Comparison: SDVoE vs Crestron NVX

Facts, figures, and sources

Data sources – Jan 25, 2023

• Global electricity prices
• Crestron DM NVX 351 spec sheet
  Spec sheet footnote : “To prevent possible instability issues, it is recommended that the PW 2412WU power pack (sold separately) be used.”
• Crestron BOM figures from Crestron town hall event

Calculating power savings cost

• 35 W (Watts) – 7 W = 28 W wasted by FPGA
• 28 W for 24 hours = 672 W-h (Watt hours) daily
• 672 W h daily * 365 = 245,240 W-h annually
• 245,000 W-h = 245 kW-h
• Multiply 245 kW-h by local electricity rate
• Germany commercial rate: $ 0.462/kW-h
• 245 kW-h * $0.462/kW h = $113

Customize for your scenario

(P₁ – P_S ) * 8.76 * C_e = S_a

P₁ = power consumed by 1g endpoint (W)
P_S = power consumed by SDVoE endpoint (W)
C_e = power cost at your location ($/kWh)
S_a = annual power savings per endpoint ($)
