Building Energy Labs

Thermal Solar System Test Facilities

World-leading test facilities allowing for research of:

• Solar thermal systems under actual weather conditions and heat loads
• Up to 8 systems in parallel (side-by-side) with detailed measurements of thermal energy flows, electricity usage and temperatures
• Characterization of solar thermal collectors with inlet temperatures between -10°C and 90°C including measurements of solar irradiance, long wave radiation and windspeed

Solar Irradiance Monitoring Station 

A state-of-the-art solar radiation monitoring capable of measuring:

Solar Radiation

• Global Horizontal Irradiance (GHI)
• Direct Normal Irradiance (DNI)
• Diffuse Horizontal Irradiance (DHI)
• Longwave Downwelling Irradiance

Meteorological Data

• Wind Speed & Direction
• Air Temperature, Pressure & Humidity
• Precipitation & Hail

The monitoring station records data at one-minute intervals freely available for download here: weatherdata.construct.dtu.dk
