This thesis presents a simplified mathematical model of a residential building equipped with an air-to-water heat pump. The model is based on the building’s energy balance and accounts for transmission heat losses, ventilation and infiltration losses, heat losses through the ground, and heat gains from solar radiation, occupants, lighting, and electrical appliances. The model is implemented in the Python programming language, while the operation of the heat pump is controlled by a PID controller. In the practical part, comparative simulations are performed to analyse the effects of the building characteristics, indoor temperature setpoint, outdoor temperature, and global solar radiation on electricity consumption. The results show that both the properties of the building envelope and the outdoor conditions have a significant impact on the electricity consumption of the heat
pump. The model provides a basic assessment of the building’s energy response and enables a comparison of the effects of individual factors on the operation of the heating system.
