A new McGraw-Hill Construction report states that 2009 will be a tipping point for green building. The report predicts that within two years sustainable buildings will comprise 16 percent of large corporations' real estate portfolios. Why? Because energy costs are the largest controllable expense in office buildings.
McGraw-Hill cites the following payback on green commercial real estate: 8-9 percent decrease in operating costs; 7.5 percent increase in building value; 6.6 percent ROI improvement; 3.5 percent occupancy increase; and 3 percent rent increase.
