Important notes
- Use dated product standby data, measured settings, and tariff assumptions for planning support.
- Record the source and date of standby wattage before using this estimate in a project review.
Formulas
- \(\displaystyle P_{\mathrm{standby}} = n \times P_{\mathrm{device}}\)
- \(\displaystyle E_{\mathrm{year}} = P_{\mathrm{standby}} \times h_{\mathrm{day}} \times d_{\mathrm{year}} / 1000\)
- \(\displaystyle C_{\mathrm{year}} = E_{\mathrm{year}} \times T\)
Estimate annual standby energy and cost from control devices, product standby watts, hours, and dated tariff assumptions.
Lighting Control Standby Load 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.
