3.4 Facade Impact on Shading


Advertisement

Facade
the facade controls the amount of daylighting access to the interior. Therefore, it reduces the amount of solar gains (thermal performances) Implementing WWR into my façade design also allows outdoor views for the users and dos not disrupt the outdoor view from the interior
Before optimise
Advantage : full height curtain wall with single glazed glass panel maximises view towards all direction of the building
Disadvantage : interior space might be overly exposed to solar radiation and natural lighting

Solution: Reduce window to wall ratio (WWR) to 1/3
Before rotating 90° to the east
After optimise
Changes :
• 1000mm planter box are introduced to levels with cantilever balcony
• 1/3 aluminum horizontal louvres are also implemented onto the Western façade
After rotating 90° to the east
Built in planters on the balcony enhances visual interest creating a more settling environment In addition, these vegetation decrease solar radiation gains towards the surfaces of building Avoiding direct sunlight into the interior


Advantage : less solar radiation into the interior of the building
Disadvantage :does not have enough daylight as the building was facing south
Solution: Building should be reorientated to the east Then 1/3 double façade will be implemented
Changes :
• 1/3 aluminum horizontal louvres are implemented onto the eastern façade However, WWR is ineffective as more daylight should be introduced into the interior of the working space
• Vertical aluminum louvres are implemented for ground floor as the floor to ceiling height is 8000mm. This will allow more daylight into the Lobby
