Hi,
Does anyone have experience with calibrated simulations? Especially, in accordance with ASHRAE guideline 14, or other standards / guidelines.

I've been working on a calibrating and EnergyPlus model to measured gas HVAC data for a single family house with extensive monitoring and detailed information available and I am finding it very difficult to achieve the <= 30% CV RSME that Guideline 14 suggests.

I'm surprised that it is this challenging because I have far more information available than what would likely be available in typical modelling jobs. Eg. ACH rating, measured ground temperature data, full as-built plans, indoor temperature measurements....

So I'm curious to hear about anyone else's experiences with this. Is this guideline generally achievable for modellers?

Thanks,

Hayes Zirnhelt
