地方自治体における建築物環境配慮計画書制度の実効性の分析

タイトル（英文）

Analysis on Effectiveness of "Reporting System of Environment-conscious Building" in the Local Governments

概要 （図表や脚注は「報告書全文」に掲載しております）

低炭素都市の実現のために建築物の省エネ性能の向上が求められているなか、本報告書では、かかる地方自治体政策としての建築物環境配慮計画書制度に焦点を当て、行政法学的視点より制度の実効性について分析する。分析結果は以下のとおりである。第1に、本制度は、環境配慮措置導入の努力義務および届出義務の履行を、「勧告＋違反事実の公表」措置によって実効性を担保しようとする仕組みであり、法的拘束力は決して強いものではない。第2に、本制度の届出率は必ずしも高いとはいえず、基準適合率の向上策の導入状況は必ずしも充実したものにはなっていない。第3に、いくつかの団体では、届出率や基準適合率の向上策として、建築物計画書制度と建築基準法における建築許認可制度とをリンクさせる手法や、建築物環境性能表示制度(ラベリング制度)が導入されており、一定範囲において制度の実効性を向上させることが可能ではあるが、そこには課題もある。

概要 （英文）

To reduce GHG emission, improving energy efficiency of buildings is should be promoted. Also, along with the tendency of decentralization, local governments are expected to play leading roles in architecture and city planning toward low carbon cities. The purpose of this study is to draw lessons for policy on energy efficient building by analyzing the effectiveness of "Reporting system of Environment-conscious building" which has been diffused among many local governments in recent years. With a perspective of administrative jurisprudence, we conducted a legal structural analysis of the ordinances in 15 local governments, and surveys of the operation by interviews to the officers of 6 local governments and a questionnaire survey distributed to 21 local governments, of which 20 were responded. Main results are as follows.
1) A characteristic common to all the systems is that it obliges the owners of new building above a certain size to report the status of their environment-consciousness, and local governments disclose the evaluation results of those reports while the details of the system such as the building of subject are different in each system. The legal binding force of the system is not effective enough because owners' obligations to be fulfilled is not fully clear except for notification and moreover the sanction in default of notification is limited to "administrative advice and breach declaration"
2) As induction measures, increasing the ratio of notification and the preparation of incentives to the owners to address improving energy efficiency of buildings are essential. Nonetheless, as for the ratio of notifications, only one local government answered 100% while 10 local governments answered less than 90% or not figured out. Also, 8 local governments prepare no effective measures to give owners incentives to improve energy efficiency of their buildings.
3) Some local governments have introduced a measure linking the reporting system to the procedure of building certification application under the Building Standards Act, and a labeling scheme. The system could be effective to some extent if it would involve these measures.
