There are 100 ways New York City’s building codes can be made more environmentally friendly simply by imposing energy-saving requirements on any new construction or renovation conducted.

Mayor Michael R. Bloomberg was presented these recommendations by a panel of recommended various options including rules to insulate glass skyscrapers and making individual apartments better manage indoor temperature.

Of course, the City Council would have to approve these recommendations but if approved, these changes could "amount to a big gain,” said the panel’s chairman, Russell Unger.

Russel Unger is also the executive director of the New York chapter of the United States Green Building Council.

New York wants to reduce greenhouse gases produced by the various buildings NY has. Experts estimate that these buildings are the source of over 75 percent of the city's total emissions. In December 2009, NY's City Council passed new legislation which required large building owners to pay for energy audits and for them to take steps to reduce energy consumption in their buildings.

Upon receiving the recommendations from the panel that Mayor Bloomberg had convened 18 months ago, Mayor Bloomberg said this "these recommendations were critical to meeting the city’s goal of reducing greenhouse gas emissions 30 percent by 2030."

Look forward to seeing how City Council decides to move forward. Will keep you posted….
