Energy savings in the Jordanian residential sector

The aim of the present study is to evaluate the reduction in energy use in terms of consumption and cost in the jordanian residential sector resulting from applying energy efficiency measures. a baseline model for houses in jordan has been developed to represent the average dwelling unit in terms of construction and energy consumption using the outcome of governmental surveys. three energy efficiency measures were introduced individually and simultaneously in five scenarios. the energy savings from each scenario were simulated using hourly analysis program (hap) software and then quantified by comparison with the energy consumption in the baseline. it was found that using enhanced building envelop material can save 24% in energy consumption and 22% in energy cost. replacing conventional lighting fixtures with efficient fixtures can save 7% of consumption and 10% of cost while the savings from replacing electric water heaters with solar heaters can be 8% in consumption and 13% in cost. if all measures are applied simultaneously,the realized savings were estimated to be 39% in consumption and 41% in cost. finally,applying the practically viable measures (efficient lighting and solar heaters) can achieve 15% savings in consumption and 22% in cost. © 2017 jordan journal of mechanical and industrial engineering.
