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.

摘要：The heating load simulation models of the residential buildings in Lhasa are established for enhancing the space organization’s adaptability to climate and radiation and improving its energy saving *** space organization items a e analyzed for both the existing buildings without insulation and new buildings with good *** items include orientation design,south a d north balcony design,the north and south partition wall’s position design,storey height design and window-wall ratio *** results show that orientation is the key design element for energy saving design,and adverse orientation can obviouslyincrease heating energy consumption;south and north balconies can reduce winter heating energy consumption;partition walls move to the north,which means that the south room’s big depth design leads to less heating energy consumption,but the effect is not inconspicuous;smaier storey height results in less heating *** the existing buildings,the window-wall ratio of south side has a balance point for energy saving design in the calculation *** the new buildings with good insulation,enlarging the south window-wal ratio can continuously reduce heating energy consumption,but the energy saving rate between models gets *** heating energy consumption comparison study between the common model and optimal space design model demonstrates that the energy saving design can significantly reduce heating energy consumption
