Web2 giorni fa · U = 1/R = 1/0.35 = 2.86 W m –2 K –1; This answer is very close to the value of 2.7 W m –2 K –1 given in Table 2 for air-filled double-glazing, though this also takes the heat loss through the window frame into account. WebIn theory a difference in U-value of 0.1 units corresponds to about 9 kWh/m² glass per year. The difference between 1.6 and 1.2 is 0.4 units. Thus the saving is (difference in U-value) x (additional consumption) x (area of glass) = 4 x 9 kWh/m² x 30 m² = 1.080 kWh/year. With an energy cost of 0.20 €/kWh the difference is 216 €/year.
