The Kansas City Star reports that a $60 million apartment complex will soon break ground that developers tout as the largest U.S. multifamily apartment project using Passive House Institute-certified construction, a system that’s more energy-efficient than the highest LEED (Leadership in Energy and Environmental Design) building standard.

The certification requires radical reduction in energy consumption through a well-insulated building envelope and an energy recovery ventilation system that reduces heating needs in the winter and cooling needs in the summer by about 90 percent from comparable-sized apartments.
