| Keyword | |||
| Abstract | In response to the growing challenges of climate change and the global energy crisis, building energy efficiency has become a critical objective in contemporary sustainable design. Thermal insulation performance directly affects indoor thermal comfort and air conditioning energy consumption; therefore, selecting insulation materials that balance energy-saving benefits with construction feasibility is essential to improving overall building energy performance. This study focuses on insulating mortars, selecting three common green building material products from the market—referred to as Green○, Run○, and Te○—and compares them with conventional cement mortar as a control group, aiming to provide quantifiable data to support practical material selection. The experimental methodology utilized a halogen lamp to simulate solar radiation as a heat source. Surface and back temperatures of mortar specimens were recorded over 60 minutes using an infrared thermometer. Based on the data, thermal conductivity coefficients (k-values) were calculated using Fourier’s Law of Heat Conduction. In addition, the study incorporated material cost and consumption to estimate the cost per square meter and derive the cost-performance ratio (CP value) as a comparative index for material selection. The results indicated that both Run○ and Te○ mortars demonstrated superior thermal performance with estimated thermal conductivity values of 0.12 W/m·K, outperforming Green○ (0.16 W/m·K) and the conventional mortar (0.23 W/m·K). In terms of cost, Te○ mortar exhibited the lowest unit cost and the highest CP value, indicating the most favorable cost-effectiveness. The study confirms that insulating mortars are effective in reducing heat transfer, increasing the thermal resistance of building envelopes, mitigating indoor temperature rise, and lowering energy consumption for air conditioning. These findings provide valuable references for architects, design teams, and developers in selecting green building materials and implementing energy-efficient strategies. Additionally, the results contribute to the broader promotion and development of Taiwan's EEWH Green Building Assessment System. |
