A thermal simulation model and suitable weather data were used to generate design curves for the application of night ventilation cooling to office buildings. The work was carried out under the programme of the International Energy Agency (IEA) Annex 28 on 'Low Energy Cooling'. The generated curves show the potential reduction in internal peak day temperatures throughout the cooling season, the free cooling provided by night ventilation and the number of hours that a fan would run during the night for mechanical systems to achieve this free cooling.
This paper describes and discusses the energy saving design features of the Learning Resources Centre at Anglia Polytechnic University. As part of the University's policy on environmental conservation, the design brief for this new Queen's Building specified a low energy passive design solution. The building, which has been occupied since September 1994, was awarded a THERMIE grant to demonstrate a 50% reduction in the annual energy related carbon dioxide emissions for a building of this type.
