Depending on your budget, there are different ways. For my imagefilms I often use an Apture 600D in combination with a F10 Fresnel lens and barn doors. Through a window and its perfect. For less light I use an Aputure 300D with the Aputure Spotlight (you can use it in 3 different angles and with a Gobo kit you can simulate different windows). To enhance the effect you can use additional haze.
