Evaluation Of Energy In The Residential Sector In Algeria And 2040 Outlook

Abstract

In this study, we evaluate the energy in the residential sector by follow a bottom up method, before we start the calculations, we analyze the factors which have an influence in the energy consumption, then we start the evaluation by estimating the energy needed in the houses. To estimate the cooling and heating by dividing the Algerian surface to 7 zone using degree days method and ArcGIS (geographic information system) and Google earth. After the evaluation of the energy in the residential sector, we study the energy outlook to 2040 through two scenarios, Business as Usual scenario which counting in the same path without modification, and with alternative scenario, which inject modification by assuming a new paths for the future, after that we analysis the results, we find that we have to treat the houses according to the specification of the zones it located in, when the heating and cooling are respectively represent 6.4% and 19% in zone 1 while it’s 16% and 1% in zone 7. The results shows that the injection of a new kind of lighting and cooling can provide us with a good economic gain which is 458 million € in lighting, while the absorption chiller gain is 24 million € in 2015 and 203 million € in 2040 with the cop of 1.5 and with cop of 1 the gain was 4 million € in 2015 and 36 million € in 2040.
