Important notes
  • Dimmed power percentage, operating hours, commissioning settings, and tariff are dated planning assumptions.
  • Check product data and control settings before using this scenario estimate for a project budget.

Formulas

  • \(\displaystyle E_{\mathrm{baseline}} = P \times (h_{\mathrm{full}} + h_{\mathrm{dimmed}}) \times d / 1000\)
  • \(\displaystyle E_{\mathrm{scenario}} = P \times (h_{\mathrm{full}} + h_{\mathrm{dimmed}}p_{\mathrm{dimmed}}/100) \times d / 1000\)
  • \(\displaystyle S_E = E_{\mathrm{baseline}} - E_{\mathrm{scenario}}\)
