Foster Carbon-Neutrality in the Built Environment: A Blockchain-Based Approach for the Energy Interaction Among Buildings

Abstract

Decarbonizing urban environments and reducing their energy consumption is one of modern society biggest commitments. In this regard, both the scientific community and international governments have been giving special consideration on improving the energy-environmental performance of mostly single buildings; recently the focus has been shifting towards a broader Positive Energy District (PED)/ Energy Community (EC) vision, from small clustered group of buildings to neighborhoods up until urban settlements. In this respect, integrating the use of renewable energy resources (RES) and actively involving building users can have a significant environmental impact on local areas. Within this framework, this work discusses the possibility of employing an innovative blockchain-based approach for the energy interaction among buildings. The blockchain technology can, in fact, be useful in managing such scenarios since it would allow to, not only consider buildings occupants behaviors, but also take into account concernings regarding the need for transparency, engagement, environmental and human health benefits, as well as the stakeholders role in the interaction/integration between PEDs/ECs and local/national electricity systems.
