Algeria’s buildings sector accounts for about 46% of the country’s total final energy consumption. Between 2010 and 2019, the energy consumption from buildings grew by around 50%. To be 1.5°C compatible, the emissions in the sector would need to decline from 27 MtCO₂e/yr in 2019 to 15 MtCO₂e/yr by 2030 and reach 0–4 MtCO₂e/yr by 2050. The sector could be fully decarbonised by 2044. The decarbonisation would be driven by an increased electrification of total energy demand, from 19% in 2019 to 43–51% by 2030 and 90–91% by 2050.
The government’s Renewable Energy and Energy Efficiency Development Plan (REEEDP), released in 2016, has set a number of measures to reduce emissions in the sector including the improvement of heat insulation of buildings, the development of solar water heating, the substitution of all mercury lamps with sodium lamps, and the promotion of the use of energy-efficient light bulbs. The government aims to reduce energy consumption in the building sector cumulatively by 30 Mtoe between 2015–2030. The planned reduction per year corresponds to about 14% of the current annual consumption.
