JOURNAL FREE ACCESSInformation Age urges leading metropolises to install information utilities to a high level. The Port Authority of New York & New Jersey has proposed that the cities which own Teleport as an information utility league together. Tokyo has drawn a plan for the Teleport development on a island 6km off The Central Business District. This urban development is generally conceived as one of Cities of Tomorrow.
While Tokyo Teleport will be realized in 6 years, a lot of urban images drawn in 1960's have never been practiced. Though these Images or Projects are based on the optimism relying upon technological progress, the progress could not reach the expected level, and these images have lacked considerations for psychological aspects. In 1970's no large scale images was presented, possibly, because of the economic recession. In 1980's urban developments have revitalized at all over the world, and high-tech images drawn in 1960's have partly realized as some architecture, as the new office building for Lloyd's of London. Though several proposals for the Tokyo-bay development and other architectural images have been presented as in 1960's, only those plans that attach great importance to sensibility, nature, land, rapid transit network, as well as costs may be able to survive.View full abstractDownload PDF (10228K) -

JOURNAL FREE ACCESSThe City of Osaka proposes the Technoport Osaka Project to meet challenges of the 21st century, as part of Centennial Project for the municipality of Osaka.
The project is an ambitious plan for an ultra-advanced urban complex to be constructed in Osaka Bay on newly created islands of a total of some 775 hectares comprising Hokko (north port) and Nanko (south port).
The fundamental functions of Technoport Osaka consist of information communication, advanced technological development, world trade and culture, sports and recreation. Based on this concept, the vast space will be zoned. Technoport Osaka will establish Osaka Teleport therein, which is designed to operate as the nucleus of information communications, equipped with satellite communications base followed by optical fiber networks inside and outside the existing city area. An integral distribution system concerning technological information, trade information, economic information will also be established.
The project is now underway to build infrastructures such as transportation, communication. The earth station facility of Teleport is scheduled to serve in 1989, Hokko bridge connecting Hokko and the exisiting coastal area will be completed in 1989. INTEX OSAKA, a convention facility was established in 1985 and a number of mechatronics research institutes, factories and system houses have begun to be constructed.View full abstractDownload PDF (803K) -

JOURNAL FREE ACCESS1. Outline
In order to solve such problems as shortage of land in big cities and to prevent the sprawling of the cities, and to utilize the space up in the air, 1, 000m higt-rise building is proposed and create a new city.
-A building or buildings of 150 to 200m square in total plan is proposed to be built on the land of 1km to 2km square and the height of 1, 000m.
-Total floor area: Approx. 1, 000ha (10, 000, 000m2)
200m×200m=4ha,
If the story height is 4m, then the number of the story is 1, 000m/4m=250 stories 4ha×250 stories=1, 000ha,
(If the volume ratio is 100%, then the required land area is 1km square.)
-This total area is equivalent to that of the Musashino city, Tokyo, the statistics of which is the following according to the census of 1985
Population: 138, 783 No.of families: 59, 041 Area: 1, 103ha
-Assuming that the entire floor area is used as intelligent office, the capacity of the building will be as follows.
If the office gross area of 30m2 is assumed to be necessary per worker, then the capacity is: 1, 000m2/30m2=approx. 300, 000 workers

JOURNAL FREE ACCESSIn order to build a holonic energy supply system within the urban area in the next 21 century, the electricity generated by the nuclear power plants or by the coal fired power plants is used for the base load demand, and the electricity generated by small-sized cogeneration plants distributed within urban area is used for the peak load demand. Such cogeneration plants should burn imported oil and LNG, and should supply heat simultaneously. The big concentrated system as nuclear plants and the small distributed systems as cogeneration make up weakness each other. In the next century, people want the amenities of life so that they need the varieties for the energy supply. For example, people may demand variable voltage or variable frequency for the electricity, even direct current.
In such era, the cogeneration systems seem to have strong capability. This paper discusses the trend of technological developments of cogeneration and the points to be politically brushed up.View full abstractDownload PDF (1766K) -

