From initial construction to eventual renovation or replacement, every building uses energy, water, and raw materials while generating waste and atmospheric emissions throughout its life cycle. International treaties, governmental and industry regulations, building codes, and third-party certifications have evolved in the past few decades to minimize the negative impacts that buildings impart on the environment. These rising standards cause periodic changes in the materials and methods used by the design and construction industries. Most recently, a trend in climate regulations has focused on lowering the global warming potential (GWP) of substances used in the manufacture of various building components, from insulation products to air conditioning and refrigeration systems.
