This paper presents a preliminary study of energy performance and window systems in two detached houses located at northern and southern Europe respectively. Based on simulations using DesignBuilder (+EnergyPlus), the impact of a series of wall window sizes and a shading device on primary energy demands (heating, cooling and lighting) has been mainly investigated. In addition, two different window systems were tested according to their thermal and visual properties (U value, g value and VT). The achieved results concluded a design strategy: a larger window size could be adopted to balance energy and daylight requirements with an energy-efficient product and well-designed shading system.
