Abstract
This study aims to enhance the energy efficiency in cold climates, specifically Shahrekord, by exploring the integration of solar water heater systems and photovoltaic panels into building facades. Employing TSOL 2021 R(3) and HOMER V.2.81 software, this research adopts a novel approach to address the energy efficiency challenge. The placement of solar equipment on the southern facade yields a 44.6% increase in electricity generation and a 59.3% rise in heat production compared to the western facade. This significant difference is attributed to the larger collectors and optimal orientation in Scenario 1, resulting in a remarkable 45% greater reduction in pollutant emissions. The primary losses in the first scenario are associated with optical inefficiencies, whereas thermal inefficiencies in the solar collector drive losses in the second scenario. Despite having more solar panels, electricity costs are 19% lower in the first scenario, contributing to a higher proportion of solar electricity. This research provides valuable insights into optimizing energy efficiency in cold climates through strategic solar equipment placement, emphasizing the economic and environmental advantages of such integrations.
