Emits low VOCs
Volatile organic compounds (VOCs) are emissions from carbon-containing compounds that pollute the air. VOCs are released from many common building products including solvents, paints and lacquers, adhesives, fabrics, carpets, printed paper, board products and composite timber. Rating schemes often categorize VOC content as low, very low, ultra low and zero.
Reduces water consumption
Products that reduce water consumption can make a valuable contribution to managing natural resources. There are several types of products that reduce water consumption – products that actively save water (water tanks, for example); products that enable the reuse of water (grey water recycling systems); and products that consume minimal water in operation (water-efficient tapware and appliances, self-cleaning glass).
Reduces energy consumption
Making use of materials and products that reduce energy consumption can have a major influence on the environmental impact of a building project. Teaming passive design strategies (orientation, building shape, natural lighting and ventilation) with low-energy lighting, thermally efficient insulation and low-e glass can reduce a project’s reliance on heating and cooling systems, resulting in lower energy consumption. Likewise, use of energy-efficient appliances, alternative energy systems (solar, hydro) and building management systems can also reduce the project’s carbon footprint.
Reduces heating or cooling load
Heating and cooling load is the amount of energy consumed to maintain a desired temperature within a building. Project design – and the materials and products employed – plays a significant role in optimizing the performance of heating and cooling systems, to reduce the energy expended on internal climate control. Elements that affect heating and cooling load include heat transferred through glass windows and doors, infiltration of outside air, and the impact of people, lighting and electronic equipment.
Designed for disassembly
Design for disassembly is a manufacturing strategy that anticipates the future reuse of individual components or materials, enabling a product to be broken into its constituent parts for reuse or recycling. Design for disassembly can make recycling easier, resulting in less use of new resources, less energy consumption and less landfill. In economic terms, design for disassembly gives further value to products beyond their original life. Disassembling a structure rather than demolishing it can also reduce impact on the environment by reducing dust released during demolition, reducing land degradation and reducing transport costs of disposing of materials to landfill.
Recyclable
Recyclable products and materials can be reprocessed and transformed into new goods at the end of their useful life. Materials composed of a single substance (for example, aluminium or concrete) are generally easier to dismantle and recycle than those composed of multiple substances. Employing recyclable materials offers several benefits – reduced use of new resources, reduced landfill, reduced costs for manufacturers.
