I am modelling a project receiving chilled water from the district cooling plant with an ice storage and wondering how to account for energy use shifting in the building model if I use Option 2 Full Accounting DES.
The guideline, Treatment of District or Campus Thermal Energy page 22, says “For thermal energy storage, the percentage of peak or mid-peak thermal energy shifted to off-peak periods in the building model shall be identical to the value metered or modeled in the district energy plant”
Does this mean I need to have the following in my building model?
1) an air-cooled chiller so I can input the average efficiency of the district cooling plant
2) an ice storage that has the same percentage of peak or mid-peak thermal energy shifted to off-peak periods as the district cooling plant.
Appreciated any suggestion!
