Improving solar data in CIBSE climate files – Survey of measuring networks and test on daylight simulation
conference contribution
posted on 2019-04-04, 12:44 authored by Eleonora Brembilla, John MardaljevicJohn Mardaljevic, Anastasia MylonaThis paper investigates the influence of solar radiation models on Climate-Based
Daylight Modelling (CBDM) evaluations. The solar radiation model currently
implemented in CIBSE files is compared with high-accuracy reference data, and a
new approach based on measured data and separation models is proposed. An
in-depth survey of solar radiation data currently available for British locations is also
presented. The analysis on solar radiation data and models showed that the current
climate files under-estimate all irradiance components, whereas a combination of Met
Office data and the Skartveit separation model can drastically improve irradiance
estimates. The use of this improved model to derive irradiance values led to a
significant improvement in the reliability of CBDM results as well.
