Think About this--why is the use of ACs going up. Is it purely comfort. Is there something in our building design, urban planning which pushes us towards use of air-conditioning. It is already said that most of the modern buildings are energy intensive, giving a total go-by to energy saving concepts like ventilation and use of sunlight.
could not agree more. maybe, on a behavioural note, it makes sense to start discussing about the life-cycle costs (inclusive of energy and other maintenance charges) of buildings. how about having a life-cycle energy cost line item, alongside the estimate for a building? Will it focus stakeholders into paying greater attention to more energy efficient buildings? will property taxes, with a green component (though difficult to design) be an effective policy nudge to promote energy efficient buildigns?
