Advanced simulation applications using room

ROOM is a dynamic thermal simulation model that has been continuously developed at Arup over the last 30 years.  It remains one of the principal tools used for thermal modelling within Arup.  The programme includes detailed representation of complex geometry and building constructions, radiative heat transfer and air movement.  ROOM is particularly suitable for determining environmental conditions and heating and cooling loads in spaces such as atria, naturally ventilated buildings and shopping malls. Arup have developed new bespoke versions of ROOM for specific applications.  Examples include comfort modelling of stadia; outdoor microclimate design; and solar towers for power generation.  The aim of this paper is to describe how ROOM has been adapted to model these non-standard spaces and give examples of their use.
