AI Thread Summary
The discussion focuses on calculating heat gain through windows in the UK, specifically for vertical surfaces facing north, south, east, and west. The user has encountered significant discrepancies among data from a glass manufacturer, a net-based calculator, and the BRE standard assessment procedure. They express a preference for the net-based calculator but seek additional reliable standards or models for accurate heat gain figures. The conversation highlights the need for consistent and dependable data in energy rating assessments for houses. Reliable sources for heat gain calculations remain a key concern for the user.

I am doing a few calcs regarding heat gain through windows and I am looking fot some typical values to apply for vertical surface NSE&W.
I currently have figures from a glass manufacturer, a net based calculator and the BRE standar assesment proceedure ( for energy rating houses).
All three are wildly different with the net based one looking most likely , but does anyone know of any standards or models that can provide a reliable figure I can use.
many thanks in advance

I am leaning further to the net based calculator now.
But does anyone have any knowledge of gain figures or any idea where to find them

Thread 'Mechanism of Energy Conservation in Zero-Amplitude Sum of EM Waveforms'

Assume that this is a case where by sheer coincidence, two sources of coherent single-frequency EM wave pulses with equal duration are both fired in opposing directions, with both carrying the same frequency and amplitude and orientation. These two waves meet head-on while moving in opposing directions, and their phases are precisely offset by 180 degrees so that each trough of one wave meets with the crest of the other. This should be true for both the electric and magnetic components of...
