St. Pat’s Project Receives the Diamond Award from ACEC

April 19, 2018 / Industry News, PWGC News

We are thrilled to announce that PWGC has been awarded an ACEC-NY (American Council of Engineering Companies) Diamond Award for the second year in a row! Our geothermal project for the St. Patrick’s Cathedral received the Diamond Award for the Energy category.

The Diamond Awards are the highest honor presented at the Engineering Excellence Awards Gala—honoring innovative projects in categories such as building/technology systems, water resources, and energy—in recognition of their impact.

A major design challenge posed by the St. Pat’s restoration was the need to improve the cathedral’s climate control and energy efficiency without damaging the architectural integrity of this historic landmark. The final design has a smaller physical footprint than the previous HVAC system, with 10 underground wells completely out of sight, which allowed restorers to preserve the historic façade of the largest Gothic Catholic cathedral in the country.

The geothermal heating and cooling system was designed to reduce the building’s energy consumption by 30% while reducing the CO2 emissions by 94,000kg, making the cathedral project among the most sustainable restorations in the city to date. Unlike many other geothermal projects, the St. Pat’s geothermal design allows it to simultaneously heat and cool different areas of the cathedral with a more precise climate control.

We are proud to be recognized for our achievements in the restoration! Many thanks to our project partners Landmark Facilities Group Inc. and the wonderful staff at the cathedral.
