of an earthquake with a seismic intensity of seven to all asset types of properties we develop or construct
  • Thoroughly control the quality of works by designating details of design conditions for concrete and construction materials

2 Smoother updating and renewal

We adopt a design capable of responding flexibly to future needs, and establish plans of updating and renewal without the need to make tenants move out.

  • Flexibly respond to future changes in use purposes and layout, with spare ceiling height room and floor loading capacity, as well as a flexible partition wall and a system ceiling.
  • Ensure the space to install spare pipes and equipment, etc. so as to continue business even during the period of works for updating and renewal.
  • Especially in commercial buildings, adopt the interchangeable facade system capable to meet the needs of the time, in order to avoid the building exterior to become obsolete.

3 Ease of maintenance

We formulate plans enabling timely and meticulous maintenance in order to keep sophisticated building specifications and optimal building functions constantly.

  • Use gondola for maintenance, including inspections of the building exterior.
  • Install an elevator reaching the rooftop to carry in materials there.

POINT1

Responding to future changes in purpose of use and layout

From a viewpoint of a long-term use for 100 years, it can be expected that the use of building will largely change, for example, from an office building to a store or from a store to a restaurant. By providing spare ceiling height room and floor loading capacity in advance, it is possible to respond easily to future changes in use purposes and layout, as well as for renewal.

Ceiling height: 2.8m or higher
Loading capacity: 500kg/m2 in general, 800kg/m2~1t/m2 in heavy duty zone
System ceiling: Responding to needs for smoother updating of facilities in the ceiling, ease of maintenance, and changeability of partitions between tenants.

POINT2

Replaceable facade systems

Especially for commercial buildings, the exterior appearance is important. This is because a stylish appearance at the forefront of the age would attract customers. Therefore, we have adopted a system in which the facade (front exterior of building) can be separated from the main structure to update the exterior design without any legal restraints. Hulic Ginza Sukiyabashi Building located in Ginza, a major commercial area in Japan, has adopted the characteristic facade design expressing the scenery of a waterfront with willow trees. The two-tier facade with casted aluminum in curved shape installed on the curtain wall is separate from the main body of the building.
As for office buildings, we intend to adopt a simple and calm design with an exterior appearance that can become harmonious with the surrounding landscape as time passes.
