Direct and Diffuse Radiation in New York City for uniform cloudy sky for an entire year

[jackD]

Hi All,

We are working on a project that needs to get hourly direct and diffuse radiation in New York City for a fully clear sky, and uniform cloudy sky for an entire year.

We have found some two threads regarding creating a clear sky radiation analysis and wonder if it is possible to do the same for an uniform cloudy sky.

• Creating a custom EPW for annual clear sky radiation analysis
• Building an EPW: Creating Normal Solar Radiation from a ASHRAE Revised Clear Sky Model (“Tau Model”) - #2 by chris

We also found a rough conversion from lux to w/m2 radiation that we could possibly use, running the illuminance point in time simulation choosing the clear sky or uniform sky and then converting manually; but would need to then automate the script to iterate and run each hour/yr since it only does POI.

Thanks in advance!
