Cho Shields Gramercy Enerfit

We are supplying windows and to a gut-renovation of a Manhattan townhouse and have completed an analysis of energy costs and comfort levels comparing the existing single pane windows to (a) Energy Star windows and doors (b) our own Certified Passive House windows.

The differences between the three options are staggering and gives food for thought to anyone considering a deep retrofit project. Certified Passive House windows provide exceptional comfort whilst also realizing significant energy savings.
