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
- \(\displaystyle E_{\mathrm{baseline}} = P \times (h_{\mathrm{full}} + h_{\mathrm{dimmed}}) \times d / 1000\)
- \(\displaystyle E_{\mathrm{scenario}} = P \times (h_{\mathrm{full}} + h_{\mathrm{dimmed}}p_{\mathrm{dimmed}}/100) \times d / 1000\)
- \(\displaystyle S_E = E_{\mathrm{baseline}} - E_{\mathrm{scenario}}\)
Estimate annual energy and cost savings from a full-output and dimmed-output lighting schedule.
Dimming Savings Scenario Calculator is a planning aid. Keep the target source, product data, measurement method, and project assumptions with the result. Confirm compliance, installation, certification, and safety decisions with the responsible professional.
