Virtual Performance Evaluation of Net-Zero Energy Building (NZEB) Using BIM Analysis

Residential buildings are built to accommodate daily uses which need energy for heating, lighting, and cooling. Net-zero energy building (NZEB) is a building that makes a balance between the energy supply and production by decreasing energy demand and generating power using renewable resources. Building-integrated PV/T systems (BIPV/T) increase the total energy gain and take advantage of cooling fluid as a heat provider for buildings. Building information modeling is used as a virtual simulation to an existing apartment building of the Bismayah project to measure the effect of adding (BIPV/T) systems to the conventional power sources. Results showed the effectiveness of renewable power collectors in (heating, cooling, lighting, etc.) with the recommendations to increase the self-dependency of power building depending on renewable power sources.
