Monodraught first launched the Windcatcher system in 1991 and we launched our iconic X-Air product in 2010. In the last two decades around 27,000 Monodraught Windcatcher systems have been successfully installed in UK, France, USA and New Zealand.
We estimate that to date our products have saved almost 390,000 tonnes of CO2, the equivalent of over 3,534 million miles in a small car. As one of our signature systems, the Windcatchers have played a significant part in that saving.
Natural ventilation supplies fresh air to a building or room by utilising the passive effects of wind speed or differences in internal and external air pressure. It is a sustainable, low carbon ventilation system that does not use fans making it extremely cheap to run whist providing a comfortable and healthy indoor environment.
Ten out of ten
In October this year, our flagship Windcatcher X-Air system turns 10! It comes with our ten-year installation guarantee and also a ten year “no leak” guarantee, ensuring the system will perform in any weather.
The Windcatcher X-Air system is the perfect solution for new or refurbished buildings that require the benefits of sustainable, low carbon and secure natural ventilation such as school classrooms, dining rooms, science rooms, lecture halls and libraries, sports halls, offices and reception areas, visitor centres and restaurants and prisons
The importance of ventilation during COVID-19
Natural ventilation is as valued as ever, especially this year as part of some of the measures to deal with COVID-19. Many schools and work places are recommending that windows are kept open where possible to increase ventilation in a room. As we move further into Autumn and Winter good ventilation could be the key to reducing the spread of coronavirus.
There is evidence that Covid-19 can be spread by very small particles which are released by an infected person when they cough, sneeze, talk and breathe. Although it can be difficult to definitively prove airborne transmission, we recommend increasing the rate of supply of outside air to occupants wherever it is practical as a precautionary measure. To minimise the risks of airborne transmission of SARS-CoV2 the general advice is to increase the air supply and exhaust ventilation, supplying as much outside air as is reasonably possible, according to guidance from CIBSE.
The underlying principle is to dilute and remove airborne pathogens as much as possible, exhausting them to the outside air and reducing the chance that they can become deposited on surfaces or inhaled by room users.
Where natural ventilation systems like Windcatcher have been installed, we have provided guidance to our customers on keeping systems running by over-riding “standard” settings, avoiding using mechanical ventilation where air may circulate to other rooms and keeping windows open where possible.
Variety of applications all improve sustainability and comfort
We have a wide range of projects on our website, but have highlighted three to show the range of applications of this low energy system.
Peppa Pig World
Paulton’s Park have won multiple awards for their innovative green design and architecture. Monodraught were specified for a second time in 2014 to deliver a natural ventilation solution. Both installations allow the attraction to minimise its impact on the environment by using virtually no energy to ventilate the buildings, benefitting both the local environment and reducing long-term running costs for the business.
Littleport Academy was opened in 2018 and achieved a “very good” BREEAM rating, one of the key sustainability measures was to install a range of Monodraught ventilation solutions including our HTM “hybrid “ventilation system. The Windcatcher X- Airs were installed to provide low energy natural ventilation in spaces such as the Sports Halls, dining rooms, staff rooms and reception areas.
Sandymouth Holiday Resort
Monodraught were specified to provide both natural ventilation and natural lighting systems to serve the restaurant and bar area. The X-Air and Sunpipe systems serve the new restaurant area and bring an impressive amount of natural light and fresh air into the building.
Staff and visitors benefit from improved indoor air quality (IAQ) and a sense of wellbeing from having more natural light delivered inside the building.
Happy Birthday X-Air – here is to the next ten years of innovation!
