摘要：The objective of this study is to identify cost-optimal efficiency packages at several levels of building energy savings.A two-story residential building located in Jordan is selected as a case *** software is used to predict the annual energy usage of a twostory residence in Irbid,***-time experimental data from a single isolated controlled room was used to verify the proposed *** addition to energy analysis,the economic,environmental,and social benefits of the proposed design have been *** sequential search optimization approach is used to estimate the minimum cost of the building while considering various design *** addition,the impact of various energy conservation techniques on residential buildings is assessed,and the payback period for each program is ***,the optimal combination of design to achieve energy efficiency measures has been identified in several climate *** simulations results predict that the annual electricity consumption can be reduced up to 50%if the proper combinations of energy conservation measures are selected at the lowest *** payback period is 9.3 ***,energy efficiency measures can lead to a total of 9470 jobs/year job *** study provide practical framework to link between energy performance criteria and economic goals of *** the energy performance requirements to economic targets provides guidelines for homeowners,contractors,and policymakers for making a suitable decision regarding the retrofitting of existing residential *** study focuses on developing new methodologies that support minimizing costs during a building’s lifecycle while maximizing environmental benefits which can not be identified by a series of parametric analyses using individual energy-efficient measures.