JOURNAL FREE ACCESSIn discussing realization of the future city plan, there are lots of factors to be studied related to natural energy resources. The outline of Super Heat Pump Energy Accumulation System (SHP), which now promotes R & D being supervised by AIST and NEDO, is introduced, and hopefully R & D will be an aid in further progress of the future city plan.
SHP is the integrated system, combined use of high efficient compression heat pump (2 times COP capable than conventional one) or high temperature compression heat pump (150°C-300°C output) and the chemical storage utilizing chemical reaction. The concept is to store the high efficient/graded thermal energy by electric power during night, and use it when required. The project launched in 1984 for 8 years, thereby contributing to energy conservation and levelling power demand by applying to space conditioning for large buildings, district heating/cooling, domestic hot water & industrial process heat. Bench plant in size of 100 kW is scheduled by the end of 1988.View full abstractDownload PDF (961K) -

JOURNAL FREE ACCESSIn recent years, the siting problem of a large capacity, concentrated power station, especially of nuclear power plant has become serious. Under these circumstances, a new concept has been proposed such that a energy resource must be dispersed in a manner to meet its demand of each area. The concept will change the fundamental constitution of energy system and give a great influence to city planning itself of the area as well.
A photovoltaic power generation system can be recommended as a leading member for the dispersed power system because of its nature, e.g., simple system, clean energy, easy handling, maintenance free, etc. It cannot be forgotten for the urban construction of the future.
The author explains about a present status and an activity of photovoltaic power generation in accordance with such viewpoint. Further contents are the statistics of solar cell production and its cost, and the technology flow regarding cell production processes and applications, future aspect on conversion efficiency improvement of various kinds of solar cells, a principle system configuration diagram, system classification, etc. Trends in the commercialization toward the introduction to a future city and problems on electric power network at the introduction are also mentioned.View full abstractDownload PDF (1183K) -

JOURNAL FREE ACCESSThis report tells what the recent movement of urban redevelopment is, what electric power companies are doing for that, and what the district heating and cooling (D. H. C.) system with heat pumps is, especially in the water-front area in Tokyo.
Now the movement of urban redevelopment is spreading all over Japan with its first step in Tokyo. D. H. C. system is also in the limelight, because it has high energy conservation and good environmental preservation. Namely, D.H.C. system with heat pumps has high coefficients of performance (3-5) and discharges no pollutants (NOx and SOx), to keep urban environment clean and safe.
In this report D. H. C. system utilizing urban wasted heat is described, which provides heat in the water-front area in Tokyo. Example systems in Hikarigaoka Park Town and Shibaura 4-chome Distric where D.H.C. systems are in actual operation are also demonstrated.View full abstractDownload PDF (1144K) -

JOURNAL FREE ACCESSMore than ten major development projects have been announced on the waterfront of the Port of Tokyo. Totally, these projects will include 565 hectares of land to be developed into new CBDs (Central Business Districts) and high-rise apartments. The total floor area is expected to reach 1, 480 hectares. As for energy, 500MW of electricity and 730 Gcal/h of heat is expected to be consumed in this area totally at the peak.
In order to lead these projects successfully, the installment of efficient infrastructure will be of utmost importance. Especially, design of a reliable energy distribution system will be essential. Co-generation should be a good alternative, because with Tokyo's reliable city-gas pipelines, it will assure the stable supply of electricity even under the breakdown of the conven-tional power grid.
A choice between a centralized and decentralized system will also be important. Latter should work better in this area because of its scattered energy demand.
It is without doubt that Tokyo's role as a world center will grow even more in the future. As long as the function of the city can be maintained only by the stable supply of energy, con-struction of a more reliable energy distribution system will be essential to the future growth of this area. For this purpose, cooperation between public and private sectors such as power and gas companies is expected as well as the development of innovative energy conversion systems such as fuel and photovoltaic cells.View full abstractDownload PDF (3108K)
