ABSTRACT: In order to identify the optimum U-values for the construction elements, we have
simulated the thermal behavior of an apartment which is the most commonly constructed building type
with the highest energy use in Amman, Jordan. It was shown that it is possible to achieve good indoor
thermal comfort by applying a climate-conscious design without the excessive use of energy in
mechanical heating and cooling systems. The optimization process carried out for the climate of
Amman found the requirements on thermal transmittance (U-value) for both roofs and walls to be
between about 0.5 and 0.7 W/m²K. The optimum window to floor ratio (WFR) for a south oriented main
façade was found to be between 12% and 20%. These requirements would allow a total saving in
energy for cooling and heating of up to 70% for a typical apartment in Amman.
