A wide range of dynamic shading systems is available. The way these systems are controlled can have an important impact on building energy efficiency and on occupant comfort and wellbeing. This Information Paper gives guidance on whether to use automatic or manual control or a mixture of the two, and describes control strategies and ways to implement them. It will be of interest to building designers, services engineers, shading manufacturers and installers. It replaces BRE Information Paper 12/02, which is now withdrawn.
