In this study, the energy efficiency of structural lightweight concretes (SLWCs) used in residential buildings was
evaluated compared to normal weight concrete (NWC). Initially, the compressive strengths, unit weights and
thermal conductivity coefficients of the SLWCs and NWC produced were determined experimentally. The
energy needs calculated were compared regarding each concrete mixture with the 3+1 reference flat. The
monthly and annual heating and cooling loads of the flat were calculated for the different concrete types using
the DesignBuilder energy simulation program. At the end of the study, it was found out that SLWCs provide
energy savings ranging from approximately 26% to 30% compared to NWC. Thus, it has been determined that
SLWCs increase the annually energy savings of buildings between 8126.69 kWh and 9248.44 kWh.
