Aiming to be a corporate group that generates happiness amongst urban residents and widely contributes to society
Corporate activities Sustainability are starting to have a greater impact on stakeholders than ever before. The Sankei Building Group is keenly aware of its social responsibilities and corporate role of ensuring that sustainable development can be achieved. The group aims to fulfill this role with all stakeholders.
Introducing an example of a real-estate development implemented with the corporate philosophy "Environmental Coexistence"

Coexistence with the environment

The Nishiumeta Sankei Building
(Hotel Intergate Osaka Umeda) 
wins the FY2021 Osaka
Environmentally Friendly Architecture Award

The Nishiumeta Sankei Building (Hotel Intergate Osaka Umeda), owned by Sankei Building, has won the FY2021 Osaka Environmentally Friendly Architecture Award Commercial Facilities and Others Divisions Award.
In particular, it was highly evaluated for its contribution to reducing the heat island effect through the use of a water-cooled multi-unit air conditioning system with a large temperature differential water supply and exhaust heat recovery, and for its facilities such as air conditioning and lighting control tailored to biological rhythms, providing an indoor space that is friendly to both people and the environment.


Solar power generation

A solar power generation system can be installed to enable the facility to use the generated electricity for its own use, thereby helping to reduce environmental impact,

Use of LED lighting throughout the building

LED lighting will be installed to reduce energy consumption throughout the building.

Energy saving using sandwich panels

We aim to reduce energy consumption by adopting sandwich panels with excellent heat insulation.

In August 2022, SANKEILOGI Atsugi acquired the highest rank of 5 stars and "Nearly ZEB (*1)" under the Building Energy Efficiency Labeling System "BELS (*2)".

*1 BELS is a system in which a third-party organization accurately evaluates and displays the energy-saving performance of buildings based on the guidelines established by the Ministry of Land, Infrastructure, Transport and Tourism. Evaluation is displayed in five stages (★~★★★★★).
*2 ZEB is an abbreviation for "Net Zero Energy Building," and refers to a building that aims to achieve zero annual primary energy balance while maintaining a comfortable indoor environment. In the BELS evaluation, ZEB is displayed in four stages: "ZEB," "Nearly ZEB," "ZEB Ready," and "ZEB Oriented."

Contribution to the local community

Involvement in traditional events

Hotel Intergate Kyoto Shijo Shinmachi

Hotel Intergate Kyoto Shijo Shinmachi participates in the Gion Festival. We participate in and seek to experience local traditional events as a member of the community. This gives us a deeper understanding of the events and fuels our efforts to preserve them.

Hotel Intergate Hiroshima

Hotel Intergate Hiroshima invited Hiroshima Kagura performers to exhibit the traditional local performing art at an event to commemorate our one-year anniversary. The troupe performed the celebratory dance “Ebisu” and the popular dramatization of “Yamata no Orochi” to the delight of our guests, who applauded the program as a wonderful memory of their trip to Hiroshima. We intend to continue using the hotel to host similar events and spread the word about captivating aspects of the local area.

Participation in “Online Lantern Floating – Messages in Lanterns”

The project “Online Lantern Floating -Messages in Lanterns-," which has been ongoing since 2015, is led by "Third Generation Thinking of Hiroshima" exhibition creators in their 30s. Lanterns filled with everyone's hopes and wishes can be sent down the river in an online virtual space, and messages sent from all over the world via the Internet will be projected on signage in Hiroshima's facilities and throughout the city. At Hotel Intergate Hiroshima, the event was projected on the digital signage in the elevator hall on the 1st floor and on the projector in front of the elevator on the 14th floor.

Creating customer value

「Hommachi Sankei Building」

Reducing the heat island effect and achieving better air conditioning efficiency

We opted for a water-cooled/water-source heat pump multi-unit air conditioning system that releases the latent heat of vaporization from the cooling towers in order to limit the release of sensible heat and help reduce the heat island effect. We also paired the system with water-cooled heat pump water heaters for the restroom sinks to achieve better air conditioning efficiency than heat recovery. With GHP chillers and other devices drawing from three different heat sources, our system offers consistent air conditioning operation, making it possible to maintain comfortable temperatures in the offices and reduce excess energy loads.

Ministry of Land, Infrastructure, Transport and Tourism (MLIT)
Selected as a Leading Project for Sustainable Buildings

The MLIT selected our project as a Leading Project for Sustainable Buildings for its groundbreaking ability to reduce CO2.


LEFOND PROGRES SHIBUYA HILLTOP, which was completed in Aobadai, Meguro-ku, will use the homehub app and smart locks of the bitlock series to enable seamless use between tenants. "bitlock MINI" and "bitreader+" are installed in each dwelling unit and common areas, and you can use the key of each dwelling unit, rooftop terrace, fitness room, large laundry, etc. with a single smartphone that has downloaded the "homehub" app. A face recognition system is also installed at the entrance of the house. By registering facial information on this application, the automatic door of the house entrance can be unlocked without using a key, and the elevator will land on the floor where the room is located. You can use your face as a key to pass through security. In addition, by linking each tenant, including the workplace, with the "homehub" app, it is possible to make reservations for each incidental facility, avoiding concentrated use of the facility and using it conveniently and with peace of mind.


With LEFOND PROGRES, a series of rental residence buildings being developed mainly in central Tokyo, we are working to create spaces that exude the sophistication and comfort of urban living. In the past, the characteristics of Japan’s housing units made remote working difficult, but we have solved this problem by setting up a workspace in the common area that tenants can use. We have also taken into consideration safety in city life by installing a full security system with security cameras and auto locks, as well as adopting an interior corridor layout designed to protect privacy.
