(wood, hemp, straw, bamboo) that have sequestered carbon during their growth before being transformed into a building material. o Using recycled materials or reclaimed materials can reduce the emissions associated with manufacturing new materials.(RMI) 6 Fig: Embodied carbon reduction strategy (Source: WEF) Lecture 2: GHG as a global phenomena  05 Strategies to reduce GHG emissions Lifecycle Assessment Conducting lifecycle assessments to evaluate the environmental impact of a building from construction to demolition, considering factors such as materials, energy use, and end-of-life disposal. Buildings are major sources of greenhouse gas (GHG) emissions and Fig: Lifecycle Assessment of Building (Source: RMI) contributors to the climate crisis. To meet climate- o Carbon is calculated as global warming potential (GWP) and expressed in carbon dioxide change mitigation needs, one must go beyond equivalent units (CO2e). operational energy consumption and related o To quantify a product’s embodied carbon, an analysis called life cycle assessment (LCA) is GHG emissions of buildings used to assess the environmental impacts associated with each stage of the product and address their full life lifecycle. cycle o The disclosure of LCA results through Environmental Product Declarations (EPDs) provides valuable information to consumers about the environmental impact of building products.(RMI) 7 Lecture 2: GHG as a global phenomena 05 Strategies to reduce GHG emissions Energy Efficient technologies Installation of energy- efficient appliances, lighting, and water fixtures to minimize energy and water consumption within buildings.
