Backed by the idea of "Communities grow," urban development in Harumi is pursued with operation and management of the area after completion incorporated into the idea formulated in the planning and design stages. The environment is a very important issue that modern society should tackle seriously and sincerely. The environment was taken into account from the very beginning of Harumi Triton Square's development in order to realize creation of an environmentally friendly community. With our environmental efforts still a top priority, we endeavor to take every action possible from various viewpoints toward environmental friendliness based on the idea that "Ecology is economy." "Our job is to keep the Earth for the future." We are always committed to the principle of active and brave tackling of the environmental issue.

4 Environment Incorporated into Planning Stage of Development Formerly the Harumi 1-chome area was a mixture of apartment buildings and warehouses constructed in the 1950s to the 60s. "Association to Make Harumi Better" was born in 1984 in response to an increasing need for reconstruction of the apartment buildings and a growing demand for better land use. In 1986, the Harumi Island Plan was announced. Urban redevelopment of the 1-chome area then started to "get the ball rolling" for the Harumi Island Plan. April 2001 saw the grand opening of Harumi Triton Square.

5 Harumi Avenue Town with Clear Zoning for User Friendliness The theme of Harumi Triton Square is "fusion of work, relaxation and living." The business zone for "work" centers on the Office Towers, the compound zone for "relaxation" composed of many shops, showrooms, and schools, and the residential zone for "living" composed of collective housing, thereby forming a well-balanced community. Artificial ground was constructed almost over the entire area of the block to provide zonal demarcation for pedestrians freely walking on the artificial ground and car and service vehicle parking, loading and unloading underground.

6 Green-filled Town Growing with the Passage of Time Harumi Triton Square is richly decorated with greenery on the artificial ground and in the parks, with flowers changing by the season to provide a feast for the eyes of the residents. Six years has passed since the completion of the building. All those plants and flowers are now an integral part of the town. Just completed (2001) Just completed (2001) - 4 -

7 Heat storage tank Heat storage tank Environmentally Friendly System Established The Center Plant, located on the third and fourth basement of Harumi Triton Square, contains substations, water supply and drainage systems, and a district heating and cooling system (DHC) as the core of major service systems to support the block. Under the entrance lobby lies the Integrated Disaster Prevention Center that oversees disaster and crime prevention of the Block and manages the Center Plant. The Center Plant, Integrated Disaster Prevention Center, and other buildings are connected with sturdy utility tunnels to ensure safety.

8 Highly Energy-saving Town Harumi Triton Square introduced various energy-saving systems to comply with the basic three principles "Waste no heat," "Use power efficiently," and "Produce heat efficiently." Water resources are also used effectively in Harumi Triton Square. For example, kitchen wastewater is purified and rainwater on the roof is gathered and filtered for use as toilet flushing water. Waste heat Waste no heat (screening of sunlight and heat insulation). Use power efficiently (lighting, airconditioning, and pumping). Produce power efficiently (DHC).

9 Primary energy conversion COP Remarkable Reduction in Energy and Water Consumption and Waste Production Equipped with a highly efficient DHC and various energy-saving efforts, Harumi Triton Square enjoys savings of about 22% of the primary energy consumption compared with a standard office building. With its primary energy COP being 1.19, Harumi's DHC boasts the second highest efficiency among all DHC systems in Japan. About 45% tap water savings is achieved compared to the situation had there not been a rainwater and wastewater recycling system. About 57% reduction of refuse from office buildings is also achieved compared to the situation had there been no recycling.

10 The heat island effect is a major problem today. Heat islands are a phenomenon related to very hot urban areas in the summer because of thermal input of the waste heat of buildings and thermal reflections from concrete surfaces. Harumi Triton Square has a lot of open spaces covered by plants or permeable paving to prevent the ground surface from emitting heat. Use of a high-efficiency district heating and cooling system also greatly reduces waste heat from the buildings. One of the measures of mitigation of the heat island effect is CASBEE-HI. This assessment system evaluates the influence of the heat island effect in the compound of a site and categorizes the site into ranks from S to C. Because of the earlier mentioned measures, Harumi Triton Square receives the S rank (best rank) in CASBEE-HI evaluations.

11 Integrated collection of related information (every month) Feedback of results Environmental Information Management Activities Harumi Corporation, the integrated manager of Harumi Triton Square, regularly holds environmental information management review meetings to carry out practical activities toward environmental load reduction. Attendants of the meetings carry out various activities, including setting of energy-saving targets, reviewing ways to improve energy-saving measures, and making various measurements, and then compile those results into a monthly magazine, the Performance Report. Those efforts for energy saving have been highly reputed, and Harumi Triton Square has won many awards including the Energy Saving Building Award (the Institute for Building Environment and Energy Conservation) and the Society of Heating, Airconditioning and Sanitary Engineers of Japan (SHASE) Award of Technology.
