Looking for the best units in Chencharu Green that avoid afternoon sun? This comprehensive guide reveals the top energy-efficient units in the February 2025 BTO launch that will keep you cool and save money on electricity bills.
Chencharu Green BTO Project Overview
Chencharu Green was introduced in the February 2025 BTO launch, bringing a fresh green development to Singapore's housing landscape. Located at the intersection of Chencharu Link, Bah Soon Pah Road, and Bah Soon Pah Close, this project comprises 4 residential blocks of 15 storeys each, offering a total of 683 units.
The development features thoughtfully designed 2-room Flexi, 4-room, and 5-room flats, all classified as Standard flats under the new HDB classification system. With lush landscaping, a serene rain garden, and a roof garden atop the Multi-Storey Car Park, Chencharu Green lives up to its name with abundant green spaces.
Why Avoiding Afternoon Sun is Crucial
When selecting your unit in Chencharu Green, one of the most important factors to consider is afternoon sun exposure. Units that face the afternoon sun can become uncomfortably hot, leading to higher energy bills and reduced living comfort.
In Singapore's tropical climate, afternoon sun is particularly intense between 2pm and 6pm. Units that receive direct afternoon sun can experience:
- Walls that stay warm well into the night
- Higher air conditioning costs (up to 50% more)
- Uncomfortable living conditions, especially in bedrooms
- Increased wear and tear of air conditioner
The difference in electricity bills between a sun-exposed unit and a shaded one can be substantial - potentially $100+ per month or $6,000+ over 5 years.
Case Study: Good vs Bad Sun Exposure
To illustrate the dramatic difference sun exposure can make, here's a comparison of two neighboring units in the same development. From an inexperienced person's view, these units with similar layout might seem identical and choosing either might be okay, but without consideration of sun direction, the prospective owner might have to spend significantly more money just to cool their unit and feel significantly more uncomfortable in their home.
Why the Bad Unit is Problematic:
The master bedroom is the most uncomfortable part of the unit. It receives direct afternoon sun on one wall throughout the year, which absorbs heat and continues radiating it into the room even after sunset—making it uncomfortably warm at night. From May to August, all bedrooms get some direct sun; while the angle softens the intensity, it still adds to the overall heat and affects comfort.
Why the Good Unit Works:
This unit is well-shielded from the harsh afternoon sun by the neighboring unit. It receives gentle morning sun during parts of the year, which helps remove humidity from the bedroom and living room—keeping the spaces dry and comfortable without being too bright for sleeping in.

Chencharu Green Best Units That Avoid Afternoon Sun
Best 2 room unit: 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.
Best 4 room unit: 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.
Best 5 room unit: 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.

Frequently Asked Questions
What makes a unit "best" for avoiding afternoon sun?
The best units are those where living areas (bedrooms, living room) face away from the afternoon sun path. 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.
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.
