The BRE has carried out monitoring tests to measure the winter ventilation performance of the Portland Building, the recentlycompleted low energy building at the University of Portsmouth
Results from testing of a simple model in a wind tunnel are used to validate two computational fluid dynamics mathematical models. The results show that only the Reynolds-stress model provides a reasonably accurate representation of the inlemal flow, and that both models fail to predict the flow at the opening of the model
New office buildings in Spain are nearly always designed to be air conditioned. The architect Emilio Miguel Mitre Associates (EMMA) has designed a building which avoids air conditioning, thereby reducing energy demand. The design uses the principles of high thermal mass combined with night ventilation, reduction of solar gain during the summer months, high levels of insulation, evaporative cooling, and buried pipes to provide cooling when the external temperature rises above 30°C.
This paper outlines progress in the THERMIE Target project Energy Comfort 2000 after three and a half years. Seven of the eight buildings are under construction and the eighth will be starting on site in May 1997. The project covers the design, construction, commissioning and monitoring of the buildings which are offices, university buildings, and public and recreational buildings, together with "horizontal activities" which link the projects together.
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.
