Evaluating the thermal performance of windows in HDB renovations (metrics)

Frequently Asked Questions

SHGC, or Solar Heat Gain Coefficient, measures how much solar radiation passes through a window as heat. A lower SHGC means less heat enters your HDB flat, keeping it cooler.
U-value measures how well a window insulates. A lower U-value indicates better insulation, reducing heat transfer and keeping your HDB flat cooler in Singapores hot climate.
Visible Transmittance (VT) measures the amount of visible light that passes through a window. A higher VT allows more natural light into your HDB flat, reducing the need for artificial lighting.
Consider Low-E glass, double-glazed windows, and tinted glass to improve thermal performance. These options reduce heat gain and keep your HDB flat cooler.
Look for contractors with experience in HDB renovations and a good reputation for quality workmanship. Check online reviews and ask for references to ensure they can properly install energy-efficient windows.
Consider using curtains, blinds, or external shading devices like awnings to block sunlight and reduce heat gain. Planting trees or shrubs outside your windows can also provide natural shade.
