14 To precool or not to precool? Precooling Operate tower at night Not all night Electricity Electricity Usage Usage (kwh) (kw) (Δ, (Precooling - No Precooling) Start gtime Load 10% Load 50% In ideal case, can save 10%+ of energy cost for pumps/towers Careful: can also cause energy penalty. Other control learnings GHX Include a bypass On cooling setpoint ~7 10 o F below tower On heating setpoint at a high value (~60 o F) To Separate Borefields
15 Should we avoid heating hybrids? Heating dominated: Multifamily in Wisconsin Some complexity with boiler hybrid; could consider direct heat Preheat Baseboard Vestibules Basement UHs Other control learnings Boiler On setpoint should be ~5 10 o F below the GHX Facility staff should maintain this setting Boiler could sometimes be less expensive to operate than GHX
16 What about the heat pumps? Use Optimal Start Including delayed ventilation start Use partial economizer Consider accessibility and return air Webinar reminders
