SYSTEM 4
CONTINUOUS MECHANICAL SUPPLY & EXTRACT
VENTILATION WITH HEAT RECOVERY
A continuous balanced mechanical central supply and extract system to
be positioned in loft or cupboard space. An integral heat exchanger
recovers a large percentage of heat energy that would have otherwise
been lost. In employing this type of system, there is no need to install
background ventilators in the dwelling.
CONTINUOUS SUPPLY AND EXTRACT
1 Determine the whole building ventilation rate from
Allow for in ltration by subtracting
- for multi storey dwellings: 0.04 x gross internal volume of dwelling
3
heated space (m )
- for single storey dwellings: 0.06 x gross internal volume of dwelling

heated space (m )
2 Calculate the whole dwelling extract rate at
adding the individual room rates for
3 The required air ow rates as as follows:
Maximum Extract Rate (boost)
The Minimum individual room extract rates sholuld be at least those
given in Table 1.1A for minimum high rate
Minimum air supply rate should be at least the whole building
ventilation rate in 1 above.

Whole building ventilation rate (l/s)
In addition, the minimum ventilation rate should not be less than 0.3 l/s per m
for a two-storey building, add the ground and rst oor areas).
This is based on two occupants in the main bedroom and a single occupant in all other bedrooms. This should be used as the
default value. If a greater level of occupance is expected, then add 4 l/s per occupant.
