Adrien,In the US, there is an organization called ASHRAE (American Society for Heatin, Refrigeration, and Air Conditioning Engineers) that publishes a lot of information about supposedly "typical" values for lighting, occupancy, and equipment gains. In my experience, the architects on real life projects have a good knowledge of what the lighting and occupancy density should be (W/m2 and occupants/m2) and that it isn't too hard to come up with a reasonable profile for how much of the full density is active at different hours of the day. Equipment gains are a bit harder. ASHRAE suggests that for a "typical" office building in the US, a low equipment density would be 5.4W/m2 (15.5 m2/workstation with computer, printer, monitor, fax, and printer at each), medium would be 10.8W/m2, medium/heavy would be 16.1 W/m2, and heavy would be 21.5 W/m2 (7.8 m2/workstation with computer, printer, monitor, fax, and printer at each). I would imagine that similar standards are published for the EU or for specific countries.

Dear TRNSYS User,
In order to estimate energy rate consumption and internal summer
temperature in residential building with Type 56, I am searching for
typical internal heat loads values (lights, occupancy, equipments like
fridges or furnaces, ...) with typical day schedules.
For example I am searching for informations just like :
TIME Internal Heat load Value
01 xx kJ/hr
02 xx kJ/hr
03 xx kJ/hr
...
12 xx kJ/hr
...
24 xx kJ/hr
This heat load profile will be repeated every day for a year.
Does anybody have this kind of informations ?
I have tried to create my own heat load profile, but temperatures given
in thermal zone are really too high (So high that heating is not
necessary in Winter!)
Thanks in advanced for your help,
King regards, Adrien
