An increaseddwelling size and a larger number of occupants directly effects the operational timeof a residentially installed micro-trigeneration system and therefore may have animportant influence on its performance and feasibility.To address these two operating conditions and help assess their impact on the microtrigenerationsystem performance, a second larger building housing 6 householdswas modelled. Rather than going through the whole process of adding additionalzones, a more pragmatic approach was adopted were, the height of each floor in thisenlarged building model was doubled (the spatial volume for each floor was hencedoubled from 330m 3 to 660m 3 ) to represent the volume taken by two apartmentsrather than one. Each floor of the enlarged building was thus modelled to representtwo apartments rather than one, with intervening floors modelled as an additionalthermal mass.
