WebThe SI unit of irradiance is watts per square metre (W/m 2 = Wm −2 ). The unit of insolation often used in the solar power industry is kilowatt hours per square metre (kWh/m 2 ). [12] The Langley is an alternative unit of insolation. One Langley is one thermochemical calorie per square centimetre or 41,840 J/m 2. [13] Web– The system should be able to meet the required heating, cooling and dehumidification load in any situation. The cooling and dehumidification load can exclude hydronic systems, in particular radiators. The cooling capacity of a ceiling is about 60 W/m2 and of a floor about 30 W/m2, which is sufficient for many applications.
