Washington D.C., USA, September 18 2018: LEED v4.1 emphasises on the improvement of IAQ through the impact category “health and human experience,” said Marisa Long, Vice President, Communications, U.S. Green Building Council (USGBC). She added: “Requirements and options within the Environmental Quality (EQ) section, balance the need for prescriptive measures with more performance-oriented credit requirements. Also, low-emitting materials credit is performance-based and measures the actual emissions from the product, instead of only the VOC content.”

While highlighting how LEED v4.1 has been positive in the market, demonstrating leadership, she said, “Buildings today are responsible for an enormous amount of energy use, resource consumption and greenhouse gas emissions, but LEED 4.1 continues to be a cost-effective solution that transforms the built-environment.”
