The Nomura Real Estate Group uses energy and natural resources in the course of conducting business activities, and we are well aware that the substantial impact of climate change on business continuity is a major management issue.
Stricter environment regulations and increased natural disasters resulting from climate change will impede the continuation of business and lead to risks of higher material procurement costs and construction expenses. Moreover, it is possible that operating costs including electricity fees and insurance premiums will increase, with major impacts on customers including residents and tenant companies.
Based on this understanding, the Group is working with stakeholders including suppliers such as design and construction companies as well as customers to carry out low-carbon and energy-saving measures and promote efficient energy use and renewable energy utilization.
In addition, we are creating added-value business and contributing to the creation of sustainable societies by providing products and services in response to these issues.
Nomura Real Estate Holdings’ executive vice president and Group COO has been made responsible for these issues for the Group, and the entire Group is working together to address climate change.
In addition, the CSR Committee, which comprises Nomura Real Estate Holdings and Group company directors and others and is chaired by the Nomura Real Estate Holdings executive vice president, deliberates on and decides related policies and action plans.Starting in fiscal 2018, climate change targets were set, and the Committee is monitoring progress.
The Group has set the following three targets to address climate change.
When developing real estate, the Group confirms hazard maps and implements localized severe rain and flooding countermeasures in accordance with quality manuals.
We also take measures to minimize damage and ensure the safety and security of customers during disasters in accordance with business continuity plans (BCP).
We attach hazard maps to the Disclosure statement provided to housing purchasers.
The Group is developing net zero energy homes (ZEH*) in condominiums from the perspective of comprehensive environment impact reduction.
* Homes designed to achieve a net zero annual primary energy consumption by greatly improving the insulation performance of the building envelope, installing highly efficient facilities and equipment to maintain the quality of the indoor environment, while substantially reducing energy consumption and then introducing renewable energy.
When developing housing, office buildings, retail facilities, logistics facilities, and so on, the Group provides products and services that address climate change in accordance with the Design and Construction Standards and the Quality Manual.
Thermal insulation performance rating: level 4* (the highest level), double-glazed windows (end-panel eco-glass), LED lighting fixtures, and other features are set as standard specifications for PROUD condominiums.
With the aim of enhancing environmental performance, we prepared Environmental Assessment and Challenge Sheets with environmental performance assessment points for thermal insulation and shielding, energy efficiency, use of natural energy, and other factors. When planning and designing products, checks are made mandatory to ensure that performance exceeds internal criteria on these points.
* Thermal insulation performance rating: A housing performance evaluation system pursuant to the Housing Quality Assurance Act. Levels indicate performance in the thermal environment.
To reduce the use of ozone layer depleting chlorofluorocarbons, the Group established a quality manual that requires the use of chlorofluorocarbon-free insulation and air conditioner refrigerants.
Construction partners are also required to submit a Quality Control Check Sheet during construction to confirm that only chlorofluorocarbon-free materials are used.
At PROUD condominiums, the Group provides the enecoQ energy management system, which uses a service for purchasing high-voltage electric power for entire buildings and information and communications technologies (ICT) to curtail peak electric power consumption.
We also established NF Power Service Co., Ltd. as a group electric power procurement company, and use the demand forecasting models developed for the enecoQ service to efficiently procure electric power.
The Group is undertaking business intended to save energy and create a low-carbon society, and is pursuing the acquisition of environmental certifications.
The Nihonbashi Muromachi Nomura Building (located in Chuo-ku, Tokyo), developed by the Group, was certified as a Top-Level Office under the Tokyo Metropolitan Environmental Security Ordinance.
The PROUD Tsunashima SST (located in Yokohama City, Kanagawa Prefecture), a condominium developed by the Group, acquired LEED Gold certification and CASBEE Yokohama S rank (self-assessment) for its initiatives to reduce carbon and save energy.
The Yokohama Nomura Building (located in Yokohama City, Kanagawa Prefecture), which was developed by the Group, received LEED CS certification (Gold), CASBEE NC certification (S rank), and SEGES certification.
*1 Generators that can generate electric power using medium-pressure gas and oil.Such generators have higher reliability during emergencies compared to conventional generators.
*2 A system that uses waste heat produced during gas electric power generation as a heat source for building air conditioning.Such systems offer outstanding energy-saving performance and can operate partial air-conditioning functions even during power outages.
A cogeneration system
Nomura Real Estate Development won the Yokohama Global Warming Countermeasures Prize of the 25th Yokohama Environmental Activities Award for undertaking business with outstanding global warming countermeasures.
The Group is using the roofs of Landport logistics facilities to operate a solar power generation business.
As of March 2018, solar panels were installed on a total of 12 buildings with annual output of 11.55 million kWh.
The Group purchases green electric power.In fiscal 2017, the Nihonbashi Muromachi Nomura building (located in Chuo-ku, Tokyo) purchased 1 million kWh of power over the year.
The Group helps condominium residents and tenant companies to save energy.
For tenant companies, we provide systems that calculate total energy consumption and monitoring systems that make it possible to see the amount of energy used, encouraging energy savings. For condominium residents, we save energy using the enecoQ system, provide low-cost electric power, and provide eco-information via a member newsletter.
Fiscal 2017 performance against the set targets was as set forth below.
