The amount of money swishing around in the “zero energy” buildings market is predicted to rocket by 2035.
A new report by Navigant Research calculated global revenue could grow from $629.3 million a year in 2014 to $1.4 trillion in two decades.
A zero energy building, dubbed ZEB in the report, is defined as one which generates as much energy over th course of a year as it uses.
The mind-boggling leap in revenue is put down to governments, corporations and building firms trying to slash energy costs and minimise the carbon footprint of their buildings.
Noah Goldstein, research director at the company said: “A number of large-scale and interesting showcase developments are paving the way for the widespread adoption of ZEBs in a few innovative regions around the world,” he added.
The study called ‘Zero Energy Buildings’ looked at six areas: lighting, walls and roof, glazing, heating, ventilation, and air conditioning (HVAC) systems, renewable energy and finally “soft” costs, i.e. anything that isn’t a solid building item such as fees for architects or engineers.
