Our Group-wide Initiatives

Fundamental Approach

We are proactively working to reduce waste and water consumption in cooperation with tenants and building management companies toward realization of recycling society.
For developing and reconstructing buildings, we endeavor to reduce environmental impacts by promoting the 3R (reduce, reuse, and recycle) through the adoption of Longer Life Building designs that enable to reduce waste significantly and use resources effectively.

Resource-saving and Reduction of Waste in Buildings Owned by Hulic and Reconstruction of Buildings

Hulic Group has worked on reduction in the amount of waste disposal and water consumption in cooperation with tenants and building management companies. We install toilets that reuse water and various water conservation systems in many of our buildings. Water saving toilets and wash basins are standardized.

Amount of Waste Disposal at Hulic Group

We are constantly making efforts at buildings which our group company head offices occupy including hotels to reduce waste in order for building a material-recycling society.

  • *Figures marked withhave been assured by an independent assurance provider.
  • * The boundary is the buildings occupied by the head offices of Hulic and its Group companies. In FY2020, we calculated total waste disposal at certain properties in the boundary by using weight conversion factors based on actual measurements. As a result, we were able to improve the precision of the weight of the total waste disposal by 169 metric tons compared with the weight calculated by using the conventional weight conversion factors. The results increased from FY2018 as Porte Kanazawa, a large commercial building, has become subject to aggregation since.

Promotion of the 3R

Efforts to Reduce

Reduction of disposals from restaurants in our own brand hotels

We have materialized environmental advantages by making efforts to curb the amount of waste disposal and CO2 emissions during development, for example, by adopting longer life designs which can be in service for 100 years or longer as standard specifications(*) with an eye to saving resources. At hotels we own and manage (The Gate Hotel brand) are reducing the amount of garbage from their restaurants by biologically processing raw garbage.

*When building with longer life designs, the amounts of waste generated and resources used in reconstruction works can be reduced 50% or more, compared to the conventional case of reconstruction every 40 years (standard plans). Based on this evaluation, we have introduced longer life designs as standard specifications in all developments completed or under construction since 2011.

Reduction of plastic waste at head office building

In consideration of the seriousness of marine pollution caused by disposable plastic waste, the in-house canteen at the Hulic head office building has stopped use of disposable plastic beverage containers, straws, spoons and shopping bags. We are also actively encouraging employees to bring their own cups.

Efforts to Reuse

Recycling parts of underground building frames during reconstruction

In reconstruction works, we make various efforts for reducing wastes generated in demolition works including concrete debris. For example, underground building frames of existing buildings are used as retaining walls for the new building with new underground building frames installed inside. We make sure that adequate inspections are conducted to confirm the strength when building frames of existing buildings are recycled.
After considering impacts on neighboring areas of property, we introduced the PC method (described later) into the following projects:

  • Hulic Ginza Sukiyabashi Building
  • Hulic Head Office Building
  • Ochanomizu Sola City
  • Hulic Shinjuku Building

Book donation program

We launched the book donation program, which started based on suggestions from employees. In this program, we donate the proceeds from selling used books collected from group employees to the external used book dealer to Shanti Volunteer Association, which provides educational and cultural support to children in Asia. This activity contributes to reducing waste and helps to address the poverty issue.

Efforts to Recycle

As recycling efforts through daily business activities, we started to recycle used paper and printer toner cartridges. We will continue to work on those efforts to support achieving a recycling society.

Trends in the amount of recycled paper(*)

(Unit: kg)

Fiscal year FY2016 FY2017 FY2018 FY2019 FY2020
Recycled amount 9,400 11,365 13,125 14,540 15,600

* The scope is Hulic Head Office Building.

Prevention of Pollution

The Company considers that the minimization of environmental pollution due to business activities is indispensable to realize a recycling society. When planning buildings, we adopt construction methods to reduce pollutant emissions to the extent possible in cooperation with design and construction companies. In addition, we aggregate data on SOx, NOx, VOC, and hazardous waste generated in the development business to monitor the amounts generated, and we disclose the actual results .

Amount of emission of SOx, NOx and VOC from hazardous wastes

  FY2018 FY2019 FY2020
Number of properties 10 4 7
SOx emissions (kg) 1,620 60 142
NOx emissions (kg) 11,527 1,334 1,649
VOC emissions (kg) 157 124 0
  • *Figures are for developed and constructed buildings for which data were collected in each year.

Initiatives for Water

Initiatives to Reduce Water Consumption

Almost all water consumed in the Group are from the buildings owned or the buildings that we have offices, and the water flow starts from tap water and discharge it into sewers. To reduce the amount of water consumption in buildings owned by the Company, we have taken the initiative of introducing water-saving devices on water taps installed in the plumbing of existing buildings (saves water by approximately 40% per tap) to preserve water resource.

In addition, we are gradually upgrading the toilets in the buildings we own to ensure better plumbing while also changing to water-saving flush toilets and hand washers. The Company is also working to ensure the effective use of water resources by using rainwater to water the greenery and flush toilets for certain buildings. Note that Hulic does not operate business activities in high water stress area where demand for water is tight.

  • *The figure marked withhas been assured by an independent assurance provider.
  • *The boundary is properties with a total floor area of 3,000 m2 or more, excluding buildings where bank branch is the sole tenant, as well as sectional and shared ownership properties and real estate for sale. Please refer to page 19 for the number of target properties.

Adoption of the PC Method

From the standpoint of a business owner, we proactively adopt the PC method (*), which can significantly reduce the amount of waste generated during construction. This method, which can shorten a construction period and minimize impacts on surrounding environments during construction, is highly rated in terms of longer life service of buildings.

  • *PC (Precast Concrete) method: Precast panels produced at a plant under consistent quality control are carried to a worksite and assembled.

Effect of the PC Method

Benefits of Hybrid Fireproof Wooden Construction*

(Reducing environmental burdens)
  • Reduced-weight materials
    • -Rationalization of vehicles and heavy machinery in transportation and construction operations
    • -Reduction of CO2 emissions from transportation
  • Factory production reduces the amount of onsite work and eliminates onsite waste materials
  • Adoption of floor CLT eliminates need for scaffolding
(Benefits within construction activities)
  • Highly accurate pre-cut processing (machining) contributes to smooth assembly work
  • Convenience when fixing to other building materials with screws
  • Since structure is finished material, interior finishing costs are reduced
  • *Hybrid structure combining wooden and steel framework
