I speak to a Real Estate developer, who gives me her views on how the real estate business is being transformed because of consciousness relating to its carbon footprint. A multistoried commercial or residential property has many tools available for it to decarbonize - of course there is a cost element, higher for exisiting buildings and a little less for brand new construction. Power sources, and smart zone based sensors, coupled with behavioral changes, will go a long way towards decarbonization.
