·Efficient external facade design
·Exposed termal mass, night purge, natural ventilation
·Combined Heat ande Power (CHP)
 
The University of Edinburgh appointed Bennetts Associates in ­­August 2003 to design a flexible academic building on a large inner city site at Potterrow, Edinburgh. The academic user are the School of informatics and the School of Philosophy, Psychology and Language Sciences.
The external facade design focused on creating the correct proportions o solid/ glazing that ssatisfied technical factors of maximising daylight but minimising solar gain. Dayligth optimisation design took account of the quality of natural light rather tan just quantity. The high Windows reflect the Georgian nature of much of Edinburgh’s historic architecture giving varied levels of daylight across celular romos that users can flexibly respond to Ultimately an efficient glazing ratio of 60/40 solid to void was arrived at and high performance glass specified where necessary with solar control on south and west facades.
Displacement ventillation is installed throughout with termal recovery at roof top plant room level. Air is supplied at temperaturas close to normal conditions throuthout this year.
Mechanical cooling is avoided whenever posible by combination of exposed thermal mass, night purge, natural ventilation to perimeter,, internal control of solar gians and reduction in external solar gian. The carbon emissions of the active cooling have been reduced by utillising chilled wáter from the University’s tri-generation Combiend Heat and Power (CHP) system .
The building was designed in advance of the local authority requirements foro n-site renewables contribution from this size of development. However, from the outset the building was designed to make use of the installation of high-efficiency, low NOXboilers and the campus wide CHP that the University has invested heavily in. The building has no bollers and theradiators are fed directly from the neightbouting CHP. In the summer this same facility provides a cheap and efficeient source of chilled wáter that the building also utilices for peak lopping on the hottest days. The CHP system has been estimated to reduce CO2 emissions by a further 30% over and above passive and active measures.
