Abstract

The article presents an innovative design schema for air circulation within collective housing, which effectively reduces energy consumption and improves the indoor environment. It also solves the problem of the high operating and maintenance costs caused by the simultaneous installation of air conditioners and radiators. Employing dynamic energy consumption calculation software THERB for HAM, the energy-saving benefits of this design are simulated. The strategy involves capturing heat within the sunspace and transferring it to the conditioning chamber, from where the air is tempered and circulated throughout the habitable spaces to minimize heating. The findings suggest that by strategically using sunspace heat, heating energy can be significantly reduced by 43%. It helps to promote the development of sustainable building design. A comparative analysis of window materials in the sunspace, including single glazing, double glazing, and low-e double glazing, indicates that windows with enhanced insulation properties can substantially decrease the heating energy. Considering both energy efficiency and economic feasibility, low-e double glazing is identified as a particularly advantageous choice.
