cooling energy of 200 Wh m − 2 day − 1 , in the high range between 40-50 W m − 2

and

300 Wh m − 2 d − 1 .
The detailed measurements in a passive standard office building in Weilheim,
Germany, described above, show 30-35 W m − 2 internal loads, in a south-facing office
with 2 people and a computer workstation. In a north-facing office with 2 computer
workstations, the loads were about 50 W m − 2 . The resulting daily intern loads in
