2 Promotion of Green housing and building in Japan -Standards, voluntary measures and other incentives- Ministry of Land, Infrastructure, Transport and Tourism Dr. Takao Sawachi Director, Dept. of Environmental Engineering Building Research Institute of Japan March 03 On behalf of Ministry of Land, Infrastructure, Transport and Tourism Trend of Energy Consumption and CO Emissions in Housing and Buildings Housing and buildings account for more than 30 percent of total energy consumption in Japan. With significant increase in the last two decades compared to industrial and transportation sectors. Against the backdrop, measures to improve energy efficiency have been called for. CO emissions of the housing and buildings sector have also increased significantly than other sectors. Trend of Final Energy Consumption Trend of CO Emissions (PJ) 8000 Total of 3 sectors % increase million tons Industrial sector (factory etc.) % Transportation.9% % increase 4 million tons % 50.3% Housing and buildings Industry 33.% 43.9% 運輸部門民生部門 % 産業部門 increase % decrease (Unit: million t CO) 7 million tons Business and other sectors (commerce/service/business office etc.) 64 million tons 7 million tons 68 million tons 60 million tons million tons Transportation sector (automobile, etc.) Household sector Energy conversion sector (power generator etc.) Industrial process Waste (incineration, etc.) 3 million tons 7 million tons 7 million tons 8million tons 4million tons 7million tons 3.9% 34.8% (FY) (FY)

3 Main Causes of the Increase in Energy Consumption in Housing and Buildings Housing Changes in lifestyle including increase in the number of households and use of electric device are believed to have large impact on the growth of energy consumption in the housing sector. Trend of Energy Consumption in Housing Sector and Increase in Households Energy consumption Number of household Energy consumption/number of household Buildings The main reason for the growth in energy consumption in buildings is believed to be changes in usage including the increase in floor space and period of use (business hours).

Climate and lifestyle differ greatly by country or region and, as a result, the structure of energy consumption differs. Thus, energy saving measures that suit their own country or region are needed.

As for housing, the standard compliance rate, which used to be less than 0%, increased to approx. 50% as a result of the introduction of housing eco point program. (Unit: %) Trend of Energy Saving Standard Compliance Rate of Newly Constructed Buildings* (999 standard) (Unit: %) Trend of Energy Saving Standard Compliance Rate of Newly Constructed Housing* (999 standard) 7 9 It rose to approx. 50 percent in Fy0 as a result of the introduction of housing eco point program Energy saving measures notification became required in April 003. Types of buildings required to report their energy saving measures were widened in April 00. *Ratio of floor space of buildings that comply with energy saving standard (999 standard) out of all buildings with a floor space of,000 m or more whose construction was certified in the applicable year Energy saving measures notification became required in April 006. Types of buildings required to report their energy saving measures were widened in April 00. * Estimate until FY00 is based on a survey on distribution of the number of households complying with housing insulation standard, and estimate for FY0 (provisional figure) is based on the number of households for which eco points are issued (detached house) as well as notification survey of energy saving act (condominium, etc.) 7 4

6 Overview of Regulations on Housing and Buildings under Energy Saving Act Efforts are requested to be made to meet the standard for insulation of exterior wall and windows and air conditioners (energy saving standard) when housing and buildings of a certain size are newly constructed and notification to prefectural governments are required (instruction, announcement, order, penalty are issued or imposed when they are considered significantly insufficient) Law revision in 008 extended the target of the notification requirement (housing and buildings with floor space of,000 m or more 300 m or more). Energy saving standard is planned to be reviewed to use easy to understand indicators of energy consumption instead of standard using insulation specifications. Regulations on new construction under Energy Saving Act (*) Target Structure Requirements Security Measures when Energy Saving Efforts are Significantly Insufficient Large buildings (000m or more) Notification required Instruction, announcement, order, penalty (fines of million or less) Mid-sized buildings (300m to 000m ) Notification required Recommendation (no penalty) Small buildings (less than 300m ) Efforts required No Builders that build 50 or more ready-built detached houses per year Efforts required Recommendation, announcement, order, penalty (fines of million or less) * In addition to regulations for new construction, notification at major renovation and periodical report of every three years after the notification are required. Energy Saving Standard (Housing) Assessed based on insulation specifications of exterior wall and window Exterior wall insulation 00mm Continuous damp proof air sealing course Ceiling insulation 80mm Air conditioning for heating and cooling Floor insulation 00mm Sunshade for south and west windows Permanent ventilation system Eaves of south window Double glass window (if possible insulation glass) In Tokyo Established in 980 and enhanced in 99 and 999 (GJ/year, household) 8 Before % Comparison of Annual Energy Consumption for Heating and Cooling* standard 99 standard 999 standard (* Estimated based on certain assumptions by MLIT) 8 Overview of Reviewing Energy Saving Standard The current assessment system of energy saving standard for housing and buildings in which outside insulation property and performance of individual facility are assessed separately is revised to use integrated assessment standard of the entire building, using primary energy consumption as the indicator. Set up a calculation method that allows proper assessment of energy saving property in accordance with the use and floor space. Outside standard (999 level) of housing and buildings is required to be met in principle. Because the target year of the advanced housing standard is FY03, current standard is maintained in principle.

12 Low Carbon City Promotion Act (Outline) Background The Great East Japan Earthquake triggered changes in energy supply/demand and raised awareness about energy and global warming issues among the people. It is important to accumulate successful examples of low-carbon cities development and transportation system as well as to rationalize energy use in urban areas by promoting private sector investment, thereby vitalizing housing market and local economy.

Countermeasures for the heat island Taking measures to contribute to control heat island like planting trees on the site, roof top and wall surface. Requirement should be to secure insulation performance which is equal to or higher than Energy Efficiency Standard of Energy Conservation Law.
