Mechanically assisted ventilation

Portcullis House Ventilation System

Rotating cowls was the system adopted by Michael Hopkins and Partners with Ove Arup and Partners in the Nottingham University Jubilee Campus Figure 12.9 . This ventilation system is the successor to Hopkins' and Arup's innovations at the Inland Revenue HQ also in Nottingham, and Portcullis House, Westminster. These led to a low pressure mechanical system linked to heat recovery via a thermal wheel which recovers 84 per cent of the exhaust heat. The mechanical system requires 51 000 kWh per year...

The National Assembly for Wales Richard Rogers Partnership

Light And Ventilation

Following devolution, the Principality of Wales was granted greater autonomy resulting in the need for an assembly building for which the Richard Rogers Partnership was appointed architects with environmental engineer BDSP. It is a classic example of architect and engineer working in concert from the earliest stage of the project. The design brief was for a building which reflected the democratic nature of government whilst also being a landmark example of low energy design. It also has to last...

Beddington Zero Energy Development BedZED

Zero Energy Town Houses

BedZED is not just another low energy housing scheme, it is a prescription for a social revolution a prototype of how we should live in the twenty-first century if we are to enjoy a sustainable future Figure 18.7 . The design was led by Bill Dunster Architects who are one of the UK's top evangelists for ecologically sustainable architecture with the services and energy strategy developed by Arup Associates. The Innovative Peabody Trust commissioned this development as an ultra-low energy mixed...

Building integrated systems

Altechnica Turbine

The Vivo building illustrates one version of a building integrated wind generating system. There is increasing interest in the way that the design of buildings can incorporate renewable technologies including wind turbines. Up to now such machines have been regarded as adjunct to buildings but a concept patented by Altechnica of Milton Keynes demonstrates how multiple turbines can become a feature of the design. The system is designed to be mounted on the ridge of a roof or at the apex of a...

Types of smallscale wind turbine

Spiralf Rmige Wind Turbine Bilder

Most small systems have a direct drive permanent magnet generator which limits mechanical transmission losses. Systems under 2 kW usually have a 24-48 volt capacity aimed at battery charging or a DC circuit rather than having grid compatibility. Up to the present, horizontal axis machines are much more in evidence that the vertical axis type even at this scale. These machines have efficient braking systems for when wind speed is excessive. Some even tip backwards in high winds adopting the...

Facilitates heat recovery

Solar Shading Light Shelf

An example of a climate facade building is the office development at 88 Wood Street in the City of London by the Richard Rogers Partnership RRP . The requirement was for floor to ceiling glazing which can create a problem of solar gain which is exacerbated by the heat from computers and, in this case, a high services loading. The facade developed by RRP and Ove Arup and Partners consists of a double glazed external skin made up of some of the world's largest double glazed units measuring 3 m X...

Unassisted natural ventilation

Lanchester Library Ventilation

Pioneers of natural ventilation are Alan Short and Brian Ford in association with Max Fordham. Their first groundbreaking building in the UK was the Queen's Engineering Building at Leicester de Montfort University Short Ford and Partners . This building has been well documented and a particularly useful reference is Thomas, R. ed. 1996 Environmental Design, E amp FN Spon. Maintaining the principle of pure natural ventilation without mechanical assistance is the Coventry University Library, the...
