- Tasa de transferencia de calor, medida en watts.
- Conductividad térmica, medida en watts por metro-grado Celsius.
- Ancho de la ventana de vidrio, medido en metros.
- Altura de la ventana de vidrio, medida en metros.
- Espesor de la ventana de vidrio, medida en metros. 
- Temperatura interior del vidrio, medida en grados Celsius.
- Temperatura exterior del vidrio, medida en grados Celsius.
