Owners of 61 properties Downtown and on the North Shore agreed to cut energy, water and transportation consumption by 50 percent by the year 2030 as part of a national campaign to conserve resources. The effort -- called the Pittsburgh 2030 District -- sponsored locally by the Green Building Alliance, represent 38 percent of the Downtown business district and more than 23 million square feet of office space. As part of the effort, owners of the buildings will look for ways during the next 18 years to cut consumption, whether it's by installing new lights or windows, or replacing older or inefficient heating and cooling systems. Pittsburgh is one of three cities that have signed up for the challenge. The others are Seattle and Cleveland.
