DEFINITION

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.

UNITS

kWh/m2

WHY IS IT IMPORTANT ?

The higher the Net Radiation Benefit value, the better performing the building massing is

METHODOLOGY

Create a sky of Harmful Summer Solar Energy (T>22°)

Create a Sky of Helpful Wnter Solar Energy (T<12°)

Compute Helpful-Harmful

INDICATORS

NRB>22 – 22° based harmfull Radiation

NRB<12 – 12° based helpfull Radiation

NRBt – Total Net Radiation Benefit (Total (Helpful-Harmfull))
