Cost of Net Zero
It's no wonder the interest in net zero buildings has increased over the last few years. The number of buildings that have achieved net zero energy or are working towards net zero energy has more than doubled since 2012. According to the Portland, Ore.-based New Buildings Institute's (NBI) "2014 Getting to Zero Status Update" report, there were 60 such buildings in 2012 and by 2014 that number jumped to 160. NBI's 2013-14 Progress Report has the number of verified and emerging projects up to 191 for 2015.
