The Tools of Passive House Efficiency. 


The successful execution of any NYC high performance building shell would not be possible without windows that includes the highest thermal glass values, detailed craftsmanship and a contiguous & thoughtful application of gaskets creating the tightest closing window possible. Add to that the Landmark Preservation Committee requirements for historic continuity and you have the herculean task of turning some of the most beloved and beautiful buildings around NYC into future proof energy efficient gems.

sgBUILD is focused on bringing building efficiency to all corners of the market and has worked tirelessly on creating market specific solutions, like the Passive House historic window, in order to realize the goal of high performance building at the same cost of construction across the entire NYC building market.
