WHY aims to provide a better understanding of electricity demand in the residential buildings sector, in order to improve the design of relevant policy and modelling tools. On the policy front, WHY will propose ways of better reflecting demand-side needs in policy-drafting and assessing energy consumption trends for different categories of economic agents and consumers at EU and national levels. In addition, WHY will improve the quality of Energy System Models most commonly used at European level, including PRIMES, PROMETHEUS and TIAM-ECN modeling tools, by further developing and/or adding features that focus on coupling the energy demand and supply sectors (i.e. through distributed generation, storage, demand response, electrification of services, etc.) as well as behavioral patterns in decision-making by final consumers.
E3M will contribute to the development of the WHY toolkit mostly through improved modelling of demand response, prosumers, electric mobility, sector coupling and interoperability of electricity, gas and heating markets and link it with PRIMES and PROMETHEUS energy system models. E3M will also lead the scenario definition, develop a social impact assessment that focuses on energy efficiency measures and draft policy briefs that draw the link between the WHY project and EC benchmark studies, such as the EC Winter Package and the EC “Clean Planet for all” strategy.
