Energy Sufficiency in the Household Sector of Lithuania and Hungary: The Case of Heated Floor Area

Economic development and rising welfare lead to higher demand for energy services, which can limit or even negate the results of costly efficiency (EE) upgrades. At present, some consumption patterns in Central Eastern European countries are more sustainable compared Union (EU) average but rapidly approaching it. Energy sufficiency (ES) leading an absolute reduction will be essential achieving net zero climate goals, as it contribute reducing use significant investment needs associated with electrification system. Various regulatory solutions deployed pursuit ES targets, little information is available on possible impacts greenhouse gas (GHG) emissions, especially at national level. This paper focuses residential building sector two countries: Lithuania Hungary. It attempts quantify potential reduction, GHG savings resulting change mix from limiting per capita heated floor area using scenario analysis MESSAGE HU-TIMES system models. The findings suggest that final could reduced by 3.6% 0.9% would a production lower emissions new generation capacity. research indicative, no costs were assigned measures calculations based assumed levels indicators. However, they worth identifying segments potential, combination relevant largely achievement emissions.
