Stone34 building completes Seattle’s Deep Green Pilot Program

McKinstry’s design had at its heart a Multistack heat-recovery chiller.  To capture thermal energy, McKinstry created a thermal storage system that made use of phase-change material that melt and freeze at 55° F.  Helping to move all that thermal energy around is a WaterFurnace heat pump that pulls heat out of the chilled water loop. While using the heat-recovery chiller is prioritized the building also has condensing boilers from Advanced Thermal Hydronics for supplemental heat.  

Stone34 was required to curb energy and water usage by 75 percent and reuse 50 percent of captured stor
