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.

What makes a unit "best" for avoiding afternoon sun?

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.
How accurate is the sun analysis?
Our analysis uses precise astronomical calculations to determine sun paths throughout the year, ensuring you get accurate information about sun exposure patterns for each unit.
