Multi-family units and apartments use significantly less energy than single-family homes. Although this isn’t new, the size of the units compared to homes is not the reason.
In fact, even with split incentive programs and fewer windows, energy use in larger apartment buildings has fallen 38 percent since 1980, according to the U.S. Energy Information Administration.
Energy efficiency improvements have largely been focused on single-family homes or commercial buildings, but efficiency for multi-family properties could be a $3.4 billion energy efficiency opportunity.
“Tailored solutions for the increasing number of apartment dwellers are a niche only a few have tackled. Thirty percent of new homes in 2012 were multi-family buildings with more than five units, the highest rate since 1986.”
