Why Avoiding Afternoon Sun is Crucial
When selecting your unit in Tanjong Rhu Parc, 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.

Frequently Asked Questions
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.
