Large building Testing
Retrotec’s multiple fan panels can be added in modules to test any building of any size. It is
very rare to require more power than the standard double blower system but if needed,
Retrotec can rent as many blowers as needed for any job.
In the UK, air leakage tests must
be carried out in accordance with
CIBSE TM23 on all buildings over
1000 sq.m. The Retrotec Model
M55 shown will test enclosures up
to 2880 sq.m. of envelope area at
the minimum allowable leakage
of 10 cu.m/hr./sq.m. It can be
expected that much larger
buildings can be tested with the
same system if they perform
better than this minimum.
Using two systems in
two doorways or in
one double doorway
will increase the
envelope area to
5,760 sq.m.
Retrotec software
will handle up to 18
blowers allowing for
testing of buildings
with 17,280 sq. m.
of envelope area.
Retrotec equipment,
software and field
training expertise
are available
immediately.
The latest draft of Approved
Document L of the Building
Regulations (Conservation of Fuel
& Power) which covers England &
Wales was published in April this
year. Following approval by the
European Commission this draft
will be finalized and published in
August 2001, becoming effective
from February 2002. From this
date all plans submitted for
Building Control approval must
comply with these new
requirements.
