Abstract : During the recent few decades, researchers as well as politicians are more concerned with the concept of low energy buildings. This is not a new concept since old houses and historical places were built taking into consideration the local climatic conditions. Today such approach is gainingmore attention worldwide and new codes and regulations are introduced in this regard.
In this work, a comprehensive techno-economic feasibility study of a new small independent house (with a total area of about 100 m2) in Amman is conducted using a commercial software package for calculating heating and cooling loads (HAP). A special tailored program to examine the techno-economic feasibility was developed for this purpose. This house is totally dependent on solar energy for supplying electric power and thermal energy. Consequently, gaseous emissions, including GHG, were reduced significantly.
It was found that, with using appropriate energy storage system, there is no need to withdraw electrical power from the grid nor buy fuels for heating purposes. The expected monthly savings in energy cost may reach JD 260 with a payback period of about 8 years.
