Sustainable development is good business. Whether reducing utility costs through energy-efficient or low-flow equipment, or daylighting and improving indoor air quality to increase employee productivity through healthier, happier workers, the result is a better bottom line. The John A. Roebling Son’s Company Building 114 in Trenton’s Wire Rope District is a good model. An early 20th century wire rope factory, the building was designed to perform in a less energy intensive era, making it perfectly configured to meet the challenges of the 21st Century. Evenly lit throughout by roof monitors and large factory windows, Building 114 minimizes the need for artificial lighting for most tasks. The radiant heating pipes that line the perimeter walls will be relocated under the floor slab when the slab is replaced to install tenant power and data conduit.
