Decarbonization of the building space heating sector (DeGeb)

Duration: November 2018 until October 2021

Project coordination: Agora Energiewende Berlin

Cooperation partners: University of Kassel (Chairs of Empirical Economic Research, Energy Economics, and Foundations of Law, Private Law and Economics of Law), Fraunhofer Institute for Energy Economics and Energy System Technology (IEE) Kassel

Funding institution: Federal Ministry of Education and Research (BMBF)second phase of the funding priority "Economics of Climate Change" ("Ökonomie des Klimawandels")

Summary: Heating residential and non-residential buildings is one of the substantial sources of CO2 emissions. Buildings and heating systems are long-lasting goods that are prone to path dependencies, which turn decarbonisation into a challenge. The impact of available options like energy efficiency and renewable energies depends on whether they are actually chosen by home owners. Hence, the impact mainly depends on incentive structures and the underlying regulatory framwork. Apart from public law, this mainly refers to private law which governs relationships between actors like landlords and tenants, owners and communities of owners, and providers of heating systems or heat grids. Within the scope of the project, impacts of micro incentives on the energy system transformation in the building sector are examined, the role of corresponding regulatory frameworks is analysed, opportunities for stimulating sustainable investment decisions are assessed, and policy implications are derived. The objective of the project is a comparison of the aggregate impact of different regulatory frameworks in the decarbonisation of the building heat sector.
