This study has been performed as a complement to the graduate studies of Yonghui Jin at the National Institute of Occupational Health and the Royal Institute of Technology. It was initiated by the need to analyze free convective flows along vertical walls within the test chamber employed for experimental work with particle transport in turbulent buoyant plumes.

 Natural convection in a thermally driven square cavity filled with air is studied numerically. Since the thermal Rayleigh number of the configuration ranges between 108 and 1012, the flow is turbulent and k-& models are used to predict the behavior of the flow. For this natural convection problem, the viscous sublayer must be discretized and the behavior of the turbulent quantities is damped within this sublayer through low-Reynolds number modelling.

Two new halls of residence, designed by Rick Mather Associates, are currently under construction at the University of East Anglia. All 800 of the near-identical student rooms have en-suite, prefabricated bathrooms, designed to be craned into position. Their low energy design required high standards of air-tightness and that mechanical ventilation systems be threaded through the buildings.

Throughout the past decade, a considerable amount of experience has been gained from technology transfer programmes on energy efficiency and renewables energy technologies in the UK. This paper describes theessential elements of a successful technology transfer programme and gives details of some of these elements within the UK Department of Energy's Best Practice programme, its predecessor the Energy Efficiency Demonstration Scheme and the Renewables Energy programme.

The European Community's Thermie programme is outlined, covering financial support for commercial implementation of new energy technologies; measures for energy technology promotion, through a network of Organisations for the promotion of Energy Technology (OPETs), and coordination of technology promotion activities at European level. If future funding is to be secured for Thermie and other technology promotion programmes, their relevance to the key political challenges of the day must be shown.
