Abstract
The energy consumption of buildings depends on the infrared (IR) properties of both the atmosphere and the building envelope. The energy balance for a building's skin [1, 2]: ε σ T04 = k' (Ti-T0) + αk (Ta-T0) + εJ + αs Js states that in the steady state the power lost by IR radiation equals the incident power. The energy influx from the inside of the building k' (T.-T), atmospheric counterradiation εJ (long-wave), total absorbed solar radiation αS JS (short-wave) and convective heat transfer αk (Ta -To).
