Monodraught - Natural Ventilation / Daylight / Cooling

Windcatcher Natural Ventilation - Sun Pipe - Sunpipe Natural Daylight - Passive Ventilation

Monodraught celebrates 40 years at the top

Natural ventilation, daylighting and cooling specialist Monodraught celebrated its 40th Anniversary in March 2014. Renowned for its Windcatcher®, Sunpipe® and Cool-Phase® 'natural' systems, Monodraught has established itself over four decades as the UK's most innovative creator of award winning, low energy solutions for the building services industry.

Natural Ventilation

Monodraught Windcatcher® systems encapsulate prevailing wind and carry that fresh air down into the room below to provide natural ventilation. The system is divided internally into four quadrants so that the leeward side of the system creates a negative pressure, causing an extract at high level which removes stale air and CO² from the building. In addition, the system utilises passive stack and buoyancy principles. Volume control dampers within the system regulate the amount of ventilation, according to requirements. Windcatcher® natural ventilation systems can 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.

Windcatcher® Range - The range includes the classic GRP units which can be manufactured in square, circular and oval as well as feature turret systems. The manufacturing process allows for special bespoke designs and sizes to be provided to suit the exact building requirements to any BS and RAL colour. Recent innovations have led to the launch of the Windcatcher® X-Air range manufactured from recyclable materials with excellent structural and UV stability. The patented corner fin accommodates a patented LED architectural lighting feature, which allows a range of optional colour preferences to be specified.

Actilouvre® / Sola-Boost® - Actilouvre® modulating aerofoil technology features specially designed louvre blades that combine to minimise resistance and maximise airflow. Both Windcatcher® ranges include the option of solar power assisted natural ventilation with Sola-Boost® variants. The natural ventilation range has been strengthened with the introduction of the Ventsair® Louvre System designed to suit a variety of different building façade applications. The system provides controlled fresh air during the day and secure night time cooling via cross flow and stack ventilation.

STILL INNOVATING: THE HYBRID THERMAL MIXING SYSTEM

Typical of Monodraught's commitment, exactly 40 years after it was founded, the company has unveiled another creative and innovative product - Hybrid Thermal Mixing System (HTM). This exciting new product is designed to provide a mix of air from natural and hybrid ventilation for winter, with the ability to deliver secure night time cooling and boosted levels of ventilation in the summer. HTM is designed to meet the requirements of the Priority Schools Building Programme by combining exceptionally low specific fan powers and an intelligent control system as standard, which includes a full data logging facility, temperature control and CO² control.

3D Windcatcher® Library - To help architects and consultants deliver low maintenance, energy efficient designs within the built environment, IES have developed a library of predefined 3D Windcatcher® representations that can be dragged easily onto a building model. The authentic textures will offer architects and designers a means of understanding the aesthetics of Monodraught systems and how best to integrate them into the building.

Natural Daylight

The Sunpipe® system maximises the concept of renewable energy by reflecting sunlight and normal daylight down through a silver coated base mirror-finish aluminum tube. By installing these systems, at least 75% of the electricity used for the lighting during daytime use can be saved and a considerable saving in carbon emissions can be achieved. Other key benefits include the quality of the natural light within the building and the positive effects on those occupants therin.

Sunpipe® Design - The Sunpipe® system is designed around 3 basic sections. At the top of the Sunpipe® is patented diamond dome made in high impact resistant polycarbonate. The dome is designed to maximise the penetration of natural daylight through the flat prisms. Underneath the dome is the silver coated mirror-finished aluminum tube which conveys the natural daylight into space. By use of adjustable elbows, the system can be installed on virtually any roof pitch. Attached to the bottom of the aluminum pipe is the polycarbonate diffuser. The diffuser has been designed to allow a maximum spread of natural daylight within the space to ensure an even light distribution. There is virtually no heat loss in winter months and solar gain is minimised during summer months.

Natural Cooling

Cool-Phase® is a low energy cooling and ventilation system that creates a comfortable, fresh and healthy indoor environment while reducing, the running costs of our buildings. Cool-Phase® uses a thermal battery store utilising a Phase Change Material (PCM) in combination with intelligently controlled air handling unit to actively cool and ventilate the building.

The Cool-Phase® system can maintain temperatures within the comfort zone, while radically reducing energy consumption by up to 90%, compared to a conventional cooling system. Unlike conventional cooling approaches, Cool-Phase® uses no refrigerants, making it an environmentally sound solution for cooling our buildings.

3D Cool-Phase® Library - To help architects and consultants deliver low maintenance, energy efficient designs within the built environment, IES have developed a library of predefined 3D Cool-Phase® representations that can be dragged easily onto a building model.
