Sustainability in lighting is usually linked to energy use only, but it is time to face the real challenges of quantifying the impact of design decisions made throughout the product life cycle. While we may not have complete information on life cycle impacts, we cannot afford to wait until comprehensive information is available to inform our specification decisions. This presentation will provide a framework for weighing operational energy use, embodied carbon, and material impacts. Leave this session empowered to discuss high level project goals, associated impacts along the supply chain, and steps you can take right now to have a positive environmental influence in the short and long term.
