Dear All,

I am in the process of making a NC submittal for an industrial facility. The energy supply system is based on Gas Engine Elect  Generators and their waste heat is used to run the Absorption AC Cooling system. The electricity is also available from the utility grid. There is no space heating but waste recovery boilers.I have doubts in the following aspects:

1. What should be specified as the Principal Heating Source in filling EAp2 Table ? Fossil Fuel, Electricity or Solar/Site Recovered

2. What should be the fuel type to be used in Baseline energy cost estimation?

Thanks in advance.
