A parametric tool for combined overheating and daylighting

With energy efficient strategies focusing on reduction of the heat losses, indoor daylight has been compromised, downgrading the health and comfort needs of their occupants. The paper presents a Grasshopper 3D tool for simultaneous assessment of overheating and daylighting. A parametric analysis of two reference offices in Danish context using the developed tool is presented. The results indicate the challenge of adequate daylight in deep offices and the problem of overheating in shallow ones. Large glazing areas are preferable in deep offices in orientations with low solar radiation, choosing the right window types. Additionally, wider and higher-placed windows benefit daylight access.
