Looking for the best units in Sembawang Beacon that avoid afternoon sun? This comprehensive guide reveals the top energy-efficient units in the July 2025 BTO launch that will keep you cool and save money on electricity bills by avoiding the afternoon sun.
Sembawang Beacon Project Overview
Sembawang Beacon was introduced in the July 2025 BTO launch, bringing a fresh green development to Singapore's housing landscape. Located at the intersection of Admiralty Link, Admiralty Lane and Canberra Road this project comprises 4 residential blocks of 40 storeys each, offering a total of 775 units.
The development features thoughtfully designed 2-room, 4-room and 3-Gen flats, all classified as Standard flats under the new HDB classification system.
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.
