This paper investigates the magnitude of influence of climate, architectural design and occupants on thermal comfort and final energy consumption in offices in different climates.
A parametric study for a typical cellular office room has been conducted using the simulation software EnergyPlus. Two different occupant scenarios are each compared with three different architectural design variations and modelled in the context of three different locations for the IPCC climate change scenario A2 for 2030. The parameters evaluated in this study are final energy consumption and adaptive thermal comfort according to ASHRAE Standard 55. The study shows that the impact of occupants on final energy performance is larger than the impact of architectural design in all investigated climates, but the impact of architectural design is predominant concerning thermal comfort. Warmer climates show larger optimisation potential for comfort and energy performance in offices compared to colder climates.
