Material Library for HVAC Load Calculator
Updated 2025-05-17: Removed original materials and constructions, deleted ASHRAE materials starting with 'R' followed by number (e.g., R01, R25), verified constructions use valid materials.
Updated 2025-05-17: Added all materials and constructions from ASHRAE_2005_HOF_Materials.idf with Australian-specific embodied carbon and prices.
Updated 2025-05-17: Added GlazingMaterial and DoorMaterial classes, included library_glazing_materials and library_door_materials with comprehensive data.
Updated 2025-05-16: Removed mass_per_meter, added thermal_mass method, updated CSV handling.
Updated 2025-05-16: Fixed U-value calculation in Material.get_u_value.
Updated 2025-05-16: Updated MaterialCategory to Finishing Materials, Structural Materials, Sub-Structural Materials, Insulation.
Updated 2025-05-16: Fixed Construction.get_thermal_mass to use avg_specific_heat.
