Director of Eco Brooklyn, Gennaro Brooks-Church discusses how the Energy Recovery Ventilator (ERV) will work once it is completely installed in the Passive House building. The NY green contractor is currently renovating this entire Harlem brownstone, and the addition of an ERV is a vital part of the standards that need to be met. Essentially, the ERV lets this tightly sealed building breathe and in the process exchanges heat and humidity to keep the brownstone comfortable and help keep energy costs down.

We became NY ERV installers because our buildings are so tightly built they need additional air purification.
