November Green Building Tour Recap: Building Towards Resilience

November 28, 2017

It’s been five years since Hurricane Sandy hit the East Coast, leaving a trail of destruction in the New York area.  During the “Building Towards Resilience” Green Building Tours event, Henry Gifford of Chris Benedict R.A., led a tour through 327 and 334 East 8th Street – two Lower East Side buildings that were affected by the hurricane – providing a firsthand look at renovations that were made in the aftermath of the natural disaster.

 

The tour began in the noisy basement of 334 East 8th Street, with a description of the damage after Hurricane Sandy, including the conditions that the workers had to endure. The elevator in this building is not counteracted by weights to lift the elevator car, but instead uses oil mixed with other chemicals in a hydraulic elevator machine.  As the water rose to about six feet above the basement floor, the oil and chemicals mixed with the flood waters, creating a hazardous condition for workers.  The slippery mix of oil, water and sewage caused the superintendant to get a foot infection that landed him in the hospital for three days.

 

Mold was another concern.  The basement doors and the top floor doors leading to the roof were left open to keep humidity in the basement low enough to prevent mold – a tactic that proved successful.  After the flood waters receded, none of the gypsum board in the basement needed replacement.

 

The flood water stayed in the building for three days, and left the building without electricity and heat until repairs were made. To protect against future flooding events, the hydronic boiler system was moved from the basement to the roof.  This move has an added benefit; the much shorter chimney pulls almost no cold air through the boiler when it’s hot but not firing, reducing annual fuel use by an estimated 30-40%.

 

Due to space constraints, not all of the electrical equipment could be relocated above the flood level. The building’s main electrical switch was replaced with a stainless steel model with holes drilled into it, to allow it to allow for drainage after a flood. Only the most water-sensitive electrical equipment, meters and circuit breakers, were moved up to the first floor.

 

Special thanks to Henry Gifford for his time, and to everyone who came out to support the progress of green building in NYC.
