As the world’s fifth largest economy and a pioneer of environmental laws and policy, all eyes are on California as it turns its attention to freeing its buildings of emissions. Ensuring new houses are equipped with solar panels and that they use no more renewable energy than they consume over the course of the year are top of the list, but existing houses and commercial buildings are also in line for an overhaul as part of the state’s bid to be carbon neutral by 204518/April/2019
