This paper describes a pilot study testing the applicability of using building performance simulation (BPS) to quantify the impact of 28 energy saving behaviour changes on the residential space heating demand, based on a mid-terraced house located in the southwest of England. The 28 behaviour change options were collected based on a combination of literature review and expert knowledge. DesignBuilder V3.2, whose thermal dynamic simulation engine is Energyplus 7.2, was used to predict the impact of each behaviour change option on the space heating demand of the case study house. The study shows that the predicted energy saving potentials of all 28 options are consistent with general expectations, and so BPS can be used to quantify the impact of energy saving behaviour changes. However, using this methodology in real applications to help occupants save energy still needs more efforts.
