Jonathan,
I have not reviewed your IDF in detail, but here are some ideas:
- I'm guessing that because you've set the Pool Heating System Maximum Water Flow Rate = 0, that no pool heating occurs.
- I have not used the (relatively) new indoor Pool object in E+, but E+ needs to know at least a couple of things in order to calculate pool heating energy
- a peak evaporation rate andÂ
- a schedule for diversity of the evaporation (e.g., active vs. inactive periods in the pool)
- Since evaporation represents a heat loss equivalent to ~950 BTU/hr, the load on the pool heater is the product of the peak rate and the diversity fraction.
- If you have a dehumidification system, the evaporation is also a latent load for your dehumidification system. This can be represented with an OtherEquipment object, as shown below (but may be included in some fashion by the Indoor Pool object).
- If you want to get more detailed, and assuming the pool is built into the ground, you might also consider defining the pool as a "basement" zone with walls of the same material as the pool sub-surface walls and a heating system which maintains that zone at the pool's water temperature
I hope this helps.
