LSHTM has aimed to exceed its obligations for renewables. With building-services design from Downie Consulting Engineers, the project incorporates chilled beams using cooled water from geothermal bores; natural ventilation and heat-recovery units; and three mini wind turbines and 60kWp of photovoltaic cells on the roof.
These cells also act as a 'solar screen' to areas where heat gain and glare could arise. The south courtyard building uses groundwater for cooling, from a minimum depth of 100m. Heating is to be provided through a district main from a combined heat and power plant located nearby. Ventilation incorporates heat recovery at 80 per cent efficiency, lighting is all daylight controlled and there is demand-led control on all environmental systems. This project demonstrates the possibilities for low- and zero-carbon technologies in an urban setting. The new building should generate 60 per cent of its own energy. A funding application for the proposed technologies has been submitted to the Low Carbon Buildings Programme (a Stream 2B Grant). Essential enabling works have been finalised and the main works have begun on site. The project is due for completion in March 2008.
