How can I calculate energy savings using LandVac vacuum glazing?
2025-01-15
To calculate energy savings using LandVac vacuum glazing, follow the following steps:
Determine the U-Value
First, please compare the U-value of LandVac with your current glazing. LandVac vacuum glazing has a U-value as low as 0.4 W/(m²·K)1. This measures the rate of heat transfer through the glazing.
Suppose we have a living scenario below:
Current Glazing U-Value: 2.0 W/(m²·K)
Annual Energy Consumption for Heating and Cooling: 10,000 kWh
Cost of Energy: $0.12 per kWh
Window Area: 50 m²
First, calculate the reduction in heat loss by comparing the U-values: Heat Loss Reduction= {2.0 - 0.4} {2.0} \times100% = 80%
Next, estimate the energy savings based on the annual energy consumption: Energy Savings= 0.80\times 10,000kWh = 8,000 kWh
Then, Convert the energy savings to cost savings by multiplying by the cost of energy: Cost Savings=8,000kWh times $0.12 per kWh=$960
Last, to find the savings per square meter of window area: Savings per m²=$960/50m²=19.20m²]
Under the simulation above, your annual energy-saving data with LandVac vacuum glazing is:
Energy Savings: 8,000 kWh per year
Cost Savings: $960 per year
Savings per Square Meter: $19.20/m² per year
Of course, additional considerations like local climate, building usage, window-to-wall ratio, etc could also affect the final results.
Notes: All the calculations and results, including the numbers and data, are only for reference.
