Anatomy of an Energy Efficient Building Exhibit

Identifying strategic opportunities to improve the performance of these systems, the exhibit offers actionable insights to help New Yorkers save energy, reduce costs, and meet the City’s ambitious new climate action requirements, while improving comfort and livability.
