NGO Sustainability, in its effort to promote the use of renewable energy, organized a Solar Tour in Battery Park, New York City. The architects who planned Battery Park used many innovative and unusual approaches in integrating solar energy into the facades and rooftops of the buildings. For example, entrance canapés have solar panels. Also, the façade and side of The Solaire Building has solar panels integrated into beautiful blue glass. In addition, there are features such as recycled wastewater, solar tracking, rain gathering, green roofs, and highly efficient other sources of energy for heating and cooling. All these features were explained by the leading solar installer responsible for much of the work at Battery Park City, Anthony Pereira, Board Member of NGO Sustainability.
