Pike Block is a redevelopment of four historic buildings located at the corner of the 300 block (South Salina Street and East Fayette Street). This highly visible project introduced the area to the 1st geothermal heating system in an urban setting. IPD:E thought literally “outside the box” and developed a system that tapped into the natural underground brine aquifer that flows beneath the City of Syracuse to provide HVAC to the ground floor commercial tenants. The upper residential floors received central variable refrigerant volume (VRV) HVAC systems. The building received a central domestic hot water system that is preheated by a solar thermal array. In addition, a rain water collection system was developed so the flow of water into the sewer system could be regulated to reduce the strain on the already taxed sewer system.
