According to Jessica Lawrence
One radical and definitely disruptive idea that could change the business model for real estate is creating a building that generates rather than uses energy. As technology advances, a savvy business person could use building benchmarking data to identify buildings that have low energy use profiles, acquire them, perform deep energy retrofits, and equip them with energy generating flooring and cladding, thereby creating an entirely new income stream.
According to the International Energy Agency
A significant share of the potential to improve energy efficiency – 80% of the potential in the buildings sector and 50+% in industry – still remains untapped.
