Re: [TRNSYS-users] Internal Heat Load in Residential Building
Adrien,
The US DOE Building America program also has developed a protocol for evaluating energy efficiency measures in single-family homes. You can find the document at http://www.eere.energy.gov/buildings/building_america/pdfs/40968.pdf
It includes predetermined internal gains based on occupants of single-family homes in the US.

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.
Kind regards,
David
