MLIT Government Green Buildings Program: The Government Buildings Department of the Ministry of Land, Infrastructure and Transport (MLIT) is responsible for the greening of government buildings. As with most other federal governments promoting the increasing use of green building, the Japanese federal government is greening its buildings to show what can be done to reduce the environmental load of a building from its planning stage through its construction, use, and eventual disposal. This governmental effort includes the building of brand new green buildings, as well as the renovation of older buildings to incorporate new technologies and to make them more sustainable. In July 2004, the Government Buildings Department established the “Environmental Load Reduction Program on Government Facilities (Government Green Buildings Program).” The program was established based on a thorough evaluation of the measures that need to be taken to ensure that environmentallyfriendly practices are promoted comprehensively in government facilities and to demonstrate that the government can play a leading role in the field of public buildings. To promote the program to the public, the Government Buildings Department will actively publish information relating to the progress of this program and environmental load reduction, through means such as websites. The department will also create and publish an annual environmental report. Overseas Performance Evaluation and Approval initiative: While Japan has its own green building rating system (CASBEE), the MLIT’s Housing Bureau runs an applications program for the recognition of Overseas Performance Evaluation and Approval Organizations in Japan. For a system like LEED or BREEAM to become recognized in Japan, a representative from these rating systems must apply to the Housing Bureau and have them review the standards and performance measures of the system. If the system is deemed valid by the Housing Bureau, then it becomes officially recognized by the Government of Japan as an applicable green building rating system. Japanese Building Research Institute’s Department of Environmental Engineering (DEE): The Japanese Building Research Institute’s Department of Environmental Engineering (DEE) is developing various methods and technologies to efficiently build resource- and energy-saving, healthy, and comfortable buildings. It also studies the life styles of people, which is directly related to energy consumption, and develops methods for evaluating and examining the environmental performances of buildings. Current projects by the DEE include experimental research for residential cross ventilation, sun shading design, soundinsulation, and efficient heating, ventilation and air conditioning (HVAC) systems. The Department of Building Materials and Components (DBMC) analyzes the basic physical properties of building materials and components, investigates methods for maintaining and repairing buildings, and examines new materials, such as composite materials. To meet present public demand, the Department conducts basic studies, interdisciplinary studies, and pioneering studies such as development of new materials of high quality and high performance to meet public demand in the future. The DBMC is presently 89
conducting research and experiments concerning waste minimization during building and dismantling stages, advanced building material recycling techniques, long-term durability studies, and environmental assessments of various building materials. Environmental Activity Evaluation Program: The Japanese Ministry of the Environment has released its Environmental Activity Evaluation Program guidelines and made them available online to help people conduct environmental self-assessments of their homes, businesses and activities. Although there is no quantitative aspect to the guidelines, they are fairly comprehensive and if the assessment is done properly, it can lead to the identification of areas needing improvements in order to save resources, reduce pollution, increase energy efficiency, etc. The assessment takes the form of a plan-do-check-act procedure and promotes continual improvement. The guidelines are available online at http://www.env.go.jp/policy/jhiroba/PRG/pdfs/e_eco_action.pdf. The Ministry of the Environment’s website has more specific guidelines and assessment standards available for a variety of green building areas including noise pollution, recycling and waste management, air quality, transportation, site characteristics such as heat islands, etc. They can be found at http://www.env.go.jp/en/ through the navigation bar on the bottom left of the page. Yanepita Photovoltaic Systems: Japan also has numerous initiatives being carried out by private companies. In 2003, as one of its series of “Sunbest” photovoltaic systems, Matsushita Electric Works Ltd. of Japan launched sales of the “Yanepita,” a PV power generation system that is specially designed for installation on the slate tile roofs of existing houses. When installing a PV system on slate roofs using conventional methods, it was difficult to overcome problems of the systems developing rain leaks and being blown off by the wind. To overcome these problems, Yanepita involves installing special bases on the existing slate roofing and then the ultra-thin solar modules, only ten millimeters thick, on top of the bases. Since its height above the tiles is only 40 millimeters, the system has no negative effect on the appearance of houses. In addition, the system excels in durability, waterproof and windproof qualities. The company says that the system can be easily installed on alreadybuilt houses. The outer dimensions are 1,191 x 792 millimeters, and as each panel is independent, installation of the system can be flexible depending on the shape of the roof. Residential geothermal heat pumps: Sunpot Co., a heating appliance maker in Japan, and Hokkaido University have codeveloped a geothermal heat pump unit and in 2004 became the country’s first manufacturer to start mass-production of residential geothermal heating units. The system involves digging a hole in the ground about 10 centimeters in diameter, 75 to 100 meters deep, and inserting a polyethylene pipe filled with an antifreeze solution. The system absorbs ground heat as a thermal source for the heated water system. Ground heat is a stable natural energy source that takes advantage of ground temperatures consistently two degrees Celsius warmer than the local average annual air temperature, unaffected by heavy snow or variations in surface air temperatures. The new heat pump can produce the equivalent of four times more heat energy than the electricity the system consumes. The system is not only energy efficient but also helps reduce fossil fuel consumption, 90
