Investigating the Impact of Integration the Saudi Code of Energy Conservation with the Solar PV Systems in Residential Buildings

The demand for air conditioning is increasing day by in the world’s hot and humid climate areas. Energy conservation buildings can play a vital role meeting this high cooling demand. This paper attempts to consider impacts of energy efficiency renewable measures on Saudi Arabia’s residential buildings. analysis economic feasibility thermal insulations are performed investigating effect buildings’ grid-connected photovoltaic systems. was combined effort building owners government, were examined if system insulation used. study conducted three zones Arabia. results showed that base case’s annual electrical consumption Riyadh city 67,095 kWh, Hail 57,373 Abha 26,799 kWh. For basic case-building Riyadh, 69% total used heating. Applying Building Code requirement will provide only 18% RETScreen 6.1 software design system; done using technical indicators. yield factor Hail, 1649 kWh/kWp/year, 1711 1765 respectively. capacity factors 18.8%, 19.5%, 20.1%, Unified Levelized costs 0.031, 0.030, 0.029 $/kWh Abha, Finally, Net Present Value greenhouse gas emissions reduction have been estimated.
