Greenest Building in Pittsburgh

Center for Sustainable Landscapes, the sustainable landscapes feature the reintroduction of 150 native, non-invasive plant species.The many gardens restore natural landscape function to the site, provide wildlife habitat, and offer educational opportunities. Rain gardens and bioswales serve ecological and aesthetic functions, as well as capture site stormwater to allow natural infiltration.


Net-Zero Building Systems

The CSL building pursue both net zero energy and water management as well as energy generation. A concept design energy model for the CSL showed an Energy Use Intensity (EUI) of 19 kbtu/sf‐year with an energy usage for the building at 117,623 kwh per year. During the 2013 calendar year, the CSL was net positive on energy by 3,425 kWh, with an actual EUI of 20 kbtu/sf‐year.

Mechanically, the building is primarily served by an efficient, low-energy-consuming Under Floor Air Distribution (UFAD) system. The heart of the building's HVAC operation is the Tricoil energy-recovery system by Sensible Equipment. The system, which is supplemented by the building's natural ventilation and under-floor ductwork air-displacement strategy, also provides air-conditioning and heating with help from energy recovery.
