Greenstone on Fifth Community Building at Blue Ridge Apartments in Charlottesville, Virginia is a 3,531 square foot, two-story commercial building that was certified in the EarthCraft Light Commercial (ECLC) green building program in 2014. Greenstone on Fifth partnered with Southface to analyze building design and performance and identify areas for improvement through the U.S. Department of Energy-sponsored Advanced Commercial Buildings Initiative. Actual building performance data was collected with circuit-level energy monitors and temperature sensors deployed for one year post-occupancy. Southface studied hourly energy simulation modeling and building monitoring data to assess the actual performance of energy efficiency strategies implemented at Greenstone.
