The way occupants use a building has a huge impact on the energy usage and room conditions. There is always going to be a difference between the energy loads and temperatures predicted by software ...

This is not a direct answer to your question, but it should answer your question. I do not think that it is the role of software makers to create algorithms to predict human behaviour. Their role ...

I do not think that it is the role of software makers to create algorithms to predict human behaviour. Their role is to create a product that adequately applies the laws of thermodynamics to a building. This is an undertaking in and of itself, and one that is more or less met at the present time. The rest relies on the knowledge of the person using the software. There is research into that, but seriously, that depends a lot on the type of building, its geographical location in the world, its location within the city/town/wilderness.

I think we expect too much out of software to do everything for us. And, if software makers DID provide such profiles, I would be against that too; if you provide default values, it discourages the user from actually doing his/her homework and making/documenting a set of realistic assumptions based on their application. Building thermal simulation should not be fool-proof.]]>
