Energy consumption intensity and GHG emission intensity are calculated by dividing total electricity usage and CO2 emissions by intensity denominator (gross floor area (㎡)). |
Environment-friendly Initiatives
DHR implements the following environment-friendly measures for its properties.
■Energy saving measures
- LED lighting
- Slope to upper floor
- Daylighting through large windows
■Greening and countermeasures against heat island effect
- Large green area
- Rooftop greening
- Exterior greening/
water-permeable paving
■Promotion of green leases
Aiming to improve the environmental performance of portfolio assets through a collaborative effort with tenants, DHR is promoting green leases.
In a green lease agreement, the building owner and the tenants jointly cooperate by proactively entering into agreements and memorandums of understanding regarding the reduction of the environmental burden of the property, such as through energy savings, and improvement of the workplace environment, and by putting the details of these undertakings into practice.
| Number of properties with green lease agreements | Ratio of green lease agreements | |
|---|---|---|
| Green lease agreements | 28 properties | 25.0% |
(Notes)
| 1. | Contract status is stated as of March 31, 2019. |
|---|---|
| 2. | Ratio of green lease agreements = total gross floor area of properties under green lease agreements / total gross floor area of overall portfolio (Excluding the properties where only land is owned and Shibaura Island Bloom Tower.) |
| 3. | Gross floor area is based on the area listed on the inspection certificate of each property. |
| 4. | Ratio of green lease agreements shown is rounded to the nearest tenth. |
■Installation of solar power generation systems
As of March 31, 2019
| Number of properties | Power generated in FY ended Mar. 2019 |
|
|---|---|---|
| Properties with solar power generation facilities | 15 properties | 13,815 MWh |
| (Note) | The figure for the power generated includes only the properties for which data was obtainable among those with solar power generation facilities installed. |

■Effective use of water resources
After the acquisition by DHR, construction work was carried out to change the water used at the large-scale commercial complex, “ACROSSMALL Shinkamagaya,” from being supplied by a public water system to ground water due to the surrounding foundation being stable as well as the water being plentiful and of good quality.
- ACROSSMALL Shinkamagaya
■Supply chain management
The Asset Manager has established the criteria for selecting property management (PM) companies and evaluates all PM companies annually. Its evaluations cover a system for sustainability initiatives in addition to property management, property engineering management, leasing and other capabilities.
To achieve the energy reduction targets for properties owned by DHR, the Asset Manager will continue to promote measures to reduce environmental burden in cooperation with PM companies, building management (BM) companies and other suppliers.
■Management of multi-use properties
Capitalizing on its status as a diversified REIT, DHR also owns multi-use properties. DHR believes multi-use properties help to reduce environmental burden and contribute to revitalizing neighborhoods and communities through such means as reducing travel distances between workplaces, shopping and other popular destinations.
- Naha Shin-Toshin Center Building
(Daiwa Roynet Hotel Naha-Omoromachi)
(Office/Hotel/Retail)
- Qiz Ebisu
(Residential/Retail)
■Acquisition of environment-friendly properties
The large-scale commercial complex “iias Tsukuba” was selected as an exceptional example in the “Commercial Facilities and Accommodations Category” of the “Energy-Efficient Lighting Design Awards 2012,” sponsored by the Ministry of the Environment, due to the work they underwent to change to LED lighting after opening in October 2008.
- Interior walkways lit by LED lighting
(1) Energy saving and minimum maintenance realized through full scale introduction of LED lighting
Electricity consumed was reduced by approximately 68% compared to the fluorescent lighting originally installed, since lights of areas such as interior walkways and parking structures, outdoor signs, the workspaces other than the sales floors, and restrooms were all changed to LED lighting.
Compared to fluorescent and incandescent lighting, LED lighting gives off less heat, helping to suppress rising room temperatures, which also contributes to saving energy on air conditioning.
Furthermore, consideration is also given to the maintenance aspect by using the suitable LED lights in each place, such as adopting long-lasting kinds of LED lights in outdoor signs installed on the top of the buildings where changing lights is difficult.
(2) Lighting design conscious of the brightness of the space
Warm white lights are used for indoor lighting to produce a warm and relaxed atmosphere. Furthermore, our lighting design realizes energy conservation while ensuring brightness and safety such as by reconsidering illuminance levels for interior walkways and giving consideration to light leakage from shops and shop sign illumination.
These lighting designs create pleasant shopping spaces while making each shop’s display stand out. As a result, they provide a high level of satisfaction not only for customers but also for each shop.
About the “Energy-Efficient Lighting Design Awards”
Sponsored by the Ministry of the Environment, this award aims to spread “new energy-efficient lighting designs” that create attractive spaces while achieving excellent energy saving results, and to contribute to limiting peak demand of power consumption. The evaluation covers: (1) the results of installing energy saving lighting (2) design, innovation, creativity, and comfort (3) reproducibility, ability to contribute to the region, and autonomy as a model and (4) practicality, economic efficiency, etc.
Furthermore, installation of solar power generation facilities and wall greening took place at this property, and going forward, DHR is promoting acquisition of environment-friendly properties.
- Solar power generation facilities
- Wall greening
■Pollution prevention
Before adding any property to its portfolio, DHR shall conduct detailed environmental due diligence on the matters listed below. During the due diligence process, DHR comprehensively assesses the property’s investment value, weighing its impact on DHR’s overall portfolio, contribution to expected increase in value and other relevant considerations while consulting a fair real-estate appraisal by a third party with sufficient skill and experience in due diligence studies.
a. Geology and ground, buried objects, soil contamination, etc.
b. Status with respect to hazardous substances (asbestos, PCBs, etc.)
■Long-term environmental vision of “Challenge ZERO 2055”
