In an executive order issued at the end of 2012, NY Gov. Cuomo directed state agencies to improve the efficiency of their buildings 20% by 2020.
Going forward, energy efficiency will be considered as a standard part of the capital project planning process.
To implement this efficiency initiative -- among the most ambitious in the U.S. -- Cuomo also announced the start of "Build Smart NY," the implementation arm of the Executive Order.
Using energy data on state buildings, the implementation plan prioritizes the largest, least efficient buildings first for comprehensive whole building retrofits, to get the biggest bang on energy savings for every dollar spent.
Identifying buildings with the most opportunity to improve is a big part of driving energy savings, but it's not as simple as it appears. Data from New York City shows that some of its oldest buildings are more energy efficient than those that are LEED-certified.
Efficiency measures include the typical, but all important lighting upgrades, advanced heating, ventilating and air-conditioning systems, efficient electric motors and automated energy management systems.
