Nearly Zero-Energy Buildings: Optimal Cost of Minimum Energy Requirements

Abstract

Energy Performance of Buildings Directive (EPBD, 2010/31/EU) requires Member States to introduce minimum energy performance requirements for buildings, and set these requirements based on a cost-optimal methodology. This methodology introduces the prerequisite to consider the global lifetime costs of buildings to shape their future energy performance requirements. Methodology predicts that, beside the investment costs, the operational, maintenance, disposal and energy saving costs of buildings should be taken into account.This paper discusses the use methodology related to nearly Zero-Energy Buildings (nZEB) requirements.
