Windcatcher Natural Ventilation Systems using
Balanced Flues
Monodraught Windcatcher systems encapsulate any
prevailing wind and carry that wind force down into the room below
to provide a constant supply of fresh air for natural ventilation.
The system is divided internally into four quadrants so that the
leeward side of the system acts as a passive stack for removing
stale air from the building. Volume control dampers within the
system are programmed to control the correct rate of ventilation,
according to the building requirements. No matter which way the wind
blows, one face of the Windcatcher system will always act as air
intake. The Monodraught Windcatcher systems eliminate the need for
air conditioning during summer months and provide all the benefits
of free night cooling without compromising the security of the
building, since the dampers open fully at midnight to allow the cool
night air to purge the building of stale air and they automatically
close again at 7am.
SunCatcher Systems
The Monodraught SunCatcher system provides
controlled natural ventilation by utilising the Monodraught
Windcatcher method and this is combined with the Monodraught SunPipe
natural daylight system. As with the Windcatcher arrangement, the
prevailing wind pressure carries a continuous fresh air supply,
through weather protected louvres, down into the room below,
slightly pressurising the internal space. Warm stale air is expelled
from the room by the principle of differential temperatures and
natural buoyancy of air movement on the opposite side or leeward
side of the system.
The heart of this SunCatcher system is the
mirror-finish aluminium SunPipe tube which reflects and intensifies
natural daylight down into the room below producing the equivalence
of up to 1200 Watts of natural light.
SunPipe Systems
Monodraught SunPipes consist of silverised,
mirror-finish aluminium tubes that carry sunlight down into the room
below. There is virtually no limit to the length of SunPipe or the
number of bends that can be used and the SunPipe system terminates
in the patented Monodraught SunPipe Diamond dome, which seals the
pipe against the ingress of rain, dust or insects. A special ceiling
diffuser seals the bottom entry of the SunPipe at ceiling level
creating a long column of still air, which acts as an excellent
insulator against heat transfer. Accordingly, there is virtually no
heat loss in winter months nor solar gain during summer months.
Monodraught manufacture a range of 10 different sizes from 230mm to
1500mm diameter and Monodraught’s Design Team provides a full design
service. A full installation service is also provided across the UK.
Sola-powered Systems
With the ever-increasing threat of global warming
and rising energy prices, Monodraught decided to incorporate solar
power into their Natural Ventilation systems wherever possible. This
has resulted in four new products; Sola-vent, Sola-boost, Sola-signal,
and Sola-extract. Sola-boost only works under sun power during
summer months but increases the throughput of ventilation air by
250%. Sola-vent is the solar powered bathroom extract vent, which
also incorporates the SunPipe for energy-free operation and Sola-extract
is used in conjunction with cross flow ventilation, typically from
openable windows, to provide powered extract ventilation – but
without any electrical power. Sola-boost systems are available in
either circular or square format and are manufactured in a wide
range of sizes to suit every application.
Sola-signal is still under development but will recognise the Buxton
time signal and, therefore, operate the controls totally based on
this radio signal.
Special Shapes & Finishes
There is virtually no limit to the style and
design of all the Monodraught system range to complement any
building design. The most popular shapes are square, round, and
rectangular, but oval or hexagonal shapes can be produced. The
standard material for Windcatchers is glass fibre but SunPipes are
manufactured in polycarbonate with vandal proof ABS flashings.
News
Monodraught has seen a consistent and steady
increase in turnover of 35% for the last five years, now with a
turnover of £15m per annum. Monodraught offer a complete service for
contracts throughout the UK.
