Forty-two percent (42%) of Algerian primary energy was consumed by the building sector and it is stillin expansion, due to mainly on an exceptional growth of population and urbanism. In order to reach theincrease demand of housing and to keep the rural areas inhabitants in their lands, the Algerian state haslaunched a huge plan of rural housing construction without taking into account the energy performancelevel which is too bad. The main objective of this work is to analyze the energy performance of ruralhousing built in the district of Chlef for the three construction programs, besides study their impact onthe overall energy balance in the district of Chlef. There are two ways to improve the energy performanceof a typical rural house. First, a passive one through the integration of a set of efficiency measures to reducethe need for heating and air conditioning. The efficiency measures include the adequate orientation ofthe house, insulation of the envelope house, efficient glazing and increased windows size with the use ofshading device in summer.Second, an active one using solar PV to supply the house with electricity. The results show that at theend of the last constructions program, more than 219 GW h of electricity and 26,508t of butane gas couldbe saved annually at the energy balance level of the district. The annual cost savings associated to theseenergy savings was estimated at 1281,933$ for butane gas and at 5110,431$ for electricity. © 2014 Elsevier B.V. All rights reserved.
