Solar Control by Façade Orientation
Façade orientation affects the timing and angle of solar exposure, but it is not the only design input. Surrounding shade, glazing, room use and occupancy hours determine the required filtering, shading or room-darkening layer.Why it matters at project stage
Low-angle light may dominate east-facing rooms in the morning and west-facing rooms later in the day, while south façades vary seasonally. North-facing rooms can still need privacy or screen-glare control.
Information required
Review solar exposure times, surrounding obstructions, glazing data, room function, glare locations, view requirements and the distinct roles of internal and external shading.
Reaching a project decision
Internal treatments support glare, light and privacy control; external shading is a separate performance layer requiring project-wide assessment. Select fabrics against actual transmission and view objectives.
Coordination through delivery
Share objectives between the façade consultant, architect, lighting designer and curtain specialist. Verify any sensors or controls with their manufacturers and the controls team.
Project checklist
Points to resolve in the project
- Are exposure times understood?
- Were surrounding shadows considered?
- Is glazing data available?
- Were glare locations checked?
- Are internal and external roles separated?
