Getting To Net Zero Energy Buildings With Electronically Tintable Glass

The US and EU goals for reaching net zero energy across all commercial buildings are extremely challenging. There are also many questions related to the definition of a Net Zero Energy Building (ZEB): Is it net zero sit energy? Net zero source energy? Net zero carbon emissions? However, whilst there are many possible definitions, it is clear that the route to achieving any of them is first and foremost through improving energy efficiency.
