Unless they are using particular spec equipment you have to use normal
domestic profiles and load/gain profiles surely. The passive house is just
the fabric and servicing strategy. The occupants, unless they are eco-wise
will be the same normal heavily consuming people in standard houses
probably. Sorry for the cynicism, but come across it all the time.
Leen,
I think that the requirement is 15 kBtu/sqft/Y for heating & cooling- and
.6 ACH50 maximum.
Possibly you will find the attached spreadsheet useful, as well as the
values pasted below (these are from a project that meet/exceed the standard)
All the best-
Specific Space Heat Demand: 4.63kBTU/(ft?yr) Pressurization Test Result:0.45

* 15kWh/(m2.annum) space specific heating energy or 10W/m2 peak
heating load. This does NOT include energy used in hot water,
cooling, fans, pumps and receptacle loads. However, gains from
these loads can offset heating energy
* 120kWh/(m2.annum) primary energy (DOES include Hot water, cooling,
fans, pumps and receptacle loads)
* N50 < 0.6ACH
* + a bunch of stuff on limiting u-values and thermal comfort
In answer to your original question (and depending on how pedantic you
want to be) I can recommend:
* PHPP already has some good default values (I thin)
* The energy star website can be used for computers and peripherals
http://www.eu-energystar.org/en/en_007.shtml
* If you have a copy of the CIBSE TM22 worksheet (let me know if you
don't) you can quickly assess other electrical loads using Nominal
power, utilisation and operational hours in the "SysPlant" tab
* For energy labelled goods you could also try the pdfs available at
http://ec.europa.eu/energy/efficiency/labelling/labelling_en.htm
they contain details of how the energy labels are derived under
standard conditions. Some of the terms will probably be a bit
vague to follow

My bad- it is .6 ACH50

In SI, the main Passivhaus criteria are:
* 15kWh/(m2.annum) space specific heating energy or 10W/m2 peak
heating load. This does NOT include energy used in hot water,
cooling, fans, pumps and receptacle loads. However, gains from
these loads can offset heating energy
