Research-Based Definition of a PEB

Abstract

Currently, no common definition of PEBs exists, which complicates technical solutions’ and business models' development across different climatic zones. This chapter defines a PEB based on thorough research conducted in the EU-funded EXCESS project. The chapter begins with a discussion on PEB backgrounds, such as PEB concepts' origin and comparison of concepts similar to PEB. After that a technical framework is introduced by presenting different technical criteria that need to be considered. Based on the EXCESS project's research, a positive energy building (PEB) is defined as ‘an energy-efficient building that produces more energy than it uses via renewable sources, with high self-consumption rate and high energy flexibility, over a time span of one year’. After the technical framework introduction, a social framework of PEBs is discussed. Finally, a technically and socially feasible PEB definition is provided. This discussion includes PEB as part of an energy community and PEBs in relation to smart readiness indicator.
