What is the weighted average equivalent of GWP for refrigerants?

The weighted average equivalent of Global Warming Potential (GWP) for refrigerants is an important consideration in the context of sustainability and environmental impact. The correct answer indicates that a GWP of 10 or less is a benchmark for refrigerants considered to have a minimal contribution to global warming.

This threshold aligns with the goals of the Estidama Pearl Building Rating System, which emphasizes minimizing environmental footprints and promoting the use of low-impact materials and technologies. Refrigerants with low GWP are crucial in reducing greenhouse gas emissions associated with cooling systems, which are significant contributors to global warming due to their high-energy consumption and potential leakage.

In contrast, refrigerants with a GWP of 100 or greater, or those falling within the ranges provided in the other options, would represent a higher environmental impact and be less favorable within the framework of sustainable building practices fostered by the Pearl Building Rating System. Therefore, the significance of keeping GWP at 10 or less reflects a commitment to reducing harmful effects on the climate and aligns with the principles of sustainable design and construction.
