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
