Understanding Positive Energy Buildings and Neighbourhoods - towards a common definition

Discussion Paper

Paper Abstract

Positive Energy Buildings (PEBs) represent a step forward from Net Zero Energy Buildings. In particular, they shall contribute by decarbonizing the built environment, including surrounding buildings, exchanging energy among them or with the grid. Thus, they can reduce the energy grid congestion and provide a flexible energy asset that allows buildings and energy communities to act as an integrated part of the energy system, while ensuring healthy and comfortable indoor environment, embracing occupants’ diversities and needs, supporting users’ energy-related practices and their flexibility and minimizing their own carbon footprint.

In this direction, a consolidated definition is needed in order to enable the design, assessment, and documentation of PEBs in different contexts, climates, cultures, and markets. This paper aims to present a joint understanding of the essence and benefits of Positive Energy Buildings applied to the residential sector, as discussed within the three EU-Horizon 2020 sister projects EXCESS, Cultural-E, and syn.ikia. The joint work also led to the identification of barriers and drivers for an increased acceptance and adoption of PEBs and to the definition of a list of recommendations for policy makers.
