About Oak Konan Shinagawa Bilding sa Opisina

Ang Oak Konan Shinagawa usa ka 12-andana nga bilding sa opisina nga nahimutang duol sa pantalan sa Tokyo, Japan. Ang puti nga sama-sa-lattice nga panggawas nga bayanan usa ka gawas nga panit nga hinimo sa precast concrete nga nagsilbi isip estruktural nga bayanan ug himan sa pagsalipod sa adlaw. Inubanan sa steel nga konstruksyon sa core, kining hybrid nga estruktura nagmugna og espasyo sa opisina nga walay haligi nga nagtugot sa flexible nga mga layout. Ang precast nga mga haligi ug mga biga gihimo gawas sa lugar ug gipaubos ngadto sa ilang dapit gikan sa ibabaw, nga nagpasayon sa trabaho sa lugar. Ang panggawas nga mga bintana adunay mga yunit sa natural nga bentilasyon nga maablihan pinaagi sa matangtang nga hawiranan.

Unique Properties: The building is a mid-rise, 12-story office building located near the harbor in Shinagawa, Tokyo.
The distinctive, white lattice-like exterior frame is an outer shell made of precast concrete serving as
structural frame as well as sun-shading device. Combined with the steel construction of the core this
hybrid structure creates a column-free office space. The fusion of structure and finishing enhances high
buildability and sustainability.
Dimensions & Packaging: [Site area] 2,635.57m2
[Building area] 1,485.79m2
[Total floor area] 16,331.64m2
[Number of floors] 12 floors above ground, 1 floor below ground, tower building 1st floor
[Maximum Height] 56.76m
[Structure] steel construction, reinforced concrete construction in some parts

Production Technology: Supply and exhaust air for the office is provided on the east, west, north sides from equipment units (air supply
units and exhaust air units) built into the aluminum curtain wall inside the columns and beams.
By taking advantage of the depth (500mm) of the exterior shell structure and installing air intake and exhaust air
outlets on the same exterior wall surface, the amount of ductwork in the office ceiling was significantly reduced,
which also contributes to high buildability.
The deep structural frame also controls the amount of direct solar radiation and significantly reduces the heat loads.
Design Challenge: Labor shortage in the Japanese Construction Industry is a major challenge.
Although research into new technologies such as construction robots is progressing, there are still few examples of their use in actual construction sites.
One of the major themes of this project is high buildability.
We communicated with the construction staff to find a construction method that was easy to construct and of high quality.
At the same time, as architects, we had to keep creating new ideas for exterior and interior to added-value to the client.
Research: Labor shortage have recently become major challenges in the Japanese Construction Industry.
This building uses precast concrete columns and beams, which serve as both the structure and exterior finishing materials of the shell structure that characterizes the facade.The use of precast concrete elements fabricated off-site ensures high quality and accuracy.
In addition, the structural frame was designed without horizontal connection, which enables to simplify the site erection. Productivity on site has significantly improved by simply dropping columns and beams from above like building blocks.
Inspiration: Labor shortage have recently become major challenges in the Japanese Construction Industry.
Structural frame was designed without horizontal connection, which enables to simplify the site erection.
Productivity on site has significantly improved by simply dropping columns and beams from above like building blocks.
The design of the interior in many areas is based on a motif of vertical and
horizontal lines and grids inspired by the facade design.
Project Duration: The project started in September 2020 and finished in July 2022 in Tokyo, Japan.
Operation Flow: The column-free office space with a hybrid structure of a precast concrete outer frame and steel construction improves the flexibility of office layout and significantly enhances the convenience of users.
In addition, the exterior windows have natural ventilation window units that can be opened and closed freely by attaching a detachable handle, allowing for direct air intake.
