Solar windows cut emissions, energy use by 40% in glass skyscrapers

The US National Renewable Energy Laboratory (NREL) has modeled the benefits of PV in highly glazed skyscrapers.From pv magazine USA Tall, windowed skyscrapers loom over many major metropolitan areas. These highly glazed buildings are not particularly efficient, but newly published research in One Earth shows that PV windows can help considerably. "There are preconceived notions of what an energy-efficient building looks like, and it usually is not highly glazed, and it probably isn't very tall," said Lance Wheeler, a scientist at NREL. "We found that there are other ways to build high-efficiency ...
