Abstract
The feasibility of Plus Energy Building for a sample relevant case is investigated. After a literature review aimed to
identify key aspects of this type of buildings, a preliminary evaluation of the thermal performance of a building
constructed using conventional material is presented together with a parametric analysis of the impact of typical
influential parameters. Solar domestic hot water (SDHW) and photovoltaic systems (PV) are considered in the
study. Numerical simulations indicate that for the examined sample case (Beirut in Lebanon) the total annual
energy need of conventional building is 87.1
kWh/y.m2
. About 49% of energy savings can be achieved by improving the building envelope and installing energy efficient technologies. Moreover, about 90% of energy savings in
domestic hot water production can be achieved by installing a SDHW system composed of two solar collectors
connected in series. Finally, the addition of a grid connected PV array system can significantly mitigate the energy
needs of the building leading to an annual excess of energy.
