Of course, each type of public and
commercial building has its own set of
issues. For offices and schools, the main
ventilation priority is likely to be regulating
the temperature, whilst pubs, restaurants
and gyms will often be most concerned
with eliminating odours. Publicans may
have thought that the smoking ban would
create a more welcoming environment,
but in fact the smoke was just masking
other repellent smells such as body odour
and stale beer.
SIMPLE SOLUTION
Sustainable ventilation manufacturer
EnviroVent has come up with an
innovative solution for those managing
new build public building projects and
retrofits. The new energiVent Impact heat
recovery unit, which will be available from
January, can directly replace the former
best selling commercial ventilation unit
and recovers 73% of heat which would
otherwise be lost.
Fitted with robust plastic grilles, the
system is capable of sustaining high
impact and it is immensely durable. This is
an application that goes beyond the
limitations of traditional extract fan
technology by incorporating a state of the
art heat recovery element to deliver
significant energy savings. A compact unit
that is simple to install, the 12 inch unit is
ideal for smaller commercial and public
premises. It uses Ultra Low DC Watt
Motor Technology with a two-speed
operation and wireless manual boost
switch to provide continuous extract
ventilation.
The extracted air passes through the
robust aluminium heat exchange cell
before reaching atmosphere.
Simultaneously, fresh air is drawn into the
unit from the outside and is filtered before
being warmed by the heat exchanger and
delivered back into the room. The system
has the facility to be switched to a designed for rapid, no fuss maintenance, significant acoustic benefit. As the noise
