NET RADIATION BENFIT
The Net Radiation Benefit indicator compare the total amount of helpful solar radiation with the total amount of harmful solar radiation to determine a final ‘radiation benefit’ value.
WHY IS IT IMPORTANT ?
The higher the Net Radiation Benefit value, the better performing the building massing is
Create a sky of Harmful Summer Solar Energy (T>22°)
Create a Sky of Helpful Wnter Solar Energy (T<12°)
NRB>22 – 22° based harmfull Radiation
NRB<12 – 12° based helpfull Radiation
NRBt – Total Net Radiation Benefit (Total (Helpful-Harmfull))
