エネルギーの面的利用がもたらす間接的便益（NEB）に関する研究（その2）広域的なエネルギーの面的利用における低炭素化対策の限界削減費用の評価

摘要

1．はじめに1．1　民生部門の低炭素化における地域スケールの対策の必要性低炭素社会に向け，民生部門では更なる低炭素化が求められている。この課題に対応するためには，建物，街区，コミュニティ，地姐　都市など，建物単体を超えた様々なスケールでの面的な低炭素化対策の推進が必須の状況にあり，「京都議定書目標達成計画」でも「エネルギーの面的利用」は対策の冒頭にあげられている。%Toward low-carbon society, much higher use of renewable energy and unused energy should be promoted. For this purpose, area-wide energy utilization is expected to play an important role in commercial and residential sectors. Along with the compact city policy, area-wide energy utilization in rather wide scale such as in a community and in a city should be strategically planned and implemented. Among various carbon reduction measures, those of higher reduction potential and higher cost-benefit ratio should be prioritized. This paper describes an appropriate way of determining the priority by use of marginal abatement cost (MAC), taking the following viewpoints into consideration.;1) Setting payback-periods based on functional lifetime of each reduction measure 2) Qualifying non-energy benefits (NEB) to be deducted from the MAC of each reduction measure A case study for a community-scale energy utilization by use of incineration waste heat is undertaken to validate the above concept.
