From the Triangle Business Journal reports there are two new laws taking effect today tha affect Contractors and Material Manufacturers:

Private contractors could benefit from HB 110, which prohibits the state from requiring that contractors enter into labor union agreements as a condition of performing work on public construction projects. The bill is intended to encourage competition and level the playing field for non-union contractors seeking governmental construction contracts.
Contractors and building material manufacturers will be impacted by the implementation of energy-efficiency standards for major building projects. HB 628 mandates that major projects be designed so that the calculated energy consumption is at least 30 percent less than the same building built to 2004 standards. Major renovations will be required to have 20 percent less energy consumption than building renovations did in 2004
