Özet
Buildings account for a major share of global energy use, and reducing heat losses through masonry envelopes is essential for low carbon construction. This paper presents a comparative assessment of several experimentally developed insulation solutions, including a contemporary insulation plaster (CIP), bamboo fibre-reinforced briquettes (BF-B), hazelnut shell-modified plaster (HS-P), tea waste-modified plaster (TW-P), and pineapple leaf fibre-modified plaster (PALF-P). All systems are evaluated using laboratory-scale coheating tests, and their thermal performance is compared based on U-value reduction and increased thermal resistance. The reference briquettes observe high U-values, ranging from approximately 4.62 to 5.50 W/m2K. The CIP reduces the U-value to 2.86 W/m2K, whilst bamboo fibre addition achieves 2.77 W/m2K at 6% content. PALF-P diminishes the U-value to 2.50 W/m2K. Greater improvements are obtained with hazelnut shell and tea waste additions, reaching minimum U-values of 2.04 and 1.47 W/m2K, respectively. The TWW-P shows the highest thermal resistance improvement (73.3%). Overall, the outcomes demonstrate that bio-based and waste-derived plaster systems can provide effective, low-cost, and circular alternatives for energy-efficient building retrofits.
