Why Yishun sees this kind of mould

Yishun is a mature northern town with a mix of 1980s–1990s HDB blocks and newer BTOs at Yishun Green, Nee Soon Vista and Chong Pang. Its low-rise density and proximity to Lower Seletar Reservoir and Yishun Pond keep ambient humidity elevated, while older blocks have ageing bathroom waterproofing membranes and original aircon trunking prone to condensation.

How this is calculated: live layer 60% — moisture & mould risk 30, outdoor air 20, thermal 10, from NEA humidity, temperature, rainfall, PSI and PM2.5 by reporting zone. Structural layer 40% — housing age and waterproofing 15, exposure 10, density and shading 8, our field record 7. Same 0–100 scale and bands (Excellent 85+, Good 70+, Fair 55+, Poor 40+, Critical under 40) as the Home Wellness Index. UV and noise are national context only and never scored.
What it is not: a measurement of any individual home. For an address-level score, use the Aira Hales Home Wellness Index.
