Chencharu Green Sun Analysis
Our recommendations for units with the least afternoon sun exposure
Why Avoiding Afternoon Sun is Crucial
1. Heat Retention
Concrete walls absorb afternoon sun and radiate heat indoors well past midnight.

2. No Easy Fix
Fans, tinting, and curtains help a little but none fully solve it.

3. WFH & Daily Discomfort
Sun-facing rooms make it hard to study or work from home without aircon running all day.
See discussion on Reddit →The good news? You can avoid all of this by checking your unit's sun exposure before you pick your unit.

Chencharu Green: Units With the Least Afternoon Sun
Based on our sun analysis, here are our recommendations for units with minimal afternoon sun exposure:
Top 2 Rm Pick: Block 967A Stack #109
Unit #111 blocks out all the afternoon sun for you so your house would not suffer from afternoon heat all the way to the night. However, this may not be true for people selecting the top few floors of this stack as the sun can still hit the bedroom in the later part of the afternoon.
Top 4 Rm Pick: Block 967A Stack #123
This is one of the most shaded units in the whole estate as the afternoon sun is completely blocked by the common corridor.
Top 5 Rm Pick: Block 968B Stack #195
Like the best 4-room unit, this unit is mostly shaded by the common corridor and unit #197. However, note that in some days of December, some direct sunlight might hit a small portion of the bedroom beside the living room. This should still be tolerable as it's a small portion for just a few days in the year.

What should I look for when choosing a unit to avoid afternoon sun?
Pick units where bedrooms and living areas face away from the west. The sun path shifts throughout the year, so a per-unit analysis is more reliable than a compass check.
How accurate is the sun analysis?
We use the project's coordinates and actual floorplan data to calculate how sunlight enters each room throughout the year.
Does the analysis consider how deep the sun penetrates into my rooms?
No. Sun depth depends on how surrounding buildings or structures block sunlight, which is difficult to model. The tool gives you a gauge of the direction that the sun enters the unit, not the depth.
Does the analysis factor in surrounding buildings?
We account for adjacent units and corridors within the same block. Other buildings in the development that may block the sun are not modelled due to data limitations.
I've already selected my BTO unit — is this still useful?
Yes. Knowing your sun exposure helps plan renovation, like where to place curtains, your study desk, or whether every room needs aircon.
Why focus specifically on afternoon sun?
Morning sun is mild. Afternoon sun (12pm to 6pm) is far more intense and heats concrete walls that radiate indoors well into the evening.
