01How is the U-value of a wall build-up calculated from its layers?
02A wall has a clear-wall U-value of 0.56 W/m2K, but a row of un-broken steel brackets adds a 25% bridging penalty. What is the effective U-value, and what fixes it?
03What do SHGC and VLT measure, and what does a cooling-dominated Indian facade want?
04A glass has SHGC 0.27 and sits behind an external shade with a shading factor (ESF) of 0.55. What is the effective SHGC?
05Indoor air at 24 C and 55% RH has a dew point of about 14.4 C. A single-glazed inner pane cools to 13 C. What happens, and why does interstitial condensation matter more?
06A 10 m2 wall at Rw 40 dB has a 0.1 m2 open vent at Rw ~5 dB. The composite Rw drops to about 25 dB. What principle does this illustrate?
07In India's energy codes, which statement is correct as of 2026?
08A residential facade computes to RETV 17.2 W/m2 against the ENS limit of 15. The solar gain term dominates. What is the most effective fix?
