Why Avoiding Afternoon Sun is Crucial
In Singapore's tropical climate, the afternoon sun can turn your home into an oven. It leads to:
- 🔥 Unbearably hot bedrooms — even with fans, solar films and curtains
- 💸 Higher aircon bills — often up to 50% more
- 🌙 Walls that radiate heat well into the night
- 🧰 Faster wear and tear on aircon units
For those working from home or children studying, the heat isn't just uncomfortable — it affects focus, well-being, and can cause fatigue or headaches.

Chencharu Vines: Our Analysis on Which Units Minimize Afternoon Sun
Based on our sun analysis, here are our recommendations for units with minimal afternoon sun exposure:

Best 2 Rm Unit: Block 965B Stack #204
Direct afternoon sun hits only in 3 months of the year at a slight angle so the heat would be tolerable.
Best 3 Rm Unit: Block 964B Stack #144
The direct sun hits in some parts of the months of the monsoon so that eases the amount of direct sun hitting the rooms. If selecting middle to lower units, opposite blocks might be able to block out the sun in the late afternoons.
Best 4 Rm Unit: Block 965B Stack #208
Completely blocked from the afternoon sun by neighbouring unit. Partially blocked from the morning sun for some parts of the year. This might be good for people who prioritize a cooling unit but might not be ideal for those who enjoy a little bit of morning sun each day.
Best 5 Rm Unit: Block 965B Stack #198
Completely blocked from the afternoon sun by neighbouring unit. It's also north south facing which means that it catches the wind and would be more airy.

Frequently Asked Questions
What makes a unit "best" for avoiding afternoon sun?
The best units are those where main living areas (bedrooms, living room) face away from the afternoon sun. This means avoiding west orientations, though the exact sun path varies throughout the year.
Are there other factors I should consider besides sun direction?
Absolutely! While sun direction is crucial for comfort and energy costs, you should also consider factors like proximity to amenities, floor level, facing direction for views, and privacy from neighboring blocks.
