A Comparative Study Between Jordanian Overall Heat Transfer Coefficient (U-Value) and International Building Codes

摘要

Depletion of fossil fuel and the environmental effect associated with the use of it have made the topic of "thermal insulation regulations" a major concern in Jordan and worldwide. This paper reviews the overall heat transfer coefficient U-value in Jordanian code for the building envelope, which represents how much the building envelope transfer heat to the outside environment. U-value was reviewed with respect to the following factors, heating degree-days, the heating load required to achieve thermal comfort. Based on the review a new U-value of 0.65 W/m^{2.K was proposed and it was found that this value reduces the energy demand by half.}
